Which of the following materials is recommended for construction of heating oil tanks?

The recommended material for the construction of heating oil tanks is corrosion-resistant steel. This material is especially suited for heating oil tanks because of its ability to withstand the corrosive effects of oil and environmental factors. Corrosion-resistant steel is specifically designed to prevent rust and deterioration, which can compromise the integrity of the tank and lead to leaks.

Using a durable and reliable material like this ensures the tank can handle the pressures of the heating oil it contains and the conditions it will be exposed to over time. This helps in maintaining safety and environmental compliance, minimizing risks of spills or contamination. Other materials may not provide the same level of durability and long-term reliability, making corrosion-resistant steel the best choice for this application.
