I'm trying to verify the burst disk capacity of an existing system. The over pressure scenario is a pump continuing to pressurize a tubing system with a valve closed downstream. I'm using the resistance flow method because the tubing between the pump and the burst disk is 1/4" but the burst...
I am performing a code analysis on a shop made "vessel". It is basically a piece of 3" Sch 10 SS pipe with two 5" x 7" rectangular flat heads welded on each end. Two 1/4" AN910 couplings are attached to each head for nozzles.
The head joint configuration matches UW-13.2(e-1). My question is...
At my government facility, we are required to recertify pressure vessels every 20 years. Recertification involves verifying the vessel meets all the current ASME and local pressure vessel requirements. As part of that recertification effort, the ASME B&PV Code calcs are redone. When the...
I am working on ASME B&PV Section VIII, Div. 1 calcs for an existing ASME "U" stamped vessel at my facility. The problem is that while the vessel nozzles meet the minimum thickness requirements per UG-27, they do not meet the thickness requirements of UG-45. The nozzles range from 1" to 3"...
