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.ModelWall Thickness(mm)Effective Length(mm)Connection

FlatFeatures: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.Hunan Hippo Drilling
