Explosion-proof electric heat tracing is different from flame retardant electric heat tracing, it is a special electric heat tracing, which is mainly used in explosion-proof occasions in industrial production. Its core function is to use electric heat tracing technology to prevent pipelines, tanks, pumps and valves and other equipment from freezing, solidifying and clogging in low temperature environments, so as to ensure the smooth progress of production.
When choosing electric heat tracing, the general model is marked with PF to indicate that the electric heat trace has explosion-proof function, but many people have found that some electric heat tracing PF logo has 2 or 46 words after the logo. Originally, there are different types of explosion-proof electric heat tracing, namely explosion-proof protection type (PF) and explosion-proof and anti-corrosion type (PF2, PF46).
What is the difference between explosion-proof protective type (PF) and explosion-proof and anti-corrosion type (PF2, PF46) electric heat tracing?
First of all, the easiest thing to distinguish is that the two products are used in different environments. Although they are all used in explosion-proof areas, if the medium in the pipes and tanks in the explosion-proof area is corrosive, then it is necessary to use explosion-proof and anti-corrosion electric heat tracing.
Secondly, the outer sheath of the explosion-proof electric heat trace is made of two materials, one is polyolefin and the other is fluorine. Explosion-proof protective electric heat tracing can be used with an outer sheath of polyolefin or fluoropolyolefin; However, the outer sheath of the explosion-proof electric heat trace must be made of perfluorinated material.
Finally, the two products are different, in general, the explosion-proof and anti-corrosion electric heat trace is higher than the explosion-proof protection electric heat tracing. This difference is mainly due to the difference in raw materials, the ** of fluorine materials is several times higher than that of polyolefins, which is naturally reflected in the electric heat tracing, and the electric heat tracing of fluorine materials ** is naturally higher than the electric heat tracing of polyolefins.
