Whether you need casing to prevent contamination of well zones, prevent unstable upper formations from caving in on your bore hole, a strong upper foundation to continue drilling deeper or a smooth internal bore for installing production equipment. Drilling Supply Equipment can supply casing for any of your drilling needs.

Casing Joints typically come in lengths of 6m, 9m or 12m but we can tailor casing to any length you require. The casing connectors are usually pin x pin (male x male) and connected by short a coupler which is box x box (female x female). We also manufacture casing which is made from one piece with the threads cut directly into casing ends. This style of casing has the pin and box ends cut directly into the tubing and has time saving and cost advantages. We also manufacture casing designed to be re-used. We do this by welding the threaded connectors to the ends.
