Technology Background:

●Industrial pipe and piping systems are easy to be eroded or corroded by the influences of high pressure, high temperature, humidity and harsh chemicals, etc. Such erosion or corrosion will lead to damages of structural integrity and pressure bearing ability of the pipe and the piping systems. In some severe circumstances, such damages will cause serious consequences such as leaking and explosion of the equipment or even shut down of the whole plant。

●Compared with common pipe repair technologies nowadays, such as patch welding, sleeve assembling or pipe replacing, CFRP pipe and piping systems rehabilitation technology is economically preferred because no hot work or down-time is needed. Although clamp sealing method has obvious advantage in restoring the leaking pipeline, it has disadvantages of operational complexity, time demanding and high cost, etc.

●CFRP pipe and piping systems rehabilitation technology is widely used from the beginning of 1990’s in most of the developed countries. The technology has excellent properties such as high modulus and strength, low weight, anti-corrosion, time lasting, easy to handle, etc.

Gunnerys CFRP Pipe and Piping Systems Rehabilitation Technology：

●This innovation state-of-the-art technology is researched and developed based on our company’s professional experiences in the field of industrial services. The CFRP pipe and piping systems rehabilitation composite systems are mainly comprised of plain waved carbon fiber reinforcing material, epoxy matrix material, epoxy primer and filler. Taking advantages of carbon fiber’s extreme strength and epoxy’s strong adhesive property, the CFRP composite form an exterior wrap at the surface of the working pipe to restore its original design.

●This technology provides a new pipe and piping systems rehabilitation solution for industries such as petroleum and natural gas long-distance pipeline, refinery plants, chemical plants, power plants and steel plants, etc.
