Structure of glass sealing process sealing of electric heating tube

The compressive strength of the glass material is greater than the tensile humidity. Therefore, when the structure is designed, the glass is subjected to compressive stress. The typical sealing structure, the sealing of this structure, when the electric heating tube is cooled, the metal at the end of the tube can be Free contraction produces a bending moment at the interface of glass and metal. Because the two sides are symmetrical, the moments cancel each other out and the sealing is reliable.
