production of API 5L grades

(OP)
Can anybody give me any information about
the production parameters (concerning soaking temperature,
heat treatment, rolling conditions,etc.) and chemical compositions, respectively, to the following
API 5L grades: X60-X80 ?

Thanks for some information!

Best regards,
WoKu

Mn 1.4 max            
P 0.030 max       
S 0.030 max
Nb,V,Ti % or combinations thereof may be furnished by agreement between purchaser and manufacturer.           
Note: The C % and the Mn percentage varies slightly for the welded varieties for the various grades but otherwise similar to the above.

These pipes are normally in the Q&Ted conditions. If you need info on the chemical compositions for the welded pipes let me know.

Thanks and regards

Thank you, Mr Sayee Prasad, for information!

Now I do have another question, concerning API 5L grades:

Is there any difference in produce sour and non-sour API 5L steel grades, especially concerning the hot rolling area?

Best regards,

WoKu

RE: production of API 5L grades


Hi everyone,

I'd like to know about X60-80 microstructure in post fabrication condition and fabrication schedule for welded pipes. I'm working with ultra low carbon steel pipes

RE: production of API 5L grades

Sour and non-sour refers to the fluid flowing in the pipe and not the pipe itself.

For a sour fluid, you need to have tighter requirements than is specificed in API 5L.  For example, control the chemistry and toughness of the pipe.  Suggest you get help from a metalurgest (never could spell).

RE: production of API 5L grades

You should be according with NACE-MR-0175 for material requirements for sour service, the hardness shall be controlated in the material terminated.
