Good Quality Friction Welding DTH drill rod 76mm 89mm 102mm Api Dth Drill Pipes

D Miningwell equips all rock drilling equipment with high-quality friction welded drill rods. The threads, rod bodies and welded joints of the drill pipes have been rigorously processed.
Thread: We can produce all threads that comply with API international standards, and guarantee precision processing. The thread material is 35CrMo, and it has undergone high-quality heat treatment and nitriding treatment to ensure the hardness and service life of the thread.
Rod body: We can supply drill rods with diameters of 42mm-203mm, and the maximum length can be made up to 12 meters. We choose DZ40, R780, G105, S135 and other rod materials according to the needs of different customers and the use scenarios of drill rods, and the wall thickness can be 4.5mm-12mm.
Welding joint: Each drill pipe has undergone a pier thickening process, and the maximum inner/outer pier thickness can be up to 22mm, which increases the friction welding area and ensures the stability of the welding joint.

What preparations must be done if friction welded drill pipe is used for drilling water wells

Surface water must be explored for friction-welded drill pipes to drill deep water wells, and geological engineering professionals can also be invited to do this work. Looking for low places in the high altitude According to the topographic conditions, go to the valleys or low-lying places to find water. If the drilling is in the mountainous area, the surface water generally accumulates in the valley.
One thing to pay attention to when drilling deep wells by machine is that for effective drilling, it is not necessary to drill deep water wells and shallow water wells casually, but must first pass a stable investigation process. The use of an appropriate water pump should be carried out according to the specific situation, because the water pump to be used should be based on local conditions and its main parameters of various overall goals. The number of water level lines and the situation of the pump working on the spot should also be checked for the dynamic, static data water level and water flow of the deep well. Well water flow liaison. It is the use of drilling operation methods, which should be carried out by appropriate deep well drilling, because the difference in natural environment may have different technical requirements.
Friction-welded drill pipes are used to find water in rock formations with uneven cracks, and the unevenness of rock cracks should be used. Look for areas where fractures are growing, such as around dikes. Dies are rocks that have intruded into surrounding formations as a result of volcanic activity or other geological formations. Because of the intrusion of the dike, the drilling smashes the surrounding rock formations, creating more aggregated fractures to store surface water.
