American standard for SSAW steel pipe
SSAW steel pipes are produced by rolling low-carbon or low-alloy structural steel strips into pipe blanks at a specific spiral angle, known as the forming angle, and then welding the seams. This method allows the creation of large-diameter steel pipes from narrower strips of steel. The specifications of SSAW pipes are expressed as outer diameter * wall thickness. The welded pipe must pass hydraulic pressure tests, tensile strength tests, and cold bending performance tests to ensure compliance with regulations.
