Carbonic acid ester is a compound in which the hydrogen atoms of the two hydroxyl groups (-OH) in the carbonic acid molecule are partially or completely replaced by alkyl groups (R, R'). It is decomposed into carbon dioxide and alcohol in case of strong acid. The carbon dioxide produced during the decomposition of carbonate has brought certain pollution to the air and harmed the ecology, while the alcohol will condense due to the influence of temperature during transportation, leading to blockage of the pipeline. Therefore, it is necessary to use insulation products to maintain the pipeline in the normal operating temperature range.

     The use of electric heating products can not only easily solve the problem of pipeline freezing, but also effectively improve the flow of the pipeline and its production efficiency. According to the needs of different occasions, electric heating cables can be divided into multiple models, such as civil solar electric heating cables, industrial self-limiting temperature electric heating cables, constant power electric heating cables and MI armored heating cables.

     Electric tracing cable is a uniform heat release along the length of the pipeline or a large area of ​​the tank volume. It is different from a heat tracing product where the heat load is highly concentrated on a point or a small area. Electric heating system has small temperature gradient, long thermal stability time, high thermal efficiency, energy saving, simple design, convenient installation, pollution-free, and long service life. It has been widely used in various industries for antifreeze insulation and anticoagulation of pipelines and storage tanks. middle.
