Type 391 - PN14/40
CIRCULAR SIGHT GLASS FITTINGS TYPE 391 WITH WELD ADAPTED TO THE PIPELINE
SHORT DESCRIPTION - CIRCULAR SIGHT GLASS WITH WELD ADAPTED
The ACI tank sight glass Type 391 is a round tank sight glass intended for welded installation on an existing pipe or small pressure vessel.
The sight glass window is made from our high quality borosilicate glass according to DIN 7080, which has proven its reliability in most of our tank sight glasses. Alternatively, for elevated temperatures, we use high performance glass materials like quartz or sapphire glass.
For sealing we apply the same high quality flat gasket materials we use in most of our sight glass devices. We can offer universally applicable aramid fibre gaskets C4400 of the KlingerSIL brand as well Frenzelit novaphit MST. In addition to the full product range of these manufacturers we also offer special materials like Garlock Gylon or elastic materials like NBR, EPDM or silicone.
The specially adapted connection allows the sight glass Type 391 to provide a comparatively large window diameter. To ensure full compatibility with your existing piping and process, we offer Type 391 in a wide range of steel and stainless steel alloys like 1.4571, 1.4404, P265GH, as well as special alloys like Hastelloy or Duplex steel.
