Project Overview
In September 2021, inline inspection (ILI) of the Xingxian Gas (CBM) Utilization Project and Yuanping Second Gas Source Connection Project revealed critical deformations requiring pipe replacement:
- 13% OD deformation at 12,189.156m
- 11.8% OD deformation at 46,632.817m
- 11.3% OD deformation at 13,012.803m
This non-stop pipeline isolation solution ensures continuous CBM supply during repairs.
