PWHT Heating and Cooling rates PNo 6 Group 4
(OP)
Hi,
Need some guidance on PWHT heating and cooling rates. An new to ASME and still finding my feet, the standards are laid out a little different from the Australian Standards I am used to.
Thanks

SA 240 S41500 13Cr–4.5Ni–Mo (plate version of CA 6NM)
SA 352 CA6NM 13Cr–4Ni
SA 479 414 12.5Cr–2Ni–Si
Use of the above materials would be required by code case because they are not listed as pressure retaining materials. PWHT would need to be established using the material specification or by code case use.

Any suggestions on cooling rate (JWHIT - "air cooled")?
Thanks

do you have ASME BPVC SECTION II , PART A-2 2013 available to you , you would be able to look here in SA-487-CA6NM .

Thanks guys, I thought I was on the right track, good to hear it from others. This forum is a wealth of knowledge and experience.

The PQR should be qualified to ASME B&PV Code, Section IX, which requires bend and tensile testing, and not RT. Unless, you are talking about welder performance qualification.
Second, I would qualify the WPS using both PWHT's as part of the PQR.

I am qualifying my procedure to Section IX, RT is being performed as a precaution before mechanical testing is carried out. The test plates have cost me big $$$ (special pour from the foundry). If there has been a operator issue I can re-weld using the same plates.

My test has passed RT. Heat treatment plan is sorted. Thanks
FYI NDT is also a requirement for Australian Standards (AS) before you can procedure to mechanical testing. AS is a mixture of ASME and BS.
