Thanks, Matt. I did find this interesting NASA study, but it had some unique design conditions so I couldn't draw the most applicable conclusions. It also referenced ISO-13732-3, but I don't have access to that code. In my (limited, 6 years) experience in power plant engineering, I haven't...
I'm aware of OSHA requirements to insulate hot piping (generally above 140 deg F) for personnel protection, but I can't seem to find any reference about a lower limit. Is there a code or industry practice for cold piping personnel protection? I imagine touching a pipe containing a fluid at...
I found that I was creating a Cartesian product. Basically, the joins and order of my query (I was looking for EquipmentType in tblReqDoc that matched those in tblProjectEquipment, instead of vice versa) caused 4 records for each of the 103 matching records in tblReqDoc. Or so I think...
Hi all,
I'm building an access database to track documents required and received at different stages of a project. The query I'm designing is intended to create a record of the Equipment Type, Equipment Tag, and Document Type that was submitted with bid. Should be a pretty simple query, but...

Hey all,
I'm in a bit of a pickle trying to find 18" Balancing Valves on the discharge of Chilled Water Pumps. Not only can I not find any above 12" from the standard valve suppliers (Crane, Velan, etc.), but I've also been told that they would be very expensive and large (space is tight)...
