    Standards
    GB/T3091-2008, ASTM A53, ASTM A795: Welded steel pipes for low pressure fluid conveyance

    Application
    The hot dip galvanized steel pipes from Jinghua are mainly used for transport fuel gas and other fluids of general pressure.

    Steel Grades
    S235, S355, SS400, SM490

    Pipe Performance
    1. The hot dip galvanized pipe for gas transportation is made from premium quality strip steels that are sheared longitudinally;
    2. The average gram weight of zinc coating is more than or equal to 500g/m2.
    3. Before delivery, the steel gas pipes will go through 100% leakage test, 100% mechanical and chemical test, 100% technological property test and 100% UT test.
