HDD Trenchless Drill 42mm 50mm 60mm 73mm 89mm 114mm Drill Rod Friction Welding Drilling Pipes¹

Product Description HDD trenchless drill 42mm 50mm 60mm 73mm 89mm 114mm drill rod Friction Welding Drilling pipesProduct DescriptionWater well drill pipe is a kind of drilling tool that uses alloy steel pipe to thicken the upsetting at both ends, and connect with tool joints by friction welding. The quality of the drill pipe mainly depends on the selection of materials and the strength of the joint thread. Good materials are not easy to bend or break due to fatigue. The dense tissue after the end upsetting can effectively improve its mechanical properties and strength of the connection.Features:1. The rod material of the drill pipe is made of STM-R780 material, which has stable and reliable performance. The end is heated by intermediate frequency, hydraulically upset, and heat treated, which effectively eliminates the internal stress of pre-processing.2. The tool joints are made of 42CrMoA material, which is quenched and tempered after rough machining, and subjected to surface nitriding treatment after finishing.3. The threads are all cut and formed by CNC lathe forming inserts, with precise coordination and strong interchangeability. Detailed PhotosModelWall Thickness(mm)Effective Length(mm)Connection TypeJoints Length(mm)MarksΦ644.81500/2000/30002-3/8 REG170/170 Φ7641500/2000/30002-3/8 REG190/190 Φ7651500/2000/30002-3/8 REG190/190 Φ766.51500/2000/30002-3/8 REG190/190 Φ895.51000/1500/20003000/4000/50002-3/8 REG200/200 Φ896.51000/1500/20003000/4000/50002-3/8 REG200/200 Φ896.51000/1500/20003000/4000/5000NC26280/200Double Wrench FlatΦ1028.51000/1500/20003000/4000/4500NC31230/230 Φ1028.51000/1500/20003000/4000/4500NC31300/300Double Wrench FlatΦ1148.51500/2000/30004000/4500/5000NC35230/230 Φ1148.51500/2000/30004000/4500/5000NC35300/300Double Wrench FlatΦ12791500/2000/30004000/5000NC38240/240 Φ12791500/2000/30004000/5000NC38320/320Double Wrench Flat Product Process Authorized by ISO 9001, NS-1 and Russia GOST RTN . it is able to process drilling tools according to standard DS-1 under a full system of production design and quality control.. our drill pipes have been tested by the third party, such as China national petroleum pipe research insititue and Russia petroleum pipe quality control center, the quality is stable and reliable.Manufacturing TechniqueDrill pipe, tool joint raw materialThe material adopts high-performance alloy steel according to USA API standard and strictly checked by chemical content, metallographic structure, geometric dimension, NDT tests etc to ensure the stable quality of the products.Process of drill pipe bodyPipe end is upsetted by USD National Oil Well equipment with 1250tons weight. heating treatment is process by oven-type automatic furnace, then straigtened by 6 rollers straigtening machine, whole courese hardness test and ultrasonic inspection.Tool joint processTool joint is processd by 1500T gaint pressure forging machine to ensure the quality of joint for high compactness, cleanness, hard wear resistance, homogenization of excellent mechanical performance.process of friction weldingAdopts USA MTI equipment for friction welding, automatic computer control, heat treatment, grinding, magnetic particle inspection to guarantee high quality of the finish products.Process of hardbendingArnco, TCS TI, LW600 are available according to customer requirement. the finished hardbending processes with high hardness nd non-cracking character.Process of internal coatingOur internal coating varieties are LPC1000, LPC3000, LPC5000, LPC5000P etc. we can aslo be outsourced processing TK34, DPC, TC2000 series of internal coating. Packaging & Shipping Company ProfileHunan Hengan Weiye Metal Products Co., LTD is subordinate to Hengan Weiye Steel Pipe Co., LTD.
