Specifies a jacketed piping code to indicate whether the piping commodity is required for the core piping, the jacketed piping, or the jumper tubing. Valid entries are listed in the AllCodeLists.xls workbook on the JacketedPipingBasis sheet in the Codelist Number column. This option allows the piping designer to select fittings from the same piping materials class on the basis of whether the core, the jacket, or the jumper is being modeled. The software does not use this data in this version.
