  • Production Technology Of Thermal Expansion Seamless Steel Pipe

    Production Technology Of Thermal Expansion Seamless Steel Pipe

    The thermal expansion seamless steel pipe adopts the expansion technology of the original pipe. The expansion is a pressure processing process that uses hydraulic or mechanical means to force the steel pipe to expand outward along the radial direction. The mechanical method is simpler and more ef...
