Glass Products



Glass has excellent corrosion resistance in general but is attacked and dissolved in service by alkalain solution, resulting in thinning of the wall and premature failure or replacement. High alkalinity and high temperature increase the rate of attack.
LUKING-AR has excellent resistance to high alkalinity and high temperature which enables reflex type gage is adoptable to high pressure boiler aplications.
