Attention should be paid to the construction of metal corrugated culvert pipe

1. The length and corresponding position of the screw should be preset and processed attentively to ensure corresponding assembly.
2. Tightly closed waterproof should be considered.

3. Try to keep the flange position away from the location where the maximum equivalent stress and the maximum tangential stress are concentrated in the main path.
4. The maximum tangential stress to control the screw shear stress.
5. The density and size of the screw should be suitable for stress concentration caused by sedimentation of warpage.
6. Stress concentration caused by sedimentation of warp edge is used to control shear stress of screw.

Selection procedures for splicing metal bellows:

1. Implement reasonable preset and section of the pipeline, and confirm the way and number of using metal bellows for each section as appropriate.
2. Confirm the office pressure level.
3. Calculate the amount of repayment for each section of the pipeline, and confirm the amount of repayment for the fixed amount of the metal bellows.
4. According to the diameter, pressure level and repayment of the selection of metal bellows.
