The U.K. gas network spans 90,000 kilometers and the 50-year old cast iron mains are in continuous need of replacement, due to degradation from age, corrosion, traffic loading and ground movement.
Such failures can cause fracture, leakage and in severe cases gas explosion, so it is essential for companies such as Cadent to monitor the mains network regularly and prioritise the replacement of faulty pipes.
A system was developed to prioritise mains for renewal and, in 1986; the Mains Points Replacement Scheme (MRPS) was introduced.
We survey the network and help to identify mains for replacement, so that companies such as Cadent can supply gas safely and effectively.
