1. The insulation layer material varies according to the temperature of the medium inside the pipe, using polyurethane foam, with a usage temperature of ≤120℃. Ester foam is an ideal insulation material.
2. The outer protective casing is extruded from high-density polyethylene (i.e., PVC pipe), which has high strength and good waterproof and corrosion-resistant properties.
3. The combination of the foam insulation layer, inner steel pipe, and outer protective pipe forms a tight bond, with a shear strength between layers of ≥0.2 Mpa.
4. The compressive strength of the insulation layer is ≥0.2 Mpa, ensuring that the insulation structure does not deform under soil pressure and ground dynamic loads. The direct-buried polyurethane insulation pipe has high compressive strength, good corrosion and waterproof properties, and a long service life, making it widely applicable in centralized heating projects such as urban areas, factories, hot springs, and residential buildings, suitable for direct burial installation.

PPR insulation pipes and polyurethane hot water insulation pipes have advantages over ordinary insulation pipes:
1. The three-in-one three-layer polyurethane foam insulation pipes have anti-freeze cracking, UV resistance, and efficient insulation functions.
2. This product is a domestic innovation. The ordinary three-layer insulated water pipes currently on the market generally have insulation layers of only 3mm to 5mm, made from extruded foamed plastic, which essentially fails to achieve insulation effects. Given the significant temperature differences between northern and southern climates in China, there are currently no dedicated water pipes suitable for both regions in the market. Our PPR foam insulation pipes and polyurethane insulation pipes can adjust the thickness and density of the insulation layer according to the climate differences, with thicknesses ranging from 15mm to 150mm and densities between 40 and 60.
3. The insulation layer of this product has a fully closed-cell foaming structure, making it difficult for water from the external air to penetrate the material, demonstrating excellent resistance to water vapor penetration. Even if the surface is scratched or worn during installation, the overall gas barrier performance is not affected. Currently, rubber insulation pipes on the market have limitations in material formula and price, leading to more permeable foaming, larger pores, and poor rebound performance, which easily results in gas loss and severely affects insulation effectiveness.
4. Ordinary insulation pipes typically measure only 1.8m to 2m in length, whereas each hot water project installation generally requires about 20m to 50m, leading to numerous insulation joints and complicated installations. Additionally, installation workers usually wrap joints with tape, which ages and shrinks after one or two years, causing the insulation layer to separate and expose the inner pipe. Since the inner pipe is UV sensitive, this leads to aging and cracking. Our insulation pipes come in a standard length of 4 meters per piece, saving on connection fittings and fully meeting installation requirements.
5. The outer sleeve, insulation layer, and inner pipe of this product are tightly compacted with no gaps or air layers, resulting in outstanding insulation performance. In winter, the temperature difference of hot water in the pipes is about 3 to 5 degrees day and night. Older products have multiple joints, and due to installation needs, the diameter usually must be 2mm to 3mm larger than the inner pipe, resulting in separation between the insulation layer and inner pipe, significantly diminishing insulation effectiveness.
6. The insulation and heat retention performance is excellent, with a thermal conductivity of 0.35W/m·k, far lower than that of metal pipes, thus preventing scaling during heat conduction and frost formation during cooling, which saves external insulation material usage. At the same time, it ensures that the fluid is not polluted, is non-toxic, and is ideal for clean water projects.
7. Easy to cut and process, it can be connected with specialized fittings without the need for threading. The appearance is aesthetically pleasing, and the joints are fitted with special accessories.
**Who manufactures PPR insulation pipes and polyurethane hot water insulation pipes in Guangdong?** They are primarily used in air source hot water projects, hot spring water projects, and hotel hot water projects. Here at Guangdong Dongguan Koyu Pipe Industry Co., Ltd., we mainly produce PPR foam insulation pipes, polyurethane insulation pipes, air source hot water project insulation pipes, hot water foam insulation pipes, and prefabricated central air conditioning insulation pipes.
The advantages of insulation pipes lie in the fact that the outer protective layer of PPR hot water pipes is made of high-density polyethylene PVC pipes, while the internal pipeline consists of PPR pipes, a corrosion-resistant layer, an insulation layer, and a corrosion-resistant pressure protection layer. PPR foam insulation pipes and polyurethane insulation pipes are formed by injecting rigid polyurethane foam plastic raw material into the cavity between the PPR pipe and the outer protective layer using a high-pressure foaming machine. This is commonly referred to as the "pipe-in-pipe foaming process." Its functions are waterproofing, insulation, and supporting the weight of the thermal network. When the medium temperature is between -50℃ and 90℃, rigid polyurethane foam is used as the insulation layer. These pipes have advantages such as low thermal loss, strong compressive performance, and good waterproof and corrosion resistance, with a service life generally between 40 to 50 years. The water temperature resistance can reach 130℃. They are economically attractive and can reduce labor installation time and costs.
Guangdong Dongguan Koyu Pipe Industry Co., Ltd. mainly produces PPR insulation pipes, heat pump hot water insulation pipes, etc. PPR foam hot water pipes are suitable for industrial and civil construction, providing drinking water and hot water heating systems, and are upgraded replacement products for copper and galvanized pipes.

On November 25, 2016, the "CTC Cup" 15th National Cement Chemical Analysis Grand Comparison Summary and Commendation and Technical Seminar, organized by China Building Materials Inspection and Certification Group Co., Ltd. (CTC) and the National Cement Quality Supervision and Inspection Center (Cement Center), was held in beautiful Guiyang. The meeting specially invited Kong Xiangzhong, Executive Vice President of the China Cement Association, to attend and deliver an important speech. More than 240 people from relevant management agencies, provincial and municipal building materials quality inspection stations, cement production enterprises, equipment manufacturers, and inspection personnel attended the grand event.
Zhang Qinghua, Executive Deputy Director of the National Cement Quality Supervision and Inspection Center, delivered a welcome speech, warmly welcoming the guests and congratulating the awarded units, encouraging everyone to create new brilliance. She also detailed the fruitful results and practical significance of this national cement comparison and introduced the work carried out by the National Cement Quality Supervision and Inspection Center.
Kong Xiangzhong, Executive Vice President of the China Cement Association, first thanked the professionals working hard in the quality inspection field of the cement industry and provided a detailed analysis of the current situation and "13th Five-Year Plan" for the development and industrial policy of the cement industry. He also reported on the establishment of the Quality Committee of the China Cement Association. According to Vice President Kong Xiangzhong's analysis, this year's clinker production has not seen significant growth, and national cement output is expected to remain roughly the same as last year. With the acceleration of key projects, the proportion of high-strength cement usage is expected to increase. This year, the China Cement Association has led various provincial cement associations and large enterprises to coordinate regional markets extensively, strengthen industry self-discipline, and oppose low-price dumping, which has led to a recovery in cement prices. Coupled with rising coal and logistics costs, cement prices are expected to remain robust, and the industry’s performance for the year is anticipated to be better than last year. Since China aims to maintain rapid economic growth, there will not be large turning points in the cement industry during the "13th Five-Year Plan." Vice President Kong emphasized that the next steps for the cement industry must focus on addressing the two major issues of "excess capacity" and "increased concentration." The State Council has good policies for the cement industry, allowing large enterprises to lead the establishment of special funds for industrial structure adjustment to compensate and reward exiting enterprises. He revealed that before the end of this year, the cement association will select several provinces to establish cement management companies at the provincial level to implement this policy and accelerate the task of "capacity reduction," providing relatively high compensation for exiting enterprises. Currently, China has over 3,500 cement enterprises, and looking at the existing 10 large groups, including this year's two-material merger, the concentration is about 57%. Compared to the international top four, which have a concentration of 70%, there is a significant gap. Thus, during the "13th Five-Year Plan," there will likely be larger-scale phased reorganizations. Vice President Kong further emphasized that the cement industry will face stricter constraints on energy efficiency and environmental improvements in the future. The requirements for technological innovation and management innovation for enterprises are increasing, and environmental monitoring content is continuously being enhanced. Next year, "carbon emission reduction" targets will also be set, making it crucial for enterprises to effectively utilize "carbon asset management" to manage the challenges of "carbon reduction." With the government's push to reduce regulations and grant more powers, third-party certification will be a future development direction and a common international practice. For production enterprises, the enhancement of modern testing methods, particularly in intelligent development, will require higher personnel qualifications. He hopes that personnel engaged in inspection and testing will pay more attention to and support the application of new technologies and equipment, as well as the promotion of intelligence, which will improve labor conditions and benefit product quality enhancement and cost reduction for enterprises.
The conference specially invited Guo Li, Deputy Director of the Cement Product Review Department of the Quality Management Office of the China Building Materials Federation and the National Industrial Product Production License Office, to report on the new policy development directions for the cement industry and interpret the new "Implementation Guidelines for Industrial Product Production Licenses (Cement Products)."
