Introduction to Water Well Drill Pipe
The water well drill pipe body is made of materials produced by large domestic iron and steel enterprises. Both ends of the pipe body are internally thickened, tempered after friction welding, the drill pipe joint is subject to quenching and tempering heat treatment after rough machining, and the surface is nitrided after finishing, effectively eliminating the failure probability of gluing, breaking, outer diameter cracking, etc., which is more wear-resistant and easy to disassemble.
All water well drill rods are precision imported CNC lathes and customized forming knives for thread processing. All threads are equipped with standard thread gauges, so the quality of the produced drill rods is stable, reliable, and the service life is greatly extended.

The typical components of a drill string include: drill bit, drill collar, drill rod, stabilizer, specialized joint, and square drill rod.
The basic function of a drill string is: (1) to lower the drill bit; (2) Apply drilling pressure; (3) Transmitting power; (4) Transporting drilling fluid; (5) Perform special tasks such as squeezing cement and handling underground accidents.
The series of petroleum drill pipes with API standard E75 to S135 steel grades, outer diameters ranging from 2 3/8 "to 6 5/8", as well as double shoulder joint drill pipes with high torsional performance and BNK C95S drill pipes with special steel grades for sulfur-containing oil wells. Mainly applicable to the construction of deep wells, horizontal wells, and large displacement wells in the process of oil and gas exploration and development.
Main features
Drill pipe is a steel pipe with spiral threads at the tail end, used to connect the surface equipment of the drilling rig with the drilling and grinding equipment or bottom hole device located at the bottom of the drilling rig. The purpose of drill pipe is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit. Drill pipes must be able to withstand enormous internal and external pressure, twisting, bending, and vibration. In the process of oil and gas extraction and refining, drill pipes can be used multiple times.
After multiple processing steps, the light pipe and the original steel pipe are made into drill rods., Through the process of thickening steel pipes, the outer surface of the light pipe is bent inward, and the steel pipe wall is thickened. Next, perform threading and coat with copper that can increase strength. Then non-destructive quality control inspection is carried out, followed by welding of the steel pipe body joints. Subsequently, the tube will undergo welding heat treatment and final welding treatment to eliminate residual welding pressure. Before painting and packaging the finished drill pipe, other tests should be conducted on the steel pipe product, including hardness testing, pressure testing, and non-destructive testing.
