SPIRAL WELDED STEEL PIPES

Spiral-welded steel pipes are made by winding flat sheets of steel into long pipes.  The sheets are welded together on both the inside and outside of the pipe using a process called submerged arc welding.
Spiral-welded steel pipes are used to conduct water, sewage, petrol, natural gas and other related similar substances; they are also used as piles in the construction of buildings and advertising billboards, where their heavy metal can support great weights.
