Monel 400 Pipe Fittings are used in marine engineering and hydrocarbon processing systems where service conditions involve reducing environments. These fittings are supplied in various cut lengths and can be machined to suit specific piping requirements. The material is a copper-nickel alloy containing nickel, copper, iron, and manganese, offering good mechanical strength and resistance to corrosion in both acidic and alkaline media. Products are available in seamless and welded forms depending on application needs.

Monel 400 Pipes and Pipe Fittings (buttwelded) are manufactured in accordance with ASTM B366 and are available in dimensions as per ANSI B16.11, DIN, and EN standards. Forged fittings are specified under ASTM B164 and conform to ANSI B16.5, DIN, and EN requirements. The material provides good weldability and resistance to chloride stress corrosion cracking, as well as to sulfuric and hydrofluoric acids under controlled conditions.

These fittings are used in applications such as valves, oil refineries, and process piping systems. Bending radii can be supplied in 1D, 2D, 3D, 5D, 6D, 8D, and 10D configurations. Grades include Alloy 400 / Monel 400 (UNS N04400) and Alloy K-500 (UNS N05500). The buttweld Monel 400 Pipe Fittings are supplied in seamless or welded types and may be subjected to radiographic testing as required. High-pressure forged fittings are available in threaded or socket weld configurations.
