SSAW Steel Pipe, say Spiral submerge arc Welded Pipe.
SSAW steel pipe refers to use submerged arc welding technology, welded with spiral seam which can use narrow steel plate to fabricate larger diameter welded pipe. it is low production cost, simple process, easy to product large diameter pipe. So most large diameter pipe adopts SSAW process.
