STAINLESS STEEL TUBE
The stainless steel electric heating tube is made of stainless steel as the sheath, magnesium oxide powder as filler, heating wire and sealing material. In the process of manufacturing stainless steel heating tubes, stainless steel 304 is used the most. It is widely used in heating liquids (without strong acid and alkali) and air heating. It has good comprehensive performance, easy to shape and moderate price. Most used in heating tube manufacturing. Other stainless steel , such as 304L, 321, 316,302 etc. also often be applied for heating tube. Stainless steel electric heating tubes can only be made of different stainless steel materials according to different working environments.
The copper electric heating tube is a copper tube as the shell, and the spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is uniformly distributed along the central axis of the tube. The gap is filled and compacted with magnesium oxide powder with good insulation and thermal conductivity. And ceramic seal, this metal armored electric heating element can heat air, metal molds and various liquids.
The general heating tube material is composed of aluminum tube, heating wire, magnesium oxide powder, ceramic particles, lead rod and other main materials. Only these materials can make a perfect aluminum heating tube. The aluminum heating tube can be worked upon air or water. Aluminum tube performance: corrosion resistance, light weight.
QUARTZ TUBE DIE
Also known as halogen heating tube: a tungsten filament is placed in a quartz shell, working temperature is high and the selection range is wide. Among them, the ceramic cap package type has a maximum temperature resistance of 800°C. Fast heating, low thermal inertia, high temperature resistance, corrosion resistance, good thermo chemical stability, long service life and high insulation strength. Compared with ordinary infrared heating, heating equipment such as heaters and oven drying tunnels that use this tube as a heating element can greatly improve work efficiency, shorten the heating cycle, save equipment space, save energy, and reduce production costs.
The Iron heating elements is a metal tubular electric heating element with an iron tube shell. This structure is not only advanced, high thermal efficiency, but also generates uniform heat. When there is current through the high temperature resistance wire, the heat generated is beautifully oxidized by high temperature. The powder diffuses to the surface of the metal pipe, and then is transferred to the heated part or the space environment to indirectly heat the object, achieving the purpose of electric heating. The product has the advantages of simple structure, long life, high thermal efficiency, good mechanical strength, can be bent into various shapes and safe to use.
