Straight Electrofusion Coupler for Double Wall HDPE Fuel Pipe

This double wall electrofusion straight coupler is a special connecting fitting for buried double-wall HDPE fuel pipelines of gas stations.
Made of high-density polyethylene with green outer anti-seepage shell and inner oil-resistant liner, it has excellent resistance to gasoline, diesel and chemical corrosion. Two groups of electrofusion welding terminals are arranged on both ends, which can simultaneously weld the inner delivery pipe and outer leakage detection pipe, forming a fully sealed double-layer integral joint.
It supports real-time leakage monitoring of the interlayer cavity, effectively preventing underground soil pollution caused by fuel leakage. Multiple sizes such as 75/63 are available, meeting the secondary containment safety standards of gas station oil pipeline systems, widely used for straight splicing of double-wall buried fuel pipelines.
