QUALIFICATION THICKNESS LIMITS ASME IX

[1973Patrick]

Hi,

What is de T range if:

SMAW - Plate 15 mm - V-groove - P6 - PWHT and Impact tested in PQR

Table QW-451.1 ASME IX said: Over 3/8 (10), but less than 3/4 (19) = 2T for T for base metal.

Someone told me that T = 1.1 x T because Impact test and PWHT performed during the PQR

Is that so and where is this described in te ASME IX?

Thnx!
Patrick
