Spiral Welded Pipe for Oil and Gas Pipelines 1

[Francesb]

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 Lawson, C Duncan, RS Treseder; Corrosion ’87 Paper 52.
I am particularly interested in experiences of de-watering spiral welded pipe by pigging and any corrosion problems specific to this type of pipe.
