管支架 Tube bracket
管道支承的一种结构件，它作为管道的支撑结构，根据管道的运转性能和布置要求，管架分成固定和活动两种。设置固定点的地方成为固定支架，这种管架与管道支架不能发生相对位移，而且，固定管架受力后的变形与管道补偿器的变形值相比，应当很小，因为管架要具有足够的刚度。设置中间支撑的地方采用活动管架，管道与管架之间允许产生相对位移，不约束管道的热变形。
Tube bracket
A structure of pipe support structure, which acts as a pipe support structure, according to the pipeline performance and layout requirements, pipe rack is divided into fixed and movable two. The place where the fixed point is set becomes the fixed support. The relative displacement between the pipe support and the pipe support can not occur. Moreover, the deformation of the fixed support after the stress should be small compared with the deformation value of the pipe compensator because the pipe support should have Sufficient rigidity. Set the middle of the support place active pipe rack, pipe and pipe rack to allow relative displacement between, do not constrain the pipe thermal deformation.
