Sight glass fitting

sight-glass-fitting as rectangular or circular container sight glass

A sight-glass-fitting can be used to observe and check tanks like silos, storage tanks or pressure vessels. The exceptionally pressure and temperature resistant glasses allow you to see the inside of the tank for visual inspection. The container sight glasses from NieRuf come in two models: as rectangular or circular sight glasses. The rectangular sight-glass has one long side and two shorter ones. Thus it is often welded onto the tank in a vertical way, which allows you to keep an eye on the filling level. The circular sight-glass is used in silos or boilers. The round glass allows for a larger field of view. After welding the mounting flange, you should check whether the sealing area has moved. In this case, reworking might be required. The operating pressure is valid not only for the base frame and needs to be checked with the pressure device according to technical bulletin AD B9. Please contact us if you need further information.

Container sight-glass in different models: resistant due to high quality materials

The container sight-glass fitting comes with a high quality borosilicate glass DIN7081. This glass, including a C4400-Klingersil-seal, is flanged between mounting and cover flange using screws and nuts. Mounting and cover flange are made of high quality V4A stainless steel 1.4571 and 1.4541. The flange of circular sight-glasses can be made in nominal sizes DN25 to DN200. The rectangular sight-glasses-fitting can range from a length of 170mm to 930mm. Our container sight glasses can be used with liquid and gaseous media, feel free to contact us if you have questions about additional compatibility.

Depending on the model, they can be used in pressure vessels and pipelines with a maximum pressure of up to 16 bar (please check technical bulletin AD B9).
