Condition Monitoring of British Gas Pipelines

  • M. J. Thomas


British Gas has used steel pipelines for bulk gas transmission since the early 1960’s. A 17,000 Km system of pipelines is now used to carry gas from its on-shore terminals to local distribution networks at pressures between 7 and 7b bar, and operating at stress levels up to 72% s.m.y.s. Whilst these pipelines were designed, constructed and tested to high engineering standards, the only monitoring initially was by surveillance, leakage tests, pipe coating checks, and monitoring of the cathodic protection systems. From operating experience by the early 1970’s concern was being expressed that, in common with any structure operating at high stress levels, a reliable form of condition monitoring was required to maintain the pipeline system in a safe condition.
