We manufacture Stainless Steel EFW Pipes & Tubes used in the oil, shipbuilding, power plants & natural gas industries. The SS EFW (electric-fusion-welded ) austenitic chromium-nickel stainless steel pipe/tube are suitable for corrosive or high-temperature use and for general applications. These products are tested on several chemicals, physical and hydrostatic tests. It makes these to reflect paramount quality standards to maintain quality standards. As per ASTM A 358, these pipes are categorised as Class – 1, 2, 3, 4 & 5.
Features of SS EFW Pipes & Tubes
