Cisterns for the chemical industry and your safety
In the chemical industry, tanks are used to store and transport chemicals and flammable liquids. Tanks containing corrosive substances can weaken over time and start leaking. Damaged tanks can cause production to stop. That's bad enough, but maybe not the worst. Hazardous substances can leak out and harm the environment or people. That's why it's important to regularly inspect and maintain tanks containing chemicals. If the inspection shows that the tank needs renovation, we have a solution. Cistern Solutions has developed a method for repairing damaged tanks - a method that stands up to the tough demands of the chemical industry.

Materials in tanks for the chemical industry
The most common material for tanks in the chemical industry is stainless steel. Chemical products put a lot of stress on the tank and stainless steel is tough. There are several types of stainless steel, including acid-resistant steel. It is important to choose the alloy that has good corrosion resistance for the medium in the tank. Sometimes the right alloy is too expensive. In that case, polyethylene or fiberglass tanks are also durable alternatives. A third option is double-jacketed tanks with an inner jacket in stainless steel with an outer one in plain. All types of tanks can have a protective coating inside, such as epoxy, as extra protection
Causes of damage to tanks in the chemical industry
Corrosion: Chemicals can be highly corrosive and over time can cause damage to the tank. Acids, bases and other industrial substances increase the risk of corrosion, especially at high temperature and humidity. Corrosion breaks down tank material at the molecular level. In the worst case, cracks and holes form where harmful contents can leak out and become dangerous for both workers and the environment. External factors such as shocks, vibrations and extreme temperatures can also damage tanks. Ageing and wear and tear. Chemical reactions: Some chemicals react violently when mixed. This can happen if one chemical is left in the tank and another is added. The reaction can create more heat or pressure than the tank can handle, resulting in damage or, in some cases, an explosion.
Repair of tanks for the chemical industry
Despite regular maintenance, a cistern can get damaged. If the damage is not too severe, it is possible to repair cracks, holes and strengthen the strength of the tank. Cistern Solutions has developed a method that both repairs and protects tanks against corrosive substances. We coat the inside of the tank with an epoxy coating, which acts as a barrier against chemicals. At the same time, the coating reinforces the structure of the tank. You basically get a new high-strength tank inside the old one. The method is the same for all types of tanks, but the coating is adapted to the damage and the chemicals the tank handles. Instead of replacing the tank, we give it many more years, with the same safety and functionality. This is both good for the economy and gives you a sustainable production.
Among other things, the Civil Contingencies Agency has regulations for handling flammable liquids.
