Honesty Steel & Alloys Ltd. is a manufacturer, exporter and supplier of Monel K500 Flanges, manufactured from Monel Alloy K500 / UNS N05500 / Werkstoff No. 2.4375 nickel-copper alloy. Monel K500 is an age-hardenable nickel-copper alloy developed to provide substantially higher strength and hardness than Monel 400 while retaining excellent resistance to many marine and corrosive environments.
Monel K500 contains nickel and copper as its primary alloying elements, with controlled additions of aluminium and titanium that enable precipitation hardening. The alloy is particularly valued where a combination of high mechanical strength, corrosion resistance, seawater resistance and resistance to high-velocity marine environments is required.
Monel K500 Weld Neck Flanges feature a tapered hub designed to provide a gradual transition between the flange and pipe. They are generally selected for demanding piping systems where high structural integrity and resistance to cyclic loading are important. They are available with Raised Face (WNRF), Flat Face (WNFF) and Ring Type Joint (WNRTJ) configurations according to project requirements. Monel K500 Slip-On Flanges are installed by fitting the flange over the pipe and welding around the joint. They provide a practical flange connection for various piping and equipment applications. Slip-On Flanges can be supplied in RF, FF and other configurations according to the applicable standard.
Monel K500 Socket Weld Flanges are commonly used for smaller-diameter piping and instrumentation connections. The pipe is inserted into the socket and externally welded.
Monel K500 RTJ Flanges are precision-machined with a ring groove and are used for high-integrity bolted connections. They are commonly selected for demanding pressure applications, including certain offshore and oilfield systems.
Monel K500 Threaded Flanges feature an internal thread and can be installed without welding. They are suitable for applications where welding is undesirable or impractical, subject to pressure, temperature and service requirements.
