Monel 400 Pipe Fittings
Monel 400 Pipe Fittings are high-performance nickel-copper alloy components widely used in demanding industrial applications. Manufactured by Rose Metal Industries, these fittings are stocked and exported to various regions including Tamilnadu, Andhra Pradesh, Karnataka, Telangana, Puducherry (Pondicherry), and Andaman & Nicobar Islands. Known for their outstanding corrosion resistance and mechanical strength, Monel 400 fittings are ideal for marine, chemical, and offshore environments where exposure to seawater and aggressive chemicals is common...
The chemical composition of Monel 400 Pipe Fittings typically consists of 63–70% nickel, 28–34% copper, with small amounts of iron, manganese, carbon, and silicon. This unique alloy combination provides exceptional resistance to chloride-induced stress corrosion cracking and excellent performance in acidic or alkaline environments. This makes Monel 400 fittings highly suitable for piping systems in desalination plants, chemical processing units, offshore platforms, and marine vessels.
From a mechanical standpoint, Monel 400 Pipe Fittings exhibit tensile strength ranging from 550 to 690 MPa, a yield strength above 220 MPa, and elongation between 30–45%. These properties ensure that the fittings maintain structural integrity under high pressure and temperature conditions. Hardness values typically range between HRB 70–95, depending on the heat treatment and product form. This combination of strength and ductility allows the fittings to withstand mechanical stresses while retaining corrosion resistance..
Rose Metal Industries manufactures Monel 400 Pipe Fittings in a wide range of sizes and dimensions, including elbows, tees, reducers, couplings, and flanges. Standard nominal sizes range from 15 mm (1/2") to 200 mm (8") with wall thicknesses from 1.65 mm to 12.7 mm and various schedules including 10, 40, 80, and 160. Custom sizes and dimensions are also available to meet specific project or engineering requirements, ensuring seamless integration into existing piping systems.
