Soft Iron RTJ Gasket

A Soft Iron RTJ Gasket is a precision machined metallic sealing ring that is used in high-pressure and high-temperature flange connections. The gasket seals by wedging action, between the gasket and its flange grooves. As the bolt load is applied, the gasket material will deform and flow into the micro-fine irregularities present in the harder flange material, resulting in a strong, metal-to-metal seal.

Soft iron is the ideal material for these gaskets. With a low hardness (approximately 90 HB), it is softer than the steel flanges it mates with. This ensures the gasket deforms without damaging the more expensive flange, making it an ideal sacrificial sealing component. Soft iron is an inexpensive option and provides excellent sealing capabilities in numerous industrial environments.

We manufacture and stock a wide variety of Soft Iron Ring Type Joint Gaskets to suit all your project requirements, all available for quick delivery.

• Soft Iron Oval Ring Joint Gaskets: Our Oval gaskets are the original design for RTJ flanges. These gaskets are highly effective in sealing flat-bottomed grooves and are frequently used in older flanged connections. Their rounded profile ensures a solid initial contact seal.
• Soft Iron Octagonal Ring Joint Gaskets: The Octagonal design is a modern and more efficient alternative. It provides a superior sealing efficiency compared to the oval type, as its straight-sided profile offers a larger contact area with the flange grooves. This design is widely used in new and high-pressure flange installations.
• Soft Iron RX-Type RTJ Gaskets: These gaskets are specifically designed for higher pressures and can be used in the same flange grooves as standard R-type gaskets. The RX design utilizes a pressure-energized seal, where the internal fluid pressure enhances the sealing performance. This makes it ideal for use in API 6A flanges.
• Soft Iron BX-Type RTJ Gaskets: The Soft Iron BX-RTJ Gaskets are designed for use with API 6A flanges at extremely high pressures (up to 20,000 psi). This gasket relies on the effect of pressure, making it the most reliable choice for critical applications where a full-face seal is required.

What is the hardness of a Soft Iron RTJ Gasket?

Soft iron is typically rated at approximately 90 HB (Brinell Hardness), making it softer than the flanges it is intended to seal.

What is the primary difference between Oval and Octagonal RTJ Gaskets?

Oval gaskets are an older design for flat-bottomed grooves. Octagonal gaskets, a newer design, provide a more efficient line contact seal and are preferred for most modern flange applications.

Are Soft Iron RTJ Gaskets reusable?

No, Soft Iron RTJ Gaskets are designed to deform and create a seal when compressed. Once a gasket has been used, it should always be replaced to ensure a safe, leak-proof connection.
