A 333 Gr.6 toughness test

[dia shukr]

Hi friends

I have pipe A333 Gr,6 with design minimum temperature (-10C).Will I need to do a toughness test??As you know, depending on table A-1 in ASME B31.3 the minimum temperature is (-50C).

Thanks every one

Dear vishwas,

The problem is not clear. But I feel that you are having a pipe that are eligible to be used up to -50 degree C as per standard and you want to use those in design temp of -10 degree C. 

Kindly see the original linkable certificates.Preferably type 3.2 certification- EN 10204.If the accepted impact test results of given lot no.  show temperature meets your requirement, you may use. However is always safe to test a sample and witness the same.

no, replace the pipe.

No issue because it is come with impact tested to -45 Deg and your temp is -10 Deg you just tell your client give them code reference as this grade can use upto -45Deg so you can use it no issue in that.

Thanks & Regards

Mr. Rohit Barge

hi 

If SA333 LTA materials it already qualified in -46 Dec just you want to conform  impact test it passed. then -10 Deg no issues ....

and same if you want to save materials cost use SA 106 Gr. B  also  you want to test impact temperature -10 Deg.....

regards
