Product Name: Friction Welding HDD Drill Pipe for Directional Drilling Tools Model NO.: 73(2 7/8"), 89(3 1/2"), 127(5"), 140(5 1/2") Condition: New Certification: ISO9001: 2000 Type: HDD Size: 73(2 7/8"),89(3 1/2"),127(5"),140(5 1/2") Trademark: CROWN Transport Package: Bundles Origin: China Product Description Friction welding HDD Drill Pipe for directional drilling toolsWe can provide users with the supporting drill pipe of various specifications, thread forms and steel grades for the drilling machine.1. Different from copper plating and parkerizing, the joint surface of our drill pipe for friction welding is specially processed to improve the hardness of the thread and the adhesion of the thread grease. Therefore, the occurrence of thread galling and shackle torque can be reduced, accordingly.2. Since the clamping space is expanded, the trenchless drilling machine positioning and clamping become easier. More importantly, the extended joint can be repaired for the occurrence of worn thread. The drill rod is meticulously designed with special performance for trenchless construction, to reduce the production cost..3. To maintain the stability of the drilling pipe, this range of boring rod comes with double force-bearing shoulders for the application with high torque and wide angel to decentralize the stress.Specification(one piece drilling rod)Dimension of the drilling rodThread formMaterialMinimum bending radius mLength of rod to bend 90° mMax angle(°s)Max % slope % /rod%TorqueKN.mOD of the tubemmThickness of the tubemmLenthmWeightKgOD of the jointsmmBid clamp space of the pin joints and box joins mm50(2")50 6.522057pin joints:110DH50G38603.0"5.22.92.525Box joints:175S3047.14.8"8.3360.3(2 3/8")60.3 7.5225.3 67pin joints:130 DH60G42662.7"4.86337Box joints:180S3351.85.2"9.16.373(2 7/8") 73 834580 pin joints:120 DH23G5891.13.0"5.212458Box joints:180S4570.73.8"5.01373(2 7/8")73 1035887 pin joints:120DH26 G671052.6"4.514.5478Box joints:180S51804.5"7.81683(3 1/4")83 935992 pin joints:130WM80 G73114.72.4"4.116.84.584Box joints:190S65102.14.0"6.91889(3 1/2") 88.9104.5102 104pin joints:150 DH31G80125.73.2"5.622.36130Box joints:230S721134.8"8.324GradeYield StrengthTensile StrengthExtension RateImpact Power Akv JMinMaxMinMin10×10PsiMpaPsiMpaPsiMpa%(-20°C)G105105,000724135,000931115,00079315≥68S135135,000931165,0001138145,000100013≥54
