The quartz glass tube forming process is a hot forming process for producing quartz glass tube by using high-temperature fused quartz by a separate blowing method, a drawing method, a pressing method and a blowing and pressing method. A furnace is used to heat the glass during the thermoforming process of the tube. Processing fused silica in a thermoforming process requires a great deal of experience. Because of the high melting point and viscosity of fused silica glass, the processing temperature range for this material is narrow. If the processing temperature is too low, the fused quartz cannot be fused; if the processing temperature is too high, the fused silica becomes too soft, is nearly liquid, and is extremely prone to evaporation into soot. The quartz thermoforming process requires an annealing treatment (or multiple intermediate anneals) to reduce thermal stresses. If improperly handled, the glass may fracture at any time.

In the process of forming the quartz glass tube, a flame gun is used to heat the part of the quartz glass tube to be formed, so that the part of the quartz glass tube is softened, and the quartz glass tube is conveniently subjected to a separate blowing method, a drawing method, a pressing method and a blowing and pressing method to be thermally formed.
