According to the difference in the position and purpose of use of the steel jacket steel steam insulation seamless steel pipe, three different types of brackets can be used for the steel jacket steel steam insulation seamless steel pipe: guide bracket, sliding bracket and fixed bracket.
Usually in places where the direction of the steam pipe elbow and bend is changed, a guide bracket will be used to fix the straight pipe section. The main function of the guide bracket is to prevent the working pipe from moving arbitrarily in the outer protective layer pipeline, so as to avoid the radial displacement of the working pipeline. It only allows the working steel pipe to expand freely along the axial direction of the pipe.
The function of the steel jacket steel steam insulation seamless steel pipe fixing bracket is to protect the corners, elbows and other components in the pipeline, balance the stress on the pipeline and prevent it from being transmitted. According to the structural form of the fixed bracket, it can withstand large axial forces, but it cannot resist radial shear forces. Therefore, when installing the bracket of the steel jacket steel steam insulation seamless steel pipe, it is necessary to reduce the radial shear force of the fixed bracket as much as possible, so as to withstand the axial force and ensure the safe use of the fixed bracket and the safety of the entire pipe network.
