QINGYUAN PIPE TECH
QINGYUAN PIPE TECH
Founded in 2003, we are a national high‑tech enterprise with our manufacturing base located in Shanghai.
We deliver complete sets of technology and equipment for MSW mechanical spiral‑wound lining trenchless pipeline rehabilitation. This technology creates a reinforced pipe‑in‑pipe liner within existing aging pipelines.
Suitable for pipeline diameters from DN1000 to DN5000, it enables in‑water construction without massive excavation, realizing highly‑efficient pipeline renewal.
We independently research, develop and manufacture construction equipment, lining profiles and large‑diameter HDPE pipes. Backed by our proprietary patented technologies, we welcome export business, project partnerships and global agency cooperation.
