Thick-walled spiral steel pipe forming process
Preformed Spiral Steel Pipe
Spiral steel pipes are produced using an advanced double-sided submerged arc welding technique, which ensures welding at **positions without defects such as misalignment, weld offset, or incomplete penetration. This technique facilitates easy control over both the quality and positioning of the welds. The spiral steel pipes are焊接 using a specialized welding process, achieving seamless焊接 at **positions, thereby eliminating any error defects and guaranteeing the pipes' compliance and superior quality.
