Ninthore Overseas is one of the Leading Manufacturer And Exporter Of High Quality Monel Alloy K500 Pipes, where we offer these products to our esteemed customers in various designs. Monel K500 Seamless Pipes is often used in pump components, doctor blades and scrapers, oil well drill collars and cable wrap, marine instruments, electronic components, springs, valve tray, and submarine parts. Monel K500 Welded Pipes is a precipitation – harden able nickel – copper alloy that combines high strength, corrosion resistance and non – magnetic properties. Monel K500 EFW Pipes combines the excellent corrosion resistance characteristic of Monel 400 EFW Pipes with the added advantages of greater strength and hardness.

Meanwhile, these Monel K500 ERW Pipes are also being offered in different sizes and shapes to our customers. Monel K500 Round Pipes (UNS N05500) is virtually nonmagnetic, even at quite low temperatures. Monel K500 Pipes can easily be welded by gas – tungsten arc, gas metal arc or shielded metal arc processes using appropriate filler metals. The nickel and copper contents of the Monel K500 Pipes were in the approximate ratio which is now formally specified for the alloy.

Monel K500 Pipes is a precipitation – harden able nickel – copper alloy that combines high strength, corrosion resistance and non-magnetic properties. There is no need for post weld heat treatment in these Monel K500 Pipes, however, thorough cleaning after welding is critical for optimum corrosion resistance, otherwise there is the risk of contamination and embrittlement.
