Re: [MW:13144] Is it downcommers comes under saperate piping

Hi,

No need seperate MDR/MPDR. you can include in the Shop MDR and note that the joint will be weld at site. after weld you can  update your existing welding record done at site and signed off by AI if applicable.(Only the first joint of the vessel/equipment to the another Pipe or other joint is within the limits of ASME)

 

Thanks & Regards,
