API 5LX-70 Spiral Welded Pipe
(OP)
Has the subject pipe been used with an alternate lcation factor, F = 0.80 in any cross country natural gas pipeline in the USA, Canada or Europe?

RE: API 5LX-70 Spiral Welded Pipe
Thanks. I am well aware of X70 DSAW pipelines made with F = 0.80 but have no info regarding spiral welded [helical submerged arc welded] pipe at the F = 0.80 alternative under Part 192. I know of some spiral welded X-70 pipelines at F = 0.72.
My personal experience with spiral welded pipe was years ago and it was not impressive (or better said highly impressive regarding its lack of quality seam welds). I expect that welding technology for spiral welded pipe did improve over the past 25 to 30 years though.
RE: API 5LX-70 Spiral Welded Pipe
I'm not so sure I would question the spiral, as much as I question the F=0.80. Personally. I think F 0.80 is pushing it too much. They don't even use that in the middle of the Saudi Arabian deserts where there is not even a fly to be found for 500 miles. Gives me nightmares about BBQd campers.

RE: API 5LX-70 Spiral Welded Pipe
I just talked to a retired pipe line NDT hand and he said that he has never seen SWP used on gas lines. He also state that they did test some SWP water lines to 1200 psig at one time.
I would call someone like ACIPCO's SWP division and pose your question.

I agree X70-80 DSAW UOE is being used in US and EU, but are you talking specifically about Spiral?
I can only see where X70 Spiral has been used in China and maybe India.

BigInch,
Stelco in Canada produced spiral welded API 5LX-XX in the late 70's and some was installed in gas lines.

RE: API 5LX-70 Spiral Welded Pipe
Yes - I was specifically talking spiral as per operators' statements made in the referenced TWI report.

If X70 is out there, its operating history looks like it will be short (especially in NG years).

RE: API 5LX-70 Spiral Welded Pipe
Thanks for the report info. I've contacted TWI to purchase the report. Hope to hear from them today. I used TWI extensively for materials and failure analysis when employed in the UK during the 90's.
I know of recent natural gas pipelines recently completed in India using HSAW X70 and similarly planned for China.

RE: API 5LX-70 Spiral Welded Pipe
That was the ONLY hit I got. Nothing about a completed report. And completed or not, #1 I'm not interested, #2, I'm not about to buy it for stanweld, whatever it is. #3, Even if it were free, I still think I wouldn't download it.

RE: API 5LX-70 Spiral Welded Pipe
The report is only available to those industries/companies sponsoring the report. One can receive it if one becomes a "sponsor" at a very stiff price. Also please do not misconstrue my query as being in favor of HSAW in natural gas carrying pipelines - only to verify its use at the conditions described.
RE: API 5LX-70 Spiral Welded Pipe
My "NG years" is indicative of a real natural gas company that needs to see ten years of some oil company's experience with something "new" before they'll do it. Almost as long as Pope years.

FYI, the report's sponsors include all the "Big Boys" in the Oil & Gas Industry.

RE: API 5LX-70 Spiral Welded Pipe
If it helps, the TWI report did dispel several HSAW myths.
