Heat Exchanger Ferrule Inserts

Products

Heat Exchanger Ferrule Inserts

are precision components used to protect and reinforce the tube ends of heat exchangers, boilers, and condensers, especially in areas exposed to high erosion, corrosion, and vibration. These inserts serve as a protective sleeve or buffer between the tube and tube sheet, extending the life of the heat exchanger and maintaining the integrity of the joint.

Metalok ferrule inserts are custom-machined to suit standard and non-standard tube sizes and are available in straight, flared, grooved, and welded designs. Fabricated from high-grade materials such as SS 316/304, Monel, Inconel, Hastelloy, Titanium, and Duplex, they are built to perform in high-pressure, high-temperature, and aggressive chemical environments.

Erosion & Corrosion Resistance
Shields tube inlet from flow-induced wear and chemical attack.
Wide Material Options
Available in SS, Monel, Inconel, Hastelloy, Titanium, Duplex, and more.
Custom Machined Designs
Manufactured to match specific tube OD, wall thickness, and insertion depth.
Straight & Flared End Types
Supports both standard and expanded tube insert installations.
Grooved & Welded Variants
– Available with internal grooves or weld-on types for high-integrity seals.

Prolongs Tube Life
Prevents premature tube thinning and cracking at the inlet.
Reduces Downtime & Maintenance
Minimizes repair frequency, saving on shutdown time and cost.
Enhances Performance
Maintains tube integrity and heat transfer efficiency.
Minimizes Tube Replacement
Allows isolated protection rather than full tube bundle changeout.
Improves System Safety
Prevents leaks, tube failures, and potential contamination between fluids.
