The pipe is not easy to rust, has good hydraulic performance and is suitable for fire water supply systems. Many developed countries allow the use of plastic pipes, such as PVC-C pipes, in some locations, which are light, easy to install and long in service life, but which have poor mechanical and fire-resistant properties, with clear requirements for installation location and installation form.
