There are a number of processes about erw pipes

  There are a number of processes that may be used to produce ERW pipes. Each of these processes leads to coalescence or merging of steel components into pipes. Electric current is passed through the surfaces that have to be welded together; as the components being welded together resist the electric current, heat is generated which forms the weld. Pools of molten metal are formed where the two surfaces are being connected as strong electric current is passed through the metal; these pools of molten metal form the weld that binds the two connected components.

  We have a staff of 298,including 80 professional technicians,and our company covers an area of 160,000 square meters.In order to provide high quality,economically priced industrial seamless steel pipe and spiral steel pipe,we have purchased testing equipment which is used for chemical analysis,water pressure testing,X-ray inspection,ultrasonic testing,eddy current inspection,tension testing,chemicaltesting,etc.We are also ISO9001:2000 approved.
