Just like any material, it will have a pressure tolerance per square inch. For Most high pressure boilers the glass will be very small, often less than 1 square inch. This means that multipule gauges will be used together, one ontop of the other. They will be arranged in stack, collectivily known as a Boiler Gauge Glass, with each glass only showing part of the level in the drum.

What happen in boiler gauge glass if steam side valve isolate during charge condition?
If steam side valve isolate during charge condition, the water level goes up inside the gauge glass and shows a false level in it. Note that , the water side valve must have opened at the same time and drain valve is in closed condition.
What is unbreakable glass?
glass that can't break!
Is glass a smart material?
Yes, just don't break it.
What device or instrument is used to measure air pressure?
If you're asking about a tool to measure the air pressure in a car tire, that is called a pressure guage.If you're asking about a scientific instrument to measure atmospheric air pressure, it is called a barometer.
How many years does it take plastic to break down?
hundreds, glass takes thousands!!but glass is just fused sand and can be returned to its natural form by simple crushing. plastics are complex hydrocarbon polymers.
Why steel ball in boiler gauge glass?
Steel ball is used in boiler gauge glass to prevent overflow of water when ever gauge glass is broken..
Why is a ball given in the gauge glass?
incase if boiler gauge glass breaks...this steel ball fits on the tube and it prevents of leakage of water.

Why gauge glass burst?
A gauge glass may burst depending on the gauge itself. High temperature and pressure situations may cause the glass to burst.
How far above the lowest permisseble water level is the bottom of the gauge glass in a fire tube and water tube boiler?
3inces
Why doesnt the pressure of atmosphere break windows?
Pressure in the atmosphere doesn't break windows because there is the same pressure on both sides of the glass. Windows can break if there is a big difference on one side compared with the other.
How to adjust the zero error in pressure gauge?
step-1:remove the pressure gauge from the equipment when machine is in off condition. step-2:remove the cap and glass of the gauge. step-3: remove the needle of the gauge with a needle puller( a special tool ) step-4: place the same needle indicating zero. step-5: fix the glass and cap as usual. step-5: check(calibrate) the gauge on a dead weight tester with a master degital pressure gauge.
How does glass break?
When you apply pressure to glass, it can only resist a certain amount if force, do when the amount of pressure excedes the amount of force a glass can hold, it starts cracking from the inside, as if it were trying to bend, and eventually the sides collapse.
How many pounds of pressure does it take to break a car side window?
Since it would probably be tempered glass, 100lbs. of pressure.
Why does a thin glass bottle filled with fluid break when the cork is pushed down?
The pressure build up is too much for the thin glass to handle.
Why is glass easy to break?
Because glass is joined by covalent bonds in a rigid lattice so when pressure is applied like forces align and separate therefore making the glass shatter
