Water well drill rod production process
The drill rods produced by our company are all processed using materials produced by well-known large steel enterprises in China, such as Baosteel BAOSTEEL, Angang Steel, Xining Special Steel XINING SPECIAL Steel, and Henggang. The heat treatment of the materials is carried out using an integrated non oxidizing furnace, and all thread processing is carried out using professional CNC machining. All threads are equipped with thread gauges that meet international standards, and the rod body and tube ends are thickened internally. After friction welding, tempering treatment is carried out, so the quality of the processed drill rods is stable and reliable, and the service life is greatly extended. The drilling rod of the water well is welded with a friction welding machine, which has high strength, good elasticity, is not easy to bend, and is firmly and reliably connected to ensure quality.

Water well drill rod · structural composition
The water well drill pipe is composed of a barrel, a male joint, and a female joint. The rod cylinder, male joint, and female joint have axial holes, and the rear end of the male joint and the front end of the female joint are inserted into the axial holes of the rod cylinder through interference fit from both ends of the rod cylinder; There are shaft shoulders on the male and female joints of the water well drilling rod, and the end face of the rod cylinder is welded to the shaft shoulder end face of the male and female joints. The water well drill rod is a new type of rod that is connected to the male and female joints through radial interference fit and welding from the axial end face. Therefore, the water well drill rod has high torsional strength and can meet the needs of shallow wells for drilling rigs.
Water well drill rod · Precautions for use
Because there are different types and models of drilling rods for water wells, it is necessary to choose the most suitable type and model for use during construction in order to achieve the best results. When choosing water well drill rods, it is necessary to go to a reputable and large-scale manufacturer to ensure quality. In order to prevent water blockage during use, it is necessary to check the formation, ensure timely water delivery, and ensure accurate design before using this equipment. In addition, if the water well drill pipe is twisted during use, it is more likely due to the manufacturer's use of suboptimal materials in the production of this equipment. Therefore, in order to achieve good results, customers need to pay more attention when purchasing to ensure its effectiveness.
