Monel K500 Flanges Manufacturer in India
At Metinox Overseas, we manufacture and supply high-quality Monel K500 flanges at Metinox Overseas, which are used in industries that require strength, reliability, and duration of performance. We have a good reputation in providing reliable piping services in critical applications and have achieved this through a history of more than 20 years of operation, coupled with the ISO 9001:2008 certification. The Monel K500 flanges that we manufacture are made of premium-grade alloy, which is characterized by high mechanical strength, great resistance to corrosion, and resistance to hard-to-withstand environments, hence suited to the marine, chemical, and high-stress industrial environment.
Our products are Monel K500 flanges in ANSI B16.5, ASME B16.47, MSS-SP44, API, AWWA-C207, and BS standards, in all standard types such as Slip-On, Weld Neck, Blind, Threaded, Socket Weld, and Lap Joint flanges with pressure ratings of 150 Lbs through 2500 Lbs. The broad spectrum of it enables them to operate successfully in both high-pressure and low-pressure systems.
All Monel K500 flanges are manufactured subject to stringent quality inspections with modern manufacturing techniques, as well as the precise control of dimensions. We have ready stock in standard sizes and grades, which guarantees timely delivery both in India and the overseas market. Oil and gas, petrochemical, power generation, chemical, pharmaceutical, marine, offshore, water treatment, thermal systems, and heavy engineering are the products that are trusted in, but constant quality, performance, and reliability matter.

Frequently Asked Questions (FAQ)
Monel K500 flanges are pipe flanges made from a nickel-copper alloy with added elements that give them higher strength and hardness than standard Monel alloys.
They are chosen for their high strength, excellent corrosion resistance, and long service life in harsh and demanding environments.
Yes, they are highly suitable for marine use because they resist seawater corrosion, salt attack, and chloride damage.
Yes, they perform well in high-pressure and high-temperature applications, making them ideal for heavy-duty industrial systems.
Monel K500 flanges offer higher strength and hardness, while Monel 400 flanges focus more on general corrosion resistance and flexibility.
