Must read! Key points of electric heating cables for oil storage tanks

Oil tanks are key facilities for storing oil products. The stability of their temperature is related to oil product quality and safe production. Under complex working conditions, electric heating cables become a powerful assistant to ensure the normal operation of oil tanks. The following is a summary of the key points of electric heating cables for oil tanks.

Safety

When using electric heating cables for oil storage tanks, safety is the primary consideration. Oil storage tanks store flammable and explosive oil products, and electric heating cables must have explosion-proof properties. Electric heating cable products that meet relevant explosion-proof standards should be selected, such as products that have passed the ExdⅡBT4 and other explosion-proof grade certifications. The installation of its electrical circuits must strictly follow safety regulations to prevent electric sparks. At the same time, the outer insulation material of the electric heating cable must have good oil and corrosion resistance to avoid damage to the electric heating cable due to oil leakage, which may cause safety accidents.

Heating efficiency

Heating efficiency is directly related to the temperature maintenance of the oil in the oil tank. High-quality electric heating cables can effectively convert electrical energy into thermal energy. According to Joule's law Q = I²Rt (where Q is heat, I is current, R is resistance, and t is time), its resistance value is reasonably designed and can generate sufficient heat at a lower current. In practical applications, it is necessary to select electric heating cables with appropriate power according to factors such as the size and shape of the oil tank and local climatic conditions to ensure that the oil tank can be heated evenly and efficiently to prevent the oil from solidifying or increasing in viscosity due to low temperature, which affects the normal use of the oil.

Installation Specifications

Correct installation is the key to the effectiveness of electric heating cables. When installing electric heating cables on oil tanks, first ensure that the tank surface is clean and dry. The electric heating cables should be evenly and tightly wound around the oil tank to avoid local overheating or uneven heating. During installation, pay attention to the bending radius of the electric heating cables, which should not be too small to avoid damaging the internal heating core wire. At the same time, the electric heating cables should be fixed well, and special fixing fixtures should be used to prevent the electric heating cables from shifting during use. In addition, the joints of the electric heating cables should be properly handled to ensure that the connection is firm and well sealed to avoid water ingress and moisture.

Maintenance and testing

Oil storage tank electric heating cables need to be maintained and tested regularly. During daily maintenance, check whether the appearance of the electric heating cables is damaged or aged. If any problems are found, replace them in time. Measure the insulation resistance of the electric heating cables regularly to ensure that their insulation performance is good. At the same time, check whether the temperature control device of the electric heating cables is working properly to ensure that the heating temperature is within the set range. In terms of testing, professional electrical testing equipment, such as megohmmeters, can be used to test the electrical performance of the electric heating cables. Only by doing a good job of maintenance and testing can we ensure that the electric heating cables can provide long-term and stable heating services for oil storage tanks.

Understanding the above four points is of great significance for effectively ensuring the stable and normal operation of oil storage tanks, maintaining the quality of oil products and ensuring production safety.
