Many high temperature pipelines for transmitting gas or liquid have large internal temperature change, and according to the principle of expansion with heat and contraction with cold, the pipelines can deform along with the change of temperature and generate stress at the same time, so as to form additional load for the whole pipeline and the connected equipment. There are limitations based on the loads that the equipment, the pipe itself, or the supporting infrastructure can withstand, and therefore there are higher performance requirements for low friction resistance performance of the pipe racks at these locations when the system is designed. The current method is to use sliding friction support or roller support to reduce the displacement stress on the high temperature pipeline and reduce the friction force generated by the pipeline movement.

(2) the polytetrafluoroethylene material is not high temperature resistant and cannot be used in a high temperature environment;
(3) The bearing capacity of the polytetrafluoroethylene sliding sheet and the mirror surface stainless steel plate friction pair is only 10% -15% of that of steel, and in order to meet the vertical bearing capacity, the area of the polytetrafluoroethylene sliding sheet must be increased to reduce the stress of the polytetrafluoroethylene sliding sheet, so that the friction pair structure of the support is overlarge, and the horizontal slippage is restricted.
The roller (cylinder) support has a low friction coefficient, the theoretical friction coefficient is about 0.05-0.07, but the actual friction coefficient is far larger than the theoretical data due to the factors of roller (cylinder) surface corrosion, friction surface slipping, foreign object blocking and the like in the use process, and the roller blocking can occur under extreme working conditions, so that the adverse effect is achieved. In addition, the load area born by the roller (cylinder) friction pair is in line contact, the contact stress is large, and the roller friction is easy to rust in the use process if the roller friction is not designed with good external protection measures.
