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.
The parameters and performance are as follows:
1: Technical parameters: The high degree of fin 0-16mm (or outside diameter of fin φ 38.1-φ77m); Pitch of fins 2.3-12mm; Length of finning tube 0.5~ 14m.
2: Single metal rolling finning tube: Pure aluminum 1060 or aluminum alloy 6063.
3: Double metal rolling finning tube: Tube-based protection from the outer layer of aluminum tubes, corrosion-resistant; Tube-based can be made from carbon steel pipe, in addition to, stainless steel tube and copper tube can also be used, as well as titanium alloy tube.
Package: The aluminum finned tubes are well packed in steel frame and polywood.
