Vacuum tank and gas storage tank are both pressure vessels frequently used in industry. The appearance of the two pressure vessels is the same, but the actual structure, principle and use are different. The pressure inside the vacuum tank is negative pressure, that is to say, the pressure inside the tank is smaller than that outside and the pressure. Generally, the vacuum tank is connected behind the vacuum pump for use ; The pressure in the air tank is positive pressure, which can be distinguished by size. It is usually connected to the air compressor.

Gas storage tank is a kind of storage and transportation device, which is commonly used in petroleum, chemical and metallurgical industries and belongs to industrial equipment. According to the gas storage pressure, it can be divided into low pressure and high pressure, and then the low pressure gas storage tank can be divided into wet type and dry type according to the structure. If the vacuum tank is used as a vacuum tank, the pressure cannot reach positive pressure, and the pressure of the air tank used as a vacuum tank cannot become positive pressure. Therefore, the two are completely different pressure vessels, and mixing them will be more dangerous. At present, there are many brands of pressure vessels in the market, and many people are blind when choosing pressure vessels. They don't know which one is better. Customers can learn about the brand of goods and product quality.

Steam storage tank manufacturer The tank body is a vertical cylinder welded with steel plates, with a piston inside, and gas is stored below the piston. The piston rises and falls with the amount of gas stored. A sealing mechanism is installed around the piston to prevent the escape of stored gas. Place a weight on the top surface of the piston to obtain the required gas storage pressure. According to the sealing mode, it can be divided into oil sealing type, grease sealing type and flexible film sealing type.

The gas tank belongs to the canned equipment ( Generally refers to canned dangerous goods ), With air receiver , Natural gas storage tank , low pressure gasholder , Biogas storage tank, etc !

for example : What does the sign on the liquefied gas tank represent, TP3.2 WP2.1 GB5842 , 　

TP3.2 : Design pressure

3.2MPA WP2.1 : Service pressure

2.1MPA GB5842 : Manufacturing standard

When pouring backward, pay attention to the airtight connection of the pipeline, the change of filling pressure, and the formation of pressure difference , Steam storage tank manufacturer Remind to pay attention to fire prohibition and static electricity on site.
