Glass tubing for sale’s mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance, and other properties have been greatly improved and can be widely used in chemical, aerospace, military, home, hospital and other fields, it has good extension value and social benefit.

Eliminate permanent stress and structural imbalances in glass tubing for saleat the time of manufacture. Glass tubing for sale is a poor heat conductor. When the product is formed, there is a temperature difference between the surface layer and the inner layer during the cooling process, this temperature difference from the surface cooling to room temperature, the inner layer continued to reduce temperature contraction, by the surface layer to create tensile stress, at the same time, the surface layer to produce compressive stress, permanent. The size and distribution of the permanent stress caused by the thermal process are not uniform across the parts of the product, thus affecting the glass tubing for sale strength and even breaking down due to stress concentration. Annealing eliminates the harmful tension in the glass tubing for sale and prevents the creation of new stresses. When the glass tubing for sale is heated or held to the annealing temperature after hot forming, the original stress is relaxed and removed, and then slowly cooled below the strain temperature, after the glass tubing for sale has fully entered the rigid body state, the temperature difference between the inner and outer layers produces only temporary stress. Due to the large viscosity of certain properties and functions of glass tubing for sale in the transition temperature range, the structural particles move slowly, so that their properties do not reach a temperature-consistent equilibrium, performance changes due to slow equilibration in use and therefore should be maintained at annealing temperature for sufficient time.
