Name the pipe/fitting type: Water return inside water in

[Dan'llfixit]

Hi,

I am trying to find the name/type of pipe in which the one water pipe is contained within another but with opposite flow. I have attached a childlike 2D drawing for clarification.

Any help/advice appreciated.

You have sketched a "concentric tube, counterflow heat exchanger".

Whether that is actually its role in your application depends on details that you have not shared with us. You probably won't be able to pick one up at Screwfix. Try talking to companies specialising in hydraulic/pneumatic sytems, e.g.

HYDRAULIC AND PNEUMATIC SERVICES - Systems Group UK LTD

Don't expect them to be cheap.
