Carrier Pipe

Fibreglass Carrier Pipes can be fitted around the inlet and outlet piping from pump stations and valve chambers. They provide room for the pipe to move horizontally and vertically during ground consolidation, or in an extreme event like an earthquake.

The Carrier Pipe is supplied in short lengths in two halves that fit together at site. The bottom half is installed first, then the pipes are set in the centre with soft foam supports to position them. Then the top half of the Carrier Pipe is clipped over an onto the bottom half. Plastic strapping can be used to hold the two halves together during backfilling.

Carrier Pipe Starters can be fitted to the pump station and valve chamber to facilitate fitting of the Carrier Pipe. The Carrier Pipe Starters can be factory fitted when fibreglass pump stations and fibreglass valve chambers are used.

Pump Station to Valve Chamber

Pump stations and valve chambers are often located a short distance apart. If there is ground movement, the connecting pipes can become stressed and fracture at the ends. A full Carrier Pipe between the pump station and valve chamber gives more room for movement to occur and lessens the chances of failure occuring.

Outlet and Inlet Pipes

A short length of Carrier Pipe of say 1.5 metres can be installed on the inlet and outlet pipes of both pump stations and valve chambers. This reduces the chances of a shear failure occuring at the vessel wall.

Protection During Excavation

HDPE piping is commonly used on piping to and from both pump stations and valve chambers. It can be easily damaged during excavation for maintenance. A Carrier Pipe around the HDPE pipe protects it from damage by excavators, spades, shovels, and pick axes.
