Heating cable selection in different long-distance pipelines

Heating cables are an effective method of pipe insulation and are widely used in petroleum, chemical, construction, electric power and other industries. For heat tracing in long-distance pipelines, the selection of heating cables is very important. Compared with traditional water heating, heating cables have the characteristics of higher thermal efficiency, lower energy consumption and simpler installation and maintenance.

The following are the heating cable strap models and specifications we have selected for different situations.

1、For pipes whose temperature needs to be heated is not high, generally less than 60℃, use ordinary heating cables. This heating cable is suitable for most liquid and gas pipelines, such as water, steam, petroleum and chemicals. Ordinary heating cables can provide stable heating power to ensure that the medium temperature inside the pipeline is maintained within the required range.

2、For pipes that need to be heated at a higher temperature, above 60°C, use high-temperature heating cables. High-temperature heating cables are designed with high-temperature materials and special insulation layers, which can withstand higher temperatures and pressures. They are suitable for high-temperature and high-pressure pipes, such as hot water, steam and certain chemicals.

3、 For long-distance pipes that need to be heated, the diameter and material of the pipe need to be considered. For smaller diameter pipes, you can choose a thinner heating cable, while for larger diameter pipes, you need to choose a thicker heating cable. At the same time, if the pipeline is made of stainless steel or explosion-proof materials, special heating cables need to be selected to avoid damage to the pipeline.

4、In addition to the above factors, the location and environment where the pipeline is located also need to be considered. For example, outdoors or in environments with corrosive gases, you need to choose heating cables that are more corrosion-resistant and explosion-proof. In flammable and explosive places, it is necessary to choose explosion-proof heating cables to ensure safety.

In short, for the selection of heating cables for different long-distance pipelines, it is necessary to comprehensively consider many factors such as the material, diameter, heating temperature, and environmental factors of the pipeline according to the actual situation to select the appropriate heating cable model and specification to ensure the safety of the pipeline heating system. , efficient and durable operation.
