58 pieces of tubular sight glass type 620 were sent on a journey.


We, the ACI Industriearmaturen GmbH, manufactured, assembled and tested 58 pieces of our pipe sight glass type 620 for one of our plant designers in a very short time. The tubular sight glasses made of stainless steel 1.4571 (F316Ti) are designed for an operating pressure of 16 or 10 bar. Due to the combination of PTFE seals and the borosilicate glass 3.3 glass cylinder, the tubular sight glasses can withstand a lot. Thus our sight glasses can fulfil their new tasks qualitatively, safely and reliably.
