The skin effect current heating method (abbreviated as SECT method) is a new type of pipeline heating system that emerged in the mid-1960s. "SECT" is likely an abbreviation for "SKIN ELECTRIC CURRENT TRACING," translating to "skin effect heating." Due to its simple structure, safety, reliability, long lifespan, ease of automation, and high energy utilization, it has quickly gained attention and research both domestically and internationally.
SECT skin effect heating cables (skin effect current heating) systems were early applied in Japan and later extended to countries like the United States and Canada, gaining more and more applications. The SECT skin effect heating technology was first used in our country in the 1980s, with WanLian Group relying on its long-termElectric Trace HeatingTechnical reserves and experience allow us to provide mature product design, comprehensive system installation, and reliable heating devices to our customers.
