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.
