PPH storage tank It has been used in the above industrial production and has a longer service life under natural conditions, because under the same application conditions, PPH tanks are superior to tanks made of other materials in many aspects. There are many advantages, so carefully check the PPH tank before use to ensure that it is suitable for you. PPH mixing tank

First, the appearance of PPH storage tank should be checked before use, and the surface should be free of cracks, shrinkage cavities, slag inclusion, folding, double skin and other defects. The corrosion depth and mechanical damage depth of the depression shall not exceed the negative wall thickness deviation allowed by the corresponding product standard.

Secondly, the shell test pressure of PPH tank valve should be less than about 1.5 times of the nominal pressure, and the test time should be less than about 5 minutes. The casing packing is qualified if there is no leakage, and the sealing test is conducted under the nominal pressure, and the valve sealing surface is qualified if there is no leakage.

After that, please observe the external steel wire surface of the pph tank, and then add the precision and surface roughness, which should conform to the design concept or specification, and should have the ability to identify goods.

Although PPH storage tank has the advantages of corrosion resistance, wear resistance, no leakage, no separation, and long service life. Yes, it is an ideal container for storing and transporting corrosive liquids, and also has the defect of solder skips.

For oil storage tank or oil products, the required performance of anti-corrosion coating inside the tank is electrostatic conductivity. Therefore, in the process of anti-corrosion treatment of storage tanks, electrostatic conductive coatings are used for anti-corrosion treatment of storage tanks. The treatment of anti-corrosion coating outside the tank is combined with the anti-corrosion performance, weather resistance and aesthetic performance of the tank.

When designing the anti-corrosion coating of PPH storage tank, the temperature resistance characteristics of various anti-corrosion coatings should be considered, which are interchangeable. Direct combination shall be avoided in aldehyde anti-corrosion coating. This is due to chemical reaction with zinc powder. The cathodic corrosion protection of storage tank can be divided into the compressed current cathodic protection on the tank bottom plate and the cathodic protection treatment of the tank water layer anode.
