METLINE Industries is a leading manufacturer and exporter of high nickel based special alloy buttweld pipe fittings and flanges. Stainless steel Alloy 20 pipe fittings are available in the size range of ½” NB to 8” NB. For sizes above 8”NB, we offer our customers with seam welded 100% radiography tested Alloy 20 pipe fittings. METLINE offers a complete range of Alloy 20 pipe fittings such as Alloy 20 reducer, Alloy 20 elbow, Alloy 20 tee, Alloy 20 cross, Alloy 20 stub ends and Alloy 20 pipe bends.
We specialise in the manufacture and supply of Alloy 20 pipe bends in both standard and non standard sizes, with bending radius of 1D to 10D.
Alloy 20, also commonly referred as UNS NO8020, is a high alloy special stainless steel grade with excellent resistance to sulfuric acid and chloride stress corrosion cracking. The alloy contains nickel, chromium, molybdenum and copper contents which together help in providing excellent general corrosion resistance. Because of good resistance to corrosion, crevice corrosion, and pitting, this stainless steel alloy is widely used for manufacturing tanks, heat exchangers, process piping and pickling equipment.
Alloy 20 pipe fittings, Alloy 20 flanges and other Alloy 20 grade products are used in various applications throughout the chemical process industry, pharmaceuticals, synthetic rubber, plastics, industrial heating equipment, pulp and paper manufacturing.
METLINE also stocks and supplies a complete range of stainless steel Alloy 20 pipes to complement our existing production range of buttweld fittings and flanges. Alloy 20 pipes can be supplied in cut to length sizes and also machined or fabricated to meet your piping requirements.
