Monel K500 Flanges Manufacturer, Supplier & Exporter

Solitaire Overseas is the well-known manufacturer, distributor and exporter of the Monel K500 flanges, which has a wide variety of Alloy K500 Flanges such as Monel K500 Socket Weld Flanges, Monel K500 Blind Flanges, Alloy K500 Slip On Flanges, Weld Neck, Threaded, Lap Joint and Ring Type Joint.Monel K500 Pipe Flanges are in compliance with ASTM B564 / ASME SB564 and come in UNS N05500.Although Monel K500 is corrosion resistant like Monel 400 Flanges and Monel Flanges, it is much stronger and harder when it comes to tensile strength because of the incorporation of aluminium and titanium materials.

These flanges have a virtual nonmagnetism, and are able to sustain temperatures to as low as -150degF and are suited to sour well, oil and gas, and marine applications.Alloy K500 Flanges are the best priced flanges in the market today.

Frequently Asked Questions (FAQs)

What is the difference between Monel K500 and Monel 400 Flanges?

Aluminium and titanium additions increase the tensile strength of Monel K500 by approximately two times and its yield strength by three times those of Monel 400.The two grades have similar corrosion resistance.K500 is favored in applications that have high strength, sour-gas and marine applications that need higher hardness and mechanical performance.

What standard governs Monel K500 Flanges?

Monel K500 Flanges are also produced as per ASTM B564 and ASME SB564 in UNS N05500.Dimensions are based on ANSI B16.5 and B16.47.They come in Class 150 to 2500 and pressure ratings of PN6 to PN64. DIN equivalent is Werkstoff 2.4375.

Are Monel K500 Flanges magnetic?

The Monel K500 Flanges are practically nonmagnetic and sparkless up to minus 150 degrees F.This renders them suitable in sensitive offshore, naval as well as electronic environment where magnetic properties must be minimised in matters of operation and safety.

What industries commonly use Monel K500 Pipe Flanges?

Monel K500 Pipe Flanges are common in oil and gas, marine, chemical processing, aerospace, desalination and petrochemical.They can work in sour wells, seawater systems and high-pressure environments with hydrofluoric acid and salts as well as alkaline media.

What surface treatments are applied to Alloy K500 Flanges?

The most widespread surface finishes are pickling and electropolishing.Electropolishing is done to remove the outer part to give it a smooth finish.Pickling eliminates the magnetic surface film which may be generated during the processing process, and returns the material to its nonmagnetic state to be used in the end application in critical service conditions.
