Production Technology: ERW + Cold drawn.

Competive Advantage:

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.

ERW pipe produce progree:

Incoming raw material inspetion,confirm thr raw material is no problem before production.

Cut the steel coil to fit pipe.

ERW the raw marteril to round or other shape of tubes.

Cold drawn the ERW tubes reach a higher tolerance and good mechanical properties.

Test UT ECT flaring tests and  flatten testing.
