The fixing structure for pipes and supports requires considerable attention
Thread Content
The figure below shows a insulated pipeline that has been opened for physical and chemical testing, along with the structure by which the pipeline is fixed to its supports. Primarily, the areas where the pipes come into contact with fasteners are separated using multiple layers of hard canvas; this serves to reduce vibrations, preventing the vibrations generated by the pipes from causing collisions and friction with the metal supports, thereby avoiding wear and corrosion. Are there any other functions?
Considering the effect of stresses generated by the thermal expansion and contraction of pipes on the supports also falls under the category of collision and friction
The main purpose is likely to avoid corrosion caused by the potential difference between different metals after contact; as for friction or fixation, other types of supports (such as U-shaped clamps) should be used
Another function is to provide insulation, thereby minimizing heat loss from the pipes; since both the metal brackets and the pipes are made of metal, the brackets act as heat sinks. Because a hot medium flows through this pipe.
