    Production equipment of lsaw steel pipe

    Plate edge milling machine
    The milling machine mills the two sides of the plate to exacting standards in order to meet width, edging and groove shape specifications.

    Edge crimping machine
    The crimping machine crimps the edges of the plate to form the required curvature.

    Tack welding machine
    The two edges of the open seam pipe are brought together by the tack welding machine. then welded by the tack welder using a metal active - gas arc welding("MAG" )process.

    Forming machine
    Utilizes the "JCO" process to bend and form the crimped steel plate into a steel pipe.

    Interior welding machine
    The interior longitudinal seam of the pipe is welded from the inside by fixing 4 welding heads while moving pipe and using submerged-arc welding process.

    End facing machine
    The machine levels the pipe end with rotating cutter heads to ensure that required groove and edge specifications are met.

    Hydrostatic tester
    Using end face sealing technology eliminates blind zones during hydrostatic testing. The tester is also equipped with automatic recording and storing functions.

    Expanding machine
    The pipe is subjected to full-length expansion to increase the precision of the pipe dimensions and to improve the internal stress distribution.
