Hoses and umbilicals: Outer, inner and contact diameters |
The line type wizard sets up outer and inner diameters and contact diameters for hoses and umbilicals as follows:
The hose inner diameter $I\!D$ and type are input data; the outer diameter $O\!D$ is a function of the inner diameter and hose type \begin{equation} O\!D = \begin{cases} 1.40\, I\!D\ \text{ m} &\text{for high pressure } (90\%-150\%) \\ 1.28\, I\!D\ \text{ m} &\text{for low pressure } \\ 1.34\, I\!D\ \text{ m} &\text{for fold-flat } \end{cases} \end{equation}
The contact diameters are set to '~'.
The outer diameter $O\!D$ is input data; the inner diameter $I\!D$ is set to zero.
The contact diameters are set to '~'.
