Drainage pipes should be selected based on the drainage nature, composition, temperature, groundwater erosion, external load, soil conditions, and construction conditions. If conditions permit, underground plastic drainage pipes should be prioritized. The following specifications should be observed: for gravity flow drainage pipes, underground plastic pipes, concrete pipes, or reinforced concrete pipes are preferred; drainage pipes leading to community sewage treatment facilities should use plastic drainage pipes; for special sections like crossing ditches and rivers or pressurized sections, steel pipes or cast iron pipes may be used; if plastic pipes are used, metal casings should be added (the casing diameter should be 200mm larger than the outer diameter of the plastic pipe). When the drainage temperature exceeds 40 degrees Celsius, metal drainage pipes or high-temperature resistant plastic pipes should be adopted; for pipelines transporting corrosive wastewater, plastic pipes can be used; plastic drainage pipes located under roads and driveways should have a ring bending stiffness of no less than 8kN/square meter, while those located under non-driving areas in communities and other locations should not be less than 4kN/square meter. 2. In-building drainage pipes should use building drainage plastic pipes and fittings or flexible joint cast iron drainage pipes with corresponding fittings. 3. In environments where the ambient temperature may fall below 0 degrees Celsius, metal drainage pipes should be used; drainage pipelines with continuous or frequently draining temperatures exceeding 40 degrees Celsius or instant drainage temperatures above 80 degrees Celsius, such as sanitary wastewater drainage systems in public baths and hotels with hot water supply systems, high-temperature drainage equipment, and drainage horizontal branches and horizontal risers in public kitchen facilities, should use metal drainage pipes or heat-resistant plastic drainage pipes. 4. Pressure drainage pipelines can use pressure-resistant plastic pipes, metal pipes, or coated composite steel pipes. 5. For buildings with high construction standards or quiet environments, when the noise from water flow in ordinary plastic drainage pipes cannot meet noise control requirements, appropriate sound insulation measures should be taken, such as using specially designed soundproof pipes and fittings, employing walls with good sound insulation effects (solid walls, lightweight partition walls, soundproof walls filled with foam plastic, etc.), installing rubber pads on pipe supports, wrapping sound-absorbing insulation materials around pipes at floor crossings, and setting up vent pipes for fixtures. 6. When selecting plastic drainage pipes for experimental buildings, teaching buildings, or hospitals discharging acidic or alkaline wastewater, attention should be paid to the corrosion of plastic pipe materials and joint materials by the acidity, alkalinity, and chemical composition of the wastewater. 7. In high-rise buildings exceeding 100 meters in height, drainage pipes should use flexible joint cast iron drainage pipes and their fittings. 8. Vent pipes can use plastic pipes and flexible joint cast iron drainage pipes. 9. Connection methods: (1) For UPVC, CPVC, SNA+PVC pipes and fittings, it is advisable to use matching adhesives for socket bonding; risers can also use elastic sealing rings for connection. The specifications of PVC water supply pipes mainly include: 20, 25, 32, 40, 50, 63, 75, 90, 110, 125, 140, 160, 180, 200, 225, 250, 280, 315, 355, 400, 450, 500, 560, 630, with the most commonly used specification being 110. Many friends also pay attention to the wall thickness of water supply pipes. In fact, the wall thickness varies under different pressure levels, making it difficult to summarize in one sentence. Generally speaking, manufacturers usually have specific tables to introduce this issue. Therefore, if you want to understand deeper issues such as wall thickness, it is best to contact the manufacturer's customer service. PVC Water Supply Pipe PVC water supply pipes come in a wide variety of specifications, mainly related to their performance. Due to the strong corrosion resistance, low fluid resistance, high mechanical strength, non-toxic hygiene, good water tightness, long service life, and lightweight characteristics of PVC water supply pipes, they are used in many projects, leading to a demand for various specifications. Manufacturers naturally strive to meet this demand by producing various specifications of PVC water supply pipes for everyone to choose from. Are there any installation requirements for PVC pipes? If the installation of PVC pipes is done properly, water usage will be much smoother, avoiding issues like poor water flow or blockages. Additionally, aesthetic considerations necessitate that the installation and laying of PVC water supply and drainage pipes require many methods and techniques. Below, the PVC pipe manufacturer will share the requirements and specifications for PVC pipe installation. 1. The fusion joint between the electric fusion fittings and the pipes must be kept dry. 2. The connecting surfaces of the pipes and fittings must be dry, clean, and oil-free. 3. The cut ends of the pipes must be perpendicular to the pipe axis. Pipe cutting is generally done with pipe cutters or cutting machines; if necessary, a sharp hacksaw may be used, but burrs and rough edges must be removed from the cut surface. 4. The hot-melt tool should be powered on, and operations should only begin after the green indicator light indicates that the working temperature has been reached. 5. When heating, the pipe end should be inserted into the heating sleeve without rotation, reaching the marked depth, and simultaneously, the fitting should be pushed onto the heating head without rotation, reaching the specified mark. The heating time should follow the instructions in the welding tool's user manual. 6. After reaching the heating time, remove the pipes and fittings simultaneously from the heating mold, and quickly insert them into the marked depth in a straight and uniform manner without rotation, forming a uniform flange at the joint. 7. Within the specified time, the freshly welded joint can still be adjusted, but must not be rotated. 8. When welding elbows or tees, attention should be paid to their direction as per the design drawings, marking the position on the straight direction of the fittings and pipes with auxiliary markers. 9. The standard heating time for electric fusion connections should be provided by the manufacturer, and should be adjusted according to the different environmental temperatures. 10. During installation, pipes must not be bent; when passing through walls or floors, no forced corrections should be made. The clearance with other metal pipes should exceed 100mm, and polypropylene pipes should be placed on the inside of metal pipes. 11. Indoor exposed pipes should be installed after the building finishes are completed, and pre-reserved holes should be coordinated with the construction to be 50mm larger than the outer diameter of the pipe. When pipes pass through floors, steel casings should be installed, with the casing extending 50mm above the floor. 12. Strict waterproof measures should be taken when pipes pass through floors and roofs, with fixed supports provided on both sides of the crossing point. 13. Pipes hidden beneath flooring and within walls should undergo water pressure testing and acceptance checks, and records should be kept. 14. When pipes pass through foundation walls, metal casings should be provided to ensure better installation security. PVC Pipe Specification Introduction PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about two-thirds of the market, while soft PVC accounts for one-third. Soft PVC is generally used for flooring, ceilings, and leather surfaces, but due to the presence of plasticizers in soft PVC (this is also the difference between soft and hard PVC), it becomes brittle and is not easy to preserve, thereby limiting its application range. Hard PVC does not contain plasticizers, making it flexible, easy to mold, not easily brittle, non-toxic, and pollution-free, with a long shelf life, thus having great potential for development and application. PVC has poor combustion performance, extinguishing when removed from fire, and is classified as a flame-retardant plastic. In addition, it has good electrical insulation properties, making it suitable for protective casings for wires and cables. The water pressure resistance, external pressure resistance, and impact resistance of PVC pipes are all very high, making them suitable for piping projects under various conditions, with an extremely wide range of applications. Factors Affecting PVC Drainage Pipe Prices The prices of PVC pipes vary under different conditions and demands. For example, the required pipe diameter and wall thickness specifications differ, leading to different prices. Furthermore, different brands have varying market positions, and the raw materials they use differ, resulting in differences in quality and price. It is important to note that when purchasing PVC drainage pipes, one should ensure quality reliability. The cost of PVC pipes is generally low, and the differences between brands are not significant, but the quality differences can lead to greater losses. Therefore, the quality of PVC drainage pipes is of paramount importance. Factors Affecting PE Pipe Prices 1. The raw materials used for PE pipes are a decisive factor in pricing. Some PE pipe manufacturers lower costs by using recycled materials, which do not meet pressure standards and stretch length requirements, particularly regarding sanitation. Additionally, pipes made from recycled materials have rough inner walls and contain impurities. While these pipes reduce costs, quality is significantly affected. Therefore, when selecting PE pipes, it is essential to understand market conditions and avoid purchasing overly cheap pipes. 2. Regarding the types and specifications of PE pipes, they are used in various applications now, such as water supply pipes, conduit pipes, and corrugated pipes. These pipes have differences in structure, process, and performance, resulting in cost variations. Buyers should determine the price level based on the specific type of pipe required, and differences in pipe diameter, wall thickness, and length contribute to variations in material usage and time costs, which also affect pricing. How much does PVC pipe cost per meter? This is a common question among buyers. The price of PVC pipe per meter is closely related to product categories, specifications, models, manufacturers, brands, and quality. Thus, this question is quite general. Understanding these factors clearly allows for more specific pricing based on actual situations. Prices for each type of PVC pipe can vary significantly; below are examples of PVC water pipe prices per meter. Generally, PVC water pipes are priced approximately as follows: 50*2 at 4=5.5 yuan/meter; 75*2.3 at 6=8 yuan/meter; 110*3.2 at 14-17 yuan/meter; 160*4 at 30-32 yuan/meter; 200*5 at 50-54 yuan/meter (the number after the pipe diameter refers to wall thickness in mm). The above prices are for market reference only. PVC pipes are not only used in our daily lives but are also commonly used in industrial applications. Some large buildings have PVC pipes buried underground, differing in specifications from residential use, making the application range of PVC pipes very broad. If you are interested in this product, keep reading as we introduce PVC plastic pipe prices and specifications in detail. The prices of PE100 water supply pipes are determined by many factors, including manufacturers, brands, specifications, models, pressure ratings, etc. For example, the "Dengquan" brand SDR26 nominal pressure 0.8Mpa 110mm outer diameter PE water supply pipe has a unit price of 73.43 yuan/meter (for reference only), while the SDR13.6 nominal pressure 1.25Mpa 160mm outer diameter PE water supply pipe has a unit price of 340.25 yuan/meter (for reference only). When purchasing, it is essential to determine which specifications and models to buy based on your engineering situation. Dengquan Plastic Industry's PE pipes belong to green building materials, used for both hot and cold water systems, as well as pure drinking water systems. Under specified long-term continuous working pressure, the water temperature transported by the pipes can reach 95°C. This eliminates worries about pipe scaling and clogging, as well as yellow stains and rust marks in sinks and bathtubs. The thermal conductivity is only one-fiftieth that of metal pipes, providing energy-saving insulation effects in hot water pipelines. They are lightweight, with high tensile strength: their weight is only one-eighth that of metal pipes, offering good toughness and impact resistance. The inner and outer walls of the products are smooth, resulting in low flow resistance, soft colors, and beautiful shapes. Hot melt connections are adopted, eliminating the need for threading, and a joint connection can be completed in seconds. Copper inserts are used for connections with metal pipes and water fixtures, ensuring safety and reliability. The pipe system has a lifespan of over 50 years under specified conditions. PE pipes are mainly used in urban water supply networks, irrigation projects, and agricultural sprinkler irrigation projects. The connection method using hot melt and electric fusion ensures the integration of joints and pipes, effectively resisting internal pressure and axial impact stress. Moreover, no heavy metal salt stabilizers are added during production, making the material non-toxic, preventing scaling, and inhibiting bacterial growth, thus avoiding secondary pollution of drinking water. PE pipes include medium-density polyethylene pipes and high-density polyethylene pipes. Based on wall thickness, they can be divided into the SDR11 and SDR17.6 series. The former is suitable for transporting gaseous artificial coal gas, natural gas, and liquefied petroleum gas, whereas the latter is mainly used for transporting natural gas. Compared to steel pipes, PE pipes have simpler construction processes and certain flexibility, and they do not require anti-corrosion treatment, saving a lot of procedures. However, they are less mechanically robust than steel pipes, so special attention should be paid to safety distances for heating and should not be exposed to air and sunlight, as well as being sensitive to chemicals, preventing leaks from sewage pipes that could cause harm. Factors Affecting PE Pipe Prices 1. The raw materials used for PE pipes are a decisive factor in pricing. Some PE pipe manufacturers lower costs by using recycled materials that do not meet pressure standards and have unsatisfactory sanitary conditions. Additionally, pipes made from recycled materials often have rough inner walls and contain impurities. Such materials reduce costs but significantly impact quality, so buyers should be aware of market trends and avoid overly cheap pipes. 2. The type and specifications of PE pipes also affect pricing. PE pipes are now used in various applications, including water supply pipes, conduit pipes, and corrugated pipes, each with differences in structure, process, and performance, leading to cost differences. Buyers should determine price levels according to the specific type of pipe required. Variations in pipe diameter, wall thickness, and length also contribute to differences in material usage and costs, which should be understood thoroughly. How much does PVC pipe cost per meter?

PPR Pipe Specification Indication Method: PPR fittings' nominal outer diameter (dn) refers to the nominal outer diameter of the PPR pipe connected to the PPR fitting. The wall thickness of the PPR fitting should not be less than that of the corresponding PPR pipe series S. Most companies only have the higher standard S2 series for PPR fittings, suitable for both hot and cold water. PPR Pipe Specifications: - S5 Series -------------- 1.25 MPa (12.5 kg) - S4 Series -------------- 1.6 MPa (16 kg) - S3.2 Series ------------ 2.0 MPa (20 kg) - S2 Series -------------- 2.5 MPa (25 kg) 2. PPR Pipe Specification Marking: PPR pipe specifications are indicated using the pipe series S, nominal outer diameter dn × nominal wall thickness en, e.g.: PPR pipe series S5, PPR nominal diameter dn25mm, PPR nominal wall thickness en2.5mm, represented as S5, dn25 × en2.5mm. The PPR pipe series S is a dimensionless numerical series used to indicate PPR pipe specifications, calculated as follows: S = (dn - en) / 2en. Where: - dn — PPR nominal outer diameter, unit in mm - en — PPR nominal wall thickness, unit in mm Commonly used PP-R pipe specifications include five series: 5, 4, 3.2, 2.5, and 2; PPR pipe specifications are classified into five series based on standard dimension ratio SDR values: 11, 9, 7.4, 6, and 5. PPR Pipe Specification SDR: The ratio of the nominal outer diameter dn to nominal wall thickness en for PPR pipes. The relationship between SDR and the PPR pipe series is as follows: SDR = 2S + 1. Water pipe specifications include: DN15 (4-point pipe), DN20 (6-point pipe), DN25 (1-inch pipe), DN32 (1.2-inch pipe), DN40 (1.5-inch pipe), DN50 (2-inch pipe), DN65 (2.5-inch pipe), DN80 (3-inch pipe), DN100 (4-inch pipe), DN125 (5-inch pipe), DN150 (6-inch pipe), DN200 (8-inch pipe), DN250 (10-inch pipe), etc. The meaning of water pipe Φ25×1/2 is that its outer diameter is 25, corresponding to a nominal diameter of DN20 (commonly referred to as a 6-point pipe). You can purchase a 6-point faucet or a 4-point faucet (just add an adapter between the pipe and the faucet). 1. Strong Corrosion Resistance Compared to ordinary cast iron pipes and galvanized pipes, UPVC pipes have excellent chemical stability, resistant to strong acids and bases, do not rust or scale, and do not cause secondary pollution. 2. Low Fluid Resistance The inner wall of UPVC pipes is very smooth, with a roughness coefficient of only 0.009, resulting in low fluid resistance, which does not excessively reduce water pressure, effectively improving water delivery capacity. 3. High Mechanical Strength UPVC pipes for water supply have good water pressure resistance, impact resistance, and tensile strength. 4. Health and Non-Toxic The "Dengquan" brand UPVC pipes for water supply use uniquely green and eco-friendly resin materials and non-toxic stabilizers, thus not compromising water quality or affecting human health. 5. Lightweight and Easy Installation The density of UPVC pipes is one-fifth that of ordinary cast iron pipes, making them easy to handle. They are connected using special adhesives or elastic sealing joints, allowing for quick and simple installation. 6. Optimal Temperature Performance for Water Supply Pipes UPVC pipes for water supply are best suited for room temperature; lower temperatures increase brittleness, complicating installation; higher temperatures decrease tensile strength and water pressure resistance. 7. Good Water Tightness The adhesive's bonding strength can reach over 12.5kg/cm² within 15 minutes after gluing, and over 25kg/cm² after 120 minutes. After years of use, there will be no significant decline, and the sealing rings at elastic joints also have a comparable lifespan to UPVC pipes, eliminating concerns about aging and leakage. 8. Long Service Life Under normal usage conditions, UPVC pipes have an effective lifespan exceeding 50 years.

As urban economies develop, PE pipes become a crucial facility for a city's drainage system. When purchasing PE water supply pipes, inquiries about specifications, models, quality, and prices are common. PE water pipes are widely used in urban water supply and water treatment industries due to their high strength, high temperature resistance, corrosion resistance, and non-toxicity. Hence, many friends often inquire about PE pipe specifications and prices, which is a rather broad question. Below, the Dengquan Plastic Industry team provides knowledge about what PE pipes are, PE pipe specifications, and pricing. PE Pipe Specifications and Pricing Introduction 1. What are PE pipes? When referring to PE pipes, it's easy to associate them with PE plastic, which is a common polymer material. The plastic bags we use in daily shopping are made from PE plastic. The advantages of PE pipes compared to metal pipes are quite evident, as they exhibit superior physical properties, are non-toxic, and have excellent impact resistance and stress crack resistance. PE pipes can be classified into three types: PE mining pipes, PE sewage pipes, and water supply pipes. PE mining pipes are lightweight and durable, making them particularly suitable for underground operations, such as conveying high-sulfur water (corrosion resistance), transporting natural gas, and coal gas. PE sewage pipes can be used in urban drainage systems; the quick installation speed and strong flexibility of PE pipes make them less prone to damage. Even if damaged, maintenance costs are low. Additionally, PE pipes offer safety, hygiene, ease of construction, and long service life. PE water supply pipes are commonly found in household water supply systems. The excellent water pressure resistance of PE pipes enables them to effectively withstand the impact of water, enhancing the safety and reliability of the water supply. PE water supply pipes are also used in landscaping, primarily due to their lower price compared to metal pipes. PE Water Supply Straight Pipe 2.

PE pipe specifications classification We often receive calls inquiring about PE pipes, sometimes mentioning non-standard specifications, indicating that many customers are still not very clear about the classification of PE pipe specifications. Here’s a brief overview of PE pipe specification classifications. PE pipes can be divided by pressure ratings mainly into 0.6Mpa, 0.8Mpa, 1.0Mpa, 1.25Mpa, 1.6Mpa. Mpa is a unit of pressure; for example, 0.6Mpa means a pressure of 10 kilograms. PE pipes can also be classified by diameter into: 20, 25, 32, 40, 50, 63, 75, 90, 110, 125, 160, 180, 200, 225, 250, 280, 315, 355, 400, 450, 500, 560, 630, 710, 800, 900, 1000, 1200, all in mm (millimeters), with the diameter indicating the outer diameter. The wall thickness also varies with different pressure ratings. With the knowledge above, you can purchase the required PE pipes according to your engineering needs. For non-standard pipes, such as PE conduit or PE sewage pipes, the pressure can sometimes be relatively lower, such as 0.4Mpa, which can save costs. Dengquan Plastic Industry's strict brand quality management and advanced testing equipment ensure the quality of its pipes. Its main products include PP-R hot and cold water supply pipes, PE water supply pipe series, PVC-U water supply pipe series, PVC-U drainage pipe series, PVC-U buried sewage pipe series, PVC-U ordinary electrical cable pipe series, PVC-U electrical conduit series, and more than a thousand varieties across ten series. PE (high-density polyethylene) eco-friendly drinking water pipes are made from imported PE100 raw materials according to GB/T13663 standards. These products have excellent weldability and environmental stress crack resistance, meeting international and national standards. PE pipes are mainly used for water supply and drainage pipelines, mining pipelines, and the transport of wastewater and solid or mixed media in chemical and pharmaceutical industries. The internal resistance of PE pipes is 25% lower than that of metal pipes, significantly improving transport efficiency. The raw material sources for PE are rich. From the molecular formula structure (C2H4), it can be seen that the molecular structure of PE is a simpler polymer. During development, PE pipes continually overcome their shortcomings. The heating and welding of PE require certain operational space and skilled technical execution. The invention of electric heat welding sleeves connects two pipe segments or fittings through an electric heat welding sleeve, which is used for connecting PE pipes in trenches or in confined construction spaces. The material performance of PE pipes is also being improved, evolving from PE63, PE80 to PE100. PE100 refers to a material that can maintain a minimum strength (MRS) of 10Mpa after 50 years at 200°C. PE80 has a rating of 8.0Mpa. As the grade of PE materials improves, the wall thickness of the same pipe made of PE115 will be lower than that made of PE100, allowing for reduced material usage and costs while ensuring compliance with requirements, facilitating the application of PE pipes in large diameter pipelines. The connection of PE pipes requires heating and a certain cooling time, with each welding process taking around 20 minutes. The larger the diameter of the pipe, the longer the heating and cooling time, thus extending the installation time for PE pipes.
