Submerged Arc Welded Spiral steel Pipe SSAW


The spiral submerged arc welded pipe is made of hot-rolled steel strip through constant temperature spiral forming and automatic submerged arc welding. The manufacturing process is to roll the steel strip, make the rolling direction at a certain angle to the center direction of the tube, and then form and weld, so the weld is spiral.

Submerged arc welding is an important welding method. Its inherent advantages include stable welding quality, high welding productivity, no arc light and little smoke, making it an ideal choice  in the production of important steel structures such as pressure vessels, pipe section manufacturing, box beam and column manufacturing. The strength of SSAW spiral welded pipes is generally higher than that of straight seam welded pipes. Welded pipes with larger diameters can be produced from narrower billets, and welded pipes with different diameters can also be produced from billets of the same width.

Product features
① High quality material
The qroducts are made of high-quality materials with guaranteed quality and firm and reliable quality
②What is spiral welded pipe?
Spiral pipe, also known as spiral steel pipe or spiral welded pipe. is a low carbon structural steel or low alloy structural steestrip accorcing to a certain helix angle (called forming angle) rolled into a tube, and then welded joints made of, It can be produced with a narrow strip of large diameter steel pipe.
③What is the advantage of spiral welded pipe?
Straight seam welded pipe production process is simple. high production effciency, low cost. rapid develop- ment. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the pipe with larger diameter can be produced with the narrow billet. The pipe with different diameter can also be pro- duced with the same width.
Spiral steel pipe is made by steel coil, extrusion forming under the normal temperature, then taken the technology of double wire and double-faced submerged-arc welded. Spiral steel pipe, also known as spiral or helix spiral steel pipe, is a low-carbon steel or low-alloy structural steel strip at a certain helix angle (called molding angle) rolled into a tube, and the tube is made of welded joints It can be produced with a narrow strip of large diameter pipe.
