Performance of reinforced thermosetting resin pipe systems in desalination applications: a long-term solution to corrosion — the Arabian Gulf example

Abstract

Throughout the history of desalination piping, corrosion has played a critical role in material choice, overall system design and, of course budget estimates for the life-cycle cost of the plant itself. Reinforced thermosetting resin pipe (RTRP) systems, also known as fiberglass, FRP, GRP or GRE pipe systems, introduced in the 1960s have been used exclusively in an effort to eliminate corrosion. The Arabian Gulf, infamous for its extremes in temperature and corrosive conditions, is a prime showcase for exhibiting the effectiveness of GRP pipe systems in combating corrosion, extending the life of the pipe systems and reducing overall running cost of the plant. Evidence of successful installations using fiberglass pipe systems in desalination applications is extensive since the early 1970s. Modern designs have seen a revolution with respect to the compilation of performance based specifications, in-depth experience across a broad spectrum of applications and the development of advanced manufacturing methods. The versatility of fiberglass systems is seen through its applicability to a number of services and operation conditions.
