Plastic pipes should be protected against long-term sunlight. Plastic pipes have poor UV resistance and are prone to aging under long-term direct sunlight. Therefore, in the design, construction and engineering acceptance, protective techniques and methods must be adopted to ensure the safety of the pipeline system and extend its design life. This is not necessary in the use of traditional pipes. The technical priority to solve this problem should be: natural compensation-fixed bracket-natural compensation fixed bracket-compensator. And the fixed bracket must maintain a certain surface contact with the pipeline, not a line contact.
The connection method of the pipeline improves the safety of the pipeline system. The plastic pipeline not only inherits the simple connection methods in traditional pipelines, such as screw connection and flange connection; at the same time, it also creates some new connection methods, such as hot melt and electrofusion Connection, snap ring, card sleeve type connection, etc.
Especially when the hot melt connection is used in indoor and outdoor pipelines, it greatly improves the safety of the pipeline system. It has both good integrity and flexibility against deformation caused by external forces. According to the earthquake damage analysis of the Haicheng and Tangshan earthquakes in China, the traditional feedwater cast iron pipe was damaged during the earthquake and 95% of the fracture occurred at the interface. The use of plastic pipes greatly improves the safety of the piping system.
New pipe fittings have changed the design concept. With the application of plastic pipes, some new pipe fittings have appeared. For example, the special fittings for plastic pipes used in building water supply-water separators. The application of the water divider eliminates the need for intermediate fittings, and it can give full play to the characteristics of the plastic pipe system with low resistance loss.
