Depends what code you're referring to. Using the word "pipeline" defaults me to DOT (USA) which is pretty strict and most likely doesn't allow it. See here for 49 CFR: http://www.phmsa.dot.gov/hazmat/regs

Don't forget to put up start up strainers if you are putting anything else in besides the pump to keep garbage from damaging the impeller and to recheck alignment after its been running at temperature.

I have been working on a project where there was no provision for thermal expansion with a multistage centrifugal pump. It doesn't take very much expansion for enough forces to be exerted for shaft misalignment. With just a little deflection in the pump, your bearings and shaft WILL prematurely...
Vertical launcher, I can see. Vertical receiver, I can see to be a total mess, especially if you're using a pig to clean your lines.

Yep. Maybe several hundred is a bit of an exaggeration but a couple hundred isn't. They meter their steam on every cyclic well and selected orifice plates as the technology to do it. I've decided to take a more pragmatic approach and manually control the valve to 100% and measure the output...
I know the problem is a bowed plate (actually several hundred of them). There is an inherent problem with the original design that I'm also charged with fixing. I'm not trying to compensate for the flow rate. That's next to impossible, especially what zdas04 mentioned. I'm trying to solve a...
Is there a correlation that can determine the error in an orifice plate reading after it has warped? For example, if I use an orifice plate to measure steam, then syrup (or heavy crude) and the viscosity of the syrup warps the plate, is there a method to determine that the flow rate is within...
This was a very interesting project. Its been done for a while but I wanted to post for future questions.
The results that I found was that (according to RP579 - Fitness for Service) fatigue failure of the weld is directly related to the quality of the weld. Stress concentrations due to slag...
What is the difference between AGA 3 and API 14.3? After reading the "Scope" section, it seems that they are pretty much the same.
I was told (by a vendor) that the difference is that AGA 3 is for custody transfer and API 14.3 is for non custody transfer.
Any insights?

I am being asked to compare the lifespan of a 6010 x 7018 weld with a 6010 x 6010 weld in a pipe that will thermally cycle once every other week.
Where is a good starting place for evaluating the two weld types?

I was looking at Cidra Sonartrac and sent an inquiry to Rosemount. I have a quote for the Sonartrac and a Magmeter with some super diodes that supposedly get coated in an emulsion service. I'm not going to hold my breath but since both vendors are willing to give me a demo to try...
I was lucky enough to visit the Micro Motion factory and play around with one of their demonstration devices. Essentially it had a reference meter with water running through it, a line where air was pumped into the line at adjustable flow rates and 'test' meter. For mass measurement, the meter...
That was my first question as well. There is a very high concentration of H2S in the crude so they want to limit exposure as often as possible. Its an established field so they don't want to spend a lot of money on additional infrastructure like vessels and other equipment that might IMPROVE...
That was I was thinking and afraid of. My experience has been Daniel LUSM which is expensive & was a pain to start-up. Is there such a thing as a cheap, reliable LUSM?
