Main principles of circumvention in pipeline construction
1. Small tubes avoid large tubes: Small tubes are easy to bend and low in cost. 2. The branch pipe avoids the main pipe: The branch pipe generally has a smaller pipe diameter, and the influence scope and importance of the branch pipe are less than the main pipe. 3. Pressured tubes avoid pressureless tubes (pressure flow tubes avoid gravity flow tubes): The gradient and flow direction of pressureless tubes (gravity flow tubes) change, which has a greater impact on the flow. 4. The water supply pipe avoids the drain pipe: In addition to the reason mentioned above, the drain pipe usually has a large diameter and many impurities in the water. 5. Normal temperature pipes avoid high (low) temperature pipes (cold water pipes avoid hot water pipes, non-insulated pipes avoid heat insulation pipes): The temperature of the pipe is higher than...
