WNRTJ Flange

• Design:The RTJ (Ring Type Joint) flange is a type of flange designed for high-pressure and high-temperature applications. It features a groove or recess into which a metal ring gasket is placed. The ring joint gasket, which has a circular cross-section, is compressed between the flanges to create a reliable, leak-tight seal.


• Applications: WNRTJ Flanges are commonly used in industries requiring high-pressure and high-temperature service, such as in oil and gas, petrochemical, chemical processing, and power generation. They are particularly useful in critical applications where standard gaskets might not provide adequate sealing performance.


• Installation: The WNRTJ Flange is installed by placing the metal ring gasket into the machined groove of the flange. When the flange is bolted to a mating flange, the gasket is compressed between the flanges to ensure a tight, secure seal.

Notes:

• Chemical Composition: Indicates the elements present in the material, such as chromium and nickel, which contribute to properties like corrosion resistance.


• Yield Strength: The stress at which the material begins to deform permanently.


• Tensile Strength: The maximum stress the material can withstand while being stretched or pulled before breaking.


• Elongation: Represents the ductility of the material, indicating how much it can stretch before breaking.
