Piping Code Cross Referencing and LT Fracture.
Piping Code Cross Referencing and LT Fracture.
(OP)
Does asme B31.3 Table 323.2.2 A have any duristriction on pipeline codes ASME B31.4, B31.8 and PD810-2 (Above water at a B31.3 Interface) ?
Ref PD8010-2
Thought (at this moment) is on using a X65 (for strength) material with a -46 Deg Centigrade and 250 Bar g Design.
Probably be a Thick Cylinder calc but the above from the past (B31.3)reminds me of possible Brittle Fracture and needs be investigated.
Where in PD8010-2 or reference is any of the above covered ?
Really Appreciate some pointers.
Thanks in advance

RE: Piping Code Cross Referencing and LT Fracture.
The material must be selected with the appropriate properties for that service temperature and you will want to be sure to require impact testing at that temperature or less.
Independent events are seldomly independent.

Note, The query is for initial and investigative work.
The Design Temp may get lower which i beleive that something more costly and exotic may be required.
What i am "attempting" is to assess the use a Carbon Steel of a high SMYS (x65) for strength to acheive a min WT that may comply with ASME B31.3 Table 323.2.2 A and therefore use as part of my judgement whilst being PD8010-2 (above water)
compliant. Hopefully i am taking the right track. Again appreciate any pointers in PD8010-2 as a starter.
Incidently sizings could be from 4" to 10"
Hoping that the above is not as clear as mud.
thanks

Just wanting to make sure that everything is correct and procedures "safely followed".
It certainly looks like Fracture Mechanics is going to play the part and will touch base with our Process & Metallurgists
to review my findings when back at work tommorrow
One final question tho ', in your Opinion, Is ASME B31.3 Table A pertinent to our P88010-2 discussion ?
Kind Regards
Pipestan.
