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,
