1. Carbon steel pipelines require stress-relief heat treatment； 2. The bypass line should be isolated using insulation blocks to prevent localized overheating ； 3. Welding is strictly prohibited outside the weld area; if welding must be carried out, stress-relief heat treatment shall be performed ； 4. Practice civilized construction to avoid collisions and prevent local stress concentration, which could lead to stress corrosion.
