Abstract
Pressure testing during almost two years have shown that Swage-lined test pipes have good long-life properties. There are, however, certain indications that Swage-lined pipes have a somewhat shorter long-time strength. The reason may be scratches that arises during the lining process. The scratches are not judged as life-time limiting as long as they are not deeper than 1 mm. Inner stress measurements shows large differences between Swage-lined and not Swage-lined pipes. For Swage-lined pipes the maximum tangential inner stress in the pipe wall have completely disappeared, at the same time as high axial inner stresses are measured (large relative decrease in length). 12 refs
