1. Background.
Storage tank is a widely used storage equipment in petroleum, chemical, food, pharmaceutical and other industries, due to the particularity of its environment, the storage tank is prone to corrosion and damage, which seriously affects the safety production and economic benefits of the enterprise. Therefore, how to effectively carry out the anti-corrosion construction of storage tanks has become the focus of enterprises. This article will introduce the steps, technical requirements and precautions of storage tank anti-corrosion construction in detail, and provide enterprises with a comprehensive guide to storage tank anti-corrosion construction.

Second, the construction steps.
1.Preparation for construction.
Before construction, the construction site needs to be cleaned and inspected to ensure that the construction site is safe and tidy. At the same time, it is necessary to prepare the personnel, materials and equipment required for construction.
2.Surface treatment.
Surface treatment is an important part of anti-corrosion construction, which needs to remove dirt, oil stains, rust and other impurities on the surface of the storage tank, and ensure that the surface is dry and smooth.
3.Painting application.
Coating construction is the core link of anti-corrosion construction, and it is necessary to select the appropriate anti-corrosion coating according to the use environment of the storage tank, corrosion characteristics and other factors, and paint according to the requirements.
4.Quality inspection.
After the coating construction is completed, the quality inspection of the anti-corrosion coating needs to be carried out to ensure that the coating quality is qualified.
5.Acceptance delivery.
After the completion of the quality inspection, the storage tank needs to be accepted and delivered to ensure that the storage tank meets the use requirements.
3. Technical requirements.
1.Paint selection.
It is necessary to choose the appropriate anti-corrosion coating according to the use environment of the storage tank, corrosion characteristics and other factors, such as epoxy resin coating, polyurethane coating, etc.
2.Painting process.
It is necessary to choose the appropriate coating process according to the shape, size and corrosion degree of the tank, such as brushing, spraying, scraping, etc.
3.Coating thickness.
It is necessary to determine the coating thickness according to the use requirements of the storage tank and the technical requirements of the anti-corrosion coating, and the coating thickness is generally required to be 05-1.0 mm.
4.Surface treatment requirements.
The surface of the tank needs to be thoroughly cleaned, including oil stains, rust, impurities, etc., and the surface needs to be dry and smooth.
5.Safe operating requirements.
During the construction process, it is necessary to comply with the relevant safety operation procedures to ensure construction safety.
4. Precautions.
1.Adequate safety risk assessment needs to be carried out before construction to ensure the safety of the construction site.
2.During the construction process, it is necessary to ensure that the storage and use of the paint comply with the relevant regulations.
