Inner-grooved Tube Production Process
The conventional production process:
Electrolytic plate → Melting casting → Rolling → Simultaneous drawing (3 continuous drawing) → Pan drawing → Annealing (online annealing) → Internal thread forming → Horizontal rewinding and eddy current inspection → Annealing → Finished product transportation
