What conditions should be met when setting the fixed support:

  The fixed support is mainly used where wired displacement and angular displacement are not allowed
The pipeline between the two fixed supports shall be in a straight line and no corner is allowed; The interval between two adjacent fixed supports shall be determined according to the selected compensation method and can bear the thrust of the pipeline
Only one compensator can be set between the two fixed supports, and its compensation capacity shall meet the thermal elongation of the pipe section
The compensator is set close to the fixed support, and its interval can be determined according to the rigidity and strength conditions of the pipeline, The judgment principle of interval is suitable for bearing the thrust of pipeline due to thermal expansion and cold contraction
Therefore, the support and foundation shall be firm and able to bear the thrust The setting of fixed support shall meet the following requirements: , 1
For more complex pipeline works, fixed supports can be used to divide the pipeline into multiple pipe sections with simple shapes (such as L-shape or U-shape, etc
) 2
Adopt & PI; Shape compensation shall be set in the middle of two fixed points (not every & PI; bend is a fixed point) 3
Fixed points shall be set at places where pipeline vibration and pulse are to be borne and near places where branch pipeline displacement is controlled, such as branch pipe led out from main pipe of pipe gallery 4
Fixed supports shall be set at the dividing points of pipelines entering and leaving the unit area Natural gas support http://www
