SSAW Pipe

The strength of SSAW pipe is higher than LSAW pipe, which can produce welded pipes with larger diameters from narrower billets, also it can use billets of the same width to produce welded pipes with different diameters. However, compared with the same length of LSAW pipe, the seam length of the SSAW pipe is increased by 30~100%, so the produce speed is low. Therefore, most of the welded pipes with smaller diameters use straight seam welding, and most of the welded pipes with large diameters use spiral welding.



SSAW pipe is divided into two types: automatic submerged arc welded steel pipe and high frequency welded steel pipe.

1. Spiral seam automatic submerged arc welded steel pipes are divided into two categories: A-type pipes and B-type pipes according to the pressure of the conveying medium. Type A pipes are welded with ordinary carbon steel Q235, Q235F and ordinary low-alloy structural steel 16Mn. Type B pipes are welded with steel Q235, Q235F, Q195, etc., and are used as low-pressure fluid conveying pipes.


2. There is no unified product standard for spiral seam high-frequency welded steel pipe, generally made of ordinary carbon steel Q235, Q235F etc..


Changsha Xiangjia Metal Materical Co., Ltd. is professional manufacture in SSAW steel pipe with various grades and sizes. Years of production experience and manufacturing facilities who have a capacity of 200,000 tons per annual will ensure the good quality and competitive duration of our products.
