Hello again. I'm working on a spreadsheet to aid my coworkers in sizing a Lube Oil System as per API 614 6th editions, and one of the requirements is that all gravity return oil lines must be at most half full.
So, what I've been trying to do is to determine what is the flow that could run...
Hi, I'm designing a bolted joint for the first time and Shigley's fasteners chapter was recommended to me for a good starting point.
I'm not writing the entire demonstration, but in the end, we have the following formula to calculate the bolt stiffness:
Which Ld and Ad are the bolt unthreaded...
Hello.
I work with drive-pump trains that usually have API 614 lube oil systems (LOS) installed. Those LOS always have an oil return pipeline that works only with gravity, and this return line have quite a few temperature gauges + thermowells to check how hot the oil is leaving each equipment...
I'm currently working on a seawater piping service and I need to selected the proper gaskets to avoid corrosion due to seawater in contact with super duplex steel.
For seawater, I was told that the "rule of thumb" was to always use PTFE as a filler for spiral wound gaskets, since graphite...
Hello!
Our engineering team is developing a "API 610 guide for beginners", in which we're trying to make it even easier for someone new to this area to understand the standard's requirements.
One point that got us confused were items 6.4.2.1 and 6.4.3.6 (from API 610 12th ed), which says about...
Hello,
I'm designing a lube oil reservoir as per API 614 guidelines, but one characteristic is puzzling me. In API 614, 1.3.6.2.6 says that "[...] free surface of oil in the reservoir shall be a minimum of 60 cm² for each liter per minute of normal flow".
I tried checking another literature...
Hello, I'm looking for a accelerometer model which has 4-20 mA + HART output, suitable for Zone 1 and 2, but with INMETRO certification (legal reasons).
I tried looking in Bently Nevada's, Emerson/PCB's catalogues and some general Google search, but it seems I'm out of luck, hardly any of them...
Hi,
I'm working in the instrumentation department, and we need to set the alarm and trip point of a centrifugal pump. I'm having trouble with the high pressure trip value.
According to our pump's curve, the highest discharge pressure would be at shut-off head (348 m) with +5% of tolerance...
