The correct method of SF double-layer tank pressure test

The use of SF double-layer oil tanks has always been a problem that everyone is more concerned about, and pressure testing is also an indispensable link. It is very particular. So what are the correct methods for SF double-layer oil tank pressure testing? The following pressure vessel manufacturers give you a detailed introduction.
 
First of all, it is possible to perform a full water test on the open tank and tank installation of the SF double-layer oil tank, and to perform a hydraulic test on the closed tank and oil tank at 1.5 times the working pressure, but not less than 0.4mpa. Secondly, some construction units do not conduct a full water test on the open tank and the oil tank before installation, and check the leakage of the pressure vessel after use. According to the regulations, the experiment of filling the tank with water must wait for 24 hours to ensure the reliability of the experiment with full water. Finally, after the installation process of connecting the boiler and other equipment is completed, the hydraulic pressure test of the SF double-layer oil tank is performed, and the experimental pressure is greater than 1.5 times the working pressure.
 
The above is the correct method for the pressure test of the SF double-layer oil tank introduced by the pressure vessel manufacturer. I believe you have a new understanding. You can choose the appropriate pressure method according to the requirements of the oil tank and prepare for the pressure test.
