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
7. Machanical Testing in own labs with Tensile Strength, Yield Strength, Elongation, Hardness, Impact, Mictrostruture etc
8. Packing and Stocking
100% of our steel tubes are dimensionally checked
100% of our steel tubes are visually checked to assure they have a perfect surface condition and no surface defects.
100% eddy current test and ultrosonic test to eliminate longitudinal and transversal defects.
