Hebei shengtian pipe-fitting group Co., ltd, a manufacturer of carbon steel bends, has a wide range of products: large simmer series, stainless steel series, carbon steel series, alloy steel series, anti-corrosion and thermal insulation series, galvanized plastic lining series, national standard non-standard and American Standard German standard, Russian standard and Japanese standard power plant power standard and marine chemical standard series.
Bend stretch bending is an advanced cold bending process. Its main characteristics are as follows: it can bend various profile sections, and almost all metal profiles and pipes such as aluminum, steel, stainless steel and copper can be made into bends.
Due to the cold work hardening of metal materials, the comprehensive mechanical properties of materials can be improved after tensile bending. Thus, a definite calculation model is formed to calculate the fluid pressure of the fluid at the inner wall of the pipe according to the population velocity and the pressure of the population. After the fluid adopts the non slip flow star at the pipe wall, the pressure from the fluid acting on the inner wall of the elbow is calculated. The stress of the elbow, that is, the fluid, consists of two parts. The first part is the isotropic component independent of viscosity, that is, the fluid pressure; The second part is the components related to viscosity.
The fluid in the pipe is incompressible, and the change of fluid body secret is small. Here, only the change of fluid shape is discussed to analyze the viscous stress of the fluid in the elbow and study the mean value of a section of the elbow.
