摘要

600293 A method of manufacturing a mechanically lined pipe (MLP) 2 being >500m long and having an outer pipe 4 and an inner liner 6a comprising at least the steps of forming the outer pipe 4 as a single length, forming the inner liner former 6a being >500m long and wholly or substantially the same length as the outer pipe 4, inserting the inner liner former 6a within the single length outer pipe 4, and expanding the inner liner former 6a within the outer pipe 4 to form the MLP.
