1. Generally, PPH storage tank The anti-corrosion means include cathodic protection and layered protection. Coating protection can be divided into two ways, including anti-corrosion treatment inside the tank and anti-corrosion treatment outside the tank:
1. For oil storage or oil tank, the performance of anti-corrosion coating requires that it is conductive electrostatic in the tank, so conductive electrostatic coating is used for anti-corrosion treatment of the tank.
2. The treatment of anti-corrosion coating outside the tank is to comprehensively consider the anti-corrosion performance, weather resistance and aesthetic performance of the tank.
PPH tank
Secondly, PPH storage tank must consider the temperature resistance characteristics of each anti-corrosion coating when designing the anti-corrosion coating, and at the same time, it must be compatible. If alkyd anti-corrosion coating is used, it needs to avoid direct matching use, which is due to the chemical reaction with zinc powder.
3. The cathodic corrosion protection of water tank is divided into cathodic protection of impressed current on the outside of water tank bottom plate and protection treatment of water layer anode in water tank
Precautions to prevent cracks in PPH large oil storage tank:
(1) Correct selection of raw materials and control of quality level.
(2) Reasonably design and manufacture pipes with reasonable structure.
(3) Heat treatment shall be carried out in strict accordance with the requirements.
(4) Minimize the number of joints.
(5) Ensure uniform pipe wall thickness.
(6) Increase the wall thickness appropriately.
(7) Multilayer staggering is adopted.
(8) Remove the root cause of stress concentration. PPH mixing tank
