what kind of experiences, good or bad?
do spares really interchange between the two?
example would be the Summit 2196 vs. a Goulds 3196.

doing a quick sanity check here.
we need to restrict the flow for a given situation. there is concern that we may not be able to adequately clean between batches if we use the typical restriction orifice and so we were considering reducing the line size.
so for a given restriction of 100 gpm...
an engineering firm is proposing PSD/PSV combination with the rupture disc (PSD) under the relief valve (PSV).
their planning to set the PSD less than MAWP and have the PSV set at MAWP.
i thought it was an ASME issue to have them set at the same pressure but am having trouble finding it and it...
we are replacing some sulphuric acid piping and some areas use plastic flange covers and others do not.
i prefer to install correctly (proper torque, alignment, etc.) and not have spray protection covers. i have also seen these hold up rainwater or small drips and fail bolting and then you...
An A&E firm is proposing using well water circulating through a jacketed vessel and applying 30 psig steam to an exchanger to heat the well water up to 180°F.
This seems too high. I apologize for the post but it is opening day for Michigan's deer hunting and everyone I'd normally contact is in...
We are being requested by corporate to review sizing rupture discs for the event of air/solvent vapor explosions in our tanks.
We have quite sophisticated nitrogen purging and procedures to prevent this event and have never had a problem. We typically use Layer Of Protection Analysis to...
Sorry but the advanced search function is not working.
We are having trouble with a pilot operated valve in steam service. It appears that we do not have adequate pressure on the system to pressure up the dome section of the valve.
Has anyone had trouble with turn-down of operating pressure...
are there any web-based pipe stress calculations using excel out there?
i need to calculate a torque associated with a system growing due to thermal expansion and want something that will step me through the calculation methods.

We use mineral oil (Chevron Superla White Oil) in a seal and are having failures that are being attributed to too high a viscosity.
The seal manufacturer has recommended a "lower" viscosity. I would like to get away from using phrases that the viscosity is "too high" and don't go "too low" and...
I am familiar with A333 piping for low temperature service (to -50°F) and we have some in an older part of the plant for a syltherm xlt system. Unfortunately, we no longer have a specification for it on site.
What are the differences between the various Grades of A333? What criteria is used...
We typically install weathercaps to prevent snow/ice/bird nests, etc. in the discharge of relief devices as well as install the discharge piping with a weep-hole or drain.
I cannot find any reference to caps being required but have seen many on LPG storage tanks etc.
Is this a good design...
