Product description
Straight seam welded steel pipes are pipes formed by bending steel strips or plates into a circular shape and then welding them, with visible seams on the surface and no additional surface treatment. Customized products are those that undergo processing such as grooving, threading, or machining after the pipes are formed, in order to meet specific usage requirements.

Structural Function
Straight seam welded steel pipes can serve as base pipes, which can be treated with various anti-corrosion coatings or galvanization to enhance corrosion resistance and extend service life.
In China, straight seam steel pipes are mainly used in water supply projects, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction. They are suitable for:Liquid transportation: water supply, drainage;Gas transportation: gas, steam, liquefied petroleum gas (LPG).
They can be used as driven pipes, bridge structures, dock supports, road construction, and building structural pipes, etc.
Value advantage
  • High-quality raw materials
    High-quality raw materials
    High-quality medium-wide steel strips are procured from large steel plate manufacturers such as Delong, Ronggang, and Ruifeng, ensuring the quality of the steel plates.
  • Advanced production equipment
    Advanced production equipment
    The pipe welding and forming process adopts the advanced F-F-X forming technology solution from Japan, which enhances the controllability of the forming system and improves the product precision. The welding process uses the solid-state high-frequency welding machine of the American company Servomech, ensuring the stability of the welding process.
  • Strict process control and management
    Strict process control and management
    For product inspection, online 100% eddy current flaw detection and hydraulic pressure testing are adopted to ensure that there is no leakage at all.
