1. Electrical heating characteristics:
In addition to the performance of ordinary heat tracing, low-temperature self-limiting electric heat trace also has explosion-proof and anti-corrosion properties.
"Explosion-proof" refers to the place where a layer of wire braid is added to form a shielding layer outside the basic self-limiting temperature trace, which has the effect of grounding and enhanced protection, and is suitable for explosion-proof needs.
"Anti-corrosion" adds a layer of fluoroplastic outer sheath to the shielding layer to meet the needs of corrosion resistance. It is suitable for chemical, power plant and other places that require anti-corrosion performance.
Self-limiting temperature electric heat trace
Second, the application area of electric heat tracing:
Self-limiting temperature electric heat trace is also known as "self-limiting heat trace, self-controlled temperature electric heat trace". Self-limiting temperature electric heat tracing is heated by electric energy and plays a role in heat preservation. Self-limiting temperature electric heat tracing is suitable for heat tracing, anticoagulation and antifreeze of pipelines and storage tanks in pipelines and storage tanks in ordinary areas, danger areas and corrosion areas, petroleum, solar energy, fire protection, chemical industry, metallurgy, light industry, food, electric power, refrigeration, construction, natural gas, agricultural and sideline products production, processing and other departments.
