Product Description

89mm Center Cable Measure While Drilling Drill Pipe Mwd Drill Pipe

Product Description

Features and advantages of MWD directional drill pipe are as follows

(1) Strong tool joints and flexible mid body.
(2) Welded tool joints of specially heat treated steel with very high mechanical resistance.
(3) Optimum concentricity can be achieved through superior friction-welding process and weld inspection
(4) Increased couple outside diameter allows thread have strong strength
(5) Special designed cone trapezoidal thread connection increased thread root area and strength
(6) Increased contact area and concentricity of the thread connection lead to high resistance as to torque & extension and
excellent seal performance
(7) NC lathe manufacturing ensures machining precision of thread

MWD Drill Pipe Scope of application:
While drilling survey drill pipe is generally required to be constructed in a complete coal seam (f ≥ 1) or a stable rock stratum (f ≤ 6); it is mainly used for the construction of gas drainage borehole and water exploration borehole in short horizontal and long-distance underground coal mine, and also used for the construction of directional borehole such as ground and tunnel near horizontal engineering borehole.

MWD Drill Pipe Product features:

1.The drill pipe body is welded by friction welding process, with good mechanical properties and long service life.
2.High thread strength and good adhesion resistance of drill pipe joint.
3.A signal transmission device is designed inside the drill pipe, which can realize the two-way real-time communication between the bottom measurement probe pipe and the explosion-proof computer of the hole, and the transmission efficiency is high.
4.The inner pipe and joint of drill pipe have good sealing performance and high drill pipe stability protection cap shall be worn in time to keep the inside of the drill pipe clean and prevent dirt such as coal dust from entering the polluted steel joint;
