We manufactures Wireline Drill Rods, from WLA to WLP, Parallel Threaded Drill Rods, DCDMA Sizes AW-HW, and Metric sizes 42mm to 90mm, Tapered Threaded Drill Rods, DCDMA Sizes AWY to NWY, AWJ, BWJ and S75 Drill Rods.

High-quality drill rods are usually on the Reverse-Circulation drill rig and they are made with high-grade alloy steel with a seamless drip and a high tensile factor. Most high-quality drill rods have a wear resistant drill pipe and this ensures that it has some longevity with an added durability. They are shock resistant have a resistance to abrasion, a high grade of machinability, and have been handle in high temperatures so the varying degrees would not affect its performance.

Factors such as drill rods have also contributed towards the mining industry. Their presence has allowed professionals to implement a thorough approach towards activities such as drilling and extracting. Presence of drill rods allow people to dig inside the ground and search for minerals. The composition of these drilling rods is such that they can easily withstand the hard rocks present below the soil and passes through them with a force whereby the mining activity can take place.

We manufactures Metric Casings, Flush-Jointed Casings, Flush-Coupled Casings. Casing thread is 4 threads per inch. Casing length is generally supplied with length 3.0m, 1.5m & 0.75m. Casing tubes are used in the walls of oil and gas wells as the structural retainer for protecting subsurface formations, offer protection of wellbore from collapsing.

Casing tubes are geological mining tools and designed to increase productivity while excavating minerals and precious metals. Tubes can be made from carbon and alloyed steel for durability. The dimensions of the tubes vary depending on the depth the miner is digging.
