Stainless Steel LSAW Pipes

Sun Mark Stainless manufactures and supplies premium stainless steel LSAW pipes, ranging from 168.28 mm to 812.80 mm in outer diameter.

What sets us apart is our advanced double-sided submerged arc welding (DSAW) process, which ensures deep, defect-free welds with exceptional structural integrity. Each SS LSAW pipe undergoes radiographic, ultrasonic, and hydrostatic testing to validate weld quality and wall thickness consistency.

Engineered for superior performance in corrosive marine environments and high-pressure pipeline networks, our SS LSAW pipes are trusted for critical applications worldwide.
