We are constructing two storage spheres as per ASME Sec VIII Div.2 with A516 Gr. 70 & A553 Type 1 material respectively.
For A516 Gr. 70 material sphere (21m Dia, Weld length - 670m) with a single WPS-SMAW having PWHT for pressure part joints of Category A & B. Will Six no. PTC in vertical position qualify ASME Sec VIII Div. 2 requirements?
For A553 Type 1 material sphere (23.8m Dia, Weld length - 120m(1G), 222m(2G), 300m(3G), 300m(4G)) having 4 nos. WPS-SMAW (Client Spec requirement) for pressure part joints of Category A & B.
1G - 1 No.
2G - 2 Nos.
3G - 3 Nos.
4G - 3 Nos.
PTC quantity as per above will qualify ASME Sec VIII Div. 2 requirements?
Kindly share your valuable views.
Thanks in advance.
