The MSABI drilling team have recently been trialing the use of a new line of PVC products fabricated in Tanzania. The PVC pipes are made specially for boreholes and have threaded joints. There is also a factory fabricated filter screen available. The benefits of these new products are high. Previously we had to hot weld our own pipe joints in the field and manufacture our own filter screens using a haxsaw blade. Both these tasks took considerable time and resulted in uneven quality. Hot welding in particular can cause the PVC to become brittle. The following link might be of interest to some - it shows the team installing a threading PVC casing. Click here.
