Gauge Glass Installation - Use and Care
DO NOTs
DO NOT use glass if it contains any scratches, chips, or any other visible signs of damage.
DO NOT reuse any tubular glass or glass packings.
DO NOT subject gauge glass to bending or torsional stresses.
DO NOT over tighten glass packing nuts.
DO NOT allow glass to touch any metal parts.
DO NOT exceed the recommended pressure of the gauge or gauge glass.
DO NOT clean the gauge or gauge glass while pressurized or in operation.
DO's
DO verify proper gauge has been supplied.
DO examine gauge glass and packings carefully for damage before installation.
DO install protective guards and utilize automatic ball checks where necessary to help prevent injury
in case of glass breakage.
DO inspect the gauge glass daily, keep maintenance records, and conduct routine replacements.
DO protect glass from sudden changes in temperatures such as drafts, water spray, etc.
MAINTENANCE
Examine the gauge glass regularly for any signs of clouding, scratching, erosion, or corrosion. The glass should be
inspected daily until the need for replacement becomes apparent. This will help establish the routine inspection
and routine replacement schedules.
CLEANING
Use commercial non-abrasive glass cleaners to keep glass clean. Use diluted acids such as Hydrochloric (muriatic)
acid when regular cleaners do not seem to work. Do not use wire brushes or any other abrasive materials which
could scratch the glass.
INSPECTION
Examine the surface of the glass for scratches, corrosion, chips, cracks, surface flaws, or nicks. To do this, shine a
very bright concentrated light at an angle of about 45 degrees. A defective glass will glisten as the light strikes
imperfections. Glass which appears cloudy or roughened, and will not respond to cleaning, should be replaced.
STORING
Keep gauge glass in original packaging until ready to install.
