    SSAW鋼管

    SSAW pipe full name is Spiral Submerged arc welding pipe. The pipe is formed by spiral submerged arc welding technology which is called SSAW pipe. Generally speaking, when it comes to the same standard and steel grade, the price of SSAW pipe is cheaper or lower than ERW pipe and LSAW pipe. The strength is higher than the straight seam welded pipe. SSAW/SAW STEEL PIPES Usage: Used for low pressure liquid delivery, such as water, gas, and oil. Process: SAW(SAWL,SAWH): Spiral Welded SSAW: Spiral...
