Pipeline Repair, Hot Tapping & In-Service Welding

Date & Time: 23 Oct 2018 08:30 AM
Location: Rydges World Square, 389 Pitt Street Sydney

This course provides an in-depth overview of the various aspects of pipeline modification and repair (full encirclement sleeves, hot taps etc) and to address the concerns associated with welding of in-service pipelines.

A thorough understanding of the factors that affect welding onto in-service pipelines helps avoid pipeline shutdowns and interruptions of service, thereby bolstering both economic and environmental benefits for operators and welders alike. Plus, repairs can be undertaken efficiently, effectively and with full confidence.

Pipeline welding
The course includes a review and critical analysis of available thermal analysis models, including the original Battelle model, the heat sink capacity method and the PRCI thermal model for Hot Tap Welding.

Course attendees will learn why these models, while useful as planning tools, should not be regarded as ‘magic bullets’ against hydrogen cracking in hot tap welding by utilising comparative examples.

This course will give an unbiased analysis of the best strategies for avoiding burn through and the development of crack susceptible weld microstructures. It will also cover the latest defect assessment methods for pipeline engineers and managers, from simple, quick assessments through to more detailed ‘fitness for purpose’ analysis.

The course will dispel a number of misconceptions that have developed pertaining to operating practices required to safely weld onto an in-service pipeline.

It will demonstrate that the application of industry best practices for pipeline repair, hot tapping and in-service welding can help:

  • Ensure the safety of workers
  • Reduce the probability of a shutdown, failure or service interruption
  • Extend the life-cycle of pipeline systems
