Longitudinal welded pipes with high strength are suitable for construction, fluid transportation and machinery manufacturing
Our longitudinal welded pipes are made of high-quality carbon steel and are processed by high-frequency electric resistance welding (ERW) or submerged arc welding (LSAW) to ensure high weld strength and good sealing. The products have the following advantages:
✅ High strength: suitable for load-bearing structures and high-pressure fluid transportation.
✅ Diverse specifications: The outer diameter ranges from 21.3mm to 1422mm, and the wall thickness ranges from 1.7mm to 50mm to meet different needs.
✅ Economical: Compared with seamless steel pipes, it has lower cost and is suitable for large-scale projects.
✅ Widely used: suitable for building frames, oil and gas transportation, water conservancy projects, machinery manufacturing and other fields.
✅ Customized service: Supports customized length, wall thickness and surface treatment (such as galvanizing, spraying) on demand.
