The glass tube sight glass consists of connecting flange, glass tube, extension bolt and sealing gasket.The glass tube fixed flange clamps the glass tube, and is fixed with the extension bolt. The pipe is connected with the flange through the connecting conduit, thus forming a whole glass tube tubular.
Glass tube sight glass can observe the flow of liquid, gas, steam and other media at any time, is an indispensable accessory to ensure normal production.Has reasonable structure, convenient operation, good sealing performance, high working efficiency, alkali resistance, acid resistance, non-toxic, model design and beautiful strong wait for a characteristic, is widely used in chemical, pharmaceutical, metallurgy, dye, food, sugar, wine making, ceramics and environmental protection industries, drainage or worse before the solid flow, cooling water and other liquid tube to observe the liquid flow on the road.
Scope of application:
1. chemical industry, petrochemical production of weak corrosive materials, such as: water, ammonia, oil, hydrocarbons, etc.
2. Corrosive materials in chemical production, such as: caustic soda, concentrated dilute sulfuric acid, carbonic acid, acetic acid, ester acid, etc.
3. Cryogenic materials in refrigeration, such as liquid ammonia, liquid oxygen and various refrigerants.
4. light industrial food, pharmaceutical production of health requirements of materials, such as: beer, beverages, dairy products, medical supplies, etc.
