Borosilicate Transparent Gauge Glass

Transparent type is also manufactured from “extra-hard” borosilicate glass. The surfaces on both sides are finely smooth and  ensure optimal transparency.

A) One is as same with reflex Gauge Glasses,use molds to make the semi-finished products, afterwards, ground and polish the two side to ensure optimal transparency. By this manufacturing technique, the definition isn’t good.

B) The other manufacturing technique is made of High Borosilicate sheet of 17mm thickness, cut the glass sheet according the detailed size and polish the side face for the smooth. This manufacturing technique glass is very clear, but the goods cost is higher.

It can be used with all media at service conditions up to 6 MPa and temperatures up to 430 °C.

• Material: borosilicate glass

• Surfaces:polished;

• Lateral Surfaces:plain moulded or ground;

• Width of sealing surface:30-34mm;

• Tensile bending strength

• Standard: ≥ 150 N/mm²      High Pressure: ≥ 180 N/mm²

• Compressive prestress

• Standard: ≥ 80 N/mm²       High Pressure: ≥ 100 N/mm²

• The thermal toughening increases the tensile bending strength by a factor of 2 at least. That guarantees the safety demanded of level gauge glasses according to DIN 7081.

• Auxiliary service: Customer logo or production date can be printed.
  

According to customer needs, non-asbestos gasket or graphite gasket can be matched with the product.
