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.
