ASTM B366 Monel 400 butt weld fittings stud ends
ASTM B366 Monel 400 butt weld fittings stud ends
ASTM B366 Monel 400 butt weld fittings with stud ends utilize a high-strength nickel-copper alloy combined with a specific joint type that serves as a connection point to other components, achieving a flush connection without external threads. These fittings offer excellent corrosion resistance in harsh environments such as seawater, acids, and alkalis, and can be hardened by cold working.

Material Properties (Monel 400 - ASTM B366)
Composition: Nickel-copper alloy with high strength, toughness, and good weldability.
Corrosion Resistance: Excellent resistance to seawater, steam, and various acids and bases.
Hardenability: Cold work hardens to increase strength and stiffness.
Applications: Suitable for chemical processing, offshore, and oil and gas industries.
Fitting Types (Butt-Weld and Stud-End)
Butt-Weld: These fittings are designed to be welded directly to the end of a pipe, creating a permanent, secure connection.
Stud-End: A stud-end is a type of fitting whose end is designed to accept a stud, creating a flush connection without external threads. This differs from threaded fittings, which have external threads for connection to pipe.
Manufacture: These fittings are factory-made in accordance with ASTM B366.
