Inconel 625 Pipe Suppliers

Inconel 625 Pipe made by a nickel-chromium-molybdenum alloy with an addition of niobium. Inconel Alloy 625 Pipe has high strength and toughness from cryogenic temperatures to 1800 F. Inconel 625 Seamless Pipe also have some excellent characterstics like good oxidation resistance, exceptional fatigue strength, and good resistance to many corrosives.Alloy 625 Pipe stock size range is OD.12" – 4"and schedule Sch10 through Sch80. Inconel 625 Welded pipe is readily welded by GMAW (MIG), GTAW (TIG), SMAW (manual) and SAW processes.Sch40 Inconel 625 Pipe is a favorable choice for sea water applications and is highly resistant in a wide range of organic and mineral acids. Inconel Alloy 625 Seamless Pipe is a corrosion and oxidation resistant nickel alloy that is used both for its high strength and outstanding aqueous corrosion resistance. Inconel 625 Round Pipes also being offered in different sizes and shapes to our customers. Some sizes and compositions that are standardized (e.g. by ASTM, AMS and BS) are already in stock in our storages around the world. Inconel 625 Clad Pipes are widely used in various applications industry like oil and gas, petrochemical, medicine, food, paper, machinery, natural gas etc.
