Alloy Steel HDD Drilling Tools For Horizontal Directional Drilling Rig
Description:
Non-dig integral forged drill pipes are used to transmit drill torque and pullback force during the directional drilling project. The manufacturing process of the pipes is very strict because the pipes must bear twist, pullback, friction and vibration in the course of drilling.
The raw material used in Double Horse is all the alloy steel produced by BAOSTEEL. The green tubes are upset in both ends seamlessly without welding after laboratory examination. Then, the forged pipes are sent for heat treatment and threading. Finally, the pipes are plated with nickel-phosphor to enhance the hardness and tightness of the threads surface.
The finished pipes will be sent to pass a series of tests such as tests for hardness, metallurgical structure, physical property, ect. before they are covered with paint.
We can provide all kinds of Drilling pipes, Sonde housing with drill bits, Fluted reamer, Barrel reamer, Cutting reamer, Swivel, Sub saver, Male and female slider, Shackle, Case slip, Mud stirring system and so on. We can provide these products with good quality by advanced technology.
Quality Inspection:
Advanced crack detection center with real time imaging system and one lab for spectral analysis, hardness, tesile strength, yield and impact tests.
