What Should I Consider When Choosing Seamless or Welded Pipe?
Not only size is key, there are a large number of facts that should be taken into account when selecting seamless or welded pipes. Production process Depending on the diameter or the ratio of diameter to wall thickness, different procedures are used for the production of seamless pipes. The usual raw material is a pre-heated circular shaft section in a rotary furnace or, for larger diameters, a pre-formed hollow section in a piercing machine followed by pre-rolling in a rotary rolling mill. In the manufacture of LSAW pipes, individual steel plates or coils are used as the raw material. The pipes are produced in a series of different, sequential process stages, including cold forming, welding, heat treatment, calibration and non-destructive testing. Sizing Manufacturers of both welded and seamless pipes offer a wide range of standard sizes for different industrial sectors. For the individual production of welded pipes, it is possible to order and use raw materials in exact thicknesses
