Spiral submerged arc welded steel pipe is a kind of metal pipe with spiral seam welded by submerged arc welding technology.SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature.

The use rate of SSAW steel pipe is relatively high, and the application range is very wide. How to choose before choosing should pay attention to the quality.The first method is a more professional detection method,which is to detect by the strength of the pressure vessel.

In the production process of SSAW steel pipe, a series of matters need to be paid attention to. In addition to the following test items, in accordance with API standards and other relevant standards and special requirements of some users

Spiral submerged arc pipe (SSAW pipe) is its advancing direction and the forming angle of the center line of the formed tube. The side forming edge is welded and welded into a spiral shape.

The influence of ssaw steel pipe production process factors on the quality of single-side welding double-sided forming welds mainly includes welding current, welding speed, number of welding layers

In the production process of SSAW steel pipe, a series of matters need to be paid attention to. In addition to the following test items, in accordance with API standards and other relevant standards and special requirements of some users

Because ssaw steel pipe can be made by a coil width continuous forming welding production, easy automation, and using double-sided automatic submerged arc welding type, there are a variety of testing method to check weld quality assurance checks.

Jiangsu Shunli Steel Group has 3 large-scale spiral submerged arc welded pipe production lines, which can produce steel pipes with diameters of Φ219～Φ3200, with an annual production capacity of 200,000 tons.
