Avoid Costly Shutdowns

Our Flange+Repair Ring is designed to act fast by sealing a leaking gasket on the outside diameter of the flange set. This can be done with the pipeline still in service reducing costly shut downs. Once the PLIDCO Flange+Repair Ring is torqued to the correct specifications, the leak will follow the path of least resistance to the flange bolts. We solve this issue by injecting sealant through the injection ports to fill the gaps around the flange bolts.

PLIDCO’s Flange+Repair Ring is typically available in standard sizes to be installed on flange sizes 1/2″ through 24”, ASME B16.5 150# through 600#. Custom designed Flange+Repair Rings can be designed for various applications outside of this range.

Our Flange+Repair Rings are designed in accordance with ASME Section VIII, using pressure vessel code approved materials, such as, ASTM A516 Gr. 70, ASTM A193 Gr. B7, and ASTM A1949 Gr.2H. Other materials are available upon request.

PLIDCO offers many packing/seal material types and sealant options in order to ensure proper compatibility with the pipeline contents. Our Flange+Repair Rings can be removed during the next scheduled turnaround, reconditioned, and returned to customer stock and ready for the next emergency.

Wondering why customers trust us? We are the only manufacturer in the industry to offer a 5-year limited warranty on our pipeline repair products.
