Does this air compressor look like it is worth trying to save?

[Hohn]

Yes, I'd test it. Put a gauge on there and pressurize it to at least twice the working pressure. You could also use a pressure washer if you know how to adapt it.

No to the first and no to the second.

Do NOT pressurize to double the WP and definitely do not use a pressure washer.

Pressure washer pumps 2,000 psi and up. That is too much for any air tank except scuba tanks, use a grease gun filled with water instead of grease.

No one said it was pumped up that high, hence the gauge install. Dial back the unloader on the pressure washer to reduce the pressure.

It sounds like this tank needs to be kept in a cage, a strong cage.

Make sure the tank isn't full of water.

Took the drain valve out and about 4 drops of water came out. Probed the hole to make sure it wasn’t plugged

W.P = working pressure 200 psi
TP = temp 450 degrees
SH= shell thickness of body .166?
HD= head thickness on top/bottom of tank .133?
RD= radiographic testing 2:1
Tank date 1980
DIV 1= hazardous area classification

I understand most of this but what does the RD and DIV 1 mean?

DIV 1 means the requirements of the ASME code for pressure vessels below 3000 psi.

I understand most of this but what does the RD and DIV 1 mean?

As said above, the DIV 1 means the tank was built per ASME Section VIII, Division 1 Code.

If AI is to be believed:

In radiographic testing (RT) for air tanks, "RD 2:1" describes the image sharpness requirements for weld inspections. It stands for a geometric unsharpness limit of 0.020 inches and refers to the ratio of the source-to-object distance to the object-to-film distance. Air tanks hold high-pressure gas. Weak or thin weld points can cause the tank to burst. The 2:1 geometric ratio ensures that X-rays easily identify dangerous internal weld flaws, like cracks and gas pockets, without producing a blurry, unreadable image.

This is a Campbell Hausfeld TF000021P pump.

Unscrew the pressure relief valve on the cylinder head on the low pressure cylinder. Put in a gauge and run the pump. If it goes to about 30-40 psi while running and does not follow tank pressure above that, the valve plate is good. If it is jerky and goes back to zero between crank rotations, the LP valves are leaking. If it follow tank pressure past 40psi or so, the HP valves are leaking. If the valves are good and it isn't knocking, it is a pretty good compressor pump for a home user. I'm not sure if you can still find parts for it. Master tool repair might still have something.
