Glass fibre reinforced piping systems have considerable advantages over alternative materials for piping systems. This is mainly due to their high corrosion resistance.The use of GRP pipes is limited due to the lack of quality assurance. As with other piping systems the joint is the weakest point. The paper describes the effort made towarde a better quality mntrol and understanding of the failure through determination of acceptance criteria and development of nondestructive testing methods for adhesively bounded joints.
