Key Features


Excellent Thermal and Mechanical Properties: It has a low thermal expansion coefficient of 3.3×10⁻⁶/K, which can withstand large temperature differences without cracking. At the same time, it has high mechanical strength and high hardness (Mohs scale 6-7), which is wear-resistant and impact-resistant, and can adapt to the harsh working environment of the boiler.


Super High Transparency: The transmittance is higher than 91%, presenting excellent optical performance, allowing operators to clearly observe the liquid level in the boiler. Even in low-light environments, it can ensure clear observation.


Diversified Size Options: It provides multiple size specifications such as 340 x 34(30) x 17mm, 320 x 34(30) x 17mm, and 280 x 34(30) x 17mm, which can be flexibly selected according to the model and size of the boiler, improving the compatibility of the product.


Scenario-Specific Solutions


Industrial Boiler Operation Monitoring

In the operation process of industrial boilers in factories and power plants, Optical Transparent Level Gauge Glass Strip Sight Glass For Boiler is installed at the designated position of the boiler. With its super high transparency and stable performance, operators can monitor the liquid level in the boiler in real time. Once the liquid level is abnormal, timely measures can be taken to avoid boiler dry burning or other safety accidents, ensuring the safe operation of the boiler and the normal progress of production.


Boiler Maintenance and Overhaul

During boiler maintenance and overhaul, this glass strip sight glass can help maintenance personnel clearly observe the internal condition of the boiler, including the accumulation of dirt and the state of internal components. Its high hardness and wear resistance ensure that it will not be easily damaged during the maintenance process, and it can still maintain good performance after multiple uses, providing convenience for boiler maintenance work.


FAQ


How to select the appropriate size of Optical Transparent Level Gauge Glass Strip Sight Glass For Boiler?

First, you need to confirm the model and size parameters of the boiler, especially the installation size of the level gauge. Then, select the corresponding size specification of the Optical Transparent Level Gauge Glass Strip Sight Glass For Boiler according to the installation size. If you are not sure, you can provide the boiler-related parameters to us, and we will recommend the appropriate size for you.


What is the service life of this glass strip sight glass in the boiler environment?

Under normal use conditions, the service life can reach 3-5 years. The harsh environment in the boiler, such as high temperature and pressure, will affect the service life. Regular inspection and maintenance can effectively extend its service life. It is recommended to check the state of the glass every 6 months.


Is this glass strip sight glass easy to replace?

Yes, the replacement process is relatively simple. First, turn off the boiler and wait for it to cool down. Then, remove the old glass strip sight glass and install the new Optical Transparent Level Gauge Glass Strip Sight Glass For Boiler according to the installation instructions. It should be noted that the sealing performance should be guaranteed during replacement to prevent boiler medium leakage.
