UDS requirement for ASME Sec VIII Div-2 Vessels

[Agrawal Sunil (Mumbai -Stequ)]

I need your advice. We are procuring a Pressure Vessel from our Vendor having Sec VIII Div-2 code. Div-2 ask for UDS (User Design Specification). We have reviewed the content of UDS (in cl 2.2.2 of ASME VIII Div-2) but all these information are already provided by us in our Mechanical datasheet/ Material Requisition and other Engineering specification sent to Vendor. In this case, do we need to prepare another separate document (called as UDS, repeating the inputs) or all documents already provided to them may be called as UDS.

 

Best Regards,

Dear Sunil,

When you want a vessel manufactured and Code stamped as per ASME Div 2, you have the following additional documents.

1. UDS ( User Design Specification)

2. Manufacturer's Design Report.

As a user, your company need to issue User Desgn Specification ( UDS) certified as required by 2.2.2. of ASME Sec VIII Div 2, to the manufacturer.

A sample UDS is attached for your reference.

You can prepare one like the attached and issue to manufacturer.

Please note that this document need to be certified an RPE or a certified Engineer as required by Annex 2.A.2 of Code.

I hope this clarifies your doubt.

Hi,

If the equipment is designed as per Div.2 but we do not require it to be code-stamped. Does making UDS a mandatory affair.
