Plidco Flange + Repair Ring

Plidco® Flange+Repair Rings can be installed by your own personnel. There is no drilling or altering of flanges. On a scheduled turnaround the Plidco® Flange+Repair Ring can be reconditioned and used again. Give us your conditions — pressure, temperature, fluid — and we will recommend the proper sealant and packing. Standard packing is braided carbon fiber.

Plidco® Flange+Repair Rings are ideal for repairing industrial flange leaks of natural gas/methane (CH4), hydrogen sulfide (H2S) and carbon dioxide (CO2).
