Tempered Borosilicate Glass Cylinders — 360° View

Tempered Glass Cylinders , utilized in 360° view sight flow indicators, combine high chemical and thermal resistance with the strength and visibility needed for demanding industrial applications.

Borosilicate glass , known for its low thermal expansion coefficient, allows these cylinders to withstand temperature variations and aggressive chemicals without compromising integrity.

The tempering process further enhances their durability, making them ideal for observing fluid dynamics in real-time from any angle, a crucial feature for processes involving hazardous or high-temperature fluids.

Do's and Don'ts - Tubular Gauge Glass

Warning: Failure to observe the following Do’s and Don’ts can result in glass breakage and an explosive release of pressurized system contents and flying glass particles. DO NOT work on any gage until you have carefully read these warnings and instructions.

Do’s - Tubular Gauge Glass

• Do Inspect the gage glass daily, keeping maintenance records, and conduct routine replacements.
• Do Install protective guards where necessary to protect personnel.
• Do Verify that the tubular gage glass, gland, nuts, packing, etc. are the correct size and type before installing.
• Do Examine gage glass for damage and seals for hard deposits and tears.
• Do Remove all deposits from the seal areas, the glands nuts, glands (where used) and use new packing before installing a tubular gage glass.
• Do Protect the outside of the gage glass from sudden temperature changes, such as drafts, water spray, etc.
• Do Ensure that system is protected by safety shut-off system (e.g. safety ball, check).

Don’ts - Tubular Gauge Glass

• DO NOT have glass-to-metal contact.
• DO NOT subject gage glass to bending or twisting stress.
• DO NOT allow the gage glass to contact the bottom of the packing gland.
• DO NOT bump, impact, or scratch the glass.
• DO NOT reuse any tubular glass, packing, or seals.
• DO NOT use glass that is scratched, chipped, or otherwise damaged. Used glasses may contain damage and are poor safety risks.
• DO NOT exceed the glass or gage manufacturer’s recommended working pressures or maximum recommended gage glass length.
• DO NOT tighten gland nut and packing beyond gage manufacturer’s recommendations.
• DO NOT operate gages unless gage valve sets are equipped with drain vent and safety ball check.
• DO NOT attempt to clean glass while the unit is in operation. Cleaning should be done without removing the gage glass.
• DO NOT attempt to inspect the glass, adjust tie rods, packing nuts or glands, inspect or tighten other fittings without isolating the gage from the pressure vessel and opening the drain vent.
• DO NOT weld, impact, or sandblast in the gage glass area without protecting the glass
