    Chemical

    Chemical pipelines are of extremely harsh working conditions. The corrosiveness will be more serious since the pressure and temperature will increase irregularly. And the working conditions will be worse, if catalysts are used in some sections. Pumped medium in chemical industry are also complex, including liquid, liquid containing solid particles, gas, powder, high viscosity fluid and so on.

    Generally speaking, valves of common materials and conventional design cannot meet the requirements of the harsh working condition in chemical industry, being prone to frequent maintenance, reduction of output and other problems.

    Material

    In view of the needs in the chemical industry, Weidouli specially designed titanium and nickel alloy valves to ensure the stability of the valves, to withstand corrosion under different working conditions, to extend the service life and to increase the productivity benefits of users. With rich customization and project experience, we can certainly give you a perfect choice!

    Project case

    The largest resorcin project in China

    • Project time: 2014-2018
    • Customer: Zhejiang Longsheng Group Co., Ltd
    • Customer requirements: dilute sulphuric acid and resorcinol at a temperature of 230℃.
    • Valves used: Control valve, Ball Valve, Check Valve and Globe Valve made of Zirconium and Nickel.
    Petro Chemical

    Petrochemical installations cover a wide range of applications, producing an array of products under an enormous variety of operating conditions. The two most common petrochemical classes are olefins like ethylene and propylene plus aromatics like benzene, toluene and xylene isomers. In addition to the safe handling of toxic products, a good corrosion resistance, reliability, and low cost are of great importance, which is specially applied for hydrogenation, dehydrogenation, MMA, alkylation etc. Units.

    Material

    Weidouli has a wide range off ball, gate, globe and check valves which are supplied to the Petrochemical market with materials variety of hastelloy, alloy 20, monel etc. Also bellow sealed gate and globe valves or pressure seal bonnet construction structures. We are aslo able to provide rapid reponses in the event of outages, thereby minimizing downtime and maximizing productivity.
