what is the diif b/w API 5L,/ ASME B36.10M and B36.19M

What is the difference b/w API 5L,/ ASME B36.10M and B36.19M
Why do we use API 5L for offshore & ASME B36.10/19 for onshore.
Please, can anyone explain this to me?

Thanks & regards in advance
Have a Nice day......

1. API 5L: Seamless and Welded Line Pipe.
ASME B36.10M: Welded and Seamless Wrought Steel Pipe
ASME B36.19M: Stainless Steel Pipe
If you'll have a closer look then it is clear that their Material of Construction differs so it is easier to expect that they'll cater to different services.

2. I am not aware of their applications and specialized usage you've stated above.

Regards,

I feel API5L pipes are manufactured as per noms led down by API. concidering upsteem,down streem, slupher conditions so expected to use thes in petrolium industries on and off shower work.
And ASME pipe chemical and allied industrises. dimensionaly there is I think on diffrance.

Thank you.
