The DN50 cross-type pipeline straight-through sight glass is one of the main accessories in industrial pipeline installations. It allows for continuous observation of the flow reactions of liquids, gases, steam, and other media within the pipeline, enabling production monitoring and helping to prevent accidents during operations. It is commonly used in production pipelines for petroleum, chemical, fiber, pharmaceutical, and other industries. Stainless steel pipeline sight glasses feature a compact installation size, low driving torque, simple and quick operation, as well as excellent flow regulation and shut-off sealing characteristics. In applications involving large and medium diameters with medium to low pressure, the sight glass is the dominant form of viewing device.

Our pipeline sight glasses are available in multiple models to suit pipeline systems of different diameters and pressures. The DN100 model is our flagship product, suitable for most industrial applications. Additionally, we offer other models to meet your specific requirements.
