Special equipment inspection

Safety inspection for special equipment includes statutory inspection of mechanical and electrical products and statutory inspection of pressure classes. Statutory inspection of pressure classes includes boiler inspection, pressure vessel inspection, pressure piping inspection, safety valve calibration and boiler medium testing.
1. Boilers and pressure bearing special equipment shall be designed as a pressure steam boiler with a normal water level greater than or equal to 30L, and the rated steam pressure greater than or equal to 0.1MPa (gauge pressure); a pressurized hot water boiler with outlet water pressure greater than or equal to 0.1MPa (gauge pressure) and rated power greater than or equal to 0.1MW; an organic heat carrier with rated power greater than or equal to 0.1MW. Boiler. Its statutory inspection includes boiler installation supervision and inspection and boiler regular inspection two kinds, including boiler regular inspection including boiler external inspection, boiler internal inspection and boiler pressure test three kinds.
Two, pressure vessels, pressure special equipment, the scope of the maximum pressure is greater than or equal to 0.1MPa (gauge pressure) of the gas, liquefied gas and the highest working temperature is higher than or equal to the standard boiling point of the liquid, the volume is greater than or equal to 30L, and the internal diameter (non-circular cross-section of the maximum internal boundary geometry) is greater than or equal to 150mm fixed container and mobile capacity. It is known that the working pressure is greater than or equal to 0.2MPa (gauge pressure), and the product of pressure and volume is greater than or equal to 1.0MPa L gas, liquefied gas and standard boiling point is equal to or lower than 60 degrees of liquid cylinder; oxygen chamber. Pressure vessel inspection includes pressure vessel installation supervision and inspection and pressure vessel regular inspection two kinds, including pressure vessel regular inspection including pressure vessel comprehensive inspection and pressure vessel annual inspection.
Three, pressure piping, pressure type special equipment, the scope of the maximum pressure is greater than or equal to 0.1MPa (gauge pressure), the medium is gas, liquefied gas, steam or flammable, explosive, toxic, corrosive, the highest working temperature is higher than or equal to the standard boiling point of the liquid, and the nominal diameter is greater than or equal to 50mm pipe. The pipes with the nominal diameter less than 150mm and the highest working pressure less than 1.6MPa (gauge pressure) are non-toxic, non flammable and non corrosive gases. The statutory inspection of pressure piping is applicable to the pipeline and auxiliary facilities in the above scope, including two kinds of pressure piping installation supervision and inspection and pressure pipeline regular inspection, including pressure piping regular inspection including pressure piping comprehensive inspection and pressure pipeline on-line inspection.
