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).
