Tubular sight glass type 670 PN 16Intermediate flange design for flanges acc. to DIN EN 1092-1 USAGE Tubular sight glasses of type 670 are used to observe the level and flow in pipelines. They allow for reliable 360° monitoring of the function and performance of individual devices as well as complete systems. The tubular sight glasses of type 670 are designed for installation between flanges according to DIN EN 1092-1, PN 16. Gaskets should always be used that fit the sealing surfaces. The screw material should be chosen to be equivalent or superior compared to the flange material. Whenever possible, both the screw thread and the screw head should be provided with a suitable lubricant to ensure even pretensioning and easier assembly. Tubular sight glasses must be installed in such a way that no pipe forces (tension, pressure, torsion), vibrations, or pressure surges can affect the fitting. 10112025 - Subject to technical changes and errors!
