Material and Design Advantages
API 5L Grade B carbon steel offers good weldability, strength, and toughness, making it suitable for a wide range of pipeline applications.
The 5D and 10D radius bends minimize flow resistance and reduce stress concentration compared with short-radius elbows.
For corrosion protection, selected bends are finished with , providing excellent resistance to moisture, soil, and chemical exposure, while black paint is applied for standard protection during transportation and installation.
