| 3、 Calculation of Bearing Force for Axial External Pressure Ripple Compensator: (Without Considering Temperature Correction of Compensation Amount and Stiffness) |
| |
Example: One carbon steel pipeline with a nominal diameter of 500mm and a working pressure of 0.6MPa; The medium temperature is 350 ° C, the minimum ambient temperature is -10 ° C, the installation temperature is 20 ° C, the pipeline length is as shown in the diagram, and the fatigue failure frequency is required to be 3000 times. To install an external pressure compensator, calculate the force exerted by the compensator on the support.
The general installation position of the external pressure compensator is as follows (as shown in the diagram): |
|
|
Solution: (1) Thermal deformation calculation: △ L=a · t · L=0.0133 × 360 × 30=143.6mm
(2) According to the usage conditions and thermal deformation calculation data, 0.6TWY500 × 8F, N=3000 times can be selected for sample inspection,
X0=192mm Kx=272N/mm。 (Without pre deformation)
(3) A and B pipe supports are subjected to axial force:
Internal pressure thrust: Fp=100 · P · A=100 × 0.6 × 3167=190020N
Axial elasticity: Fx=Kx · X \ \ 272 × 143.6=39059.2N
Fz=Fp+Fx=190020+39059.2=229079N |
