Heating pipe parameters: 
 The tubular heating element is a metal tube housing (iron, stainless steel, copper, etc.), along the tube center AXIAL spiral heating alloy wire (nickel-chromium, iron, chromium alloy) gap fill compaction has good thermal insulation properties of crystalline oxide magnesia, both ends of the nozzle with a silicone seal the deal with heating elements made by other processes. This metal sheathed heating elements can heat the air, the metal mold and a variety of liquids. It has a simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long service life. Applicable to a variety of saltpeter tank, sink, tank, acid-base slot heat fusible metal melting furnace, air furnace, oven, hot stamper and other devices. Widely used in aviation, shipbuilding, petroleum, chemical industry, washing, chemical fiber, machinery manufacturing, automotive, electrical, radio, instrument, plastic, textile, food, printing and packaging, rubber, medical and health, household appliances and other industrial sectors. 
 Boiler electric heating elements can be divided into single-ended, double-ended flange bundle of three heating pipes 
 (A) single-ended boilers of electric heating elements: a unique production process, small size, high power density, reasonable structure, long life, easy installation and maintenance features, provide the overall technical level of the electric boiler, safety and reliability is currently the first choice for domestic electric boiler electric heating elements.
