FRP sight glass (also known as sight cup) is available in two structural types: cylindrical glass barrel type and straight-through bidirectional viewing type (four-way sight glass). Featuring an innovative structure, excellent sealing performance, high transparency and easy installation, this product is acid-resistant and anti-corrosive. It is widely applied in industries including chemical engineering, electric power, pharmaceutical manufacturing, pesticide production, dyestuff processing, smelting and sewage treatment.
2. Main Applications of FRP Sight Glass
Sight glasses are installed in industrial production facilities for petroleum, chemical engineering, chemical fiber, pharmaceutical, food and other sectors. They enable real-time observation of the flow and reaction status of media such as liquids, gases and steam, serving as indispensable fittings to guarantee stable normal production.
