Wear Resistant PE Water Pipe GB/T13663 Polyethylene Pipe For Irrigation

GB/T13663-2000 "Polyethylene (PE) pipes for water supply"

Polyethylene (PE) water supply pipes are manufactured from specialized polyethylene raw materials through a one-step extrusion process using plastic extruders. They are plastic pipes widely applied in urban water supply networks, irrigation and drinking water projects, landfill sites, sewage collection pipeline engineering, and agricultural sprinkler irrigation projects.

Since PE pipelines are connected using heat fusion or electrofusion methods, the integration of interfaces and pipes is achieved, effectively resisting both the hoop stress generated by internal pressure and axial impact stress. Furthermore, PE water supply pipes do not contain heavy metal salt stabilizers; the material is non-toxic, non-scaling, and does not breed bacteria, thereby avoiding secondary contamination of drinking water.

• Reliable Connection Performance The polyethylene piping system utilizes electrofusion connection for quality assurance, where the joint strength is superior to that of the pipe body itself.

• Excellent Impact Resistance The low-temperature embrittlement temperature of polyethylene is extremely low, allowing safe operation within the temperature range of -60°C to 60°C. During winter construction, pipe brittle fracturing will not occur due to the material's superior impact resistance. It exhibits excellent stress crack resistance: PE features low notch sensitivity, high shear strength, and outstanding scratch resistance, with highly prominent environmental stress cracking resistance.

• Exceptional Corrosion Resistance Polyethylene (PE) pipelines can withstand corrosion from various chemical media, and chemical substances present in the soil will not cause any degradation to the pipe. Polyethylene is an electrical insulator, so it does not suffer from rot, rust, or electrochemical corrosion; moreover, it does not promote the growth of algae, bacteria, or fungi.

• Long Service Life Under normal operating temperatures and pressure conditions, PE pipelines can be used safely for over 50 years.

• Good Hygienic Performance No heavy metal salt stabilizers are added during the processing of polyethylene (PE) pipes. It is non-toxic, non-scaling, and does not breed bacteria, effectively solving the problem of secondary contamination of urban drinking water.

• Excellent Wear Resistance Comparative wear resistance tests between PE pipes and steel pipes demonstrate that the wear resistance of HDPE pipes is 4 times that of steel pipes. In the field of slurry transportation, HDPE pipes exhibit significantly superior wear resistance compared to steel pipes, which implies a longer service life and better economic efficiency for HDPE pipelines.

• Excellent Flexibility The inherent flexibility of PE pipes allows them to be easily bent. In engineering projects, obstacles can be bypassed by altering the pipeline direction, and in many instances, this flexibility helps reduce the consumption of pipe fittings and minimizes installation costs.

• High Flow Capacity PE pipes possess a smooth inner surface with a Manning roughness coefficient of 0.009. The smooth performance and non-adhesive characteristics ensure that PE pipes offer a higher transport capacity than traditional pipe materials, while simultaneously reducing pipeline pressure drops and water transmission energy consumption. The flow capacity of PE pipes is increased by more than 30% compared to other ordinary pipelines.

• Good Construction Performance PE pipes are lighter than concrete, galvanized, and steel pipes, making them easy to transport and install. The welding process is straightforward, and the construction is highly convenient. Lower labor and equipment demands translate to a massive reduction in project installation expenses. Additionally, trenchless installation methods can be adopted.
