The tests and verifications commonly considered in PE pipelines are for hydraulic testing of pipelines, and the load of all underground pipelines must be considered. PE water pipes are no exception. Let's take a look together.
Loads are external forces and other factors that cause internal forces and deformation of structures or components. Or, by convention, apply various direct effects to an engineering structure to create an engineering structure or component effect. Typical structural weight, floor active load, roof active load, roof area gray load, vehicle load, crane load, equipment natural load (such as wind, snow, ice and waves) and dynamic load.
In theory and design experience, because the PE water supply pipe itself has high pressure requirements and high material requirements, the national standard of the industry does not compulsively test the ring stiffness of the water supply pipeline, so its ring stiffness should be greater than the same wall thickness of the sewage. tube. Therefore, if the waterline is overloaded, it should be sleeved to protect it from excessive external forces. If you cross the sidewalk and other no-load roads, you will not be affected. The burial depth cannot exceed 0.8 meters, taking into account the northern frost line.
