DHD Standard Seamless Steel Drill Tube Weighted Drilling Pipe Tool
DHD Standard seamless Steel Drill Tube Weighted Drilling Pipe Tool High Torque 3M
Heat treatment technology for the drill rod
the drill pipe adopts natual gas walking furnace for heat treatment, the heat treatment of hardening and high
temperature is conducted in closed type of space.temperature in furnace is controlled by multi point thermocouple.
furnace temperature uniformity of quenching holding section is 20C. furnace temperature uniformity of high temperturre
tempering area is 10C.patented quenching process with accuracy can guarantee pipe body and upsetting area
fully austenitizing simultaneously but not bring coarsening of austenite grain size.after drill pipes finish quenching
and come out from furnace,immediately even cooling them by inner spray and oter shower.cooling speed is faster
than critical cooling rate of drill pipe material.
steel drilling tooling double shoulder desing for Pin and box connection:
*add a secondary shoulder on the pin and box thread connection end
*main shoulder with function of sealing an bearing more torque
*secondary shoulder with function of partial torgue and overland protection
*secondary shoulder has function of complementary sealing the whole drill pipe sealing ability is imported
drill pipe tooling Quality control :
DHDT drilling rod hasone automatic non destructive test line with 16 channels ultrasonic and thickness measurement
800 pieces of dirll pipes can be tested one day, test range of outer diameter varies from42mm to 168mm.make
sure that threr is defect in the drill pipe body
