Ring-Joint gaskets are manufactured in accordance with API -6A, API-17D and ASME B16.20 standards, approved by American Petroleum Institute to PSL 4 Standard, the highest quality rating-We ensure faster delivery with better inventory of regular RTJ's and urgent requirement of non standard or exotic material also can be addressed in the shortest time as we make the gasket from the very base material, all under one roof. Our complete in-house casting and machining facilities enables us to make our own raw ring castings, ensuring fast turnaround and complete commitment to quality at every stage of manufacture.
Our RTJ's can be traced back to the scrap material used and can be ratified to NACE specifications on request. The performance of the gasket is based on the geometrical accuracy, surface finish of the sealing area and the hardness of the gasket material. The softer the gasket than the flange the better will be the sealing. This concept has been well ingrained in the process to make gaskets of hardness as low as 110 BHN in SS316. We make sure that the hardness of the gaskets are 10% below the upper limit specified by API standards. Soft Iron and Low carbon steel are given protective electroplated zinc coating of 10-12 micron thickness. RTJ gaskets material with recommended Max Hardness and identification as specified by API and 16.2 ASME standards are listed along with non standard material, any custom required material also can be taken up to demand.
R Ring Type Joints are manufactured in accordance with API -6A and ASME B16.20 standard to suit API 6B, ASME/ ANSI B16.5 flanges. Available in both oval and octagonal configurations, the oval ring fits the rounds and flat bottom ring groove flange while the octagonal fits only the modern flat groove flange.
RX Ring Type Gaskets are manufactured in accordance with API-6A and ASME B 16.20 standard to suit API 6B, ASME/ANSI B 16.5 Flanges. The RX is a pressure energized version of the R octagonal gaskets and fits the R type flat bottomed groove. The RX has an increased height and utilizes the internal pressure to energize and improve the seal as internal pressure increases .Some RX sizes have pressure relief hole to equalize pressure both sides of the sealing faces.
BX Ring Type Gaskets are manufactured in accordance with API-6A and ASME B 16.20 standard to suit API 6B Flanges. All BX gaskets incorporate a pressure balance hole to equalization of pressure which may be trapped in the grooves.
SBX subsea Ring Type Gaskets are manufactured in accordance with API-17D PSL 4 standard. Two pressure holes in the SBX ring cross section prevent lock when connections are made up underwater .Two options are provided for drilling the pressure passage holes.
