FI40 Flange Facing Machine Successfully Restores RTJ Seal Groove On-Site

Our recent collaboration with a valued client has once again demonstrated the exceptional capabilities of our FI40 Flange Facing Machine. The client shared an on-site machining photo showcasing the successful restoration of an RTJ (Ring Type Joint) seal groove using our advanced equipment. The machined seal groove met all acceptance standards, proving the FI40 to be a reliable solution for repairing RTJ seal grooves affected by corrosion or welding deformation.

What is an RTJ Seal Groove?

The RTJ seal groove is a critical component in high-pressure and high-temperature piping systems. It is designed to accommodate a metal ring gasket, which creates a tight seal between two flanges. The precision of the groove’s dimensions and surface finish is essential to ensure a leak-free connection, especially in demanding industrial environments such as oil and gas, petrochemical, and power generation.

Common Causes of RTJ Seal Groove Failure

RTJ seal grooves are prone to failure due to several factors, including corrosion and welding deformation. Corrosion, often caused by exposure to harsh chemicals or environmental conditions, can degrade the groove’s surface, leading to improper sealing and potential leaks. Welding deformation, on the other hand, occurs during the installation or repair of flanges, where thermal stress distorts the groove’s geometry. These issues can compromise the integrity of the flange connection, resulting in operational downtime and safety risks. Traditional repair methods often require disassembly and off-site machining, which can be time-consuming and costly. However, with the FI40 Flange Facing Machine, these challenges can be addressed efficiently on-site.

The FI40 Flange Facing Machine: Precision and Efficiency

The FI40E model is equipped with a servo motor as its power source, providing constant torque output and infinitely variable speed control. These features offer significant advantages when machining RTJ seal grooves, particularly in controlling the surface roughness of the groove. The FI40’s ability to automatically feed in both the axial and radial directions ensures high precision in the machining process while eliminating the need for manual intervention. This not only guarantees the accuracy of the machined surface but also simplifies the operator’s task, making the process more efficient and user-friendly.
