Sight glass is widely used in petroleum, chemical, pharmaceutical, food and other industrial production equipment in the pipeline, can always observe the pipeline in the liquid, gas, steam, lubricating oil and other media flow, play a monitoring production, to avoid accidents in the production process, is an indispensable accessory on the pipeline equipment.
Petroleum, chemical sight glass is made of steel lined with fluorine plastic, the sight glass is made of toughened glass, it can be used in strong corrosive pipelines, and the working temperature can be used between -29 degrees and 200 degrees. It plays the role of monitoring the production to avoid accidents in the production process, and is an indispensable accessory for pipeline installations.
