Monel 400 Flanges And ASTM B564 UNS N04400 Slip On/ Blind/ WNRF Flange

To connet the pipe Monel 400 Flanges perform excellently due to high corrosion resistance against acidic and alkaline environments. Heat treatments of Monel Flanges is an important process to change the properties to fit certain situations. Monel 400 forged flanges are workable to connect piping under extremely corrosive environments in chemical, power, and petrochemical industries. Monel Blind Flanges are high performing and very costly compare to stainless steel flanges.

Monel 400 Pipe Flanges Face Types and uses

There are six types of Monel 400 flange faces

Ring joint flange- A RTJ flange helps in creating a metal-to-metal seal between different mating flanges. They are used in high-pressure and temperature systems.
Flat face flange- FF flanges are used in low-pressure systems as the contact surface has the same height as the bolting line.
Lap joint flange- This flange has a flat face which is not used to seal the joint. It is utilized to simply host the back of a stub end.
Raised face flange- A RF flange has a protruding hub, which allows it to seal the gaskets by concentrating pressure on the mating flanges to create a strong seal.
Male and female flange- These two flanges are similar to the tongue and groove flanges. Here the male face is ¼ high while the female face is 3/16th deep.
Tongue and groove flanges- Both these flanges fit in each other and effectively seal the flange.
