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 […]

HDPE double‑wall composite fuel pipeline adopts pipe‑in‑pipe structural design, which is widely applied to underground fuel delivery, suction and vapor transmission systems of gas stations. The inner primary pipe undertakes the transportation of gasoline, diesel and alcohol‑blended fuels, while the outer HDPE secondary containment pipe forms a protective interlayer space. If leakage occurs on the

Alkane waste gas treatment system for naphtha & jet fuel, professional producer Vohon Petrochemical Alkane‑based waste gas containing n‑hexane, naphtha and jet fuel vapors is frequently generated in petrochemical storage‑transportation, oil loading‑unloading and fine‑chemical production processes. Such waste gas covers a wide boiling‑point range of light‑heavy alkane fractions. The media are highly flammable, and oil

Ester‑based VOCs waste gas containing ethyl acetate and butyl acetate is commonly generated in pharmaceutical fine‑chemical, coating and printing production processes. Ester solvents feature high volatility and flammability. Production sites often operate with intermittent exhaust modes and fluctuating gas concentrations, while moisture and trace impurities may mix into the gas stream, bringing practical challenges for
