SG type pipe and vessel sight glass
SG-type pipeline sight glass is a direct reading instrument used to monitor and observe the flow of the medium in the pipeline. It is installed on the pipeline in the form of flange or thread, and the flow of the medium in the pipeline can be truly observed through the sight glass. As one of the main accessories on the industrial pipeline device, it is suitable for petrochemical, electric power, pharmaceutical, environmental protection and other fields. Through it, the liquid flow reaction in the pipeline can be observed at any time to avoid accidents in the production process.
Technical advantages
SG type pipe and vessel sight glass is simple to install and easy to use. In view of the situation that the light is dark and the transparent liquid is not easy to observe, our company has installed a floating ball in the table cavity to make the liquid flow situation intuitively and accurately.
SG type pipe and vessel sight glass conforms to the HGS standard of the Ministry of Chemical Industry of China, and can be manufactured according to the special specifications provided by the customer according to the customer's requirements.
