-------Structure
Tube heater elements are made of metallic tube, heating alloy wire and mgo. The material of metallic tube is Stainless Steel, iron, copper and so on. In the middle of the tube, there are spiral alloy wire (nickel-chrome, ferrochrome)and be filled with the mgo . as the insulation thermal conductivity. The two ends of the tube is sealed with silicone.
-------Advantage
It could heat air, metal mold and kinds of liquid. It has a simple structure, high mechanical strength, high thermal efficiency, safety and reliability, ease of installation, long service life and so on.
It can be used for all kinds of saltpeter, water tank, oil tank, acid tank fusible metal heating and melting furnaces, air heater, oven, hot die and other devices.
------Usage
Widely used in aviation, shipbuilding, petroleum, chemicals, washing, chemical fiber, machinery, automobile, motor, radio, instrument, plastic, textile, food, printing and packaging, rubber, pharmaceuticals, household appliances and other industrial sectors.
