Production process
Raw material – annealing for material of 45#, 27SiMn, 25Mn – Acid cleaning – parkerizing & Saponifying – cold drawn – leveling – saw off bad section – stress relieving – leveling –honing or skiving – inspection – oiled plated - packing
Quality control
1. We only buy raw material from famous tube factory, and Checking raw material quality before production.
2. We check the tube ID tolerance, OD tolerance and surface after cold drawn one by one.
3. We inspect the honed tube inside tolerance and surface again one by one after honing or skiving.
