B31.8 for t greater than 6.02mm   max offset 3.2mm

         for t less than or equal to 6.02mm  max o'set

         is 1.6mm

B31.3   max offset is 1.6mm

API 5L t less than or equal to 12.7mm max offset is

           1.6mm

If you are referring to ASME B31.3, refer para 328.4.2 and 328.4.3, generally it is permitted as stated in the applicable WPS. However in case of HP piping it is 1.5mm (1/16"), that's why most of the WPS states as 1.5 or 1.6mm as permitted misalignment.

Dear Vivek, I think you will never get proper answer untill your working code.

Is there any code that provides any limitation or guidance . Regards, Vivek
