Why Attend
In-service welding continues to be an area in which there is much interest due to the need for repairs from corrosion damage as pipelines age and more branch connections are added to support open access and common carrier practices. Proper welding is needed to maintain service, avoid loss of contents and avoid venting methane. DNV’s six-hour In-Service Welding course covers:
✓ Factors affecting burnthrough including wall thickness, welding parameters and flow rate/pressure; how to avoid burnthrough and related concerns
✓ Common factors and requirements in hydrogen cracking and preventive measures
✓ Types of full-encirclement sleeves, their design and fabrication, as well as how to assure effective reinforcement
✓ The concept and history of weld deposition repair, the risks and practical applications
✓ Branch connection designs, reinforcement types, pressure testing and hot tapping through welds
✓ Code and regulatory requirements
✓ Lessons learned from previous incidents, both reported and unreported, as well as the 10 commandments of in-service welding
