The PU-C polyurethane epoxy ceramic composite spiral steel pipe for water supply is a spiral steel pipe manufactured by spiral seam submerged arc welding, shot blasting, rust removal, spraying(The inner wall adopts epoxy ceramic coating, and the outer wall adopts pipeline solvent-free polyurethane anti-corrosive coating), curing and other processes.

The length of a single section of PU-C composite steel pipe can be up to 12 meters. The construction is simple and convenient, with good sealing, strong bearing pressure and high mechanical strength. The pipe has a small excavation surface and low requirements for the foundation. Under special circumstances and when the groundwater level is high, welding on trenches can be used to improve engineering efficiency and reduce construction costs. The service life of PU-C composite steel pipe can reach more than 50 years.
