Precess And Features
- ERW Pipe Precess: Uncoiling → Leveling → Shearing and Welding → Looping and Storage → Forming → High-Frequency Welding → Deburring → Sizing → Cooling → Straightening → Flying Saw Cutting → Inspection and Packaging
- Features of erw black steel pipe:
- High production efficiency, low cost, and excellent value for money
- High dimensional accuracy, uniform outer diameter, and excellent straightness
- Robust weld seams and stable mechanical properties
- Suitable for galvanizing, painting, and anti-corrosion treatments, making it ideal for outdoor environments
- Easy to cut, drill, bend, and weld; offers excellent machinability
- omprehensive range of specifications, covering everything from small to large diameters
- Bend Test
- For pipe NPS 2 [DN 50] or smaller: Cold bend at 90° around a cylindrical mandrel 12 times the outside diameter of the pipe without cracking any part and without cracking the welds.
- The double-extra-strong pipe over NPS 1/4 [DN 32] not be subjected to the bend test.
- Flattening Test
- The flattening test applies to welded steel pipes that are larger than NPS 2 [DN 50] and have a wall thickness less than extra-strong (XS).
Seamless steel pipes do not require a flattening test.
