118 Fabricated Repair Sleeve



The JCM 118 Repair Sleeve repairs large pipe in systems which require high working pressure capability. Engineered specifically for the internal pressure forces involved with large diameter pipe and its working characteristics. The Available in pipe sizes up through 120” and larger with several design options for the specific application. The strong and lightweight steel directly reinforces the pipe wall on the circumference of the pipe.

Heavy Duty Design – large fitting components, spacious bolt holes and heavy hardware combine to make installations in less than ideal environments easy and fast. The 118 especially lends itself for easy underwater and low visibility applications.

Maximum Gasket Sealing – heavy duty materials provides high levels of bolt torque transferred directly to gasket sealing compression. Higher bolt torques maintain greater working pressures. Minimal Pipe Excavation – the 118 sleeve requires limited pipe exposure around the damaged area. Full section joint exposure of underground pipelines is eliminated.

Low Profile Stance – the hydro-mechanical lip gasket is trapped both internally and externally in a recessed groove that provides a low profile stance on the pipe eliminating the chance of gasket displacement or “blow-out” in high pressure applications. All 304 or 316 Stainless Steel available.

Suitable for these types of damage:
