ASME/ANSI Sight Window: Glass Fused into A105 Steel Housing
 
  • Housing Material: A105 Steel
  • Window Material: glass (borosilicate available with Duplex stainless steel housing)
  • Temperature operating range: 0 Kelvin to 300C
  • Pressure safety factor: Minimum 1.25x
  • Thermal shock resistance: Excellent
  • Impact resistance: Excellent
  • Leak Rate: Equivalent to the permeation rate through glass (~zero)
  • Chemical resistance: Excellent for solvents, must be tested for specific acids and corrosives

All Rayotek ASME sight window metal housings are CNC machined, not cast, to exacting standards. Metal and window materials for all of our sight windows are traceable and certified back to their raw material sources to insure the highest, repeatable quality and reliability.

A105 Steel ASME housing with fused borosilicate glass window:

Rayotek A105 Steel/fused borosilicate glass ASME / ANSI sight windows are rugged general use steel sight windows for a variety of applications where corrosion is not a concern. For piping and chambers for furnace, incinerator and heater windows. Rayotek ASME / ANSI fused glass sight windows are so robust that even when cracked from mechanical damage they continue to seal and protect against release of pressure.

All ASME products are Built To Order, Please contact us directly for a quote.
