PLIDCO Split+Sleeves
PLIDCO Split+Sleeves are mechanical pipe repair clamps used to seal leaks caused by corrosion or third party damage to on-shore and off-shore piping. Featuring a unique, patented construction, the Split+Sleeve allows repairs to be made on-stream. Steel GirderRings™ prevent displacement of gaskets by leaking fluids during installation. The seal is completed once the Split+Sleeve is bolted. These fittings are easy and safe to install and can be completely seal welded with the line in operation, if it is intended to be used as a permanent repair. The Split+Sleeve can be used for repairs to both high and low pressure and temperature pipelines carrying oil, gas, steam, chemicals and water.Standard working pressure is 1000 PSIG with higher working pressures available. Fittings are tested to 1-1/2 times recommended working pressure. All sizes, lengths and pressures are manufactured. Standard fittings for API pipe sizes 1½" through 48". Higher working pressure, longer lengths and other sizes are available upon request.
PLIDCO Split+RepairElls
PLIDCO Split+Repair Ells function the same way as the PLIDCO Split+Sleeve. These fittings are available for long radius, short radius, screwed and socket welded applications. PLIDCO Split+Repair Ells can be manufactured for any angle, pipe size, and working pressure of 1000 PSIG and higher upon request. The PLIDCO® Split+RepairEll is fast and easy to install by simply bolting the halves over the leaking ell. Available packing materials include Buna-N, Neoprene, Viton, Kevlar and Silicone. Fittings may be seal-welded if required.Benefits of Split+Sleeves and Split+Repair Ells:

Body and seal gland design has over 55 years of proven success
PLIDCO Smith+Clamp
The PLIDCO Smith+Clamp is designed to seal high-pressure pit-hole leaks in piping. The clamp features a unique, patented, pilot pin that guides a cone point into the pit hole and centers it on the leak. Pressure applied behind the cone by a force screw provides the minimal force required to seal off the leak. Draw bolts at the bottom of the fitting hold the clamp in place. Standard sizes of the PLIDCO® Smith + Clamp range in pipe sizes from
1-1/2” through 48” and at working pressures up to 2000 psi. Special sizes can be custom designed.
PLIDCO Flange+Repair Rings can be installed by your own personnel. There is no drilling or altering of flanges. On a scheduled turnaround, they can be removed, flanges cleaned, the gasket replaced and the flanges put back in service. The PLIDCO Flange+Repair Ring can be reconditioned and used again. Standard packing material is non-asbestos aramid fiber. Non standard packing material can be specified for product compatibility when the standard packing is not suitable. Standard flange sizes are 1/2” through 12”, ANSI 150 thru 600. Larger or special sizes, higher temperature and pressure ratings are available on application.
PLIDCO Weld+Ends enable pipe sections to be joined without special preparation of the pipe ends.PLIDCO Weld+End couplings are used for joining high and low pressure pipelines carrying crude oil, gasoline, gas, steam, asphalt, chemicals and water. Patented PLIDCO Weld+Ends allow pipelines to resume operation immediately at recommended pressures, keeping downtime to a minimum. The PLIDCO Weld+End slides onto the cut pipe ends; after fully tightening the clamping and thrust screws, the pipe is joined and a leakproof seal is established. If necessary, the coupling can be welded, and welding can be delayed until conditions are safe–with the pipeline in operation. When welding is not feasible, and excessive end-pulling loads are involved, additional rows of clamping screws or additional PLIDCO Clamp+Rings may be used. Standard sizes of PLIDCO Weld+Ends couplings range in API pipe sizes from 1-1/2” through 48” and at working pressures up to 2000 psi. Special sizes, diameters, lengths and pressures can be custom designed. Buna-N packing is standard, but other packing materials are available. Benefits of PLIDCO Weld+End couplings include:
The PLIDCO+Flange is a fitting designed for making bolted tie-in connections on prefabricated expansion and rework projects. These fittings are easy to install, even in hard-to-reach locations such as high overhead piping, conduits and tunnels, tight manifolds or in hazardous locations. No special preparation of the pipe ends is necessary. Like other PLIDCO products, the PLIDCO+Flange provides a pressure-tight seal, with no need for welding unless specified. The fitting can be removed and used again, or welded later with the pipeline in operation if a permanent installation is desired. Benefits of PLIDCO+Flanges include:
Mechanical or bolt-on type PLIDCO Hot+Tapping Saddles allow branch connections to be made into existing pipelines in hazardous areas without welding. Special designs are available and can be custom built for specific needs and specifications. Available with full size branches, in any range of sizes and pressures with threaded, welded or flanged outlets. Buna-n packing is standard, but other packing materials are available. The PLIDCO Hot-Tapping+Saddle includes design criteria per code covering branch connections on pipelines. Benefits Include:
PLIDCO® Riser-Type Weld+Ends are designed to simplify the replacement of underwater risers on offshore gas and oil lines–without welding underwater. This fitting has additional clamping and thrust screws to provide a seal for high pressure and for resisting extreme end-pull. Installation is rapid. The Riser-Type Weld+Ends is socket-welded at the surface to the new replacement riser and lowered into the water. A diver cuts out the old riser, stabs the new fitting over the cut-off pipe, then tightens the clamping and thrust screws for a complete leakproof seal without welding. Available in all standard sizes; special sizes as specified. Buna-N packing is standard, other packing available on application.
