[MW:1539] RE: 1538] Min Separation of welds

Dear  Nilesh,

 

No, where it mention distance between two but joints shall be 5t or 300mm in ASME B31.3 .  

You have to consider distance between two joints not less then  minimum HAZ area of both weld.

Many client specification it mention clear information. Bechtel , they are  asking 5t or 50mm.

 

Regards,

Paresh

Dear Mr. Nilesh,

 

Could you pls give the reference paragraph in the ASME B 31.3 which mentions this?

 

I heard it shall be 5t or min 300mm for the size of a pup piece. No where in the ASME B 31.3 I could see it mentioned. Correct me if I'm wrong.

 

Thank you,

 

Regards,

 

 

Sabir
