3 Flat drill pipe
The flat drill pipe is mainly applicable for the needs of Hydro- hammer percussive-rotary drilling (liquid and gas),which is featured by such advantages as high rigidity,good airtightness,
flt external structure,low rotary torsion and less resistance.
Main specifications include50,60 ,73 89,114,which also can be customized according to needs.
4 Geographical drill pipe
Geographical drill pipe is applicable for geographical,hydrographical, coal mine, terrestrial heat engineering
drilling.The main products include 42,50,60 and 63.5.
The major technical indexes of the geographical drill pipes adopt seamless steal pipes are in strict
compliance with international standards.The raw materials of
drill pipes produced by the company are sourced from the five famous steel companies obtaining
the certification of JSO9002 Quality Management System:
China Angang Steel,Baogang steel, henggang steel .The pipe materials for geographical drills
are strictly specified in terms if sizes, forms, weights technical specifications,
test methods,test regulations, package,markings, and quality certificates .All of the seamless
steel pipes adopt the original ex
factory identifications. If it is contracted that goods are delivered in terms of steel grades, the
identifications and quality certificates of the steel pipes are indicated with steel grades.
The steel grades of drill pipes that are currently on the market are DZ40,DZ50,DZ60 and R780 .
5 Nondig drill pipe is a tool applicable for transferring torque and tension of drillers in the process
of directional drilling construction.
Due to the fact that it has to bear torsion,tension, bending ,friction and vibration in the process
of directional construction, the requirements for processing process are very strict.
The raw materials selected by our company are all the alloy structure steels for geographical
usage produced by Baogang Steel.After laboratory tests,the blocks at both ends of a pipe are
thicken directly without welding process ,which are then proceeded to overall thermal processing
and threading, and then are plated with nickel phosphor that can increase the hardness and
airtightness of the the thread surface.Before finished drill pipes are plated and packaged,a
series of tests have to be implemented including hardness, metallurgical structure,physical performances, etc.
