Hi everyone,
I graduated with a degree in Mechanical Engineering recently and I now work at a nuclear power plant as a plant operator (started 2 months ago). Even though my company is going to teach me everything about operations and then some, I'll never have the opportunity to work with...
Hi folks,
I'm working on an application where I'm tying into a live pipeline and we're diverting some of the flow to storage tanks. The flow from the pipeline goes through a metering skid which has all the bells and whistles like PSVs going to closed drain drums, strainers, check valves, PD...
Hi,
I'm working on a project where the customer doesn't want any NPT connections at all so I have to change over all of my adapters to one piece units.
So before I had a 6'' 600# raised face (RF) flange tapped to 3'' NPT, in that I put a 3'' NPT nipple, and on the nipple I put a 3'' hammer...
Hi folks,
My company does Nitrogen-Helium leak testing as part of pre-commissioning of new oil and gas facilities. Basically we pressure up the system to 95% of the lowest PSV setting with a 99% Nitrogen and 1% Helium mixture and sniff flanges and valves for leaks. The Helium detector gives us...
Hi,
Wanted to pick peoples minds on Sour oils corrosion potential for Carbon Steel(CS) pipe. I know H2S can mess up CS and so can sour oil (no H2S, just >0.5% Sulphur content). But sour oil is only a threat when it is at high temperatures (200-500C) right? Am I right in saying that if the oil...
Hi Folks,
I've got a 6'' FMC positive displacement liquid flow meter as part of some piping that I have to pressure test with Nitrogen gas. Once we've held the pressure and start the blow down, I will be opening a vent downstream of the flow meter. I know that this is bad for turbine flow...
I have a pipeline operating at 500psi and 60m3/min. I’m connecting 3’’ frac iron (good till 12,000psi) to the mainline to draw oil from it. The iron connects to an 8’’ manifold which connects to 4x 400bbl frac tanks. This tank manifold is only rated for 120psi and all the tanks are open to atm...
Hi,
I'm working on a job where I'm pumping oil into a pipeline using a positive displacement pump. I need to install a PRV downstream of the pump to kick in at the pipes MOP and divert the product upstream of the pump in an overpressure situation.
When calling the valve people we work with...
Hi Folks,
I'm working on a project where we have a natural gas line that needs to be purged using Nitrogen gas. Can't use a pig because of different size pipes and can't use a cycle purge because of balloons (for lack of a better word) we have in the line. I've attached a pic, the balloons are...
Hi Everyone,
Been following eng-tips for awhile now and finally made an account to ask a question. Junior mechanical engineer here working on my first project. I'm working on a project where I have to pump 500m3 of oil(or any other hydrocarbon) from tanks into a pipeline operating at 500psi in...
