a. Liquid nitriding treatment for the joints allows for a higher penetrating layer comparing with traditional phosphating process
b. The joint demonstrates uniform distribution of hardness and hardened layer. It is highly durable
c. Split waterway design is employed for the inner reamer body so that mud won't enter the chamber
d. Cutter of the reamer is made from high-alloy material, featuring high impact resistance and wear resistance
e. The reamer is designed with spiral rotate type spray system. Users can change different diameters of nozzle according to different construction needs
f. A wear resistant area is set to extend the reamer's life
HDD drilling is a construction technique to build, repair and replace underground pipeline without excavation utilizing pipeline detection technique. It uses drill rig to produce holes and receives the signal sent by drill bit to realize an effective control upon the movement path of holes. Its working process can be divided into 3 steps: hole drilling, hole expanding, and dragging pipeline back.
Applications
a. Horizontal drilling in various complex geological conditions
b. Drill tools with different specifications for pipeline with different weight and diameter
c. Drill tools with different specifications for drill rigs of different push force and dragging force
d. For different specifications of drill rigs and drill tools
e. Various rod specifications are available for different geological conditions
