    Spiral Welded Pipe for Oil and Gas Pipelines

    Thank you for your comments. The client we were working for was determined to use spiral welded pipe. I think once the costs of producing this type of pipe to NACE MR0175 are accounted for it pushes the cost of spiral welded pipe up from the prices quoted to make it a less attractive choice.

    Corrosion Probes

    Are you using carbon steel for the pipeline? For sweet service you would probably only consider corrosion probes if you were expecting the gas to be wet and containing CO2 or chlorides as Hush said. There is also a cost element, it's much cheaper to include corrosion probes at the design stage...

    I am looking at a wet gas pipeline

    CARBURIZE has given the a basic corrosion rate formula which is in DeWaard & Lotz, prediction of CO2 corrosion in carbon steel, Paper 69, NACE Corrosion '93. It's a good first pass, but there are correction factors and modifications that can be made to this. Lots of the Oil and Gas operators...

    Spiral Welded Pipe for Oil and Gas Pipelines

    Has anyone had experience of using spiral welded pipe for either sweet or sour oil or gas pipelines (API 5L X52, X60 and X70 specs, some produced to NACE MR0175)? I am looking for case studies and so far have found only "Pipeline Failures in the Grizzly Valley Sour Gas System"; VB...
