extreemly smooth pipelines
extreemly smooth pipelines
(OP)
Anybody got a good reference for coating that can lower the absolute roughness for pipeline piping?
Normally i use 0.05mm (0.001 inch) for plant piping and 0.025 mm for new pipelines.
I have however heard that certain internal coating (epoxy?) can lower the roughness to as low as 0.005-0.01 mm!
Do anybody have a reference to a vendor for any such product?

I don't have the details with me today, but I did a Google search on "pipeline liner rehab" and found a picture at http

The epoxy coatings you talk about are a problem at weld seams. I've seen wads of the coating in downstream measurement equipment over time. I've been told that the problem happens when seams fall in the middle of sags and overbends. It is also a problem when you cut the pipe to get a short joint.
For a 40-inch line you could have someone in a pressure suit spray epoxy the line after the welds cool.

I'd also try coating companies like Balmoral Webco and Bredero-Shaw
