Submerged arc welded straight seam steel pipe

Description: The welding process used for submerged arc welded straight seam steel pipes is submerged arc welding technology, which uses filler welding and particle protection flux for submerged arc welding. The diameter produced can reach 1500mm. Submerged arc welded straight seam steel pipes are widely used in steel structures, pile driving, fluid transportation, long-distance pipelines, and other places.

The production processes of submerged arc welded straight seam steel pipes include JCOE forming technology and coil forming submerged arc welding technology. When the diameter is large, two steel plates may be used for rolling, which can form a phenomenon of double welds.

The standard GB/T3091-2008 for the production of low-pressure fluid steel pipes, GB/T9711.1-2-1997 for the production and use of petroleum gas steel pipes, and API5L pipeline steel pipes can also be executed.

Production material of submerged arc welded straight seam steel pipe: Q19-Q345E; 245R; Q345QA-D; L245-L485; X42-X70.
