Abstract

Traditional rehabilitation of natural gas pipelines often relies on large-scale excavation, which causes significant traffic disruption and notable environmental impact. As an efficient alternative, trenchless cured-in-place pipe (CIPP) lining technology can substantially reduce interference with surface activities. This paper focuses on a specific natural gas pipeline rehabilitation project to investigate the design and construction practices of CIPP lining technology. Through systematic engineering design, including the composite liner structure and wall thickness, key construction control parameters such as inversion speed, curing pressure, and temperature were determined. Engineering practice demonstrates that this technique offers strong adaptability, short construction duration, minimal environmental impact, and reliable rehabilitation quality, highlighting its broad potential for application in natural gas pipeline repair. To further enhance the adoption of this technology, future efforts should focus on refining relevant technical standards and material systems to promote its standardized and large-scale development.
