Water Well Drill Pipe C12FFFA4

Short Description:

Product Detail

Product Tags

Water well drill pipe is an improved product of down-the-hole drill pipe. Both ends have fine buckle male heads, which are used with lock joints. When sticking, snapping, and outer diameter expansion and cracking occur, there is no need to replace the drill pipe as a whole, and the head can effectively save drilling. Cost We can provide OEM or ODM services, and we can also customize drill rods according to your required material, length, wall thickness, and thread.
Our self-developed perforated drill pipe improves drilling efficiency and drilling speed by reducing water pressure loss. The inner diameter of the upsetting end of the tool joint is basically the same as the inner diameter of the drill pipe body, and the pressure loss is reduced by 20%-50%. Flushing the internal structure reduces corrosion and improves fatigue resistance, enabling continuous sampling and wire rope drilling.

Product Connector

connection type: Fine thread
The fine buckle can strengthen the tightness of the connection with the lock joint.

Product Usage

Application fields: used in geological survey, core drilling, water well drilling, mine blasting, geothermal well drilling, coal and non-ferrous metal mining engineering and other drilling projects

Product Advantage

The rod body material is Shanghai Baosteel STM-R780 (42MnMo7), which is not easy to be bent or broken by fatigue, and has stable and reliable performance. The rod end is heated by medium frequency, hydraulically upset and thickened, and then buried tempered for 12 hours to ensure the compactness of the drill rod and improve the mechanical performance. All use precision imported CNC lathes and custom shaped knives for thread processing, which precisely ensures the tightness of the connection with the lock joint.
