Spiral Welded Pipe

Spiral welded pipes are made of steel coil sheet. The coil is unwounded and welded while it is being turned into the shape of spiral welded pipe.

Steel Pipe Manufacture

Seamless steel tube often could be formed and produced through hot rolled craft and cold drawn technology. Certainly the strength of hot rolled seamless steel pipes rather than cold drawn seamless steel tubes. About its common use respectively are
* Steam pipeline,
* Gas pipeline,
* Liquefied gas pipeline,
* Natural gas pipelines,
* All kinds of pipelines for petroleum products,
* Pipelines for conveying various other gases or liquids.
