    Uncoiling
    The slitted coil is uncoiled at the entry of ERW mill and the ends are sheared and welded one after another. This results in a single endless strip. Forming
    The slitted coils are initially formed into U shape and after that into a cylindrical shape with open edges utilizing a series of forming rolls. Welding
    Welding In this stage, the open edges are heated to the forging temperature through high-frequency, low-voltage, high current and press welded by forge rolls making perfect and strong but weld without filler materials. Sizing
    After water quenching, slight reduction is applied to pipes with sizing rolls. This results in producing desired accurate outside diameter. Cutting
    In cutting stage, the pipes are cut to required lengths by flying cut off disc/saw cutter. Bevelling
    This is usually stage, where the pipes ends are faced and bevelled by the end facer. All these processes are continuous with automatic arrangements. These plain ended tubes further go for processing as per the customer requirements such as galvanizing, threading, black varnishing and more. Available Quality Standards
