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)
