The inclusion of instrument winterization and impulse line heating requirements for field-mounted instruments is an integral component of any heat management system. Incorporating the responsibility for the design and engineering of these systems assures that the
heating technology , control & monitoring , and
project controls are consistent with the overall heat-tracing system. |
Decisions as to placement of power connections, power distribution routes and effective use of control and monitoring capacity can lead to significant reduction in installation cost when designed in conjunction with pipe and equipment heat tracing requirements.
The winterization of field-mounted instruments involves a thorough review of design, application, installation, and operations criteria. These include
• Process conditions for associated piping and equipment
• Maintain temperatures
• Maximum exposure temperature
• Power point allocation & distribution
• Transition from process to instrument envelope
• Impulse line configuration
• Instrument enclosure selection
• Control & Monitoring
Deliverables provided for instrument winterization requirements can include
• Instrument installation schedules
• Instrument installation details specific to accommodation of impulse lines and enclosures
• Enclosure details
• Powerpoint assignments |
