Chemical storage tank is a kind of equipment for storing chemicals, and the selection of its materials is very important for the performance and safety of the tank. When selecting storage tank materials, common choices are cold-rolled plate and hot-rolled plate. So, is it better to use cold-rolled plate or hot-rolled plate for chemical storage tanks?

First of all, we need to know the difference between cold-rolled plate and hot-rolled plate. Cold-rolled plate is processed by cold rolling mill at room temperature. Its surface is smooth and its dimensional accuracy is high, but its strength and toughness are relatively low. Hot rolled plate is processed by hot rolling mill at high temperature, with rough surface, but relatively high strength and toughness.

For chemical storage tanks, the main considerations are the corrosion resistance and pressure resistance of materials. In these two aspects, hot-rolled sheet has more advantages than cold-rolled sheet. Hot rolled sheet has higher strength and toughness, can bear greater pressure and weight, and is more corrosion resistant. However, the strength and toughness of cold-rolled plates are relatively low, which is easy to be corroded by chemicals, thus affecting the service life and safety of storage tanks.

In addition, the price of hot rolled plate is relatively high, but its performance is more stable and reliable, which can ensure the safety and stability of storage tank. Therefore, for chemical storage tanks, it is more appropriate to choose hot rolled plate as material.

To sum up, hot rolled plate is more suitable for chemical storage tanks. Hot-rolled plate has higher strength and toughness, can bear greater pressure and weight, and is more corrosion-resistant, which can ensure the safety and stability of storage tanks.
