HDPE drainage pipes are manufactured using PE100 or PE100-RC polyethylene (PE) compound as raw materials. The production equipment employs internationally advanced polyethylene pipe extrusion lines, featuring a unique screen basket die design, an advanced barrier-type screw, and an IKV forced feeding extrusion system. These ensure thorough melting and plasticization of the raw materials, guaranteeing excellent resistance to slow crack growth (SCG) and rapid crack propagation (RCP) in the polyethylene pipes during use. Additionally, the production line is equipped with fully automated computer control systems, including FLX ultrasonic scanning devices, meter weight measurement control systems, and wall thickness monitoring controllers, which dynamically control the product during the manufacturing process to ensure production quality.

The product offers advantages such as good flexibility, strong corrosion resistance, lightweight, and excellent impact resistance. The pipes are connected using methods like thermal fusion socket, thermal fusion butt welding, and electrofusion welding, integrating the pipes and fittings into a single unit. This results in a safe and reliable system with low construction costs. The dimensions and performance of the PE pipes comply with the requirements of the CJ/T358-2019 standard.
