PHMSA Advisory on Weldable Compression Couplings


The Pipeline and Hazardous Materials Safety Administration (PHMSA) recently issued Advisory Bulletin ADB-09-02 to the owners and operators of hazardous liquid and natural gas pipelines regarding weldable compression couplings. The background statement in the introduction to the advisory is rather lengthy, and describes numerous factors related to a specific incident in 2007 that resulted in 2 fatalities.

Advisory: PHMSA advises operators of hazardous liquid and natural gas pipelines installing or planning to install weldable compression couplings and similar repair devices to follow manufacturer procedures to ensure correct installation. In addition, PHMSA also advises these operators to follow the appropriate safety and start-up procedures to ensure the safety of personnel and property and protect the environment. The failure to install a weldable compression coupling correctly, or the failure to implement and follow appropriate safety and start-up procedures, could result in a catastrophic pipeline failure. PHMSA strongly urges operators to review, and incorporate where appropriate into operators’ written procedures, the manufacturer’s installation procedures and any other necessary safety measures for safe and reliable operation of pipeline systems.
