Live Pipeline Plugging and Replacement for Shenmu-Anping Coalbed Methane (CBM) Pipeline Project

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.
