STEEL PIPE (Spiral Submerged Arc Welding)

Spiral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral.

Usage: Used for low pressure liquid delivery, such as water, gas, and oil; construction and piling.
