17 Avoidance Principles in Pipeline Construction

DATE:2020-04-07
1. Small tube makes big tube: small tube is easy to bend and low cost.
2. The branch pipe makes the main pipe: the branch pipe generally has a smaller pipe diameter. For reasons for avoidance, see Article 1. Another point is that the influence scope and importance of the branch pipe are not as good as the main pipe.
3. The pressure tube allows the pressureless tube (the pressure flow tube allows the gravity flow tube): the pressureless tube (or gravity flow tube) changes the slope and flow direction, and has a greater impact on the flow.

4. The water supply pipe allows 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 tube allows high (low) temperature tube (cold water tube allows hot water tube, non-insulation tube allows insulation tube): above normal temperature, consider exhaust; below normal temperature, consider anti-condensation insulation.
6. Low-pressure pipes make high-pressure pipes: high-pressure pipes have high cost and high strength requirements.
7. The gas pipe makes the water pipe: the power consumption of the water flow is large.
8. Metal pipes make non-metal pipes: metal pipes are easy to bend, cut and connect.
9. Ventilation pipes for general pipes: Ventilation pipes are bulky and difficult to bend.
10. Small valve parts make many valve parts: consider factors such as installation, operation and maintenance.

11. Simple construction to avoid construction is difficult: This is considered from the aspect of avoiding increasing the difficulty of installation.
12. The small amount of engineering makes the large amount of engineering: This is considered from the aspect of avoiding increasing the amount of installation engineering.
13. Pipelines with low technical requirements make pipelines with high technical requirements: This is considered from the aspect of avoiding increasing the difficulty of technical requirements.
14. Convenient with fewer overhauls makes more overhauls and inconvenient: This is considered from the perspective of later maintenance.
15. Non-main pipelines avoid main pipelines: This is considered from the aspect of the importance of functions.
16. Temporary pipeline avoidance of permanent pipeline: This is considered from the aspect of pipeline service life.
17. Newly built pipelines avoid established pipelines: this is considered in terms of reducing cost, engineering volume and construction difficulty.
