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 non-asbestos aramid fiber.
Plidco® Flange+Repair Rings incorporate patented steel GirderRings to hold packing in place during installation. Normally available from stock in standard flange sizes 1/2″ through 12″, ASME class 150 through class 600. Larger or special sizes, higher temperature and pressure ratings are available.
Maximum temperature rating for the standard Plidco® Flange+Repair Ring is 700°F. Standard material is ASTM A516 Gr. 70 Plate, ASTM A193 Gr. B7 bolting and ASTM A194 Gr. 2H nuts. Other materials are available for higher or lower temperatures. NACE MR0175/ISO 15156 compliant materials also available.
