Underground Composite Pipes for Gas Stations

Multi‑layer co‑extruded HDPE‑EVOH composite pipe is engineered for underground fuel conveyance systems of gas stations, manufactured by integrated multi‑layer co‑extrusion molding process. The structure combines high‑density polyethylene substrate and EVOH barrier layer, forming a compact molecular bond between each material layer without delamination risk during long‑term service. The embedded EVOH barrier layer offers outstanding resistance […]

Anti‑static HDPE‑EVOH double containment pipe is specially developed for underground fuel pipeline systems of gas stations. It adopts a dual‑layer pipe‑within‑pipe structure, with the inner pipe serving as the primary conveying layer for gasoline, diesel and ethanol‑mixed fuels, and the outer pipe acting as secondary containment barrier. The interlayer cavity is reserved for interstitial leakage

HDPE‑EVOH double‑wall composite pipe is purpose‑built for buried fuel transmission systems at gas stations, adopting pipe‑within‑pipe secondary containment structure with integrated EVOH barrier layer. The inner primary pipe undertakes fuel transportation, while the outer secondary pipe delivers redundant containment protection. The interlayer space supports leak monitoring function. Once the inner pipe suffers accidental damage, the

HDPE‑EVOH double‑layer composite pipe is a high‑performance thermoplastic piping solution specially engineered for underground fuel transmission at gas stations. Manufactured by multi‑layer co‑extrusion technology, the pipe adopts HDPE as inner and outer structural layers while embedding EVOH as the core hydrocarbon‑resistant barrier layer. It is supplied in coil and straight‑pipe forms with multiple caliber options,
