Whether air compressor and gas tank belong to special equipment

Whether air compressors and air storage tanks are special equipment depends on their specific specifications and working pressure.

For air compressors, in general, it itself is not directly regarded as special equipment. However, if the pressure vessels such as air tanks equipped with air compressors meet the definition of special equipment, then these pressure vessels need to be managed according to special equipment.

The gas tank may belong to special equipment, which mainly depends on its working pressure and volume. In China, according to the Special Equipment Safety Law and related regulations, special equipment usually refers to equipment that involves life safety and is more dangerous, including boilers, pressure vessels (including gas cylinders), pressure pipes, elevators, lifting machinery, Passenger ropeways, large amusement facilities and special motor vehicles in the field (factory). For a gas storage tank, if its design pressure is greater than or equal to 0.1MPa, its inner diameter is greater than or equal to 150mm, its volume is greater than or equal to 30L, or its inner diameter is greater than or equal to 150mm, and the product of working pressure and volume is greater than or equal to 2.5MPa · L, then it is regarded as special equipment and needs to comply with relevant safety technical specifications.

Therefore, it is necessary to judge whether the air compressor and the air storage tank belong to special equipment according to the specific situation. If the gas tank meets the definition of special equipment, it is necessary to carry out registration, regular inspection and use management in accordance with relevant regulations.
