Does anyone have any photo's or a sketch on a hyrdo test fixture for tube bundles?
I am looking at leak testing the expanded tubes in the tube sheets
I am new to this area and do not want to reinvent the wheel.
Er, why not flange onto the exchanger's inlet and outlet pipework connections? One would test any joints in the exchanger structure at the same time.
Do make sure the test is witnessed by the Engineer/Surveyor for the company that is supplying burst indemnity insurance cover for the equipment, or it will need to be repeated in that individual's presence.
That is our plan, to connect to each side.
For this particular heat exchanger however, the stationary and the floating tube sheets are not tied together by tie rods.
What would a free body diagram look like with test plates attached?
16 inch dia at 225 psi, 300 degree F
Why? - Is a mechanical re-design on the cards?
This is a replacement heat exchanger or was the question directed towards the test?
Well, if it's a one-for-one replacement, just give it a squeeze and see what happens.
You'll need an inspector to sign of on it. The inspector doesn't have a suggestion? Or if the inspector doesn't know, you should probably find a new inspector.
You could contact Vestas aircoil, they design and manufacture charge air coolers for large diesel engines.
