Product Description

HDD trenchless drill 42mm 50mm 60mm 73mm 89mm 114mm drill rod Friction Welding Drilling pipes

Product Description

Water 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.

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 Technique

	Drill pipe, tool joint raw material The 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 body Pipe 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 process Tool 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 welding Adopts 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 hardbending Arnco, TCS TI, LW600 are available according to customer requirement. the finished hardbending processes with high hardness nd non-cracking character.
Process of internal coating Our internal coating varieties are LPC1000, LPC3000, LPC5000, LPC5000P etc. we can aslo be outsourced processing TK34, DPC, TC2000 series of internal coating.
