Split sleeve boltable repair
Westatlantic Class Split Repair clamps: repair onshore and offshore pipelines.
ANSI pressure classes 300, 400, 600, 900, 1200 and 1500 are available.
Pipe Remains In Service During Installation
Rugged, reliable design split repair clamps for oil, gas and chemical fluids for high temperatures and high pressures.
View complete ANSI Table Chart.
Hinge plates and lifting eyes simplify field installation .
Sealing is provided by elastomer seals compatible with the pipeline fluid and operating temperature.
Split sleeves may be welded after installation.
The clamps are fully compensatory pressure vessels, hydrostatically tested to 1.3 times the rated working pressure (as per ASME Section VIII Div.1 clause UG-99) All Clamps are equipped with a 1” NPT vent port.
NBR or VITON elastomer seals, compatible with the line fluid and ambient temperature, will be installed into the split sleeves.
Gaskets are replaceable without any special tools.

Girder split clamp models are suitable for high temperatures and with pressures up to 3700 psi.
Split Repair Sleeves can be equipped with hinge plates and lifting eyes to simplify field installation.
NBR and Viton packing firmly kept into place with steel girder rings.
Hydrostatic test certificates are supplied with each delivery.
Pipe elbows high pressure repair clamp:
Higher friction between the fluid and pipe wall at an elbow, cause leaks to occur at pipe bends.
Elbows are identified by curve, angle or radius definition.
Elbow clamps are widely used to repair a variety of high or low pressure rating class pipelines, including oil, water, gas and petrochemical process.
The clamp halves are joined by bolts to form a high integrity pressure vessel around the damaged or leaking pipe.
Elbow repair clamps may be installed without shutting down the pipe line.
Sealing is provided by elastomeric seals selected for compatibility with the pipeline fluid and operating temperature.
Elbow repair clamps of various angles may be repaired.
Split repair sleeves, manufactured to the outer dimension of the elbows offer the best solution pipe angle repair.
Repair pipe elbow leaks and weak or damaged elbows with bolted elbow repair clamps. Elbow repair clamps are designed for ANSI Pressure classes 300-1500#. Design based on API 6H. Design calculation ASME Sec. VIII Div. I.
Flange Repair clamps are designed for easy installation. No special surface preparation is required prior to installation.
The product can be used multiple times. Injection via injection sockets is utilized to fully seal the compartment. In case of a small gap between the line flanges, gaskets can be installed for temporarily sealing prior and during injection.

Repair Clamp RH-2 Model
RH-2 stainless steel repair clamps can be used to repair leaking pipes up to 30 bars - 435 psi.
Installation can be done by maintenance staff, no special tools are required. Products are easy to keep in stock and offer instant repair and quick savings. Available with NBR and Viton rubber.
Installation can be done by regular maintenance personnel, the products are easy to keep in stock and offer instant repair and quick savings.
- All metal parts: stainless steel AISI 304 or AISI316L, passivated.
- Double band (two sections) with a working range of 20-22 mm depending on the diameter.
- V gasket, steel reinforced to form the pressure chamber.
- Standard NBR rubber gaskets.
- Bridge plates are vulcanized into the rubber gasket.
- Bolts are PTFE (Teflon™) coated to prevent galling.
- No loose parts that may get lost during installation.
- No special tools required: a simple wrench will do the job.
- Under most circumstances the clamps can be installed. without releasing the pressure on the pipe.
The clamps can be used to repair the following pipe types:
- Ductile Iron (DI) - PE coated steel
- Cast Iron (CI) - PVC*
- Steel (St.) - GRP*
- Asbestos Cement (AC) - PE*
If pipe repair clamps are to be used on plastic pipes, please always contact Westatlantic for more information regarding the
application and restrictions on these pipe types.
RH repair clamps should be used under following conditions:
- The width of the clamp should be at least equal to the pipe OD.
- The width of the clamp should be 150 mm greater than the length of any crack on pipes with an outside diameter up to 350 mm.
On larger pipes this should be at least 200 mm.
- For PVC pipes, the width of the clamps should be 50 % longer and bolt torque should be reduced by 50 %.
- The maximum allowable distance between two pipe ends should not exceed 10 mm.
- The maximum allowable deflection is 2 degrees.
- The maximum allowable offset should not exceed 3 mm.
