| Mechanical Property | Index |
|---|---|
| Yield Strength | ≥235MPa |
| Tensile Strength | ≥370MPa |
| Elongation | ≥15% |
| Bend Test | For pipes with an outer diameter ≤22, the bend radius is 6 times the outer diameter of the steel pipe, and the bend angle is 90°. For DN15 – DN50, the bend radius is also 6 times the outer diameter, and the bend angle is 90°. After the test, there should be no visible cracks |
| Flattening Test | When the weld of the sample is at a 90° angle to the force – applying direction, there should be no cracks in the weld when pressed to 2/3 of the outer diameter (D), and no cracks in the part outside the weld when pressed to 1/3 of D |
| Hydraulic Test | The hydraulic test pressure is calculated according to P = 282t/D, and the maximum test pressure does not exceed 5MPa |
