The Component Insulation Exclusion Rule node (the ComponentInsulationExclusion sheet in the InsulationData.xls workbook) helps to eliminate false clashes involving piping and instrument components. This rule identifies conditions under which a component, such as an instrument indicator, is not insulated even though it exists on an insulated line. Additionally, valves, flanges, and unions are typically not insulated for personnel protection. This rule does not have any effect on runs for which Insulation Purpose is set to Undefined.

The components that are not to be insulated are determined on the basis of the piping commodity type; the first size range; the second size range; the Multi-Size Option; the Heat Tracing Requirement (heat traced or not), the Insulation Requirement (hot or cold insulation), and the Insulation Temperature.

The software uses the following convention to determine the temperature to use as the basis of the rule:

  • If the piping designer has specified the pipeline insulation temperature, then that insulation temperature is used.

  • If the pipeline insulation temperature is undefined, then the heat tracing medium temperature for jacketed piping (the operating temperature of the jacket fluid) is used.

  • Otherwise, if the heat tracing medium temperature is undefined, or non-jacketed piping is being used, the temperature is determined on the basis of these case conditions:

  • If hot insulation applies, the maximum temperature of the applicable (maximum) case conditions is used.

  • If cold insulation applies, the minimum temperature of the applicable (minimum) case conditions is used.

First Size From

Type the smallest size in the first size range for this rule.

First Size To

Type the largest size in the first size range for this rule.

First Size Units

Type the units of measurement for the first size values. For example, type in or mm.

Heat Tracing Medium

Select the heat-tracing medium to which the rule applies. Valid codelist numbers are specified on the HeatTracingMedium sheet in the AllCodeLists.xls workbook in the Codelist Number column.

Heat Tracing Type

Select the heat-tracing type to which the rule applies.

Heat Tracing Requirement

Select the heat-tracing requirement to which the rule applies.

Insulation Purpose

Select the insulation purpose to which the rule applies. Valid codelist numbers are specified on the InsulationPurpose sheet in the AllCodeLists.xls workbook in the Codelist Number column.

Insulation Type

Select the insulation type to which the rule applies.

Insulation Requirement

Select the insulation requirement to which the rule applies.

Insulation Temperature From

Specify the lowest temperature in the temperature range to which the rule applies.

Insulation Temperature To

Specify the highest temperature in the temperature range to which the rule applies.

Multi-Size Option

Type a string to represent an optional piping commodity selection for multi-sized fittings when the first size and second size are inadequate.

For example, if two additional sizes (2" and 1") are required in addition to a first size of 6" and a second size of 4", the string that would represent the sizes would be 6x4x2x1. The software interprets the string to determine the second size and the number of sizes in addition to the first size and second size. Do not include a unit of measure in the string. The unit of measure for the first size, defined in the First Size Units column, is used.

Piping Commodity Type

Specify the commodity type/codelist number for which you are defining a rule. Valid commodity types codelist numbers are specified on the PipingCommodityType sheet in the AllCodeLists.xls workbook in the Codelist Number column.

Piping Commodity Sub Class

Select the piping commodity sub class.

Piping Commodity Class

Select the piping commodity class.

Second Size From

Type the smallest size in the second size range for this rule.

Second Size To

Type the largest size in the second size range for this rule.

Second Size Units

Type the units of measurement for the second size values. For example, type in or mm.
