What are PVC Pipes?
PVC means polyvinyl chloride Grekkon Limited carries out irrigation installations within east Africa using different sizes and thicknesses of irrigation grade PVC pipes. All our pipes have a standard length of 6m, with available pipe sizes being; 32mm, 40mm, 50mm, 63mm, 75mm, 90mm and 110mm. Other larger sizes are manufactured on order. In irrigation systems, the larger pipes are used as mains, and the smaller ones as sub mains.
The pipe size is determined by the amount of water required per area. Large farms will use large pipes, while small crop units will use small pipes.
What determines the thickness choice?
- Water pressure. The pressure at which water will flow within. For instance a farmer whose water flow is gravitational will use the lowest gauge, which is PN6. Another grower using a water pump will use a thicker pipe that withstands the pump pressure. The greater the pressure from the water pump, the thicker the pipe is.
- External exposure. Some growers opt to lay pipes on the surface, but most use them while buried underneath the surface. The former will use thicker pipes that withstand the risk of mechanical damage, and prolonged exposure to UV radiation. The latter will use PVC pipes of lower thickness because the pipes have very low exposure to mechanical damage, and are not exposed to the sun’s degrading UV radiation.
PVC pipes have a long usable lifespan that extends to decades. Thicker pipes and buried pipes will last longer. We supply fittings designed for use with PVC pipes to join them together, and with other accessories and material. Every fitting is of the same diameter size as the pipe, but always thicker.
Our irrigation grade PVC pipes are available in our Nairobi, Eldoret and Nyeri stores within Kenya.
