olof91 Posted March 20, 2011 Share Posted March 20, 2011 Hi,I'm going to buy a 5m HDPE pipe from my local pipe-supplier. They have two different inner diameter sizes: 79,2mm and 73,6mm ID. Which one will be most suitable for 3" ball shells? Link to comment Share on other sites More sharing options...
Algenco Posted March 20, 2011 Share Posted March 20, 2011 I would go with the 79.6mm, 3.1" Link to comment Share on other sites More sharing options...

pillyg Posted March 20, 2011 Share Posted March 20, 2011 I think the bigger one is better because if the shell doesn't fit, you can just add another layer to make it fit. It would be easier than if the pipe was to small and you had to remove a layer from the shell. Link to comment Share on other sites More sharing options...
Bonny Posted March 21, 2011 Share Posted March 21, 2011 As noted above, go with the larger size. 3" is ~76mm. You also want to have some clearance around the shell. Link to comment Share on other sites More sharing options...
