RTJ Flange Repair – On-Site Ring Type Joint Flange Machining   RTJ flanges (Ring Type Joint) are widely used in high-pressure and high-temperature piping systems, making them a standard choice for API specification flanges. Typical applications include oilfield valves, pipeline systems, pressure vessels, and other critical industrial joints where leak-free performance is essential. Unlike flat face (FF) or raised face (RF) flanges, RTJ flanges use a metal ring gasket seated in a precisely machined groove to form a metal-to-metal seal. Key Characteristics of RTJ Flanges   Use solid metal ring gaskets instead of soft composite gaskets Feature a precision-machined groove to locate the gasket Create a metal-to-metal seal when compressed Softer gasket material flows into the harder flange surface for sealing Designed to resist over-tightening, vibration, and movement These features make RTJ flanges ideal for demanding operating conditions. On-Site RTJ Flange Groove Machining   RTJ groove dimensions must comply with ASME B16.5 standards. This work can be performed on-site using portable flange facing machines, eliminating the need for flange removal and reducing downtime.   MT Portable Machines flange facers are designed to machine RTJ grooves without additional optional attachments, ensuring efficient and accurate on-site repair. RTJ Machining Capabilities Portable flange facing machines typically use one of two axial feed systems to create the required 23° sealing faces:   Automatic axial feed Ideal for precision RTJ machining and long-duration work. Typical models: FI40, FI60, FI80 Striker (kick-feed) axial feed Axial movement is controlled by a striker mechanism or manually by the operator. Typical models: FE12, FI26   Both systems also support manual feed for fine adjustments.

FI60E Flange Facing Machine Restores Flange Integrity at Pressure Vessel Manufacture At the beginning of 2025, our team delivered a state-of-the-art FI60E flange facing machine to a customer based in Hangzhou, China. The customer specializes in pressure vessel manufacturing and was facing a critical challenge with flange welding distortion. This distortion had caused severe deviations in the flatness of the sealing faces, making it impossible to meet the required sealing standards for their pressure vessels. The customer urgently needed a solution to repair these flanges and restore their integrity. The Challenge: Flange Distortion and Sealing Face Repair The customer's pressure vessel production involved large, heavy-duty flanges, and during the welding process, certain flanges suffered from thermal distortion, resulting in misalignment and an unacceptable flatness of the sealing faces. These distortions posed a significant risk to the integrity and safety of the pressure vessels, and without the right equipment to correct the issue, production could be delayed. After discussing the customer's needs with their technical team, our engineers identified that the flanges in question typically had sealing face diameters of 1.5 meters or smaller. Based on this, we recommended our FI60E flange facing machine, which is designed to repair sealing faces ranging from 320mm to 1500mm in diameter. The FI60E is particularly well-suited for their operation, as it can efficiently restore the sealing face flatness of smaller flanges—something the customer was experiencing on a regular basis. Solution: Tailored Service with a Maintenance Contract The customer required an immediate and cost-effective solution for routine flange repair. Given that they only occasionally required repairs for flanges with diameters larger than 1.5 meters, we proposed a framework agreement that would cover all their flange repair needs for an entire year. This included a guaranteed service response time of just three days for any large-diameter flange repairs. With this contract in place, the customer no longer had to worry about lengthy negotiations for each repair job. The fixed pricing ensured that any large-flange repairs would be completed promptly, allowing the customer to focus on their core manufacturing processes without delays. This type of framework agreement has become increasingly popular among end-users, as it eliminates the need for time-consuming price discussions. Instead of worrying about potential cost overruns or project delays, customers can rest assured that the repair services will be carried out swiftly and at a predictable cost. This predictable service model not only speeds up the repair process but also helps prevent unforeseen maintenance delays that can disrupt production timelines.
