So the simple thing I'm after is for pipe bombs to collide with Tanks, the same way molotovs and vomit jars do, however I can't seem to find what actually disables the collision.

I've tried using SDKHook_ShouldCollide on both the tanks and the pipe bombs but neither seem to do anything.

You can check this plugin https://forums.alliedmods.net/showthread.php?t=327838 to have some tips
Don't know if that is what you want.

From what I can see, that doesn't seem to work either, to be more specific it's the pipe bomb projectile entity that I want to collide, I may have had it configured wrong but that plugin also has the same issue where pipe bombs just go straight through.

Have you tried hooking the pipebomb projectile entity, sdkhook touch? I did something similar to create sticky bombs in a private plugin, i managed to make them stick to surfaces that way, but clients touch are a little trickier, i had mixed results, try hooking the pipebomb entity or the tank itself, string check for the pipebomb projectile in touch hook, or vice versa for the tank, printtochat or printtoserver the results to see if its triggered.

another hackish way to do it would be to track the tank and pipebomb projectiles origins, get the tanks mins and max and do some calculating there to see if its within the tank bounds. I personally wouldnt use that method except as a last resort.
