Abstract
- The gas pipelines usually undergo complicated and changeable regional environment. As the level of the potential difference or pipeline’s route changes in the space and therefore elastic bending cannot meet the needs when pipe changes its direction, we generally use pipe bend to connect two pipelines with different spatial extend direction during the pipe laying period, and it can reduce the temperature stress. Unreasonable design of elbow will lead to pipeline damage. We established mountain area pipeline model, and conducted analysis on pipeline stress under different elbow angles. Research shows that different angles of the bends suffer different operation stress, and we have come to the conclusion that the angle of pipe bends should not be within the range of 15 degrees to 35 degrees.
