Repairing a Split Sleeves are used to repair a wide range of high and low-pressure, high and low-temperature pipelines, including oil, water, gas, steam, and chemical process pipelines. Bolts connect the clamp halves, forming a high-integrity pressure vessel around the broken or leaking pipe.
Molded elastomer seals of the finest quality are used for sealing, and they are chosen for compatibility with the pipeline product and operating temperature. If the circumstances warrant it, these sleeves can also be welded after installation to create a permanent seal.
Repairing a Split Clamps are an important feature of our pipeline integrity product line. The clamp product line is available in a wide range of sizes, ratings, and configurations, and can be purchased separately or as an add-on to larger repair systems.
Split Repair Clamps provide a new dimension to your pipeline repair job, both temporary and permanent. They are used to repair oil, gas, steam, chemical process, and water pipes that are both offshore and onshore and carry high and low pressure and temperature. API 5L Pipe Sleeve can be found here.

PROPERTIES OF SPLIT REPAIR SLEEVE
The clamps of split sleeve are thoroughly hydro statically tested to 1.3 times the required working pressure. All Clamps are prepared with a half inch vent port depending on size and clients requirements & specifications. All the sleeves are made according to the API specifications. They match the design specifications of the customers & industry specifications. All our sleeves are easy to install & maintain. They designed so that they can be easily installed with the most common tools available & also can be readily repaired. Our split repair clamps are economically viable as they are made using the latest technology, improving the design techniques & materials which are also low in weight.
MATERIALS USED FOR SPLIT REPAIR SLEEVE
Split sleeve clamps are made as per the materials required for the clients. The materials used are of impeccable quality which are in accordance to industry specifications. ANSI pressure classes 300, 400, 600, 900 & 1500 are used. Design control and stress analysis are done with body materials suitable for normally corrosive services. Girder rings can also be installed as per the clients’ requirements. Double row sealing design are used in cases where leakage in the pipes are very costly like in the case of pipelines carrying gases.
