First, let's take a look at the introduction of the product
U / W type electric heating tube with metal tube as the shell, along the direction of the central axis of the tube evenly configured spiral electric heating alloy wire (nickel-chromium alloy, iron-chromium alloy), fill the gap, fill the magnesia with good insulation and thermal conductivity, seal the two ends of the nozzle with silicon or ceramic, the metal sheathed electric heating element is made of air, mold and each
Second, the characteristics of U/W type electric heating tube:
U/W type electric heating tube has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long life.
Third, the product use of U/W type electric heating tube
U/W type electric heating tube is widely used in various saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot pressing molds and other devices.
The above is the knowledge introduction of U/W type electric heating tubes introduced to you today, and other electric heating tubes will be introduced tomorrow.
(1) Characteristics of electric heating tube 1: long life
The spiral electric hot wire is surrounded by dense insulation thermal conductive filler, isolated from the outside, the end of the electric heating pipe has sealing material, the spiral electric hot wire is not easy to oxidize, the life is very long, normal and reasonable design, manufacture and use, its life can reach more than 10 years
(2) Characteristics of electric heating tube 2: high mechanical strength
The shell sleeve of the electric heating tube is made of seamless metal pipe, so it has sufficient mechanical strength, while the spiral electric hot wire and insulating filling material are tightly compressed into the metal tube, the density is above 33g/cm3, there is no relative displacement, it can withstand shock and vibration, and it can maintain performance under vibration conditions. Strong resistance to the destruction of foreign machines.
(3) Characteristics of electric heating tube 3: high efficiency
The electric heating tube is not charged on the surface due to the heating of electricity, so when heating the liquid, the tubular electric heating element is directly placed in the liquid, and its heat is absorbed by the liquid. The thermal efficiency can exceed 90%.
(4) Characteristics of electric heating pipe 4: power saving
The electric heating tube almost all directly heats the heated object, which is very efficient and can save the relative power consumption. The electricity required to heat the saltpeter tank using an electric heating tube can be reduced by 40%.
(5) Features of electric heating tube 5: simple structure, material saving, low cost
The structure of the electric heating pipe is simple, the alloy electric hot wire used is not easy to oxidize, the surface load of the electric hot wire is large, and the small section electric hot wire can be used, which can greatly reduce the material of the electric hot wire.
On the other hand, since there is a metal sheath on the outside of the electric hot wire, there is no relative displacement in the filling material, so the brittle iron-based alloy wire can be used instead of the nickel-based alloy wire, which greatly saves rare metals. Reduced product costs and investment expenses.
(6) Characteristics of electric heating pipe 6: safe use of filling material using good insulation heat conduction material, in the high temperature working state also has good electrical properties, high safety.
(7) Electric heating tube feature 7: can be bent into various shapes
Electric heating tubes are manufactured from straight pipes and can be bent into various necessary shapes after manufacturing.
(8) Characteristics of electric heating tube 8: easy to load and unload
Since the electric heating tube is a separate part, it is easy to replace in case of damage during use.
