Tubular flow sight glasses type 620A


BRIEF DESCRIPTION: TUBULAR SIGHT GLASS WITH BOROSILICATE GLASS CYLINDER FOR 360° PANORAMIC VIEW

 The heart of the ACI Pipe Sight Glass Type 620A is a borosilicate glass 3.3, pipe enclosed between two stainless steel or steel flanges. This design enables Type 620A to provide 360° observation and illumination of the process medium.

The standard version of the tubular sight glass Type 620A is supplied with flat gaskets made of pure PTFE or Teflon, but we also have novaphit MST and soft-material gaskets such as EPDM or NBR in stock. If our standard range of gaskets does not meet your requirements, simply contact us and we will select the perfect special material together with you.

As flange material we use the highly resistant quality stainless steel 1.4571 (AISI 316 Ti, X6CrNiMoTi17-12-2). These flanges are held together and supported by solid threaded studs to ensure the best possible service life of the valve.

For less demanding applications, our Type 620A tubular sight glass can also be supplied with P265GH flanges. Of course, it is also possible to use special materials such as Hastelloy alloys, duplex steel or other high-performance metals.

In small nominal diameters (up to 2 inches) our tubular sight glass type 620A withstands a nominal operating pressure of up to 16 bar without any problems, and up to 4 inches 10 bar is still possible without hesitation!

Since the flange, gasket and glass are precisely matched to each other, the tubular sight glass type 620A is almost completely free of dead space and is therefore well suited for applications that place high demands on cleanliness.

For use in industrial plants in which ongoing work must be expected, especially for installation under or near catwalks, we recommend the installation of one of our impact protection jackets. This simple additional option protects the glass tube against impact from falling parts or tools and you may save yourself an expensive repair or even a catastrophic failure of the plant!

Our tubular sight glasses are fully assembled in our workshop and subjected to a pressure test at 1.5 times the operating pressure. Maintenance after installation is usually not necessary.
