Spiral submerged arc welded steel pipe refers to a metal pipe with a spiral seam welded by a submerged arc welding process.

Production Process

SSAW pipe’s full name is Spiral Submerged arc welding pipe. The pipe is formed by spiral submerged arc welding technology which is called SSAW pipe.

SSAW pipe’s 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.

Characteristics of SSAW steel pipe
Spiral submerged arc (SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral, the advantage of the same specification to produce a variety of diameter sizes steel pipe, raw materials to adapt to a wider range, the weld can avoid the main stress force better, the disadvantage is the poor geometry of the weld length compared to the long straight seam pipe, prone to cracking, porosity, slag, welding partial welding defects such as welding stress was tensile stress state. General Oil and Gas Pipeline design specification spiral submerged arc can only be used for Class 3, Class 4 regional. Raw materials instead will this process improvement abroad steel plate forming and welding separate pre-weld and lean and, after welding cold flaring near UOE pipe welding quality, currently no such process of plant improvement direction. “West-East” still is a traditional craft production, just expanded diameter of the pipe end.

It is possible to produce welded pipes with large diameters with narrow blanks, and it is also possible to produce welded pipes with different pipe diameters with blanks of the same width. The production cost is low, the process is simple, and it is easy to produce large diameter pipes. Large-diameter welded pipes are mostly made by spiral submerged arc welding.
