Heating pipes, metal pipes made by foreign visitors into the high electric resistance alloy wire for heating materials, electric wire around the filling and compaction, with good insulation properties, high thermal conductivity with high purity magnesium oxide as a filler, The product is the inherent power, high thermal efficiency, heat dissipation, and long service life. Application: mainly used for heating air duct central air conditioning units, ceiling air conditioners and household air conditioners, as well as dryers, heaters and other heating products. Commonly used in plastic packaging, small mold heating, analytical instruments, cigarette industry, the footwear industry, semiconductor eutectic welding, casting and heat input channel no water injection, cooling effect of the expansion of gases such as when heated. Structure: resistance wire installed in the ceramic tube, filling magnesium oxide powder, ceramic tube around the strip steel exterior kit tube, external galvanized layer, can rust. Heating pipe with both ends of the connection nut, pad, connect the power cord for use. According to user requirements size and power requirements of design.
