Abstract: From studies of defect behavior and operational experience British Gas has concluded that on both technical and economic grounds periodic non-destructive evaluation of its gas transmission pipeline is to be preferred to overload (hydrostatic) testing as a means of assessing their structural integrity. Following a period of development, an inspection service to detect and size gross metal loss in 24 inch pipehnes was introduced in 1977 and to date some 1450 miles of this size of line have been surveyed. This paper reviews the inspection philosophy upon which vehicle design is based and the operational experience and performance achieved through its use. It is concluded that the inspection principles adopted by British Gas for both metal loss and cracking and the equipment engineered to allow their application to pipehnes meet the performance requirements of a revalidation system, Work to extend the technologies to a range of pipeline diameters and provide an inspection service to other operators are also described.
