Installing underground composite pipes at fuel stations is a precision job where small mistakes become buried, hard-to-reach failures. This guide covers the practical workflow for double-layer HDPE/EVOH composite pipes, the pipe and fitting range from Luoyang Wohong Petrochemical (Ai Yuan brand), and the field checks that separate a 30-year installation from a re-dig. Why the […]
How to Select and Install Underground Composite Piping for Fuel Dispensing Systems Underground fuel piping is the lifeline of any service station. It carries gasoline, diesel, and ethanol blends from storage tanks to dispensers, and it must do so safely for decades without leaks. For procurement teams, site engineers, and contractor crews, understanding how a

Stage III Vapor Recovery Piping: Installation and Leak-Tightness Testing for Underground Fuel Systems Stage III vapor recovery moves the vapor-handling work from the dispenser back to the underground storage tank, and the quality of the underground pipe run between tank and dispenser largely decides whether the system recovers vapor or just leaks it. For contractors
Underground composite fuel pipe installation demands precise fusion control, correct bedding, and careful trench preparation. This guide covers the practical, field-level workflow for laying Ai Yuan dual-layer and single-layer HDPE/EVOH composite pipes at service stations. Understanding the Ai Yuan Composite Pipe Construction The Ai Yuan fuel pipe from Luoyang Wohong Petrochemical is not a single-material
