HDPE Drainage Pipe

HDPE drainage pipes are manufactured from high-density polyethylene resin via continuous extrusion, producing durable pipes with excellent chemical resistance and a smooth interior surface for efficient water flow. Available in DN20 to DN1200 with pressure ratings from PN4 to PN16, these pipes are ideal for gravity-fed stormwater drainage, sanitary sewer lines, and industrial wastewater transport. The flexible HDPE material withstands ground movement and seismic activity, while butt-welded or electrofusion joints ensure leak-proof connections. Compliant with AS/NZS 4130:2009 and GB/T 13663.2-2018 standards.

HDPE Double-wall Corrugated Pipe

HDPE double-wall corrugated pipe features a smooth interior wall for optimal hydraulic flow characteristics and a corrugated exterior for high ring stiffness and structural integrity. This innovative dual-wall design provides excellent load-bearing capacity while reducing material usage and overall weight. Available in DN110 to DN1200, it is specifically engineered for non-pressure underground drainage, sewer networks, and highway sub-drainage applications. Compliant with GB/T 19472.1-2004 standard, the pipe offers superior impact resistance, chemical stability, and a service life exceeding 50 years in buried installations.
