public class ProcessDesignStandard extends DesignStandard
Process design standard providing design margins and safety factors for process equipment sizing.

This class provides standardized design margins for:

  • Design pressure (margin above maximum operating pressure)
  • Design temperature (margin above maximum operating temperature)
  • Flow capacity (safety factor for design flow rates)
  • Duty margins (safety factor for heat transfer equipment)

Values are loaded from the TechnicalRequirements_Process database table based on equipment type and company-specific standards.
