Putting poly through its paces

摘要

Metric or rural poly? Large or small bore pipe? What fittings should I use? How much pressure will be lost to friction? How large a pump will I need? There are many questions that need answering when planning a farm reticulation system. Get it wrong and it can cost you money, but also the loss of precious water, and possibly stock. But get it right and the system will be reliable, long lasting, and cost less to operate. This month's Group Talk tells you how, here's a preview. The introduction of polyethylene (poly) pipe was a giant step forward for convenience and cost of farm reticulation systems.And while poly pipe has now been around for decades, many farmers still remember laying lengths of galvanised pipe and years later dealing with associated corrosion and fouling problems.
