Whether air storage tank and compressed air pipeline belong to special equipment

Gas tank and pressure pipe are short for two kinds of equipment. If you buy back a simple pressure vessel, you do not need special equipment installation qualification, free of record. However, the accessory box (pressure gauge and safety valve) of the gas tank is of strong inspection type. The general pressure gauge is tested once every six months, and the safety valve is tested once a year.

If you are engaged in the pressure pipeline industry, you must have special equipment installation qualification. Nominally, it can be said that it is a pipeline that receives internal pressure or external pressure of the storage tank. Whether it is storing air, nitrogen, steam, oxygen, etc., the pressure pipeline is a part of the pipeline. Pressure piping consists of pipe flanges, bolted connections, gaskets, valves, other components or assemblies of pressure parts and supports. This pipe cannot be ignored as long as it plays a role in use.

Many users do not understand that the gas tank is installed and used by themselves after buying it back. In fact, the installation is very simple. As long as the company has technicians, the operation can be basically completed by looking at the photos after installation. The difficulty lies in the lack of installation qualification, installation qualification must be approved by the relevant units, in line with the requirements to issue a certificate.

Because the pipeline installation is still more dangerous, especially the high-pressure pipeline, can not be operated casually. I hope you must confirm clearly when purchasing and installing gas storage tanks, and cannot blindly install and purchase.
