[MW:3404] Re: Out of roundness for piping

Yes, it shall not exceed 1.5% of OD as per Clause 10.2.1 of ASME SA
530 (specialised CS and AS tubes)
Also refer Clause 8.2.1 of ASME SA 450 (CS, AS, SS tubes) which will
give you 0.5mm for less than 1inch and 2% of the OD for above 1inch.
Please choose based on your requirement
Thanks
