Welded Process Pipes

Stainless Steel welded pipes are made using an automatic welding process with in line equipment of the highest technology in combination with quality system approved according to ISO 9001 – 2008 form the basis for our high quality. We have facility to produce filler metal during the welding process and with a single longitudinal weld.

Manufactured in accordance with international standards ASTM A312 and ANSI/ASME B36.19M 2004 in grades TP304, TP304L, TP316 and TP316L (Special Grades available upon request), these products are intended for high – temperature and general corrosive service. Produced from cold rolled stainless steel coils, they are free of scale and contaminating exogenous iron particles. Stainless steel welded pipes are used in many applications, primarily in pulp paper, chemical and petrochemical industries, pipes chemical tankers, and for handling of water / wastewater such as pipelines and desalination plants.

General Characteristics

  • Excellent corrosion resistance
