PE water supply pipe is mainly made of food-grade virgin HDPE resin mixed with antioxidants, UV stabilizers and other additives. This extruded high-performance pipe ensures safe and pure drinking water, mainly used for urban & rural tap water transmission, community water supply, landscape irrigation and factory purified water pressure delivery.

Haierde plastic winding pipe is made of high-density polyethylene pellets.
This flexible pipe is manufactured through melt extrusion and winding molding with a unique spiral T-shaped wall structure, which greatly improves ring stiffness and compression resistance. It is specially used for municipal large-diameter rainwater & sewage drainage, river sewage discharge, factory and community buried pipe networks, applicable to heavy-load roads and soft soil foundations.

Produced from black HDPE via hot spiral winding molding.

Rectangular hollow ribs are arranged between the neat inner and outer walls, delivering outstanding hydraulic performance. Widely applied to municipal rainwater-sewage diversion, residential community drainage, park pipe networks, rural drainage, and pipelines under medium backfill or light-duty vehicle roads

Manufactured mainly from high-density polyethylene (HDPE).

This new type of pipe is produced via double-layer co-extrusion, featuring an annular outer wall and smooth inner wall. It balances high ring stiffness and low water resistance, serving as the primary pipeline for rainwater-sewage diversion, drainage & sewer networks, community pipe networks, industrial sewage discharge and farmland drainage in municipal and construction projects.

Manufactured from high-strength ductile iron via centrifugal casting. Internal cement mortar lining and external asphalt/epoxy coating greatly improve pressure resistance, seismic performance and service life. Ideal for drainage under municipal arterial roads, heavy-load roads, high-rise buildings, civil air defense projects, pipe galleries and high-temperature drainage areas
