Applications

Thick wall quartz glass tube is widly used in furnace tube,instrumetation,semi-conductor,electric light source,machinery,and outher industries.

Q: How can the quartz glass tube be butted with stainless steel?: The best way is a stainless steel tube with screw thread connected with the quartz tube that a stainless steel tube, quartz tube can be just inserted into the stainless steel pipe, the equivalent of our usual locking connection, take a O ring buckle, fits in a quartz tube, a locking buckle take, can withstand the pressure bearing quartz tube

Q: What are the differences between carbon tubes and halogen tubes?: The halogen tube is a vacuum heating tube with tungsten wire placed in the quartz tube. The brightness of the halogen tube is brighter. The quartz tube is only a high temperature resistant glass tube, and the glass tube on the outer surface of the halogen tube is a quartz tube.

Q: What is the difference between the performance of the quartz ozone tube and the ceramic ozone tube?: Use a ceramic discharge tubeCeramic discharge tube is one of the most commonly used method of northern manufacturers, the use of ceramic plate ozone generator is low cost, ozone machine price is relatively low. But it is a short time, and low concentration ozone generator, the sterilizing effect is not ideal.

Q: Electronic energy saving heater and quartz tube heating rod: A heat pump is used to transfer heat from cryogenic objects to high temperature objects through a refrigeration system. Because of the basic structure of the system, the amount of heat released to the high temperature object is always greater than that used in the process.

Q: Quartz heating tube and carbon fiber, which saves electricity?: Environmental protection comparison: the metal tungsten in the quartz heating tube is a non renewable resource, and the carbon fiber wire is environmentally friendly material, renewable and inexhaustible. The waste carbon fiber thread will not pollute the environment.

Q: What are the defects of the ceramic heater and quartz tube heating?: PTC heater is almost perfect, it has no other heater, thermal energy conversion rate is high, the insulation degree of Grade A, long service life, the most important also comes with constant temperature function, not dry or burned because of overheating protection device failure, PTC heater will automatically control the temperature in a certain range, do not let the temperature rising.

Q: How do I distinguish the sterilizing cabinet from light wave disinfection and quartz tube disinfection?: Because of the rapid heating rate, the light tube can be instantaneously illuminated, while the quartz tube has a slow heating rate. The light of the quartz tube is dim, and it is slower than the light speed for a few minutes.

Q: Quartz tube resistance to high temperatures, where is the difference?: We are usually fused quartz tube, and divided "de hydroxyl" and "no hydroxyl" two kinds, the ability to remove hydroxyl nearly 1200 degrees Celsius, do not take off hydroxyl should be low 50~100 degrees celsius.Purely by appearance, it is difficult for professionals to distinguish.

Q: Will the heater explode?: The general electric heater adopts the quartz tube to heat up. It is to wear the resistance wire in the quartz glass tube, two end are not sealed, therefore the quartz glass tube can not damage (unless man-made interrupts).

Q: Does the oven quartz tube light up properly?: The oven will be heated and lit when it does not reach the set temperature. When the set temperature is reached, the heater will stop heating (out).

We are established by a team of senior engineers experienced in the processing of quartz glass, artificial crystal and mono-crystalline silicon products. We have rich technical force and utilizes first-class equipment. Having implemented a digital management system that extends to all production processes, we use inspection instruments that lead the domestic quartz glass industry. We have obtained the certification of ISO 9001:2000 and ISO 14001:2004
