I am not that knowledgable about pumps so if anything I say isn't correct feel free to correct me.
I have a centrifugal pump that is getting tiny holes in the impeller. I know this is due to cavitation. The pump is pumping much more than we need (its giving over 1100gpm when 950gpm is all...
Thank you all for your posts I really appreciate it!
zdas04 - What was your reasoning for liking the FlexSteel better?
brimmer - You said that you had used the composite pipe in gathering systems did you ever come across any problems with the junk that can get into the pipes from the...
The HDPE pipe being considered is from flexpipe( www.flexpipesystems.com ) we are just looking into it for our gathering system becuase of the reduced cost of construction and maintenance.
I guess a better way of phrasing my question is what the pros and cons of the HDPE pipe and what were the...
I am wondering if anyone out there has any experience with HDPE pipe in natural gas gathering. The vendors tell me that it can handle wet gas with hydrocarbons and potential for freezes but I am still skeptical. Also, the fitings worry me because they seem to rely simply on clamping pressure...
I asked this exact same question in the gas distribution engineering and got this link from dcasto. it was super helpful! Just download the programs and each allows you to model a little differently.

I have read that before and while they do give a lot of useful graphs they are only for specific compositions and they don't give the mathematical relation that they came up with to determine the hydrate temperature.
We are trying to cut costs by taking down a dehydrator but the concern is hydrate formation. How do I calculate the temperature at which hydrates will begin to form based on pressure and water content? This is for a natural gas pipeline.
I hav found some articles on hydrates and they all...
I just moved from my home in Missouri where I grew up and went to school. I moved away from all my friends who got jobs in St. Louis. But I have to say I don't regret it. I moved to New Mexico and while it took about 3 months I learned to really like it here. If you go in with a positive...
I revalidated the calculations and got an orifice size of 0.510in^2 for the 475psig PSVs and 0.220in^2 for the 1100psig PSV's. The sizes for the exisiting PSVs vary from size 1 to 2, how do I determine if the exisiting PSVs are adequate? What I am asking is based on the size how do I determine...
How do I determine if a PSV will still be at maximum relief capacity if reset? There are two sets of PSVs, ones currently set at 500psig and need to be reset 475psig and ones that are set from 1210 to 1290 psig and need to be reset to 1100psig. I also have a PSV that is set at 445 psig and one...
