Few evaluations have included repairing pipelines with circumferential stress-corrosion cracking (CSCC) or girth welds defects subjected to slope and ground movement.
The JIP is addressing this gap. The current focus is on medium line sizes (NPS 12 to 24) and straight pipe geometries.
However, there is also interest in other end applications, such as:
- small line sizes (NPS 2 to 8),
- large line sizes (NPS 30 to 48),
- loading conditions such as external bending with internal pressure, and
- complex geometries such as bent pipes, elbows or tees.
