Why pvc casing borehole

Our PVC-U Casings and screen pipes are manufactured with selected PVC compounds to provide absolute non-corrosive pipes with excellent mechanical properties. The casing and screens are threaded flush internally and externally to two standards:. Designed by Duncan-Fyfe Consulting. All Rights Reserved. It also works as a cover for the water transfer pipes, safety rope, electrical wires as well as the pump itself.

The casing also helps with ensuring that surface water and shallow ground water which might be polluted do not mix with the ground water. They are made in sections which are screwed together to form longer lengths. Each casing has a male and female threading to ensure it is able to be connected to the next pipe section. Most often the male threads are covered with a thread protector before assembly to prevent any damage on the threads.

How deep should the Borehole Casing Pipe be? Since the casing is mainly used for protection, its depth should be able to provide the necessary protection. As a rule of thumb, the casing should - at minimum be 6m deep. It should also be at least 2m below the pump. This protects the pump from the wall collapse whilst also preventing mud and sand from entering into the pump. How to choose a borehole pipe casing What should my Casing diameter be?

The diameter of the borehole casing should be enough to fit the pump and clearance enough to cater for easy installation and maintenance. Corrosion Resistant: Borehole pumps are particularly susceptible to both rust and corrosion since they are made up of metallic parts, and then throw a little water and electricity into the mixture, and in such cases, rust should be less of a concern than galvanic corrosion, which can reduce an appliance to a husk of its structure in no time at all.

PVC piping is made from a versatile material, is completely corrosive resistant, making it ideal for borehole pumps which provide the exact kind of environment where galvanic corrosion thrives. Durable and Long Lasting: PVC piping ages well, which is why it is commonly found in homes and buildings all over the world.

Borehole pumps operate constantly and often under gruelling circumstances that may induce weathering and wear-and-tear over time. PVC is remarkably resistant to these types of damage, and as such is ideal for protective borehole casing pipes.

Simple to Install: PVC is a fairly simple material to work with, and requires few if any, specialized tools to manipulate and fit it. This makes PVC casing fairly simple to install and maintain when the need arises. Popular Posts. September 10, April 26, October 30, September 14, Borehole Systems. Contact form.
