Wall thickness control of SSAW steel pipe

Spiral Submerged- Arc Welded Steel Pipe (SSAW steel pipe) is used for low pressure liquid delivery, such as water, gas, and oil; construction and piling. And there is a long mark in it so that we should pay high attention to the wall thickness control during the whole production process.

First of all, pipe heating would be discussed here. Different types and different standard for the steel pipe would have various heating requirements. For SSAW steel pipe, heating to the average is just in order to prevent rapid up and down temperature so that to get the high quality pipes.

Secondly, original material choosing. We should figure out that average wall thickness of thick wall pipe and solid billet make the probability of mandrel bending deformation significantly reduced, can effectively improve the wall thickness of the precision. So does for the SSAW steel pipe even there is a crack treatment.

What's more, the perfect production process would another important factor for high quality of SSAW steel pipe.
