Haihao Group recently completed the production and shipment of a batch of DIN 2448 ST35.8 seamless steel pipes for a long-standing customer in Malaysia. These pipes were manufactured with strict adherence to dimensional tolerances and surface treatment requirements to meet the needs of high-temperature and high-pressure industrial applications.
DIN 2448 ST35.8 seamless steel pipes with black coating and capped ends
Project Details
The order includes three different pipe sizes, each cut to a fixed length of 6 meters, with black paint coating and plastic end caps to ensure surface protection during handling and shipment:
| Outside Diameter (mm) | Wall Thickness (mm) | Outside Diameter (inch) | Length | Surface Finish |
|---|---|---|---|---|
| 168.3 | 11.0 | 6″ | 6 meters | Black painted |
| 114.3 | 6.3 | 4″ | 6 meters | Black painted |
| 88.9 | 5.6 | 3″ | 6 meters | Black painted |
All seamless steel pipes were manufactured in accordance with the DIN 2448 standard, using ST35.8 carbon steel-a material known for its good weldability, uniform structure, and resistance to high-temperature environments. These properties make it suitable for applications such as boilers, pressure vessels, and heat exchanger systems.
Highlights of the Shipment
- Standard: DIN 2448
- Material Grade: ST35.8
- Production Method: Hot-rolled seamless
- Length: Fixed 6 meters
- Ends: Plain ends with protective plastic caps
- Surface: Black lacquer coating to prevent rust
Each pipe underwent rigorous quality inspection before dispatch, including dimensional accuracy checks, hydrostatic testing, and visual surface inspection. The seamless steel pipes were bundled securely and labeled with full traceability to ensure a smooth customs clearance and end-use traceability for the customer.
