3D Mandrel Elbow for High-Pressure Pipeline Main Line
It is possible to reduce transportation and construction costs through compactification!
The 3DR elbow is a type of pipe fitting that is commonly used in gas pipelines. It is often manufactured using high-frequency bending, but due to the manufacturing process, an extra length of 1OD (1 outer diameter) is required as a gripping area. However, having this extra length makes it cumbersome during transportation. Additionally, in the case of underground installation, the extra length necessitates deeper excavation during construction, which increases labor costs, including handling. Since many products are used for mainline applications, the impact on costs is considered significant. However, if manufactured using the mandrel method, the absence of extra length improves loading efficiency onto trucks and eliminates the need for deeper excavation during underground installation of the pipeline, making construction easier. Furthermore, the wall thickness of the bend is almost uniform, and the entire elbow undergoes heat treatment, resulting in consistent mechanical properties and high quality, with no discontinuities in wall thickness, making it safe for use in high-pressure conduit mainlines. At Benkan Kiko, we offer 3DR elbows manufactured using the mandrel bending method. We can provide cost-benefit calculations, so please feel free to consult with us.
