Toroidal Ring.
Toroidal Ring.
(OP)
Hello Dear Friends,
Based on RP-521 there should be a Toroidal Ring to be installed on the vent-stack outlet which dischage hydrocarbon vapours specially Hydrogen.
Any one with experience with this device?
Any Vendor who can supply this?
Any help is highly appreciated.
Thanks.

Thanks a lot for the info.
The assembly you decribed can discharge electrostatic force?
Or we have to ground the tube?
Again thanks a lot for the feedback.

API 521 doesn't say that all H2-rich vent should have a toroidal ring. Instead, it simply informs the reader that a toridal ring was found (by NASA to be effective at preventing ignition due to static discharge. That's just information for the user to consider.
Personally, I don't have any experience with toroidal rings. instead, I always assume that a H2-rich stream will ignite (seldom do they not ignite) and include a snuffing steam connection to the tailpipe. Even if you install a toroidal ring, you ought to locate the tailpipe in such a way that it's safe if it does ignite.
In some cases it's probably a good thing that these H2 stream ignite when released. You don't want to form a combustible H2 cloud.
