time2025/08/06
- Tianjin Youfa Pipeline Technology's Jiangsu Branch facility boasts full-spec spiral steel pipes (φ219–φ4220mm), including industry-leading φ4220mm diameter pipes and 36m extra-long piles, with diversified anti-corrosion options (3PE, epoxy, etc.). Advanced automation, 20m full-length NDT (X-ray/ultrasonic), and X70-grade material compatibility ensure premium quality.
In the booming trend of the pipeline industry, relying on the mature foundation of Jiangsu Youfa Steel Pipe Co., Ltd., Tianjin Youfa Pipeline Technology Co., Ltd. Jiangsu Branch has emerged. After careful preparation and efficient construction, the installation progress of the main equipment in the base has reached 90%, and it is expected to be officially tested on August 12, 2025. This milestone not only marks a key milestone for Youfa Pipeline Technology in the national layout of spiral steel pipes and anti-corrosion steel pipes, but also strengthens the collaborative linkage between the North China and East China markets, providing closer services to customers across the country.
