Ring type joints are precision machined metallic gaskets generally used in high pressure applications such as the Oil, Gas, Petrochemical and Offshore industries. 
These joints are designed to concentrate the bolt load over a small area thus producing high sealing stresses.  As the Ring Type Joint Material should always be softer than the mating flanges, the high seating stress causes ”plastic flow” of the ring joint in the flange faces creating the seal.

Rilson supply Ring Type Joints which are fully approved to API 6A Product Specification level 4, which is the highest quality rating as well as ISO 9001:2000.

 RTJ PROFILES Oval and Octagonal section Ring type Joints are designed for flanges with standard ring type grooves.  These standard shapes are used to seal pressures up to 5,000 psi in accordance with API 6A.  
The Octagonal cross section has a higher sealing efficiency than the Oval cross section and is therefore preferred. The oval section ring joints were originally designed for the now obsolete round bottom groove. Both the Oval and the Octagonal cross section are interchangeable on the flat bottom groove design.            Package       Ordering  Information   When ordering gaskets please specify the following: Gasket style and number Material Nominal pipe size and pressure rating or specific gasket dimensions        Company information 1,pecializes in developing sealing materials and gaskets about 15 years. 2, located in the south of Hangzhou Bay, near Hangzhou and Ningbo. 3,convenient transportation and good geographic advantages.
