Specifies the pipe diameter.

Typical units (depending on your unit system):

  • in

  • mm

  • cm

For ISO 14692 2017:

For all other pipe codes:

1 - Diameter

1 - Diameter

2 - Wt/Sch

2 - Wt/Sch

3 - Sheath Thk

3 - Insul Thk

4 - Liner Thk

4 - Refract Thk

5 - Total wall thickness

Type the nominal diameter and the software converts it to the actual outer diameter necessary for the analysis. If you do not want the conversion:

  • Use a modified UNITS file with the nominal pipe schedules turned off

  • Specify diameters whose values are off slightly from a nominal size (in English units the tolerance on diameter is 0.063 in.)

Available nominal diameters are determined by the active pipe size specification, set by the configuration software. The following are the available nominal diameters.

ISO 14692 2017

Diameter is the outer diameter minus two times Sheath Thk.

ISO-14692 2017 distinguishes between the reinforced wall thickness and the total wall thickness. The reinforced wall thickness does not include the liner (inside) and sheath (outside) the reinforced wall. In CAESAR II, define the reinforced dimension (not including the liner and sheath) for Diameter and Wt/Sch, and separately define Refract Thk, Refract Density, Liner Thk, and Liner Density.
