Damage that might occur due to the elements of nature or human activity. Steel Casing Pipe is used in different types of horizontal underground boring, where the pipe is jacked into an augered hole in segments and then connected together by welding or by threaded and coupled ends, or other proprietary pipe connectors. The Steel casing pipe can also be set up and welded into a "ribbon" and then directionally pulled through a previously drilled hole under highways, railroads, lakes & rivers.
Steel Casing Pipe protects one or many of various types of utilities such as watermains, natural gaslines, electrical high voltage lines, fiber optic communication lines, etc. The utility lines that are run through the Steel Casing Pipe are most commonly mounted and spaced within the Steel Casing Pipe by using "casing spacers" that are made of various materials, including stainless or carbon steel and the more economical plastic versions.
The ends of a Steel Casing Pipe "run" are normally sealed with "casing end seals", which can be of the "pull-on" or "wrap-around" rubber varieties. Steel Casing Pipe generally has no specific specifications, other than the need for the material to be extremely straight and round. In some areas A.S.T.M. specifications may be required by project engineers. The specification most commonly called for is A.S.T.M. 139 Grade B. This specification gives parameters for minimum yield and tensile strengths of the steel pipe being used for casing, and tolerances of straightness and concentricity.
