Stainless Welded Pipe

Stainless steel welded pipe, referred to as welded pipe, is a steel pipe made of commonly used steel or steel strip after being crimped and formed by a machine set and a mold. The production process of welded steel pipe is simple, the production efficiency is high, there are many varieties and specifications, and the equipment investment is small, but the general strength is lower than that of seamless steel pipe.

Materials:   TP304, TP304L, TP321,TP316L, 316Ti, TP310S,TP317,TP904L etc.
Standard: ASTM A312, A213, A269, DIN10217, GOST JIS (G3463, G3459)..

Stainless welded pipe package and storage

Safe and Seaworthy packing suitable for export; As per customer’s requirement.

Stainless welded pipe quality inspection:

  1. Our factory has its own “experimental testing center”.CNAS Laboratory Accreditation Certificate
  2. Control quality strictly.The first pass is the quality inspection on the production line,The second pass is full inspection of the  production quality .
  3. We have got internationally recognized certificates, ISO, CE, LR,Philippine certificate,also support third-party testing,as SGS, BV, ect.

Stainless steel welded pipe feature

Stainless steel welded pipe is continuously produced online. Generally, the welded steel pipe has high precision, uniform wall thickness, and high brightness inside and outside the pipe (the steel pipe is determined by the surface grade of the steel plate).  can be arbitrarily fixed. Therefore, it demonstrates its economy and aesthetics in high-precision, medium- and low-pressure fluid applications.
