Pipe Freezing
Pipe freezing is method to freeze the content of a section of pipe by applying cryogenic (i.e. very low temperature) freezing agent in a controlled manner. When the ice plugs are formed maturely, maintenance works to the pipe can be carried out between the ice plug without draining massive amount of pipe fluid. This technique has been used on cross-country pipeline, process plants and pipelines containing water, sewage and a wide range of oils and other fluids.
