Abstract: The article focuses on the experiment on storing lub oil in the heated lub oil tank made of bricks.Herein is briefed the structure of the tank and the way to prevent leaking, the calculation of the heat stress resulting from temperature rising, determination of the most unfavorable working state of the structure-section, and the temperature rising on the part of tank walls while oil product is heated, and its duration and economy as well.The author thinks it is feasible to store heated lubricant in brick tanks with a capacity of no more than 500 m³.Some problems worth attention are also listed.
