New gas service to existing homes as part of a larger project, from the meter bar we bored an over-sized hole [allow movement] through the foundation piped through it. The excess clearance was caulked for fire protection and to prevent any water ingress.
Someone brought it to my attention...
Hello All,
A new hot issue got thrown on the plate, having a tough start on how to tackle and would appreciate any help. I’m trying to calculate if the existing installation of a ‘surge header’ at a gas plant would handle a total plant upset condition – meaning if every valve lifted...
I've searched the web and really found nothing I could use for our application.
Currently installed is a 4" drain line, which needs to maintain a column of water to prevent air ingress into the system.
A typical 'P' trap or steam trap could not be use in our service - 1.) Due to location...
Can I calculate an actual flushing flow rate with a trend peak shape from an OS?
Assuming the peak as a triangle and measuring the duration in minutes between distance and top, then multiplying base line and peak to find a volumetric flow rate – g.p.m.
I’m trying to capture the flow during...
Dealing with 18” steam process line, temperatures of 1030F in reheat system. We are waiting for fabricated graphite pads to be installed, the expected delivery date will put us very much behind schedule.
Is there an alternative resolution or contingency action I could take to avoid such delay...
We came across a little issue with our process drains and are now forced to pipe a safety/relief valve to a common header in order avoid further damage. However in 'good engineering practice' this was supposed to be piped in order to avoid and undo stresses during operation with pipe travel. I...

We have some areas where the cooling water piping without any sliding supports or shoes. The iso. drawing calls for this inside the enclosures, I've looked in B31.1 and 31.3 but found nothing stating when not to use shoes or when acceptable. Again this is 6" cooling water piping (CS) with...
