RE: [MW:10083] Seeking advice in Mechanical Testing of 8" SCH 80 pipe test coupon as per ASME SEC 9

You could do a Macro and Hardness check taking into consideration the future use of the PQR.

Hi,
Yes You are correct.But Instead of Root and face bend test..it can be replaced by 4 Side bend test as per QW451.1 - Note.5.

Thanks & Regards,

Dear  All

My test Coupon is 8" SCH 80 Thk 12.7mm A 106 Gr.b, ( No PWHT & NO
toughness)
As per asme sec9, from QW 451.1
the mechanical test required is Tension test - 2Nos
Face Bend - 2nos
Root bend - 2nos.
& I thought the above test are enough for making PQR & WPS.
am i right?
or else any other test is required r not?


regards
Srinivas
