General notes.. All dimensions are in millimeters. Tolerances.. P = average pitch diameter of ring ±0.18; A = width of ring ±0.20; B and H = height of ring +1.3. -0.5 Variation in height throughout the entire circumference of any given ring shall not exceed 0.5 within these tolerances

Ring Type Joints manufactured to ASME B16.20 are permanently marked according to standard. Each Ring Type Joint manufactured to an API standard is identified by low stress stamping with style, ring number, API license number, material reference, a unique Flexitallic material identification number, and month and year of manufacture.

2022年11月5日 · A ring joint flanges (RTJ) is used when a metal-to-metal seal between the mating flanges is required (which is a condition for high-pressure and high-temperature applications, i.e. above 700/800 C°).

Style R ring type joints are designed to seal pressure up to 6,250 psi in accordance with ASME B16.5 pressure ratings and up to 5,000 psi in accordance with API 6A pressure ratings. Style R ring type joints are manufactured in both oval and octagonal configurations.

The Octagonal series of RTJ – Style R is a modified oval joint ring to provide better sealing performance. Style R gaskets are manufactured in accordance with both API 6A and ASME B16.20 size/ratings, all certified to API 6A through EN10204 Type 3.2.

The application thresholds values of oval octagonal RTJ gaskets can be more accurately calculated in relation to material, diame-ter, pressure, temperature and the surface pressure limits. Here the fictitions sealing characteristic values in accordance with AD are replaced with the values of σv and σϑ.

Metallic ring type joint gaskets are heavy duty, high-pressure gaskets largely used in offshore and onshore petrochemical applications. They are precision-engineered components designed to be used in conjunction with precision-machined flanges. All our Ring Joints are manufactured according to ASME B16.20 and API 6A.

A Ring type joint flange(RTJ) is a machined metallic ring with a deep groove cut into its face. This groove rests a metal ring which gets compressed when the connecting bolts of the flange are tightened.
