Stainless Steel ERW pipes are resistant to atmospheric corrosion, sterilizing solutions, various organic chemicals, and a wide range of inorganic chemicals. Stainless Steel 321 Welded Pipes is a common austenitic 18/8 stainless steel alloy. The addition of titanium makes it a good choice for high pressure conditions below 900 degrees Celsius.

Preston Pipes and Alloys is involved in the manufacturing of 321-grade pipes and tubes of different types across India. They are, SS 321 Welded pipes/ tubes, SS 321 ERW Pipes/Tubes, and SS 321 EFW pipes/tubes. SS 321H is a high carbon version of the 321 grade which offers a higher temperature strength. The SS 321 Welded Pipes and Stainless Steel 321 Welded Tubes display good welding and forming properties. Owing to this property, they are used widely in temperatures ranging from greater than 500 degrees C.

Our SS 321 EFW pipes are mainly used in the production of pressure vessels, heat exchangers, pharmaceutical and chemical processing equipment in Gujarat, India.
