Pipe skin effect electric tracing (skin electric heating) technology is a new metal pipeline heating method that has emerged in recent years. It represents a new technique and process for heating and insulation of thermal transmission pipelines in large-scale petrochemical and other enterprises, and is abbreviated as "SECT method" internationally. This heating technology is characterized by high efficiency, adaptability to tracing and heating of all long, medium, and short-distance metal fluid pipelines, and boasts advantages such as safety, reliability, and ease of installation and maintenance. Therefore, it is widely used in the transportation of various types of liquid substances through pipelines.
