Product Description

High Pressure Resistant Aluminosilicate Reflex and Transparent Level Gauge Glass Sight Glass

Aluminosilicate glass is a kind of alkali-free pressure-resistant glass. Glass mirrors cast with alkali-free aluminosilicate glass have excellent high-pressure resistance and are special glasses for various boilers, high-pressure reactors, petrochemicals and submarines. It has good chemical stability, electrical insulation, bending strength and high-pressure resistance. Its bending strength is 2-3 times that of borosilicate glass. Our company is a highly specialized manufacturer of aluminosilicate glass in China! Aluminosilicate glass is composed of RO-AI2O3-SiO2, where RO represents divalent metal oxides such as magnesium oxide, calcium oxide, barium oxide and zinc oxide. Because it does not contain alkali metal ions, it is called alkali-free aluminosilicate glass.

Applications

1.Chemical reaction equipment: Corrosion resistance and thermal shock resistance

2.high pressure steam system: Strong pressure resistance and long-term stability

3.Medical cleaning equipment: High cleanliness, low precipitation
4.Oil pipeline monitoring: Resistance to impact and medium erosion
