    Add Service

    Adhering to the corporate attitude of being responsible for customers, employees, society, and the environment, Shanghai Huifei Scientific Planning has organized the construction of an SCM technical service department and innovatively designed and produced an STC circulation tank (200KG/50KG) odorless filling as a value-added service for THT sales.

    Principle DescriptionAdvantages of STC (Circulation Tank) FillingApplicable Conditions
    Quick connectors are used for each connection part, and the entire process is closed.
    The power source provided for refueling is nitrogen gas, which does not require AC power and is safe and reliable.
    The STC tank is a standard 1-ton pressure tank, and customers can choose the amount of filling at their discretion. (If 3 tons need to be filled, transport 3 STC tanks to the gate station).
    Recycling tank filling, customers can choose 200KG/50KG at their own discretion, and our company can provide training on the filling process.

    Can Washing Service

    After long-term use of the tetrahydrothiophene storage tank at the gas gate station, the odorization pump may repeatedly pump for a long time or rainwater may seep into it, causing residual waste or tetrahydrothiophene phase change (milky white coagulation viscous) to adhere to the inner wall (or bottom) of the storage tank.

    The odorizing pump must be adjusted to its maximum power in order to add tetrahydrothiophene to the gas medium pressure pipeline network, which can even cause pipeline blockage. For this purpose, our professional technical team can provide customers with on-site cleaning of odorant storage tanks and thoroughly clean the odorization system.
