A:The choice of steam generator pressure vessel, air storage tank is a common industrial equipment for purifying compressed air. It is also one of the special safety equipment strictly regulated by the state. In order to ensure safe use, how will we choose a safe gas storage tank? The summary is divided into five steps.
The appearance of the product reflects the grade and value of the product. Only regular, powerful manufacturers with advanced equipment and a good quality assurance system can guarantee the quality of product appearance.
The trademark of a good-quality gas tank is obvious, and the brand of the gas tank can be clearly known at a distance of 50 meters from the gas tank.
The nameplate of the product should indicate the name and production date of the manufacturer and inspection unit. Whether there is a seal of the test unit in the upper right corner of the nameplate, the product number, weight, volume size, hydraulic test pressure and medium must be indicated on the nameplate.
Look at the quality assurance certificate According to the relevant national regulations, each gas storage tank must have a quality assurance certificate before leaving the factory. The quality assurance certificate is the main certificate to prove the qualification of the gas storage tank. But to ensure safe use, please do not buy.
How to choose a pressure vessel for a gas steam generator depends on the qualification of the manufacturing company. The qualifications and reputation of a powerful brand-name enterprise are unmatched by ordinary enterprises.
Although some small enterprises have a pressure vessel manufacturing license, the overall equipment is outdated and the management is not standardized. The produced gas storage tanks are likely to have potential safety hazards. unnecessary trouble.
Then require the manufacturer to issue the inspection certificate of the local special equipment supervision institute, and then ask the special equipment supervision institute where the company is located to conduct another inspection before leaving the factory. Generally, the exhaust pressure of the air compressor is 7, 8, 10, 13 kg, of which 7, 8 kg is the most common. Therefore, generally 1/7 of the air volume of the compressor is used as the selection criterion for the capacity of the oil tank.
