Bolted sleeves, bolted sleeve clamps, split repair clamp, Boltable Split Sleeve Repair Clamp, Split Type Pipe Repair Clamp, Flange leak repair clamps, Leak Repair Clamp  are widely for making repairs to a variety of high or low pressure and high or low temperature pipeline, including oil, water, gas, steam and chemical process. The clamp halves are joined by bolts to form a high integrity pressure vessel around the damaged or leaking pipe.

Split repair sleeve
1. for onshore installation
2. for off shore installation, with zinc anodes and marine epoxy coating
3. weldable, with heat insulating gaskets
4. with girder rings, if required

APPLICABLE INTERNATIONAL STANDARDS

The design, engineering and supply of the fire tubes (two off) shall conform wherever applicable, and unless otherwise specified & agreed, to appropriate API, ASTM, ANSI ASME or equivalent standards / codes and also to internationally-accepted standards and practices. All Standards and Codes followed for the Design shall be of latest version/edition.

1. Standard Clamps are fitted with a high grade elastomeric seal made from Buna-Nitrile or Viton. In these applications the sealing load is achieved through the bolt tensioning of the clamp studs (split sleeve design)
2. All Clamps are designed with an external pressure test facility that determines the joint integrity prior to commissioning
3. Twin seal configuration is also available to allow inter-seal testing to be carried out during installation Twin seal configuration is also available to allow inter-seal testing to be carried out during installation
4. 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 Connector 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 5 times the clamp design pressure (or as per your requirements)
• Widely used for subsea and topside repairs
• Provided with wedge shape grooves to prevent slipping of seals during installation
• Designed to ASME VIII
• Can be provided with prep angles for welding on the pipeline as and when required

WELDABLE SPLIT SLEEVES

All clamps can be fully prepared for welding after installation (welding procedure is available on request).

Heat insulators (parallel to the seals) protect the seals from heat during the welding of the sleeves to the pipe.

*Clamps with longer lengths available on request.

EASE OF INSTALLATION AND MAINTENANCE

All split sleeves are designed to be installed with the most common tools available and are readily field repairable, including full seal replacement

SPLIT SLEEVES ARE SUITABLE FOR SOUR ENVIRONMENT

This type of split sleeve is designed to be used in hydrogen sulfide (H2S) bearing hydrocarbon service.

For sour services, the body material will meet NACE MR0175.
