API 2 3/8 Water Well Drill Pipe DTH Drill Rod Tube
1. Description
Drill pipes that are used in applications such as DTH/ DTHR/ DR basically comprise of a steel pipe with a pin at one end and a box on the other. The job of the drill pipe is to transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools.
Usually the threads are standard API connections, like 2 3/8" API REG thread, 3 1/2" API REG thread or API IF thread, etc. According to customers request, from 1000mm to 6000mm length of pipe are available.

3.The main function of water well drill pipe
1. Transmission of power: The torque and power of the drilling rig are transmitted to the drill bit, allowing the drill bit to rotate and cut the formation, achieving drilling operations.
2. Transport medium: As a channel, it transports flushing fluid (such as water, mud, etc.) from the ground to the drill bit, playing a role in cooling the drill bit, cleaning the drill cuttings, lubricating the drill hole wall, and carrying the cuttings back to the ground, ensuring the smooth progress of drilling work.
3. Extending the drill string: With the increase of drilling depth, by continuously connecting new drill rods, the length of the drill string is extended, allowing the drill bit to reach deeper formations.
Performance characteristics of water well drill pipe
1. Reduce water pressure loss: The inner diameter of the tool joint upsetting end is basically the same as the inner diameter of the drill pipe body, and the pressure loss can be reduced by 20% -50%. The design of the perforated drill pipe also helps to reduce water pressure loss, improve drilling efficiency and speed.
2. Corrosion and fatigue resistance: Rinsing the internal structure reduces corrosion and improves fatigue resistance, making continuous sampling and wire rope drilling possible and adaptable to complex working conditions.
3. High strength and stability: Made with high-quality materials and exquisite craftsmanship, it has the characteristics of high bending strength, large rotational torque, and smooth operation, and can withstand high-intensity workloads, extending its service life
