PVC pipe / round electrical conduit (Longton ST3)

Hi, does anyone have a small section of pvc plumbing pipe/ or round electrical conduit please? The type you would use for hot/cold domestic water/ or round electrical conduit pipe. It’s for a project I have in mind so I only need a small offcut , say a couple of foot, I’m guessing 20mm / 22mm diameter (or similar) will work for my project. Thanks in advance
