Glass-fibre Reinforced Plastic pipe (GRP) systems, also known as FRP pipe systems, have been successful in the world’s markets for more than 50 years. During this time, they have developed into a modern pipe material that is predominantly convincing thanks to its light weight, corrosion resistance, smooth inner surface and easy installation.
Continuously wound GRP pipes are also popular in AP and the Middle East where they have provided well-accepted concepts to many industries and in many applications for many years. GRP pipes also had a proven design life as known in some case histories for a design life of more than 33 years.
All piping in general has a certain requirement related to design and installation. GRP piping as a semi rigid material shares over 80% of these requirements with other piping materials, however in this presentation we will highlight the remaining specific requirements related to system design, materials qualification and site installation.
Although we will try to present several modes of failure of GRP piping as real cases in terms of catastrophic failure, weeping De-lamination, cracking. we will share several root causes reports identifying what went wrong in terms of installation, design, operation and testing. The analysis should not only consider the visual criteria, but also some engineering tools and NDT methods/techniques to identify the defect, type, size, location trying to propose a best solution to avoid re occurrence.
