PTC requirement as per ASME Sec VIII Div. 2

[Anish Ramachandran]

Hi All,

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.

Kind Regards,
