CSNRI DiamondWrap

DiamondWrap® is a repair system applied on site composed of a specific carbon fiber, two-component epoxy and a hardfacing resin. It functions as a reinforcement and leak repair system to restore the original strength of the pipe circumferentially and axially.

DiamondWrap® is an alternative to clamps or pipe replacement. It is regularly used in factories, refineries, terminals, storage areas and offshore all over the world. It is suitable for complex geometries such as tees, flanges and pipes of different diameters. It can repair leaks and is easily applied in harsh environments and on complex piping.


DiamondWrap® can be easily installed cold with little pipe breakage. It has been used many times with success in the presence of internal corrosion due to chemicals where the integrity of the piping has failed.

The specific epoxies developed for use with DiamondWrap® are unmatched in quality and performance. With DiamondWrap® HTA™ and Diamond-Wrap® UHT™ are provided special high temperature and chemical resistant epoxies.
