General

Steel casings are used to install and maintain pipeline crossings such as those at road and railroad right-of-ways. This standard details acceptable practices for the design, fabrication, installation, maintenance, and monitoring of steel-cased pipelines.

The use of cased crossings should take into account load considerations, unstable soil conditions, protection from third-party damage, sound engineering practices, and regulatory requirements.

This standard does not imply that utilization of casings is mandatory or necessary.

This standard does not imply that cased crossings, whether electrically isolated or electrically shorted, contribute to corrosion of a carrier pipe within a cased crossing. However, cased crossings may adversely affect the integrity of the carrier pipe by shielding cathodic protection (CP) current to the pipe or reducing the CP effectiveness on the pipe in the vicinity of the casing, including if the casing is coated and electrolytic contact exists between the casing and carrier pipe (see Paragraph 3.2.3 in Casing Design).

The practices contained in this standard may or may not be applicable to casings installed prior to its issuance. It is presumed that all practices described in this standard are performed in a safe manner.
