Metallic pipes tend to gradually lose their strength under the effect of corrosion and erosion reducing the original thickness thus compromising pipe integrity. Corrosion also increases pipe brittleness resulting in formation of cracks in the pipe wall which cause the pipe to leak. In addition to preventing leakage, composite repairs can also compensate for the strength loss due to corrosion. With over two decades of proven experience, H.B. Composites is ready to provide service in the area of equipment repair and maintenance

Maintenance Coupling

In many cases, especially in the oil and gas industry, pipe repair work using traditional methods such as welding is impractical due to flammable nature of working fluids and the possibility of explosion and fire. Moreover, system shutdown may result in tremendous costs. In such scenarios, H.B. Composites “Maintenance Couplings” are the best options to repair leakage without shutdown. The advantage of this methods is the absence of welding and related risks and its relatively low cost.
