Water main pipes - SSAB - SSAB - SSAB high-strength steel

SSAB's welded steel pipes can be used in water mains, where the normal maximum operating pressure is 16 bar. Water main pipe size fittings are delivered for diameters DN 400. The long lifespan of steel water main pipe materials is ensured by an external polyethylene coating and an internal concrete or epoxy layer suitable for use with drinking water. Welding of HSLA Steels - TWISecondly, even though steels generally have very low levels of sulphur, the steels containing less than 0.05%C may suffer from solidification cracking in the root pass of butt joints, particularly if the root bead is deposited at a high welding speed. The reason for this is that high dilution of the filler metal produces a weld metal low in carbon.
