After each earthquake, it was found that during the earthquake, the storage tank and its connected pipeline were displaced, and then a lot of stress occurred, which caused the pipeline and the connected equipment, pipe fittings, fixed supports, etc. to bear excessive forces and moments. At this time, the tank body may be damaged, and the liquid leakage accident may occur. In order to increase the stress and overcome the damage in the above manner, the pipeline must be carefully planned to have sufficient flexibility. The stainless steel bellows hose has sufficient flexibility. It can reduce the stress in the pipeline, increase the thrust of the pipeline to the storage tank and the support, and then protect the storage tank.
- Assuming the mission of temporarily replacing hot and cold steel materials, under the effect of thermal stress caused by temperature changes, huge cracks will occur from time to time, and they will start to break. Therefore, the structure and pipeline under the mission condition of changing the temperature should consider the thermal exhaustion of steel.
- Under the effect of low temperature, cementite in carbon steel will migrate and gather because of the energy obtained, forming coarse-grained cementite and intercalated in ferrite, its carburizing collar will gradually change from flaky to spherical , Called spheroidization. Because the graphite strength is extremely low and appears in the form of flakes, the strength of the material is greatly reduced and the brittleness is increased, which is called the graphitization of the material. Temporary mission of carbon steel in the environment above 425 ℃, graphitization will occur, more clearly above 475 ℃. The high operating temperature of SH3059 regular carbon steel is 425℃, while the high operating temperature of GB150 regular carbon steel is 450℃.
