LEAK REPAIR CLAMP

Split sleeves are widely used for making repairs to a variety of high or low temperature pipelines, containing oil, water, gas, steam and chemical fluids.The clamp halves are joined by bolts to form a high integrity pressure vessel around the damaged or leaking pipe. Sealing is provided by elastomer seals of the highest quality selected for compatibility with the pipeline fluid and operating temperature.The Split sleeves may also be welded after installation to provide a permanent repair. It may be completely seal-welded with the pipe line in operation.

Split repair sleeves

for onshore installation
for offshore installation, with zinc anodes and marine epoxy
weldable, with heat insulating
with grider rings, if required.

Clamps are repair fittings that can be used to seal leak caused by corrosion or damage on onshore and subsea pipelines. These Clamps are tested to 1.5 times the design pressure. Steel Grider Rings prevent displacement & damage of packing during installation. Standard working pressure is 1000 maop. Higher working pressures with various lengths are available on request.

2. for offshore installation, with zinc anodes and marine epoxy coating.
3. weldable, with heat insulating gaskets.
4. with grider rings, if required.

Features

Standard Clamps are fitted with a high grade elastomeric seal made from Buna-Nitrile or Viton. In these applications the sealing load is achived through the bolt tensioning of the clamp studs (split sleeve design)

All Clamps are designed with an external pressure test facility that determines the joint integrity prior to commissioning.
Twin seal configuration is also available to allow inter-seal testing to be carried out during installation.
Clamps may be supplied for both topside and subsea repair applications.

Engineered solutions can be manufactured to use metal graphite composite seal that is provided in all Split Sleeve Clamp Mechanical Contractor products. Graphite based sealing ensures a chemically resistant, high temperature, high pressure seal that will not degrade in aggressive or harsh environments.

Clamps bespoke connector solutions can be provided by our dedicated engineering team.

Beneﬁts

Can be used in cases of leaking pipes or where wall thinning occurs. They are self-sealing, achieved by bolting of the clamp studs.
Standard clamps come in single seal arrangement, but double seal arrangement can be provided upon request.
Hydro tested to 1.5 times the clamp design pressure (or as per your requirements) Widely used for subsea and topside repairs.
Provide with wedge shape grooves to prevent slipping of seals during installations. Designed to ASME VIII
Can be provided with prep angles for welding on the pipeline as and when required.
