[MW:17772] Bend Angle As per ASME Sec. IX

Dear Experts,

We run PQR for the below material:

CENTRALLOY G4852 Micro of Schmidt+Clemens (Cast Pipe) & sample thickness & Dia. is 113.6mm OD x 10.8 mm.

As per  MTC of Base Metals ( CENTRALLOY G4852 Micro - the Elongation Minimum Required is only 8.0%). This material can not be bend @ 180 degree because of low ductility.

Query as below:

The bend test has to be perform as per ASME SEC IX QW-466.1

Please provide the how to calculate the sample thickness for bend specimen (Pls provide example) & minimum Bend Angle to qualify PQR.

Pls provide the code refrence.

 

Thanks & Regards,

Mohd. Azam
