What are the cause of the pressure vessel explosion
Working under pressure explosion: container original bearing capacity to use under the pressure of explosion. The overpressure explosion caused by safety relief devices void automatically. Working under pressure explosion caused by container body defect and performance degradation. The overpressure overtemperature 2. Pressure vessels with congenital defects 3. Not according to stipulations to carry out regular inspection of pressure vessels and scrap. 4. Corrosion and container corrosion in pressure vessel 5. Unsmooth relief valve, regular check, not according to stipulations displacement is not enough. 6. The operator peccancy operation 7. Pressure vessel with the material at the same time into the reaction and explode.
Overpressure explosion: use explosion pressure rated pressure more than container capacity.
Bang "refers to the extremely rapid physical or chemical energy release process. Pressure vessel rupture can be divided into physical explosion and chemical explosion phenomenon. The so-called physical explosion phenomenon is container high pressure gas rapid expansion and internal energy released at high speed. Chemical explosion phenomenon and energy release of the chemical reaction speed, its explosion hazard degree than physical explosion phenomenon is serious.
