Okoye Nickel Alloys is a reputable manufacturer and supplier of Monel K500 Tube Fittings based in Kinshasa, Congo. They’re known for delivering top-notch fittings that boast remarkable strength, corrosion resistance, and durability. Each fitting is precision-engineered to guarantee reliable performance, even in the toughest industrial, marine, and chemical settings where high mechanical performance is a must. Okoye Nickel Alloys provides a diverse selection of Monel K500 Tube Fittings, including elbows, tees, reducers, couplings, and caps, all crafted to meet international quality standards. Their products cater to various industries, such as offshore oil and gas, marine engineering, chemical processing, desalination, and power generation.
The Monel K500 Tube Fittings are primarily made from a nickel-copper alloy, typically containing 63% nickel and 28–34% copper, with small amounts of aluminum and titanium added to boost strength, hardness, and corrosion resistance. This alloy is particularly effective against seawater, hydrofluoric acid, alkalis, and other aggressive substances. With a tensile strength of around 880 MPa, a yield strength of 415 MPa, and an elongation of 25%, these fittings ensure outstanding mechanical stability. They maintain their toughness, ductility, and dimensional integrity even at high temperatures, while also resisting stress corrosion cracking and embrittlement.
