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 […]

Ketone‑based VOCs waste gas is frequently generated in pharmaceutical fine‑chemical, resin synthesis and chemical production processes. Typical components include acetone, cyclohexanone, MBK and other ketone solvents. These ketone vapors are highly volatile and flammable. Production sites often feature intermittent exhaust and fluctuating gas concentrations, with trace moisture and impurities mixed in the gas stream, bringing

Underground fuel‑delivery pipelines form the core safety infrastructure for every petrol station. Static electricity accumulation, hydrocarbon vapor permeation and soil‑driven corrosion are three major hidden risks for traditional steel or ordinary PE piping. The VOHON conductive composite fuel pipe is purpose‑built for underground petrol‑station installation. Manufactured by multi‑layer co‑extrusion technology, it combines HDPE, EVOH barrier

Underground fuel‑transfer piping is the critical infrastructure for every gas station. Traditional steel pipelines suffer from corrosion, rust‑caused leakage, static‑charge accumulation and high vapor permeation, bringing environmental pollution and potential explosion risks. VOHON multi‑layer fuel composite pipe solves these pain points. It integrates HDPE, EVOH barrier resin, conductive masterbatch and imported adhesive, co‑extruded in one

When designing or upgrading a service station, the choice of underground fuel conveyance is critical. Traditional steel piping can face corrosion, while single-wall plastic may lack permeation resistance. Today, a modern composite pipe solution is gaining global attention for its ability to combine structural strength, chemical resistance, and leak prevention. For EPC contractors and station
