Definition - What does Carrier Pipe mean?
Carrier pipe is the term used for a product pipe, which carries a liquid or gas from its source to its destination and is laid underground. A leak in a carrier pipe will either result in groundwater ingress into the pipe or a contamination of the environment with the product flowing in the pipe. Trenchless rehabilitation techniques are used to repair leaking carrier pipes.
Trenchlesspedia explains Carrier Pipe
Carrier pipes can be made of a variety of materials depending on the product that they carry. Steel, concrete, fibre and various forms of plastic are used, each meeting the specification required for their application. Products such as petroleum products, chemicals, gas, water and waste streams are all transported using underground carrier pipes. Leaks can be detected using non destructive inspection techniques like intelligent pigs, or hydrostatic pressure testing, which results in a pipe burst. Joints can also be inspected using packers and sealed with joint sealers as this is a common source of leakage for carrier pipes.
