Pipeline Safety: Weldable Compression Coupling Installation

Notice; Issuance of Advisory Bulletin.

The Pipeline and Hazardous Materials Safety Administration (PHMSA) reminds pipeline owners and operators of the importance of installing weldable compression couplings in accordance with manufacturer procedures and following appropriate safety and start-up procedures. The failure to install weldable compression couplings 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 take any other necessary safety measures for safe and reliable operation of pipeline systems.
