Structural Composition

The water well drill pipe consists of three main components:

Barrel
Male joint
Female joint

These components feature axial holes and are connected through interference fit from both ends of the rod cylinder. The design includes shaft shoulders on the male and female joints, with the rod cylinder end face welded to the shaft shoulder end face. This innovative connection method provides high torsional strength, making it ideal for shallow well drilling rig applications.

Usage Precautions

Important considerations for optimal performance:

Select the appropriate type and model for your specific construction requirements
Source from reputable, large-scale manufacturers to ensure quality
Conduct thorough formation checks to prevent water blockage
Ensure proper water delivery and accurate design before operation
Be aware that twisting during use may indicate suboptimal materials
