Hi,
I would use Visio for this, as I have done a few times on assets I have worked on. It is easy to use and also has the benefit that it uses easily available software. That means that if you move on etc, someone else can update the drawing easily without having to get lots of fancy software...
Thanks for that.
I agree about the use of different fluids/temperatures on the test rig meaning that the relieving rate will be different.
However, as I think you agree, the density changes etc should not really affect the lifting pressure of the valve. It will more affect the relieving rate...
Hi,
I am doing a review of our PSV settings and have found the term "cold differential test pressure" on some of the data sheets. When reading definitions of this, I have seen that it is an adjustment to the set pressure of the valve when it is being set, as it is not at process conditions...
