We are manufacturer, Exporter and Supplier of Double band repair clamp also known as Split Repair Clamps are an essential part of our suite of pipeline integrity products. Available in a wide variety of sizes, ratings and arrangements, the clamp product line can be supplied independently or as an add-on to larger repair systems.
What is Split Repair Clamps ?
The sealing arrangement provides full containment around the damaged section of pipe (leak sealing only). If required, we can design the clamp to have a gripping section to provide a fully permanent structural repair that can be DNV-GL Product Certified.
Suitable for onshore, topside, diver installed or deepwater remote repair, our engineered MORGRIP clamps provide an increased lev-el of safety and reassurance when repairing critical pipelines or being stored as part of an emergency pipeline repair system or contingency plan.
Our clamps are application specific and designed, forged and fabricated to the exact requirements of the operator and repair location. This bespoke service ensures a fully configurable solution of the highest quality.
