DID YOU KNOW? Most tube
deterioration occurs within the
first or last 5%
So why replace the entire tube?
Sleeves, Ferrules or Liners:
.4
Full Length Liners -When
Pitting or corrosion is not
localized
.5
Get More Life From Your Heat Exchanger
• Sleeves – Also called Ferrules, Sacrificial Ferrules, or liners (usually full length)
• New Construction – Often Installed During Initial Fabrication as an Added Layer of Corrosion Resistance
• Field Service – Installed to “Repair” or “Bandage” Tubes in the Field to Extend the Life of an Existing Unit
.6
Sleeves, Ferrules or Liners:
Guards parent tube ends against erosion and/or corrosion.
Restores tubes to service that have been plugged for known perforations
.7
Sleeves, Ferrules or Liners:
Restores tubes to service that have been plugged due to excessive wall thinning.
Bridges cracks or failures in discrete locations
.8
Sleeves, Ferrules or Liners:
Extends HX life Costs less than retubing Faster than retubing Restores plugged tubes Negligible Reduction in Thermal Efficiency Upgrade metallurgy Preventative Measure
.9
Expansion Control = Quality
Strain Control System

Tubular Air Heater Sleeving Repair:
Problem: Cold side corrosion Tube erosion

.14
EXTEND HEAT EXCHANGER LIFE: Consider installing
sleeves as a low cost and faster alternative
to re-tubing!

Individual Tube & Joint Hydro
.19
HydroProof
An Individual Tube or Joint Hydro Test No need to hydro an entire unit
Allows Tests at Pressures up to 2,000psi Utilizes water as test medium More representative than with air or vacuum
.20
Plugging - HydroPlug:
.21
HydroPlug
• Large Surface Seal • Seals Ovular (out-of-round)
Tubes • Can be manufactured using
application specific materials • Unlike Explosive Plugging No Cleanup Great Control over Expansion Safe for Hazardous Environments
