In December 2021, the project “Design and Equipment for Trenchless Lining Repair Materials for Gas Pipelines,” in which our company played a significant role in R&D, was successfully awarded the “Outstanding Scientific and Technological Achievement Award” after evaluation by relevant authoritative institutions. This accolade not only signifies high recognition of the project's technological innovation and practical application value but also fully affirms our company's R&D capabilities and commitment to responsibility in the field of trenchless gas pipeline rehabilitation. It adds another significant honor to our company's technological innovation and development.
In recent years, the aging of urban gas pipeline networks has become increasingly prominent. Hazards such as pipeline corrosion, damage, and leaks not only affect the stable operation of gas supply systems but also threaten public life and property safety. Traditional gas pipeline repair methods primarily rely on excavation, which suffers from numerous drawbacks including lengthy construction periods, severe disruption to residents, damage to the urban environment, and high costs. These limitations make it difficult to meet pipeline operation and maintenance needs in sensitive areas such as urban core zones, historic districts, and transportation hubs. Consequently, the development of efficient, environmentally friendly, and safe trenchless repair technologies has become an urgent industry need.
The “Design and Equipment for Trenchless Lining Repair Materials for Gas Pipelines” project addresses these industry pain points by focusing on core challenges in trenchless repair. It concentrates on two key objectives: optimizing the performance of lining repair materials and developing compatible equipment. As a participating entity, our company leveraged its technical strengths by establishing a specialized R&D team. We deeply engaged in the formulation design and performance testing of relining materials, alongside structural optimization and operational enhancement of supporting construction equipment, contributing to the project's technological breakthroughs.
The developed relining materials exhibit high strength, corrosion resistance, excellent sealing properties, and excellent flexibility. It can precisely adapt to gas pipelines of various diameters. Without excavation, the relining process enables the material to tightly bond with the existing pipeline, forming a robust protective liner. This effectively seals corrosion points and damaged areas, eliminating leakage risks at their source while enhancing the pipeline's pressure resistance and service life, achieving a “restorative upgrade.” The accompanying construction equipment optimizes the relining operation process, improving construction efficiency and precision while reducing labor intensity for workers. It adapts to complex geological conditions and construction scenarios, achieving industry-leading single-repair lengths and construction stability, thereby breaking the application limitations of traditional trenchless repair technologies.
The selection for the “Outstanding Scientific Achievement Award” rigorously evaluated core dimensions including technological innovation, industry leadership, practical application value, and economic benefits. This project stood out through dual innovations in materials and equipment, alongside its significant advancement of the gas pipeline trenchless repair industry. The project's implementation has not only effectively reduced gas pipeline operation and maintenance costs while minimizing construction disruptions to urban traffic and the environment, but also accelerated the adoption and advancement of trenchless repair technology. It provides reliable technical support for the safe operation and maintenance of urban gas pipeline networks, delivering significant social benefits and industry value.
