The anti-corrosion layer of corrosion-resistant storage tanks, key points of storage tanks, and inspection items

Compared to ordinary chemical storage tanks, anti-corrosion storage tanks are bound to have outstanding anti-corrosion performance, because the internal coating of anti-corrosion storage tanks adopts solvent-free epoxy primer and epoxy glass flake coating for heavy anti-corrosion structure; The bottom surface of the floating ship's bottom plate adopts an epoxy anti-static double-layer structure for corrosion prevention.

The epoxy solvent-free non-toxic coating used for anti-corrosion storage tanks is a type of anti-corrosion coating with excellent corrosion resistance and resistance to mechanical damage. It has a series of outstanding properties, such as good mechanical properties, excellent corrosion resistance, and good construction operability.

For anti-corrosion storage tanks, even if they have anti-corrosion performance, they still need to pay more attention when storing liquids. Firstly, there should be good drainage ditches and dilution devices around the site where anti-corrosion storage tanks are placed. In cases where the tank level cannot be controlled, overflow ports should be installed on the tank to prevent liquid overflow and unnecessary injury.

If the inlet and outlet flow rates of the anti-corrosion storage tank are large, corresponding exhaust holes should be installed. When changing the contained liquid, it is necessary to understand whether the anti-corrosion storage tank allows the contained liquid. If there are joints or flange connections in the lower part of the anti-corrosion storage tank, the pipes should be perpendicular to the barrel wall and soft connections should be used to avoid uneven expansion of the barrel wall after being filled with liquid, which may damage the joint connection and cause leakage, and in severe cases, damage the joint and barrel body.

If the inlet of the anti-corrosion storage tank is higher than the bottom of the tank, the inlet should be bent towards the wall of the anti-corrosion storage tank to allow the incoming liquid to fall down along the wall and reduce the impact on the bottom. Due to the high storage pressure of the anti-corrosion storage tank, it should be strengthened when connected to other flanges. General flanges and anti-corrosion storage tanks are usually tightened when they leave the factory, which may cause looseness during transportation and loading and unloading. Users should check the sealing performance of the rotational plastic storage tank before use and add liquid to observe if there is any leakage.

Not only that, anti-corrosion storage tanks also need regular inspections, which include analysis of corrosion types, depth of corrosion, weld conditions, and analysis of corrosion products; Microscopic examination, flaw detection, degree of aging, cracking, detachment, wear and other damage of the anti-corrosion coating, etc. The state monitoring instruments to be gradually adopted are used to monitor the corrosion status of the anti-corrosion storage tanks in operation, laying the foundation for predicting maintenance.
