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 and Cold Rolling, on line inspection

5. Heat Treatment, +A, +SRA, +LC, +N, Q+T

6. Straightening-Cutting to specified length-Finished Measuring Inspection


100% Eddy Current Testing.
100% Size Tolerance Checking.
100% Tube surface checking to avoid surface defects.
