The Tube Mill Quality Control:
1. Incoming Raw Material Inspection
2. Raw Material Segregation to avoid steel grade mix-up
3. Heating and Hammering End for Cold Drawing
4. Cold Drawing or Cold Rolling, On line inspection
5. Heat Treatment:+SR, +A, +N
6. Straightening/Cutting to specified length/Finished Measuring
Inspection
7. Quality Testing in own lab with Tensile Strength, Yield
Strength, Elongation, Hardness, Straightness, etc.
8. Packing and Stocking.100% Eddy Current Testing.
100% Size Tolerance Checking.
100% Tube surface checking to avoid surface defects.
