When might I use GRP pipe in preference to traditional plastic pipe in the utilities industry?

TWI Frequently asked questions

GRP (also referred to as GRE - glass reinforced epoxy) pipes are used where extra stiffness and strength is required. Typical applications are:



Fire fighting mains pipes
Cooling water lines
Effluent lines
Sewerage and drainage lines
Process water pipes
Water purification pipes
Ballast water

The extra stiffness and strength is imparted by the E-glass fibres in the GRP pipe.
