Is the air compressor special equipment

Compressor dynamic equipment does not belong to special equipment, but as long as the working pressure of the gas storage tank and the connected pipeline is greater than or equal to 0.1Mpa, the volume and pipe diameter are greater than or equal to 25mm, it belongs to special equipment.

The oil and gas separator on the air compressor is as follows: volume: 0.063m & sup3;, design pressure: 1.57MPa, pressure test pressure: 1.97MPa, working medium: air and oil, temperature: 120 ℃.

Section 7.1.11 of the TSG21-2016 "Safety and Technical Supervision Regulations for Stationary Pressure Vessels" makes some special provisions for simple pressure vessels: simple pressure vessels do not need to be registered for use and do not need to be inspected regularly within the design period, but there is no mention of installation qualification and whether construction notification is required.

Provisions of Articles 2 and 3 of Supervision Regulation on Safety Technology of Stationary Pressure Vessels

for the air compressor system, it can be briefly considered as "the design pressure is less than or equal to 1.6MPa, the volume is less than or equal to 1000L, the product of working pressure and container is greater than or equal to 2.5MPa.L, and is less than or equal to 1000MPa.L".

That is to say, in the compressed air system for general use, if the air storage tank is less than 1 cubic meter or 10kg, or if the pressure is higher than 10kg and lower than 16kg, the capacity is less than 1 cubic meter and the product of pressure and volume (unit L) is less than 1000, it is a simple pressure vessel.

The oil and gas barrel and cooler cylinder in the air compressor body; the filter tank body; the dryer cylinder body, etc. basically will not exceed the scope of "simple pressure vessel. This is mainly because the simple pressure vessel is easy to install and use (you don't need to report for installation or apply for a registration certificate).
