Nickel Alloy Butt Weld Pipe Fittings


These nickel alloy Butt weld pipe fittings are used extensively in applications where heat resistance and/or corrosion resistance is required. Nickel Alloy Butt weld pipe fittings in this class are designed to resist failure from both of these mechanisms. Nickel alloy Butt weld pipe fittings are not suitable for high temperature sulphur rich environments.This nickel alloy Butt weld pipe fittings are frequently sold under trade name specifications but most are listed in the Unified Numbering System. Common trade names are HASTELLOY, INCOLOY, INCONEL, NICROFER, NICROM and NIMONIC.
Nickel alloys Butt weld pipe fittings have higher strength and longer life at elevated temperature than most alloys. The designer however, must determine the expected life of each component and use the appropriate creep and rupture strength in the design before selecting Butt weld pipe fittings .
