Taitat Changlin Pipeline Technology (Jiangxi) Co., Ltd. (TTCL) has successfully completed a DN200 cylindrical double plugging operation, providing a safe and efficient solution for maintenance work on an operating natural gas pipeline.
During this project, TTCL applied its advanced line stopping technology to perform a DN200 double plugging operation under live pipeline conditions. The pipeline was designed for a pressure of 1.6 MPa, with an actual operating pressure of 0.8 MPa, and the transported medium was natural gas.
The successful completion of this operation demonstrates TTCL’s professional capabilities in pressurized natural gas pipeline maintenance. Through precise engineering design, reliable plugging equipment, and strict operational procedures, the project was completed safely while maintaining continuous gas supply and minimizing the impact on downstream users.
TTCL’s cylindrical double plugging system provides an effective solution for pipeline isolation, allowing operators to safely carry out pipeline modification, valve replacement, maintenance, and emergency repair activities without shutting down the entire pipeline system.
With extensive experience in hot tapping and line stopping technology, TTCL provides comprehensive pipeline maintenance solutions for natural gas, water, oil, and industrial pipeline networks. The successful completion of this DN200 double plugging project further highlights TTCL’s expertise in ensuring safe, efficient, and uninterrupted pipeline operations.
For more than 40 years, TTCL has been dedicated to the research, development, manufacturing, and application of hot tapping machines, line stopping equipment, PE pipeline tools, and pipeline repair solutions. TTCL continues to support global customers with innovative technologies and reliable services.
