Methods and equipment for air tightness testing of pressure vessels

gasTightness test设备The application of pressure vessel is more and more widely, especially in pressure vessel

密性检测How to do itWhat are they? What should we pay attention to? What kind of equipment is good? Here's how to share one by one

Here you are.


The pressure vessel shall be tested for air tightness according to the following requirements:
(1)Air tightness检测The test shall be conducted after the hydraulic test is qualified. Air pressure test for design requirements

Pressure vessel, air tightness testIt can be carried out at the same time with the air pressure test, and the test pressure shall be the pressure of the air pressure test.

(2) For pressure vessels made of carbon steel and low alloy steel, the temperature of test gas shall not be lower than 5 ℃,

Pressure vessels made of other materialsThe force container shall be in accordance with the design drawing.

(3)气密性检测The gas used in the test shall be dry and clean air, nitrogen or other inert gas

Body.
(4) Go ahead气密性检测During the test, the safety accessories shall be installed completely.
(5) During the test, the pressure shall rise slowly, keep the pressure for not less than 30 minutes after reaching the specified test pressure, and then

Reduced to design pressure, rightAll welds and connecting parts shall be inspected with soapy water, and no leakage shall be considered as qualified. if there be

Leakage, repair after the hydraulic test and repair气密性Test.


The optimal design of pressure vesselAir tightness testing equipment

Harris high precision气密性检测仪-From 2008 to 2016, the company has experienced nine years, and has integrated into a wealth of air tightness inspection

Test experience and new research and developmentTechnology. Nowadays, the new high-end intelligent automation technology is becoming more and more popular气密性检测设备It's already out there. sea

Reese气密性检测System, according to differentThe purpose of use, such as waterproof test, sealing test, leakage test,

IP level detection, detect the corresponding effect, intuitive and easy to operateGas detection system operation interface, practical

More flexible.
