Yuxi PPR Foam Insulated Pipe, Polyurethane Insulated Pipe Price - Koyu Pipe Industry Cash on Delivery!
In recent years, PPR foam insulated pipes and polyurethane insulated pipes have become increasingly popular as the materials for insulation pipes continue to diversify and durability improves. When it comes to home renovations, consumers often feel lost when choosing insulation pipes. What material is of better quality? After all, water and electricity are "hidden projects." In modern renovations, many insulation pipes are installed within walls. If insulation pipes leak or burst, the consequences can be irreparable. Therefore, it is essential to choose high-quality products. Today, Koyu will explain some advantages of PPR foam insulated pipes and polyurethane insulated pipes. As a new type of material, PPR foam insulated pipes and polyurethane insulated pipes have unique advantages; they can be used for cold water temperature control and preservation, and can also maintain hot water for a long time. Due to their non-toxic properties, lightweight, pressure resistance, and corrosion resistance, they are becoming a new type of promoted insulation product. The joints of PPR insulated pipes use hot melt technology, allowing the pipes to fuse completely together. Therefore, once installed and passed pressure testing, there will not be aging and leakage issues over time like aluminum-plastic pipes. When the insulation layer is implemented for the inner and outer pipes of PPR polyurethane hot water insulation pipes, the foam slurry is usually poured directly between the two pipes, forming in one step. Before pouring the slurry insulation material, the inner and outer pipes must be kept in good concentricity using appropriate tools, and the lower sealing treatment must be tight to prevent slurry leakage. Depending on the flow condition of the slurry and the foaming speed, shorter insulation layers can be poured upright, while for most longer insulation layers, an inclined pouring method is adopted to facilitate slurry flow and foaming. Depending on the formula and construction requirements, the slurry can be injected from the upper side or the lower side. When the pipe fittings are longer, the slurry discharged from the mixing head can be introduced into the lower part of the pipe gap through a conduit, and as the injection amount increases, the conduit can be gradually withdrawn. This method is only applicable for manufacturing ordinary sleeve insulation layers below 3mm.
One of the key steps in the completion and acceptance of a hot water PPR insulation pipe, polyurethane hot water insulation pipe, or solar insulation pipe project is the pressure test of the PPR insulation pipe. Whether the test passes and whether there are detailed records are essential factors influencing acceptance. The pressure test of PPR polyurethane hot water insulation pipes is the immediate step following the completion of the main installation and the immediate step before system cleaning. Here, the editor from Koyu Pipe Industry will introduce the key points of the pipeline pressure test: The liquid pressure test is often used on-site in the actual construction of PPR insulation pipe networks, and we usually use water as the test medium. It is important to pay attention to the temperature of the water; when it falls below 5 degrees Celsius, heating measures must be taken to prevent the PPR foam insulated pipe and polyurethane insulated pipe from freezing. When testing pressure, we typically use 6 kg of pressure, which is somewhat general. If the supervising unit is strict, there may be issues during record-keeping. When using water for the pressure test of PPR insulation pipes, the test pressure should be 1.5 times the design pressure, and this pressure must be selected based on the design pressure. Another scenario is when the pressure test of the PPR insulation pipe network needs to be linked with equipment. If the pressure test of the equipment is lower than that of the PPR insulation pipe, the test can proceed based on the equipment's testing pressure. However, one must note that the test pressure cannot be lower than 1.15 times the pipeline design pressure, and the consent of the construction unit must be obtained. The polyurethane insulation material in PPR foam insulated pipes and polyurethane insulation pipes is currently one of the best-performing insulation materials internationally. Rigid polyurethane has excellent properties such as being lightweight, having a low thermal conductivity, good heat resistance, aging resistance, ease of adhesion to other substrates, and not producing drip during combustion. It is widely used in buildings in Europe and America for roofs, walls, ceilings, floors, doors, and windows as insulation materials. In developed countries like Europe and America, about 49% of building insulation materials are polyurethane, while this proportion in China is still less than 10%.
PPR foam insulated pipes and polyurethane insulated pipes are becoming increasingly common in our lives, known for their strong insulation capabilities. You may often hear about them but may not have much knowledge about them. Today, Dongguan Koyu Pipe Industry Co., Ltd. will provide a detailed understanding of the advantages of PPR polyurethane hot water insulation pipes: there is no need for a separate pipe trench, as they can be directly buried underground or underwater. Polyurethane insulated pipes are easy and quick to install, resulting in low overall costs. They also have good corrosion resistance and impact resistance even under low-temperature conditions and can be directly buried in frozen soil. Polyurethane direct-buried insulated pipes are made from a high-functionality polyether polyol blend, which is foamed through chemical reactions. Today, the editor from Koyu Pipe Industry will discuss the cold resistance characteristics of PPR foam insulated pipes and polyurethane insulated pipes: they possess excellent characteristics such as being lightweight, high strength, thermal insulation, sound insulation, cold resistance, strong insulation performance, non-absorbent, and easy and quick installation. PPR foam insulated pipes and polyurethane insulated pipes have become essential pipes for various hot water engineering insulation, waterproofing, and sealing. A leak alarm line can be established: during the manufacturing of PPR polyurethane hot water insulation pipes, an alarm line can be embedded within the insulation layer close to the steel pipe. Once a leak occurs in any part of the pipe, the alarm line transmits the signal, allowing a specialized detection instrument to alert and indicate the exact location and severity of the leak, enabling repair personnel to address the leaking segment quickly and ensure the safe operation of the heating network.
Advantages of PPR polyurethane hot water insulation pipes include reduced project costs. With a compensation direct-buried laying method, it addresses the thermal expansion of the pipeline through natural compensation of the pipeline and compensators (such as rectangular and corrugated pipe compensators), minimizing thermal stress. In the case of non-compensated direct-buried laying, simply put, when the pipeline is heated, there are no compensation measures, and it relies on the strength of the pipe material itself to absorb thermal stress. PPR polyurethane hot water insulation pipes are used in various indoor and outdoor pipelines, centralized heating pipelines, central air conditioning pipelines, as well as insulation projects in chemical, pharmaceutical, and other industrial pipelines. The editor from Koyu Pipe Industry explains how to solve the sliding problem of hot water insulation pipes: internal sliding and internal fixing. The working steel pipe is fixed to the outer protective pipe through a specific structural form, fully utilizing the strength and rigidity of the outer protective pipe, as well as the friction between the outer protective pipe and the soil, to further stabilize the inner pipe without needing a reinforced concrete structure. This can save construction costs for reinforced concrete supports. Only with steel pipes as the outer protective pipe can the internal fixing method be employed. The fixed end should have insulation facilities to reduce the thermal bridge effect, and the outer protective pipe should have sufficient strength to meet the requirements of the pipeline's horizontal thrust. For the steel outer steel insulation structure, adopting an internal fixing structure has significant advantages. Depending on the different types of outer protective pipes, they can be classified into steel outer steel structures and steel outer steel composite structures.

Last week (11.21-11.27), the national cement market prices remained generally stable, with slight fluctuations in some areas. Price increases were mainly observed in areas such as Liu'an in Anhui, Mianyang and Guangyuan in Sichuan, and Dali in Yunnan, with increases of 10-20 yuan/ton; prices in Haikou slightly dropped by 5-10 yuan/ton, and a subsequent price increase of 15 yuan/ton in Nanchang, Jiangxi has not yet been realized. In mid to late November, affected by widespread rain and snow, downstream demand showed weak performance, with enterprise shipment volumes decreasing by 10%-20% compared to the previous period. Due to temporary production restrictions in many areas, inventories remain at normal levels, and prices have largely stabilized.
According to the tracking situation from Digital Cement Network, except for Northeast, North China, and Northwest regions, which have implemented off-peak production in the off-season, some provinces in Central South, East China, and Southwest regions have discussed and announced production cut plans for the first quarter and the entire year of next year. It is expected that in the first quarter of 2017, cement prices will remain at a relatively high level.
The provinces in the southern region that have announced off-season production plans for 2017 include: Fujian (40 days a year), Guangdong (40-45 days a year, 20 days in the first quarter), Guangxi (40-45 days a year, 20 days in the first quarter), Hubei (80-90 days a year, 40 days in the first quarter), Sichuan (120 days a year, 30 days in the first quarter), and Jiangxi (70 days a year, 40 days in the first quarter). To stabilize prices in the off-season and create a favorable market atmosphere for the next year's opening, it is expected that other provinces in the southern region will also gradually promote similar measures.
It is important to note that before the arrival of the off-season in late December, enterprises should be cautious of rapid price declines during inventory clearance in the southern market.
