Dunno if this is any good to you I have some plastic pipe sorry it's not 40mm this is 30mm outside diameter and 22mm inside diameter I have two lengths 1 is approx 4.6 metres and the other is approx. 7 metres long they can be joined together as I have found a bit of pipe that fits. I know it's not what you were looking for but if it's any good to you just let me know. I live in Eastham.I'll put a picture up if I can find out how to do it.
Thank you so much but I probably didn't describe what I needed very well. I need fairly rigid pipe and it has to be 40mm. I've got loads of connectors for 40mm pipe which can be used to create any 'lego' type structures. I've got lots of the connectors but not much pipe. I've made a fruit cage over the strawberries but need more pipe for the other fruit beds. The below picture shows exactly what I need. Thanks for looking, Vicky
