Product Description:

Four Holes Quartz Capillary Tube

High purity quartz ,SiO2> =99.99%

High temperature resistance

High orrosion resistance

We are specialized in manufacture four orifices quartz tube(Diameter2.8-4.4 ×520mm). The inner hole position is accurate and the aperture is well-proportioned. The four orifices quartz tube is mainly used in metrical instrument and thermometric element.

According to customer request we can make different size.

Q:What can be cut off by a quartz tube?
Resin diamond ultra thin cutting blade, cutting quartz glass tube, rod piece and so on. It has the characteristics of cutting, no collapsing, sharp and wearableAnother way is if the English word Lishi tube factory near to be sent to them all! Now this generation of cutting business is also very fire! Conventional quartz tube length is 1240MM!
Q:Halogen tube, quartz tube, carbon fiber, which is good?
Carbon fiber is good.The carbon fiber electric heater is a new type of electric heater designed and made of high and new material carbon fiber heating wire as heating element. With thermostat, remote control, new carbon fiber heater, new carbon fiber heater with heating and heating function, as well as radiation of far infrared, green, high efficiency, energy saving, safe and convenient.
Q:Quartz heating tube and carbon fiber, which saves electricity?
Energy consumption comparison: the quartz heating tube is heated by the resistance of the Ukrainian filament. The carbon fiber heater is pure black material in electric thermal conversion process, visible light is very small, the electrothermal conversion efficiency is more than 95%, than Cr, tungsten materials as the heater of the heating body, can save 30%.
Q:Which is more efficient, electromagnetic high frequency cooker and light wave oven?
The light wave furnace is more energy efficient than the electromagnetic high frequency cooker. The reason is that the heating method is more optimized.Ordinary microwave oven: the inner barbecue pipe is usually made of copper tube or quartz tube, and the copper tube is difficult to cool after heating, which leads to scalding.
Q:Can the electric heating wire in the quartz tube be replaced by an electric tungsten wire?
Recommendations should not be arbitrarily replaced, it is best to consult the quartz tube manufacturers, the replacement process required in strict accordance with procedures for operation, safety first! I have found you an infrared heating tube with a tungsten filament. I hope it will work for you: tungsten filament is placed in the quartz shell, and the filament is designed and made by the filament so that the luminous spectrum of the filament is in the range of 2400-3500K.
Q:What is quartz tube for?
Good light transmission performance of quartz glass in the ultraviolet to the infrared spectral band has good light transmittance, visible light transmittance is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance is higher than 80.
Q:Comparison of micro crystalline quartz tube grill with copper tube grill
Conclusions compared the main difference grill heating and cooling speed of electricity per minute for 3 minutes (barbecue) cooling quartz tube has high corrosion resistance and anti explosion, long-term water vapor, smoke not aging, long service life.
Q:Heater heating mode: quartz tube heating, ceramic heating, far infrared heating, halogen tube heating, I do not know the kind of heating method.
The far infrared radiation type electric heater comprises a quartz tube heater, a halogen tube heater, a ceramic reflecting heater and a plate shaped far infrared electric heaterQuartz tube electric heaterThe heating body is an electric heating wire and is worn in the quartz tube. Light is not suitable for use in the bedroom when there is light on the mission. This kind of electric heater is suitable for a small room of about 10 square meters, and the wholesale price is about 130 yuan. Because the heating wire oxidation and other reasons, has not seen.Halogen heaterHalogen tube is a seal type luminous heating tube, filled with halogen elements. By contrast, what brand is good?. Because it is luminous, heat dissipation, not suitable for bedroom use. It applies to 12 square meters of rooms, priced at between 100~200 yuan.
Q:Is the heater good for quartz tube or electric heating wire?
The best heating element is PTC ceramic, but each heating body has its own shortcomings. If you choose between the quartz tube and the hot wire, my advice is to select the quartz tube.
Q:Can quartz tubes be used in a vacuum tube furnace of 1300 degrees?
LTKC-5-12 vacuum tube furnace, quartz tube standard temperature resistance is 1200 degrees, programmable energy-saving tube furnace, LTKC-4-13 quartz furnace tube, temperature resistance can reach 1300 degrees
