Select API standard steel such as J55, N80, or P110
Steel grade identification through eddy current testing
Control the cutting length error of the pipe blank within ± 0.5mm
2. Rough machining stage
Use a coupling cutting machine to complete the fixed length cutting of the pipe blank
Band saw machining outer circular reference surface
CNC lathe rough inner and outer diameters, with reserved 0.3-0.5mm precision machining allowance
3. Thread processing
Using a 1:16 taper CNC lathe to machine API standard threads
Hook type thread design (bearing angle -3 °) to prevent loosening
The thread diameter tolerance is controlled within ± 0.002 inches
4. Heat treatment and surface treatment
Perform quenching and tempering heat treatment on steel grades above N80
Phosphating treatment forms an anti-corrosion layer
Copper plating process (current density 3-5 A/dm ²)
5. Quality inspection
Three coordinate measurement of thread geometric parameters
Wet magnetic particle inspection for detecting surface defects
100% full inspection of thread fit for the pass stop gauge
6. Finished product processing
Coupling painting and rust prevention treatment
