Background

Typical vibrating pipes within the petrochemical industry include piping for moving equipment connections, two-phase flow piping, and the like, and vibration of the piping will cause fatigue failure or fretting of the piping components, which in turn leads to accidents such as leaks. According to statistics, about 10-15% of pipeline fatigue failures in the petrochemical industry are caused by vibration. Therefore, the vibration of the pipelines must be effectively controlled, and the damping pipe bracket is used as a structural member with low cost and good effect and plays a good role in controlling the vibration of the pipelines. The vibration reduction pipe support for the normal-temperature pipeline is mature in technology and structure, the pipeline is mostly fixed in a mode of clamping a flat steel U-shaped pipe and a bolt and nut assembly, and the vibration reduction pipe support does not have a vibration indication function.

Common high temperature or low temperature pipe support in the engineering because of pipeline high temperature or low excessively, in order to avoid pipeline heat or cold volume loss, do not allow the pipe strap direct with pipeline contact. The pipe support pipe bracket is wrapped by heat insulation materials, and a carbon steel pipe clamp is arranged outside the pipe support pipe bracket. This structural requirement renders conventional damping boots worthless. At present, two common low-temperature pipeline damping pipe holders are arranged on the site, one is that a steel pipe clamp is in contact with a pipeline, a cold insulation material is wrapped outside the steel pipe clamp, and the problem of cold leakage exists due to heat conduction of the pipe clamp. And the other method is to weld a pipe bracket stop block at the position close to the contact of the outer part of the low-temperature pipe bracket structure and the steel structure. Due to the fact that the construction difficulty is high, the interval between the stop block and the pipe support is large, and the vibration reduction effect cannot be achieved during operation. In addition, the integral casting pipe bracket has higher cost. Above-mentioned current conduit saddle does not possess the vibration instruction function all, consequently can not in time monitor the pipeline vibration condition, can only measure the vibration with the help of outside vibration testing arrangement, and some conduit saddles lead to unable realization vibration measurement because of the installation space restriction, and this makes the vibration real-time detection function of vibration pipeline become the blind spot.

CN203176551U discloses a heat-insulating shock-absorbing pipe bracket, which comprises a support frame, a bottom plate, a fixing plate, an annular heat-insulating layer and a pipe hoop, wherein the inner diameter of the heat-insulating layer is matched with the outer diameter of a pipeline, the pipe hoop is sleeved outside the heat-insulating layer, one end of the support frame is connected with the pipe hoop, the other end of the support frame is connected with the bottom plate, and the bottom plate can slide relative to the fixing plate; the heat preservation layer is made of aerogel. Adopt the splendid aerogel combined material of heat-proof quality to replace traditional heat preservation, realized the heat-proof quality and increased substantially, simultaneously because aerogel combined material has great porosity, except that assurance material self has good anti-seismic performance, can also greatly reduce the transmission of vibrations, make this conduit saddle possess antidetonation shock-absorbing function, reduced the vibration of pipeline, adapted to the cold and hot deformation of pipeline, satisfied the user demand on long distance high temperature material pipeline.

In view of this, how to provide a pipe bracket vibration damping support with a vibration indication function, which has a simple structure and a low cost, on the basis of not changing a structure required by pipe bracket heat insulation, ensures good contact between a pipe bracket bottom plate and the structure, and realizes pipeline vibration damping and indication of vibration amplitude becomes a technical problem to be solved urgently at present.
