Corrosion protection of tanks is one of the key tasks in the field of metal structures operation, especially those exposed to aggressive environments. The choice of a suitable anticorrosion coating can significantly affect the service life of the equipment and operational safety.Main methods of anticorrosion treatment
Gas-thermal method
Gas-thermal treatment is one of the most effective methods of corrosion protection. This method consists of using a flame to sinter special anticorrosion compositions.
Pros of the gas-thermal method:
- High durability of the coating. Gas-thermal application creates a durable and resistant to mechanical damage layer.
- Speed of application. The coating process takes less time compared to other methods.
- No solvents. The risk of negative impact on the environment is reduced.
Minuses of the gas-thermal method:
- Special equipment requirements. Specialized equipment must be used, which can increase initial costs.
- Need for qualified personnel. Experienced personnel are required to perform the work.
ANTICOR equipment for gas-thermal spraying of anticorrosion coatings combines all the advantages of the gas-thermal method, while not requiring highly qualified personnel and has a low cost. Thus, ANTICOR equipment opens new horizons, combining speed, economy and high quality of anticorrosion coatings, which is especially important in modern conditions.
Gas flame method
The use of mobile equipment for the gas flame application of high molecular weight polyethylene and thermoplastic paints is becoming increasingly popular. This method takes into account all the latest advances in corrosion protection.
Pros of the gas-flame method:
- Flexibility in operation. The mobility of the equipment allows it to be used directly at the site of the tanks, which significantly reduces the time for transportation.
- Resistance to chemicals. High molecular weight polyethylene coatings protect well against various aggressive media.
- Resource saving. The need for additional transportation and related costs is reduced.
Minuses of the gas-flame method:
- Need for preparation of the working surface. It is important to thoroughly prepare the surface of the tank before application.
The portable
ANTICOR POLY unit for gas-flame spraying of thermoplastic protective coatings, designed for efficient operation in a variety of operating conditions, combines all the advantages of the gas-flame method, while not requiring highly qualified personnel and has a low cost. ANTICOR POLY is highly mobile, which allows to fulfill large orders in a short time and adapt to individual customer requirements.
Paint coatings
Paint coatings remain one of the most common methods of corrosion protection. These coatings can be based on alkyd, epoxy, polyurethane and other resins, each with its own anti-corrosion properties.
Pros of paint coatings:
- Wide selection. There are many formulas and colors on the market to suit different conditions.
- Relative ease of application. Applied using traditional methods: brush, roller or spray.
Minuses of paint coatings:
- Requires surface preparation. Careful preparation is required to achieve good adhesion;
- Limited service life. Some coatings may require periodic restoration;
- Special expensive coatings are required for corrosive environments.
Waterproofing Coatings
Waterproofing sprays and materials are applied to the surface of the tank to protect it from moisture and corrosive agents. They can be either liquid or in the form of films.
Pros of waterproofing coatings:
- Waterproofing. Effectively protects against moisture, which is especially important for tanks.
- Flexibility. Various forms are available, from liquid to polychlorovinyl films.
Minuses of waterproofing coatings:
- Temperature sensitivity. Require certain temperature conditions during application.
- Difficulty in repair. Damage requires reapplication of the entire layer.
- Special expensive coatings are required for aggressive environments.
Zinc coating
Zinc protection is accomplished by hot-dip galvanizing or cold zinc spray application. The zinc serves as a “victim”, protecting the base metal from corrosion.
Pros of zinc coating:
- Durability. Zinc coating can last for decades if applied properly.
- The process can be done on site. The structures being treated do not have to be dismantled.
Minuses of zinc coating:
- Environmental influences. Zinc can react with other metals in the presence of moisture.
- Requires specialized equipment. Hot-dip galvanizing requires industrial installations.
Conclusion
The choice of corrosion protection coating method depends on specific operating conditions and budget. Among modern technologies, gas-thermal and gas-flame methods are the most effective and reliable methods of protection that ensure long-term operation of tanks.
The right choice of equipment and a competent approach to the application process will significantly increase the service life of metal structures and minimize repair and maintenance costs.
