You are planning to float the tender for line pipes so EN 10219 and EN 10210 may be applicable to you. As suggested by Mr.bathula you should go through with this spec and consult the designer for confirmation of the grade and specification.You should also keep in mind the project specific.
EN 10025-2 is for flat and long product which is not applicable in your case since you are going to procure pipes.

Good Morning,
Thanks for your reply. I am confused guys.
Kindly note the following;
·
Below mail from Mr.
Rutvik states that St 52.3 according to edition EN10025-2 converted to S355J0.
·
While a mail from Mr.
Hermen Pieper states two specs. EN 10210 & EN 10219 in which St 52.3 is
called S355J0H or S355J2H.
Friends I am confused. Please can you clarify
the above since I have to float tender for 850MM, 750MM, & 650MM with Dia;
19MM, 25MM, Length 12 Mtrs. Floating and Shore Line Pipes which is a high
value tender.
Your swift response will be appreciated.
Thanks in advance for your cooperation.
With best Regards,

Hi Shiraz,
You are talking about Non alloy structural steel st 52.3 German grade. This
grade was under EN 10025 -93 edition. As per my knowledge 2004 edition is
current edition for EN 10025-2 and in which for st 52.3U( old grade)
converted to S355J0 ( Impact at 0 deg.C) and for st
52.3N ( old grade) converted to S355J2(Impact at -20
deg.C)
Here S denotes structural steel and 355 denotes its yield strength.
I have inspected this material in plate form at various steel plants.
