||Guidelines to good practice in pipe freezing
||Department of Mechanical Engineering, University of Southampton, Southampton S09 5NH, United Kingdom, July 1991. 109p. Illus. 32 ref.
||Cryogenic pipe freezing is a technique for solidifying the liquid in a pipe to form pressure-resistant plugs for maintenance and repair work. Part 1 of these guidelines provides an introduction to the concepts of pipe freezing and outlines the points to be considered when deciding whether the technique would be suitable for a particular application. Part 2 sets out the information needed to determine the conditions under which a plug may be formed by pipe freezing. Topics covered include: freezing water-based, hydrocarbon-based and other fluids; special freezing techniques; characteristics of pipe wall materials; safe handling of cryogenic fluids and solids; operating procedures; special requirements for particular industries.
