RTJ Ring Type Joint Gasket

High-Pressure Metal Sealing Solution for Oil & Gas Applications

What Is an RTJ Gasket?

An RTJ (Ring Type Joint) gasket is a precision-machined metal sealing ring designed for high-pressure, high-temperature, and critical service applications. RTJ gaskets are widely used in Oil & Gas, Petrochemical, Refinery, Offshore, Power Generation, and Steam systems, where leakage is unacceptable.

RTJ gaskets seal by metal-to-metal contact between the gasket and the specially machined groove in the flange face, creating a high-integrity, pressure-energized seal.

Key Advantages of RTJ Gaskets

• Excellent sealing performance under extreme pressure and temperature

• Suitable for high-pressure ANSI / ASME Class 300 to 2500

• Resistant to blowout and vibration

• Ideal for critical and hazardous media such as steam, hydrocarbons, gas, and corrosive fluids

• Long service life with proper material selection

RTJ Gasket Types

1. Oval Ring Type Joint Gasket

• Traditional and widely used design

• Suitable for older flange designs

• Interchangeable with octagonal grooves in some cases

2. Octagonal Ring Type Joint Gasket

• Improved sealing efficiency over oval type

• Preferred in new installations

• Larger contact area with groove

3. RX Ring Type Joint Gasket

• Pressure-energized design

• Provides enhanced sealing as system pressure increases

• Fully interchangeable with R-type grooves

4. BX Ring Type Joint Gasket

• Designed for very high-pressure applications

• Commonly used in API 6A wellhead and subsea equipment

• Not interchangeable with R or RX types

Standards and Specifications

RTJ gaskets are manufactured in strict accordance with international standards:

• ASME B16.20 – Metallic Gaskets

• ASME B16.5 – Pipe Flanges and Flanged Fittings

• API 6A – Wellhead and Christmas Tree Equipment

Available pressure classes include:

• ANSI / ASME Class 150 – 2500

• API pressure ratings for oilfield equipment

Materials Available

To ensure compatibility with different media and operating conditions, RTJ gaskets can be supplied in various materials:

• Carbon Steel

• Soft Iron

• Low Alloy Steel (F5, F9, F11, F22)

• Stainless Steel (304, 316, 316L)

• Duplex & Super Duplex Stainless Steel

• Nickel Alloys (Inconel, Monel, Hastelloy)

Material hardness is carefully controlled to ensure proper deformation without damaging the flange groove.

Typical Applications

RTJ gaskets are extensively used in:

• Oil & Gas pipelines

• Refineries and petrochemical plants

• Offshore platforms

• Heat exchangers

• Pressure vessels

• Steam and high-temperature services

• Wellhead and subsea equipment
