Maintenance and strengthening technology of FRP pipe

1 Welding Technology

This type of repair is intended for the application of weld to pipe defects to recover the strength of steel. Surface welding is mainly suitable for small single point defect patch welding to small areas of corrosion, for large area corrosion of the sleeve. The advantage of the welding method is the low cost..

2 clamp technology

The clamp technology is the application of mechanical clamping device to restore the strength of the pipeline. This technology avoids the direct welding of service pipeline, thus avoiding some risks of direct welding.. However, its disadvantage is that the construction and implementation of fixture is relatively complex, high cost, clamp corrosion is also a big problem.

3 fiber composite repair technology

The technology of fiber composite repair has been used in the steel tube since 1990.. It strengthens the high strength of fiber material and the adhesive resin coating outside the pipeline, so as to recover the strength of the pipeline.. Its advantage is that it eliminates the risk of welding, off the pipeline, the environment exposed and other issues. Between the welding and the clamp technology, the overall performance is the best in the three. Composite repair technology is widely accepted practice in the global pipeline company..
