Thrust blocking prevents main line from moving when the pressure load is applied. In efect, the thrust block transfers the load from the pipe to a wider load bearing surface. Thrust blocks are required where fittings are used to change the direction (i.e., at all ties, elbows, wyes, caps, valves, hydrants and reducers) of the…
The connecting link between the pump and the irrigation system is the mainline. Mainline material is normally steel, aluminium with couplers, cement asbestos or plastic. Sizes can range from 5″ to 48″ plus. Generally with center Pivot, a water source at the pivot is most convenient. When water is unavailable at the pivot, a mainline…
The Pivot industry markets almost exclusively steel center-pivots. The principal method of protecting against corrosive decay from rusting include: painting, epoxy coatings, use of alloys (so called weathering steels) and galvanizing.
