O' Brien Heated Sample Line Best Practices

Heated Line Best Practices Heated Sample Line Best Practices HEATED SAMPLE LINE Read all Instructions provided prior to Installation Measure twice and cut the correct end once Heated Sample Line Best Practices Installation Best Practices: Cut from the correct End – Spool will be marked with these stickers affixed. Probe end or Power end can be spooled depending on direction of install. Probe End Power End Temperature Sensor Temperature Sensor Location should be located in ambient conditions Heated Sample Line Best Practices Installation Best Practices: Field Insertion of RTD Options Recommended Option # 1: Insertion of RTD sensor through a SensorTube™ or spare tube in heated core. Option # 2:Field insertion of RTD. RTD sensor should allow for sensing in ambient conditions Heated Sample Line Best Practices Installation Best Practices: Proper Supports × Bad : Possible Damage to entire construction: Jacket, Insulation ✓ Maximum Support Centers Vertical Runs - 15 feet (5 meters) Horizontal Runs - 6 feet (2 meters) Unsupported Horizontal Runs - 6 feet (2 meters) maximum.* Support centers should be placed so bundle does not sag between supports. This distance will vary by bundle configuration. Good: Use Kellum grip or Closed Mesh Support Grip and proper rigging and supports to protect bundle/umbilical Heated Sample Line Best Practices Installation Best Practices: Proper Sealing ✓ Good: Entry Fitting has had proper sealant and heat shrink applied × Bad: Bulkhead fitting has not properly installed. Sealant and Heat shrink is needed Heated Sample Line Best Practices ALWAYS KEEP LINE SEALED DURING ENTIRE INSTALLATION PROCESS. Moisture will damage insulation causing failure. Never leave insulation exposed Spools are shipped from O’Brien with cap. Always replace the cap. Heated Sample Line Best Practices Installation Best Practices: Proper Supports × ✓ × ✓ Stainless Cable Ties are not recommended as may cut into jacket Heated Sample Line Best Practices BAND-IT has a 316 SS coated tie Crossing Nylon Wide Cable Ties can provide the additional support ✓ Heated Sample Line Best Practices Installation Best Practices: Spacing ✓ Bundles require ½” gap between them to give up their heat and should not be clamped tight as it causes hot spots in the bundle. × Heated Sample Line Best Practices Installation Best Practices Proper Slope ✓ × Measure Twice Cut Once Heated Sample Line Best Practices Installation Best Practices: Bend Radius ( Typical is 8” – 12”) ✓ × Heated Sample Line Best Practices Why heat trace from point A to Point B?
