The fire-fighting pipeline is an important component of fire-fighting facilities of civil buildings and industrial and mining enterprises. In the fire water supply system, a certain pressure is needed to be borne, so that a galvanized steel pipe or a steel wire skeleton polyethylene composite pipe is adopted for the main road. 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.
The galvanized steel pipe has good pressure bearing performance, but the conditions of rust, scaling and blocking of the pipe clamp joint often occur in the use process, so that the water leakage phenomenon caused by the corrosion of the pipe joint is aggravated. At present, the prior galvanized pipe is connected by adopting a groove clamp type, but the galvanized layer can be damaged by the groove in the rolling process, so that the wall thickness of the pipe at the position is thinned, and the corrosion of the pipeline is accelerated. Meanwhile, the corrosion degree of the inner layer of the pipe is not easy to find and maintain after the pipe is used for a long time. The composite steel pipe coated with the epoxy resin inside and outside adopts modified anti-corrosion epoxy resin powder, and is resistant to chemical corrosion, but the resin powder bubbles at a welding part or a certain part of a pipe are also fallen off to cause corrosion, especially in environments with bad water quality, or the coating is easy to separate under long-term corrosion of water to cause anti-corrosion failure. .
