High-pressure vessel flange sight glasses and sandwich flange sight glasses are named high-pressure vessel flange sight glasses in the Ministry of Chemical Industry's standards. Due to the influence of construction technology, this construction method will embed two flat flanges and clamp a layer of glass. This design is often called a flat flange sight glass; because its laminated glass is fixed by a flange, it is also called a sandwich flange sight glass.
Flange mirrors have small equipment installation dimensions, low torque required for driving, simple and efficient operation procedures, and very good flow regulation and sealing performance when closed. Flange sight glasses are mainly used in large and medium specifications and in industries involving medium and lower working pressures.
The material for replacing flange mirror gaskets should be corrosion-resistant and heat-resistant PTFE sheets. During the installation process, in order to solve the problem of convex surface and gasket and ensure the appearance quality, we should conduct a detailed appearance inspection to avoid axial grooves and scratches, and the rubber gasket should be flat and accurately positioned.
The flange sight glasses is a device used to observe the material status inside containers and equipment. It is a complete accessory. We must check it regularly to promptly discover any problems it has and solve them in a timely manner.
