UNS S30400, S31600, N08904 EFW Pipe Supplier, Stainless Steel EFW Pipes Class 1 / 2 / 3 / 4 / 5, Reliable Pipes & Tubes.
Reliable Pipes & Tubes is a leading supplier, stockholder, and exporter of high-grade UNS S30400, S31600, N08904 EFW Pipe. Electric Fusion Welded (EFW) pipes are produced through a process in which high voltage electricity is passed onto the material to heat and melt it. Our UNS S30400, S31600, N08904 EFW Pipe are designed for high-temperature and general corrosive service operations, complying with strict international standards.
The UNS S30400, S31600, N08904 EFW Pipe cover three primary grades of austenitic stainless steel. UNS S30400 (304) contains 18% chromium and 8% nickel, offering excellent general corrosion resistance. UNS S31600 (316) adds molybdenum for superior resistance to pitting and crevice corrosion in chloride environments. UNS N08904 (904L) further adds copper for outstanding resistance to reducing acids and warm seawater. These pipes are welded by rolling the plates and welding the seam and then cleaning the weld flash with scarfing blades.
We offer a comprehensive size range of UNS S30400, S31600, N08904 EFW Pipe from 1/2" NB to 100" NB in various classes and schedules to meet custom industrial applications. Every UNS S30400, S31600, N08904 EFW Pipe supplied by Reliable Pipes & Tubes undergoes transverse guided-bend weld testing, transverse tension testing, hydrostatic testing, and radiography (where required by class specifications) to ensure optimal joint efficiency and structural integrity.
