Flow sight glasses type 520A

SHORT DESCRIPTION - HIGH-PRESSURE FLOW SIGHT GLASS FITTING TYPE 520A with ANSI flange connection 

The ACI high-pressure flow sight glass fittings of Type 520A have a solid casing that is manufactured of various materials, starting with high temperature constructions steel P250GH (1.0460), as well as stainless steels such as 1.4541, 1.4571 or acid-resistant special steels such as 1.4539. According to the pressure level, flanges according to ASME B16.5 are welded on and tested as part of the AD2000 guideline. On request, other materials such as nickel-based alloys like Hastelloy can also be supplied for the greatest wear. The fittings are usually made with two viewing windows, which makes it possible to observe the processes from two sides, as well as an illumination of the process medium.

The standard model has a sight glass manufactured specially for your use, made of thermally hardened borosilicate glass 3.3 or highly temperature-resistant quartz or sapphire glass. The sealing is ensured using flat seals selected especially for your use, according to temperature and chemical load, for example made of graphite (novaphit MST XP) or mica-based seals.

Due to the solid body, our flow sight glass type 520A can be equipped with test connections for measuring instruments or additional process connections (e.g. internal thread) on request.
