Stainless Steel Oil Hdd Drill Pipe For Horizontal Directional Drilling Machine
Drill pipes that are used in applications such as DTH/ DTHR/ DR basically comprise of a steel pipe with a pin at one end and a box on the other. The job of the drill pipe is to transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools.
According to different application, different diameters of drill tubes are needed, basically, smaller DTH hammers need smaller DTH drill tubes, vice versa. Usually we are offering 50mm, 60mm, 76mm, 89mm, 95mm, 102mm, 114mm, 127mm, 140mm .
Drill rods for HDD machine. High strength, high tenacity, high elasticity. Dia from 42mm to 140mm. Length from 0.5m to 9.6m. Steel grade: E75/R780,G105,S135 We can make the drill rods for Vermeer,Case,Ditch Witch, Drillto, Gudeng, Xugong HDD machines, such as D16X20, D24X40, D50X100, D75, D80, D100, D130, JT1720, JT2720, JT2720 March I, JT4020, JT7020, API NC23-NC50, etc.

Drill pipe quality control:
a) Before order to be confirmed, the raw material of pipe body and tool joint should be booked from famous big steel enterprises in China
b) Raw material’s size, quantity, length, mechanical property are checked by our QC staff and factory own laboratory
c) Every drill pipe has nondestructive inspection , cleaned and thread oil before packing.
d) Before delivery clients could send one QC or point the third party to check the quality such SGS, BV or others.
Drill pipe usage notes:
1. New drill pipe should be pasted thread oil before connection.
2. Make up and break at least 3 times before drilling.
3. Hard bending and plastic coating can be processed according to clients’ special requirement.
