Qingdao Taineng Silicon Valley DN200–325 / DN300–426 Branch Line Project Successfully Completed

The DN200-to-325 and DN300-to-426 branch line connection project in Qingdao Taineng Silicon Valley was successfully completed between November 23 and 24, 2025, achieving smooth, one-time completion and receiving positive feedback from the on-site client team.

This operation involved multiple branch-line connections conducted under live pipeline conditions using the encapsulation method. With varying pipe diameters, complex coordination, and stringent precision requirements, the project posed significant technical challenges. Despite the tight schedule and multiple work points, the project team ensured seamless progress through meticulous planning, strict adherence to safety procedures, and highly efficient execution.

During the operation, the on-site management team carried out detailed technical briefings and risk assessments in advance, ensuring that all safety and protection measures were firmly in place. Technical personnel performed accurate measurement, positioning, and connection work, while all team members coordinated efficiently to complete the project safely, smoothly, and with high quality within a short time frame.

The successful completion of this project enhances the operational capacity of the Qingdao Taineng Silicon Valley regional pipeline network and further demonstrates our company’s strong capabilities in live pipeline operations, branch line connections, and complex engineering scenarios.

Looking ahead, we remain committed to delivering high-standard, high-quality technical services, supporting gas network construction and upgrades across various regions, and providing clients with reliable solutions and professional engineering capabilities.
