Electric heater tube U type

stainless steel electric heater tubeuse the metal tube for the shell (iron, stainless steel, copper, etc.), along the axial center,evenly use the spiral electric wire alloy (nickel chromium, chromium iron alloy) to fill the gap with magnesium oxide crystal sand with the characteristics of good compaction thermal insulation properties. sealed both ends with silicone, then in the process of the other electric components. This sheathed electric metal heating elements can beused to heat air, liquid and all kinds of metal mold.

----simple structure, high mechanical strength, high thermal efficiency, reliability, ease to installation, long service life and so on. Applicable to heat saltpeter slot, water slot, oil slot, and acid-base slotand other fusible metal melting furnace, air heating furnace, oven,and other devices. Widely used in aviation, shipbuilding, petroleum, chemicals, washing, chemical fiber, machinery manufacturing, automotive, instrumentation, plastics,textiles, food, printing and packaging, rubber, medical and health, household appliances fields
