What do you know about the sanitary stainless steel sight glass?
Publish Time: 2022-03-20 Origin: Site
sanitary stainless steel sight glass is a more general term. All sight glasses installed on pipes are called pipe sight glasses. Among them are glass pipe sight glasses, and cross-shaped glass plate straight-through sight glasses. The sight mirror is divided into swing plate straight-through sight mirror, floating ball straight-through sight mirror, impeller straight-through sight mirror, stainless steel sight mirror. According to the connection method, there are thread, flange, welding, quick installation, etc.

What are the precautions for using sanitary stainless steel sight glass?
1. Improve the material of sanitary stainless steel sight glass. Use the PTFE plate with corrosion resistance, aging resistance and high temperature resistance. When installing, the sealing surface and gasket should be visually inspected. There should be no defects such as radial grooves and scratches. The sealing gasket should be installed flat and accurate in position. There must be no deflection or center offset, and the contact is good to meet the requirements of use.
2. Strengthen the management of sanitary stainless steel sight glass production process indicators. Strictly control the outlet gas temperature of the pre-distillation tower at 120℃, the pressure is 1.765MPa, the outlet gas temperature of the first suction tower is ≤46℃, and the pressure is 1.765MPa to prevent over-temperature and over-pressure.

What should be paid attention to in the production of sanitary stainless steel sight glass?
In the process of urea production, in the medium and low pressure towers with sanitary stainless steel sight glass, due to the high working temperature and strong corrosiveness of the liquid, it is easy to cause damage to the sanitary stainless steel sight glass and the bottom plate of the sight glass to be deformed. In the process of installing the mirror glass, sometimes due to uneven force, it is easy to cause the mirror glass to break. If it is not found in time, leakage will inevitably occur after driving, and then the entire system must be shut down for hot wash replacement. This not only brings difficulties to the long-term safe operation of the system, but also seriously affects the efficiency of urea production.
