High toughness, impact resistance, low temperature brittle resistance
The product has outstanding tensile toughness, elongation at break exceeding 500%, outstanding tensile resistance, deformation resistance, and impact resistance. It is non-brittle and cracking in a low temperature environment of -40°C. It can effectively resist uneven settlement of foundation, extrusion of covering soil, and external impact. It is suitable for low-temperature construction in severe cold areas and complex underground working conditions; it complies with GB/T 19472 and EN 1046 standards.
Resistant to chemical corrosion and strong media compatibility
It can withstand the erosion of municipal water bodies, industrial clean water, acid and alkali soil for a long time, and is resistant to salt corrosion and medium erosion. The inner and outer walls of the pipe fittings will not rust, scale, or be corroded. There will be no wall thickness attenuation or leakage problems due to medium erosion. This ensures stable pipeline transportation for a long time; it complies with ISO 4433 and ASTM D1693 standards.
Hot melt butt joint, sealed and zero leakage
It is adapted to the standard HDPE hot-melt docking process and is integrally formed through end-face melting and pressure. After welding, the pipe fittings and pipes are completely homogeneous in material and structure. The interface strength is higher than that of the pipe body. It has strong pressure-bearing capacity and will not disconnect or leak under alternating hot and cold conditions or pressure fluctuations. It eliminates hidden dangers of leakage at pipe network nodes from the source; it complies with DVS 2207 and EN 12814 standards.
Strong deformation adaptability, compatible with underground laying
The product has excellent stress relaxation performance and can disperse formation stress through trace deformation. The thermal expansion and contraction performance is highly matched with the supporting pipes, effectively offsetting the structural stress caused by the thermal expansion and contraction of the pipe network. It is suitable for mainstream laying methods such as direct burial, tube wells, and pipe corridors, greatly improving the overall stability of the pipe network; it complies with GB 50236 and ISO 10460 standards.
The inner wall has low resistance and is smooth, saving energy and reducing consumption during transportation.
The inner wall of the pipe fittings is smooth and flat, with extremely low roughness, small flow resistance, and is not easy to accumulate impurities and scale. It effectively reduces the water transportation resistance of the pipe network, reduces the operating load of the pump unit, reduces system energy consumption and transmission losses, and improves the overall pipe network transportation efficiency; it complies with ISO 10838 and AWWA M55 standards.
Hygienic, safe and non-toxic, suitable for transportation of people's livelihood
