HDD Drill Pipe (Integral Type)
Material use OCTG, reliable performance;
Using a unique tool joints twice thicker molding technology;
Transition band is smooth , which can reduce resistance through the mud;
Thread of joints liquid nitrogen treatment, surface hardness higher, thereby pipe life is longer.
Material use OCTG, Pipe end upsetting meet API standard; Thicker tube body quenching and heat treatment, Steel Grade up to G105 or S135;
Welding area using thermo mechanical treatment, welding performance conform to API SPEC 7 Standard.
Winged Reamer (Φ200—Φ1800)
Suitable for hard soil strata and strong-mantle rock formations.
Connection with drill rod: direct connection with drill rod; octagonal connection
Connection with pipeline: with and without swivel
By using the latest optimization design, greatly improving the
service life of the actuator, and minimizing the risk of the construction.
Slider & Shackle
Slider using alloy steel and heat treatment,
the shackle using bow cross pin with nut for high safety.
