Ring Type Joints

Ring type joints excel in high-pressure applications such as oil and gas exploration and production. RTJs are also used on valves and pipework assemblies in refineries and other process industries.

Ring Type Joints

Available in both oval and octagonal profiles, standard Flexitallic style R ring type joints are manufactured to meet both API 6A and ASME B16.20 sizes and ratings. Also available are Flexitallic Style RX ring type joints which energizes on assembly. This type is designed to fit the same groove as a style R therefore making them interchangeable. For very high pressures, often found in sub-sea wellhead and Christmas tree systems, the Flexitallic style BX is used. Subsea versions of all styles are available with pressure balance holes.

We can also supply special RTJ and bespoke solid metal gaskets for topside and subsea blow-out preventers.

RTJ gaskets can be supplied in a wide range of stainless steels, Inconel alloys and other specialist metals. Coatings available include zinc, Xylan and silver.

Spiral Wound Gasket

To combat the effects of pressure and temperature fluctuations, flexibility and recovery are essential.

Spiral Wound Gasket

The necessity for a gasket to have the ability to recover cannot be over emphasised. The effects of pressure and temperature fluctuations, the temperature differential across the flange face, together with bolt stress relaxation and creep, demand a gasket with adequate flexibility and recovery to maintain a seal even under these varying service conditions. The Flexitallic Spiral Wound Gasket is the precision engineered solution to such problems, meeting the most exacting conditions of both temperature and pressure in flanged joints and similar assemblies and against virtually every known corrosive and toxic media.
