What is the steel hoop of water supply PE pipe-Yuhong Industry

The ring ratio of PE water supply pipe actually refers to the external pressure index. The load of pressure pipeline includes internal pressure and external pressure. The stress caused by internal pressure is usually the main factor that causes the damage of PE pipeline. The failure forms are excessive deformation and fracture caused by tensile stress on the pipe wall (plastic pipes are usually caused by creep). This design is generally based on internal pressure load, material selection and structural data (such as wall thickness, etc.). ) in the design calculation, and then consider the external pressure load for design verification, modify the structural data when necessary. The ring stiffness of PE pipe is actually not constant.

For example, de 1 10*0.8 MPa PE pipe.

Ring stiffness refers to the ability of pipes made of polymer composite materials to resist external pressure load (such as pe water supply pipes, PVC-U water supply pipes, steel belt PE pipes, etc.). ), called hoop bending stiffness, is a method to measure the ability of pipeline to resist hoop deformation. Test method or calculation method can be used.

The ring stiffness of PE pipe is actually not constant.

For example, PE pipes of DE1/KLOC-0 * 0.8 MPa and de3 15*0.8 MPa are also 8 kg pressure pipes, but it does not mean that they will be 8sn, that is, the ring stiffness of 8 N.. The larger the pipe diameter, the lower the ring stiffness. In another case, the change of temperature will also be affected. When the weather temperature decreases, the hardness of PE pipe increases. The stiffness of that natural re will also increase.
