Pipe repairing sleeves

Composite sleeves or full composite wraps are the latest innovation in pipeline defect repair where leakage or spillage has not started.

They are well suited for repairing contoured pipelines and sections of pipelines where fittings are installed, such as small take-off points or metering points.

They are capable of restoring damaged pipelines to their original Maximum Allowable Operating Pressure (MAOP), with the added benefit of coating the pipes to protect them from corrosion. Today, commercially available prefabricated sleeves (designed and cured in a factory for rapid installation on site and also wet sleeves that are wrapped and cured on site as needed.

Most popular and CPL approved (Chevron Pipeline Company) composite sleeve is Clock Spring® which are made up of corrosion-resistant high tensile fiberglass material.

However, ASME B31.8 only accepts such repairs in case “proven through reliable engineering tests and analysis.” Where possible, composite sleeve wrapping is carried out at one-third of the operating pressure so that sleeve can share hoop stress once the pipe is restored to regular operation.

During application, fiberglass is wrapped around a damaged portion of bare pipe, after cleaning, in layers, and a filler metal is applied in each layer. For dented areas, special hardening filler material (provided by composite sleeve manufacturer) is used before the application of sleeve wrapping. Pipeline pressure should be kept reduced until the completion of sleeve installation and curing time.

plit reinforcement sleeves, are weldable repair sleeves that encaptulate a pipe. The halfsole units have beleved axial joints for welding to the damaged pipe.

Dented, wall thinning or weaken areas are strengtened by the split repair sleeve.


Reinforcement pipe sleeve repair sleeves have square cut butt ends for welding to the pipe. Weld protection strips may be installed in a grove cut as an option.

Closing clamp bolts may be attached for final closing before welding. Strap clamps or manual pipe jacks may also be used for final closing.


The units may ship with shop prime or no finish coating.

Backing strips may be milled on the inside. Compression closing for final welding may be accomplished by removable bolt clamps, .

Pipe repair for ship piping, oil/gas lines, water, steam and chemical pipes.

Available for all American and International pipe sizes.

Split repair sleeves are supplied, based on the client’s material requirements and lengths.
