Description

Clamping unit for pipes with improved strength The present invention relates to a pipe clamping device with improved strength, and more specifically, to a pipe clamping device with improved strength that can withstand deformation caused by pipe flow or external forces for a long time by significantly improving strength, while being easy to manufacture and minimizing the increase in manufacturing costs. Pipelines for transporting specific gases or fluids are used by connecting multiple pipes together depending on the site conditions. Various methods, such as welding connection methods, are used to connect multiple pipes together. Among them, if we look at the non-welding connection method, two pipes are arranged in a line, and then a ring clamp is fastened between the two pipes to connect and fix the two pipes. Since these ring clamps have complex shapes, such as curved shapes and bent regions, they are typically manufactured using aluminum, which has high machinability. However, due to the characteristics of piping through which gas or fluid passes, continuous flow occurs at the connection points due to twisting and shaking between pipes. Given the material properties of highly ductile aluminum, deformation occurs in the contact area with the pipes due to this continuous flow, and there was a problem in that fluid or gas leaked to the outside as a result of this deformation. Accordingly, Korean Registered Patent No. 1134992 sought to prevent fluid or gas leakage caused by deformation by forming a thicker portion of one side of the clamp that corresponds to the contact area with the pipe. However, the pipe clamp according to Korean Registered Patent No. 1134992 only had the effect of delaying deformation, and had limitations in responding to situations where fluid or gas leaked even after repeated flow in the pipe for a long time, as the contact area deformed. Meanwhile, some have attempted to manufacture clamps using high-strength stainless steel; however, stainless steel has low workability, which not only lowers productivity but also significantly increases manufacturing costs.
