Dear all,

 

Greetings.

 

Please inform me PTC(Production test coupon requirement) for below details--

 

Construction Code :  ASME SEC VIII DIV 1

 

Shell Material :   SA 387 GR 12 CL 2,  65 & 70 Thk.

 

MDMT :  0 Deg Celcius

 

Impact test is required as per  ASME SEC VIII DIV 1.

 

The Heat number for shell material for 3 vessels is not same.

 

 

3 vessels are required to be fabricated as per the above requirement for single  client. The vessels are going to to be erected at one location only. 

 

The thichkness of shell material for 1 vessel is 65 Thk and for other 2 vessels is 70 Thk. Diameter and Length of the vessel is different. Only MDMT and material is same.

 

Please inform me whether seprate  PTC( production test coupon)  is required for each  vessel  OR 1 PTC attached with longseam/Circ. Seam of only 1 vessel  will also represent other 2 vessels also.

 

Whether 2 PTC ( 1 for longseam &  1 for circumferential seam for 1 vessel)  is enough for all three vessels OR total of 6 PTC are required for 3 vessels.

 

Please give code reference.

 

Thanks in advance for your valuable suggestions.

 

Regards
