Classification of Pressure Resistant Glass

Pressure resistant glass is a special glass for industrial pressure vessels, pressure equipment and other high-pressure places. It is widely used in petrochemical, steel, boiler and other enterprises. The pressure of professional pressure resistant glass is ten to one hundred times that of ordinary glass under the same specification.


 

According to different materials and processing methods, high-pressure glass is divided into medium and high-pressure glass, high-pressure glass and ultra-high-pressure glass

I medium and high pressure glass: this kind of pressure resistant glass is used for equipment with low pressure, such as pressure vessels in petroleum, chemical industry, electric power, etc.

Technical parameters:

Thermal stability (℃) ≥ 300

Bending strength (MPA) 200-220

Softening temperature (℃) ＞ 920

Expansion coefficient (/ ℃) 42-46*10-7

II high pressure glass: this kind of high pressure glass is used for high pressure equipment, such as nuclear power plants, aviation, military and other high pressure vessels.

Technical parameters:

Bending strength (MPA) 120-150

Softening temperature (℃) ＞ 800

Expansion coefficient (/ ℃) 32.5*10-7

Thermal stability (℃) ≥ 180

III ultra high pressure glass: this kind of high pressure glass is used for equipment with high pressure, such as high-pressure boiler, high-pressure reactor industry production testing equipment, supercritical extraction device and other high-pressure and high-temperature resistance test equipment.

technical parameter

Bending strength (MPA) 40-60

Softening temperature (℃) ＞ 860

Expansion coefficient (/ ℃) ≤ 5.4*10-7

Thermal stability (℃) ≥ 280
