Can I remove this pipe (including bad drawing)

[GhostWorld]

We have a big exhaust pipe going from the kitchen wall (seemingly just inside the wall) all the way under cupboards and oven into the outside wall. We get a lot of damp inside the drawers next to the oven (so much so that we can't use them) so I don't think if the pipe is there for the oven its helping. If its for air flow under the cupboards or into the next room it isn't working either because again the drawers are damp and it doesn't actually go into the next room, just the wall. What bad could happen from me ripping it out? And any suggestions for improving the damp? We're assuming the damp is from the oven. Picture included with water drops to show where damp is. Thanks!

What's it made of? Any chance of a picture.

Yes of course, not a great photo but its one of these

What's it connected to at each end?
Usually that's a vent for a tumble dryer, cooker ventilation fan or other fan

It couldn't vent damp air from those areas shown unless it was connected at the end into those spaces
I would say that as those areas are next to a 'cold' external wall that they probably have damp due to condensation forming (warm kitchen air, condensing on cooler surfaces of the external wall & where the vent goes through the wall)
That or there is a source of damp in that external wall that is coming in - leaking gutter / drain
My initial question after what is the pipe connected to - is if you have kitchen ventilation is it still working properly, does it need cleaning or replacing (they lose power over time) and is it adequately sized in the first place?

Thanks for responding, that's mostly what I thought re not being connected to anything. So the picture was probably misleading but the damp cupboards are next to a wall that leads into another room, so not an external wall. the other side is the external wall which doesn't have damp.
The ventilation for the oven I have no idea about, until I move this pipe anyway! There isn't a vent at the top back of the oven like I've seen in other kitchens, do they sometimes have vents below?

Kitchen ventilation is generally for the hob not the oven - so I would expect either a ventilation hood or a fan in the wall (or in older properties through a window)

However if built in ovens usually need a way for moist air to vent - your particular ovens requirements can usually be found in the manual (if you don't have the manual they are usually available online with a bit of a Google) example here

If that internal wall is cold (less likely than an external wall but can still happen) then condensation can form.

You need to reduce the moisture in the room - cooking produces more than you realise and the best way to do this is with circulating air

If the pipe is just running through this space it isn't ventilating it.

Okay that's all really helpful. I'm going to take out the pipe and then do some investigating in order to get the oven properly ventilated. If I had the money I would probably tear out the cupboards that are damp but I'll have to figure something else out. Thanks so much for your help
