Check Valve Erosion Problem
Check Valve Erosion Problem
(OP)
I am currently investigating a problem in which sand erosion is occuring in a multiphase (oil/water/gas & sand) pipeline.
Essentially sand is causing erosion in the body and downstream of a dual plate check valve. I am looking for an alternative check valve design with a good record of erosion resistance in sandy service.
Any ideas?
Cheers,
Neil

We have supplied a lot of valves to salt kavern oil storge facilities including oil, sand, water service with special coatings.
Send your application to hgustorf@noreva.de if you like.

They have many check valves installed in the flowline of oil / gas production units.
You should be able to reach them via their website.

I've had pretty good luck getting rid of check valves that were placed on wellhead tubing lines "because that is the way we've always done it" when the company had no intention of ever flowing casing and no credible source of backflow.
If you have to leave the valve, you should look hard at the suggestions above.

Can you tell us a bit more on pressure and temperature?
If your seats are not damaged I do not believe a non slam check valve will solve your issue (also they will cost your customer a fortune), I am thinking more in lines of a rubber lined back flow preventor.
