Background
The pipeline bracket is a structural member for overhead laying pipeline support on the ground. The device comprises a fixed bracket, a sliding bracket, a guide bracket, a rolling bracket and the like. Pipe brackets are used wherever there is a pipe running, also known as pipe supports, pipe sections, etc. As a supporting structure of the pipeline, the pipe rack is divided into a fixed pipe rack and a movable pipe rack according to the running performance and arrangement requirements of the pipeline. Where the fixing points are provided as fixing brackets, the pipe and the pipe brackets cannot be displaced relatively, and the deformation of the pipe frame after being stressed should be small compared with the deformation value of the pipe compensator because the pipe frame has enough rigidity. The movable pipe frame is adopted in the place where the middle support is arranged, the relative displacement is allowed to be generated between the pipeline and the pipe frame, and the thermal deformation of the pipeline is not restrained.
In the pipeline connection construction site, the pipeline is connected with the pipeline and the pipeline is connected with the pipe fitting, and the pipeline and the pipe fitting are required to be placed stably so as to be convenient for assembly and welding.
