PIPELINE REPAIR SLEEVE

Pipeline Repair Sleeves are widely used to repair a variety of high or low pressure and high or low-temperature pipeline processes, including oil, water, gas, steam, and chemical processes. Bolts join the halves of the clamp to form a high integrity pressure vessel around the damaged or leaked pipe.

Sealing is provided by molded elastomer seals of the highest consistency, selected for compliance with pipeline fluid & operating temperature. These sleeves may also be welded to turn out after installation to be a permanent seal if conditions justify the additional cost.

Pipeline Repair Sleeve are a key part of our portfolio of items for the safety of pipelines. The clamp product line can be sold individually or in a wide variety of sizes, grades, and configurations as an add-on to larger repair systems.

Pipeline Repair Sleeve add a new dimension to the timely and permanent repair work on your pipeline. They are used to repair high and low pressure and temperature pipelines – offshore and onshore – that carry oil, gas, vapor, chemical processes, and water. Click here for API 5L Pipe Sleeve.

The clamps of the Pipeline Repair Sleeve are thoroughly static-tested hydro to 1.3 times the required working pressure. All Clamps are prepared using a half-inch vent port, depending on the client’s size and needs & specifications. The sleeves are all made in accordance with API specifications. They conform to specifications for consumers & design requirements for the industry. All of our sleeves are easy to install and to wear. They were designed to be easily installed with the most commonly available tools & readily repairable.

Pipeline Repair Sleeve clamps are made according to the materials that the customers require. The materials used are of impeccable quality which conform to the specifications of the industry. Pressure classes ANSI 300, 400, 600, 900 & 1500 are added. Form monitoring and stress analysis was carried out using body components that are appropriate for normally corrosive facilities. Only girder rings can be mounted according to the specifications of the clients. Double row sealing design is used in cases where pipeline leakage is very expensive as is the case in pipelines carrying gases.

Heat insulators (parallel to seals) shield the seals from heat when the sleeves are welded onto the tubing.

All Pipeline Repair Sleeve clamps may be prepared to weld after installation. They are shielded from heat during the welding of the sleeves to the pipe heat insulators running parallel to the seals. We would make such clamps with longer lengths if requested by the customers.
