High frequency straight seam welded steel pipe also know as straight seam resistance welding pipe. The outside diameter is small, usually is under DN 600. For the outside diameter is larger than DN 600, the production process will use double sided submerged arc welding process. The high frequency straight seam welded steel pipe is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agriculture irrigation and urban construction. For the transportation of liquids, the pipe can be applied for water supply, drainage. For gas transportation, the pipe can be used for transmission gas, steam, liquefied petroleum gas. For structural purposes, the pipe can be used as piling pipe fro bridges, piers, roads, buildings and other structures.


The characteristics for high frequency straight seam welded steel pipe is below:

1.  the welding speed is large.

2. the welding area is small.

3. clean up is not necessary after welding

4. the welding process can produce thin walled tube, and also metal pipe.


The high frequency straight seam welded steel pipe process is below:

Slitting---Uncoiling---Strips Leveling---Head and Tail Cutting---Strips Welding---Looper Accumulator---Forming---Welding---Burr Removing---Sizing---Testing---Cutting---Inspection---Straightening---Processing---Hydrostatic Test---Flow Detection---Coating and Marking---Finished.
