Submerged arc-welded steel pipe with large mouth straight seam DM600-DN2600

Submerged arc welded steel tubes and their standard classification: Spiral welded steel tubes (SY5036-83) used for pressure fluid transport are mainly used for pipelines conveying oil and natural gas; Spiral welded high frequency steel tubes (SY5038-83) for confined fluid transport, welded by the high frequency lap welding method, for confined fluid transport.

The steel tube has strong bearing capacity and good plasticity, which is convenient for welding and machining. Submerged arc welded steel pipe (SY5037-83) with spiral seam for general low-pressure fluid transport, which is made by double-side automatic submerged arc welding or single-side welding for general low-pressure fluid transport such as water, gas, air and steam.
