Abstract

Sections of large dia. pipeline are isolated, for testing or subsequent repair if necessary, by freezing short lengths of a slug of water. A high pressure is applied to the area between two frozen portions, and a lower pressure is applied to the outer sides of the seals so that leaks in the seals themselves can be detected. Newly installed or old pipelines can be tested with the need for cutting, for the insertion of test manifolds, or subsequent rewelding.
