Designing Stage III Vapor Recovery Piping with HDPE Composite Pipes

1. Introduction Installing underground composite piping systems at retail fuel stations is a precision job that directly affects long-term operational safety and maintenance costs. Unlike steel or fiberglass piping, HDPE+EVOH composite pipes have different handling, jointing, and backfill requirements. This article walks through the practical installation workflow for Luoyang Wohong Petrochemical’s Ai Yuan composite pipes, […]

Electrofusion Fitting Installation Guide for HDPE+EVOH Underground Composite Pipe Systems

Why Electrofusion Fittings Matter for Underground Fuel Piping When building or upgrading a gas station’s underground fuel system, the joints between pipe sections are the most vulnerable points. Even the best HDPE+EVOH composite pipe cannot perform reliably if its connections fail. This is where electrofusion fittings come in — they create strong, permanent, leak-free joints
