Ring Joint Gaskets “RTJ’s”

Introduction

Ring Type Joint Gaskets or “RTJ’s as they are commonly known are metallic sealing rings suitable for high temperature and pressure applications and are fitted in ring groove type flange applications. They are widely used in the oil/gas (onshore & offshore) , petrochemical industries and in valve and pipework. Choice of material may be determined to suit higher temperatures and aggressive media. They comply with ASME B16.20 standards and API 6A specification. Industrial

Gaskets only supplies Ring Type Joint Gaskets that are API approved and Certified.

Ring joint gaskets are commonly made out of the following materials:

Soft Iron / Low Carbon Steel / Stainless Steel / Monel® / Inconel® / Incoloy® / Hastelloy® / Duplex

The gasket material should be selected to suit the service conditions. It is always recommended that the gasket material be softer than the mating flanges. Each Ring Type Joint is identified by low stress stamping with style, ring number, API license number, material reference, month and year of manufacture and unique Industrial Gaskets material identification number. In accordance with API Specifications, soft iron and low carbon steel Ring Type Joints are protected with electroplated zinc to a maximum thickness of 8μm. Alternative material coatings can be supplied on request.

Cross Section / Styles

• R Oval or octagonal style of gasket
• RX Self-energizing style of gasket
• BX Used in API spec 6A flanges that have ring grooves machined into them to accept this style of gasket
• SRX Similar to the RX style gasket with special vent holes to allow water to escape in subsea applications
• SBX Similar to the BX style gasket with special vent holes to allow water to escape in subsea applications
• Combo Consists of two different sizes having the same pitch. Used where mating flanges have different groove dimensions
