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.
