DIv 1 : Hydro pressure is Exceed 3000 psi, Can U stamp Possible ?

 

[TGS4]

Why would it not be?

 

[jte]

Indeed. Why would it not be possible?

 

[ArpEng]

It's Exceed the limit of Div 1. so its Possible ??

 

[XL83NL]

What limit are you actually talking about? The 'limit' defined in VIII-1 U-1(d) is for pressure design (conditions), which is something else than the hydrotest, which is a test condition.
If you read U-1(d), you'll notice the 20 MPa (3000 psi) is not a 'hard' limit, but a limit where the Code addresses that the common DBF rules are usually not well defined for these conditions, and extra provisions are required.

 

[ArpEng]

What type of extra provisions are required ??

 

[XL83NL]

None you have to do when you do a hydro @ 3000 psi for a Div 1 vessel.
