When the flow of liquid in and liquid out is large in the use of anti-corrosion storage tank, vent holes with corresponding flow shall be installed. When changing the contents of liquid, it is necessary to know whether the anti-corrosion tank is allowed to contain liquid. If necessary, you can consult the company's website or contact the company's technical department. If there is a joint or flange connection at the lower part of the anti-corrosion storage tank, the pipe shall be perpendicular to the tank wall. It is better to use soft connection, so as to avoid the joint connection damage and leakage caused by uneven expansion of the upper and lower parts of the tank wall after the tank is filled with liquid. In serious cases, the joint and the tank body are damaged. When the liquid inlet is higher than the bottom of the tank, the liquid inlet shall bend to the wall of the anti-corrosion tank to let the liquid drop down along the wall of the tank, so as to reduce the impact on the bottom. The storage pressure of anticorrosive storage tank is large, so it should be strengthened when connecting with other flanges. The general flange and anticorrosive tank are generally tightened when leaving the factory, which may cause looseness during transportation, loading and unloading. The user shall check the sealing performance of the rolling plastic tank before use, and can add liquid to observe whether there is leakage. It is better to use water to test the leakage of the rolling plastic tank containing chemical liquid to prevent loss.
