Asahi India Glass Limited, known as AIS, is a glass solutions and manufacturing company in India. It was established in 1984. It manufactures automotive safety glass, float glass, architectural processed glass, and glass products. It also provides consumer glass offerings in the form of Glasxperts and Windshield Experts.
The gauge glass on a boiler needs to be inspected periodically and replaced if it is seen to have worn thin in the vicinity of the gland nuts, but a failure in service can still occur. Drivers are expected to carry two or three glass tubes, pre-cut to the required length, together with hemp or rubber seals, to replace the tubes on the road. [1]
The company was formed by a JV agreement between the Labroo family, Asahi Glass Co. Ltd. (AGC), Japan, and Maruti Suzuki India Ltd. It is the largest Automotive glass manufacturing company in India and manufactures a wide spectrum of glass products including automotive safety glass, float glass, and architectural processed glass.
It is also frequently applied on magnetic sight gages. In this variation, the magnet is installed in a float that travels inside a gage glass or tube. The magnet operates on the sensor which is mounted externally on the gage. Boilers and other high temperature or pressure applications take advantage of this performance quality
Liquid-column pressure gauges have a highly linear calibration. They have poor dynamic response because the fluid in the column may react slowly to a pressure change. When measuring vacuum, the working liquid may evaporate and contaminate the vacuum if its vapor pressure is too high. When measuring liquid pressure, a loop filled with gas or a ...
Gauges for measuring pressure in the range 20–30 standard atmospheres (15,000–23,000 mmHg) have been built. [13] A 23-metre-tall mercury column is difficult to read and suffers from inaccuracies caused by different parts of the column being at different temperatures. A more compact mercury pressure gauge suitable for high pressure was built ...
The Pirani gauge consists of a metal sensor wire (usually gold plated tungsten or platinum) suspended in a tube which is connected to the system whose vacuum is to be measured. The wire is usually coiled to make the gauge more compact. The connection is usually made either by a ground glass joint or a flanged metal connector, sealed with an o ...
A high-integrity pressure protection system (HIPPS) is a type of safety instrumented system (SIS) designed to prevent over-pressurization of a plant, such as a chemical plant or oil refinery. The HIPPS will shut off the source of the high pressure before the design pressure of the system is exceeded, thus preventing loss of containment through ...
