Spiral submerged arc welded steel pipe generally refers to the industrial steel pipe, also known as spiral steel pipe or spiral welded pipe. Spiral pipe is to roll strip steel coil into pipe billet according to a certain spiral Angle (called forming Angle), and then weld the pipe seam, and its specification is expressed by outer diameter * wall thickness. Common materials of spiral tubes are Q235B, 16Mn, Q345B, L245, L290, X42, X46, X60, X80, etc.

Spiral welded pipe is mainly used in petroleum, chemical industry, natural gas, heating, water supply, sewage treatment, piling, dredging, bridge, steel structure, military industry, shipbuilding, pharmaceutical, papermaking, water supply and drainage, hydropower station, and other pipeline engineering fields.

General customers choose spiral tubes to see only the surface and follow the design requirements with what material, production process, and so on are unknown, judging its quality from the shape has become a crucial point. High-quality spiral welded tubes do not allow surface cracks, scarring, and folding.

Judging the quality of spiral welded pipe from the appearance of the first from the outer diameter of steel pipe, wall thickness, ellipticity, pipe end perpendicularity, and check whether there is a wrong edge, weld, and other aspects. The general spiral welded pipe unit adopts the online continuous inspection method to ensure the welding quality of the weld, which is another important feature of spiral pipe production different from straight seam welded pipe production. Continuous inspection is beneficial to the monitoring of welding defects, the stability of welding quality, and the assurance of welding grade. Selection of high-quality spiral pipe to increase the safety of construction, understanding from the appearance of the quality of knowledge, convenient for users to choose.
