Chapter 7
Pipe Materials: Fiberglass
Publication: Water Pipeline Condition Assessment
Abstract
Fiberglass pipe is a composite structure manufactured from glass fiber reinforcements embedded in or surrounded by cured thermosetting resin. Properly the product is known as fiber-reinforced plastic (FRP) or glass-reinforced plastic (GRP); in popular usage the product type is referred to as fiberglass. Alternate nomenclature for fiberglass pipe is glass fiber reinforced thermosetting resin pipe (RTRP) and glass fiber reinforced polymer mortar pipe (RPMP). RTRP is fiberglass pipe without an aggregate, and RPMP is fiberglass pipe with an aggregate. This chapter describes how to inspect in-service FRP pipe to determine its condition, which forms the basis for assessing fitness for continued service and planning repairs. Three complementary types of inspection are external inspection with the equipment in service, external inspection with the equipment out of service, and internal inspection.
