HDPE/EVOH composite fuel pipeline equipped with imported PE electrofusion fittings is a complete underground fuel conveyance system specially developed for gas station infrastructure projects. The multi‑layer composite pipe integrates high‑strength HDPE structural layers, adhesive tie‑resin layers and high‑barrier EVOH layers through co‑extrusion technology, delivering outstanding hydrocarbon permeation resistance against gasoline, diesel and ethanol‑blended fuels. It […]

Aiyuan HDPE‑EVOH double‑wall composite pipe adopts advanced multi‑layer co‑extrusion forming technology, specially developed for underground fuel transmission systems of gas stations. This piping solution integrates structural HDPE layers, high‑performance EVOH barrier layers and adhesive tie layers into one integral structure, solving the long‑standing pain points of fuel permeation, soil pollution and pipeline corrosion for traditional

Buried thermoplastic HDPE composite piping system is constructed via multi‑layer co‑extrusion technology, specifically engineered for underground fuel conveyance at gas stations. The pipe wall consists of functional structural layers, combining high‑density polyethylene substrate, adhesive tie‑layers and barrier functional layers. As thermoplastic materials, HDPE‑based composites retain stable ductility under varied underground temperature conditions, avoiding brittle fracture
