PIPELINE SAFETY REGULATORY INTERPRETATION
Note: A pipeline safety regulatory interpretation applies a particular rule to a particular set of facts and circumstances, and, as such, may be relied upon only by those persons to whom the interpretation is specifically addressed.
SECTION: §195.208
SUBJECT: Welding of supports and braces.
FACTS: As given in letter February 15, 1980, from Mr. Don C. Ellis, Williams Brothers Engineering Company.
"In the design of a 16-inch oil pipeline in the Kuparuk Field, Alaska, for ARCO Oil and Gas Company, we have utilized sleeves welded to the line pipe for attachment of support saddles at anchor points."
"The procedure we are proposing involves placing halfshell sleeves around the line pipe circumference, attaching the sleeves via a fillet weld, and then affixing the anchor support to the sleeve thereby eliminating any support member being welded directly to the line pipe."
Question: Does the proposed method of attaching anchor supports to sleeves encircling the pipeline comply with the requirements of Section 195.208?
Interpretation: Section 195.208 states: "Supports or braces may not be welded directly to pipe that will be operated at a pressure of more than 100 p.s.i.g." Because the proposed method of attaching supports does not include welding any support or brace to the pipe, the proposed method is in compliance with §195.208.
