Oil tanks play a very important role in the process of oil and gas storage and transportation. In oil and gas storage, oil tanks are mostly used for oil storage. When oil is needed, the oil is discharged from the tank. In the process of oil output, it is inevitable that such a problem arises. Because the temperature of the oil is low, the oil becomes viscous, so that the fluidity of the oil is lowered, and the oil cannot be smoothly outputted from the oil tank. The problem, how to solve it? Introduction, the new tank local rapid heating technology has solved this problem very well.
