API Steel Application Center
 |
 |
|
Aiming to take its API steel
business to the next level, POSCO opened the API Steel
Application Center in May 2005 to develop future technologies
through a multidisciplinary R&D program encompassing
metallurgy, pipeforming, welding, and corrosion evaluation.
The center consists of three labs: the Pipeforming Lab,
the Corrosion Evaluation Lab, and the Welding Lab.
|
1. The Pipeforming Lab
|
Equipped with the world’s first UOE
simulator—an integrated forming press that handles
bending, closing, and expansion—the Pipeforming
Lab determines the physical property correlation between
API steel and the formed pipe to help pipemakers achieve
optimal manufacturing results.
The lab is also equipped with state-of-the-art “crack-tip
opening displacement”, “drop-weight tear”,
and “wide-plate tensile” testers to facilitate
pipe research and performance evaluation.
