Additional Requirements for High Pressure Pipelines
All Utility Installation Request forms for high pressure pipelines
(generally 60 psi or greater) should contain the following additional
information in the description section of the permit form:
- diameter
- wall thickness
- material specification
- minimum yield strength
- maximum operation pressure of the pipeline.
With the exception of the maximum operation pressure of the
pipeline, this information is to be supplied for both the carrier
pipe and the casing. Assurance must also be given that the installation material
and design meet the minimum federal safety standards for liquid
and gas pipelines
.
High pressure pipeline requests, cased and unencased, will
require the following project information:
- depth of cover
- accurate GPS location
- roadway crossing angle
- display of pipeline markers
- display of vent stacks (cased only)
- cathodic protection (unencased only)
- signed and sealed Barlow's equation (unencased only)
