Delivery of a Full Order of API RTJ, Ring Joint Gaskets For Offshore Oil & Gas Operator for High Pressure Flange Leakage Risk and – Old Problem Finally Solved, Project On Successful Delivery and Building a Long-Term Working Relationship We provide precision-made oval and octagonal RTJ metal ring gaskets for extreme high-temperature, high-pressure flange sealing applications.
Offshore platform piping and valve systems engineering contractor client. Prior to working with us, they were having frequent issues with sealing reliability. Their existing gasket supplier was unable to provide a consistent dimensional tolerance for the RTJ grooves and due to fluctuations in pressure and temperature on the Platform, several flange joints developed micro-leakage during the pressure testing. The customer urgently required an ASME B16.20 compliant metal ring gaskets all sizes; choice of carbon steel, stainless steel, other alloy steels with octagonal & oval profiles. All parts are to be fitted on pipeline flanges, valves and pressure vessel cylinder heads, making strict traceability and third-party material testing certificates a must.
The inquiry came from our technical sales team, working conditions of high pressure, corrosive process medium and including constant vibration from offshore equipment. We explained the differences between the octagonal RTJ gaskets and the oval RTJ gaskets. Extra emphasis on sealing stability for standard FRTJ flanges and simple repeated assembly and inspection make the octagonal ring joint gaskets more suited than the oval ones. We prefer the oval-style RTJ gaskets used for older groove types of flanges based on the customer flange drawing and API specification.
We suggested alloy steel RTJ gaskets for the most critical high-stress joints, and stainless steel grades for general valve connections, while carbon steel RTJ rings were used to keep the overall project budget down to non-corrosive auxiliary pipelines.
After the material was confirmed, our production department had precision CNC machining of solid metal ring gaskets. All of the solid ring gaskets were dimensional inspected, surface finish checked and hardness tested before it was packaged. Operating to level of composites, and not soft gaskets, RTJ ring joint gaskets depend on the metal to metal contact as the ring with flange groove and any scratches or out-of-tolerance profiles of drafts will break the sealing line. Every batch was heat numbered and serial numbered for full material traceability – this was one of the client delivery guarantee requirements from the client’s QA department.
We updated progress transparently throughout the creation process, held as many pictures came out of semi-finished and finished product, and synchronized the delivery schedule with the platform manual shutdown maintenance windows. Upon the cargo’s arrival at the warehouse, the client was invited for an in-bound inspection, to it they also verified all MTC documents. These gaskets withstood the hydrostatic pressure test with all zero leaks. The on-site engineers by their experience said that smooth to a high degree of finish accurate profile aided the bolt tightening better when compared with older supplies.
This accomplishment of the on-time delivery, it became an academic framework collaboration agreement starting from a one-time: urgent order with the customer now we are their RTJ ring joint gasket, spiral wound gaskets and other flange sealing components.
This case speaks to the benefits of accurate gasket selection and precision manufacturing. When it comes to high-risk API flange sealing, it is the right profile selection (octagonal or oval), as well as selecting the proper material grade and ensuring strict quality control that is more critical than the cheapest unit cost. This sealing solution prevented an unplanned shutdown, cuts inspection and replacement cost, and operably providing safety and long-term performance in harsh operating environments.
