Features of submerged arc steel pipe:
Submerged arc steel pipe is a kind of ordinary straight seam steel pipe, its characteristics have been recognized by everyone, so what are its characteristics?
1. The welding process used for submerged arc steel pipe is submerged arc welding technology, which uses filler welding and particle protection flux submerged arc.
2. The production process of submerged arc steel pipe includes JCOE forming technology and rolling forming submerged arc welding technology. When the diameter is large, two steel plates may be used for rolling, which will form a phenomenon of double welds.
3. The submerged arc steel pipe can implement the standard GB/T3091-2008 low-pressure fluid steel pipe production standard, GB/T9711. 1-2-1997 petroleum gas steel pipe production and use standard, and API5L pipeline steel pipe execution standard can also be implemented.
4. Submerged arc steel pipe material is Q195A-Q345E; 245R; Q345QA-D; L245-L485; X42-X70. The pressure parameters mainly include 2ST/T, S is the yield strength, and T is the wall thickness.
5. Now submerged arc welding has been developed into double-wire submerged arc welding and multi-wire submerged arc welding, and the efficiency is further improved. It is widely used in steel structures, piling, fluid transportation, long-distance pipelines, and other places.
