API 5L and pipes with longitudinal seams
(OP)
Is it right that pipes with longitudinal seams are NOT included in the API 5L Standard? If it's so, which standard is applicable?
Thanks

RE: API 5L and pipes with longitudinal seams
API 5L includes both seamless and welded pipe.

RE: API 5L and pipes with longitudinal seams
The case is that someone told me, that longitudinal welded pipes are EXCLUDED from API 5L, so we put explicitly in the contract conditions to use helicoidal welded pipes.
Now my question is, if that is true. Because if not we could also permit longitudinal welded pipes as long as the fabricant satisfy the criteria of the API standard.
RE: API 5L and pipes with longitudinal seams
I amazed that people write contract specifications based on hearsay rather than procuring the standard.
API-5L is available for about $209 USD in print or PDF format.

RE: API 5L and pipes with longitudinal seams
If you're looking for a standard for potable water distribution (i.e., human drinking water), then I'm not sure why you would want to go with one from the American Petroleum Institute (API). They don't normally deal in potable water. There are some potable water International Standards Organization (ISO) standards, but mainly for plastic piping (as far as I could find in a quick search).
I would recommend that you ask your client to provide you information on the applicable Mexican standards and then either compare them to your European standard or use the ISO standard.

RE: API 5L and pipes with longitudinal seams
Indeed I was surprised and so I began my investigation about other applicable standards like AWWA 200C "Steel water pipe" to see if we can change the required conditions (espacially conditions about coating but also material, fittings and joints) to reduce costs.
RE: API 5L and pipes with longitudinal seams
-AWWA C200
-API 5L
-EN 10224
my conclusion is, that AWWA C200 (and EN 10224) is just applicable for steels up to grade 55, when API 5L is also applicable for X60 - X80 and in my case I need up to PN70, X65 --> API 5L
Please respond if you disagree.
NozzleTwister: At least now I have all these standards
