Title Guidelines to good practice in pipe freezing
Bibliographic information Department of Mechanical Engineering, University of Southampton, Southampton S09 5NH, United Kingdom, July 1991. 109p. Illus. 32 ref.
Abstract 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.
