NICKEL-BRAZED TUBE TO MANIFOLD JOINTS

Tubes are joined to manifolds with a nickel alloy using a vacuum brazing furnace.

Unlike rolled tube-tubesheet joints, our specialty brazing process creates a permanent bond between the tube and manifold. The nickel alloy braze compound forms a joint stronger than both steel base metals.

As opposed to “yellow” brazing alloys, our nickel based braze compound is compatible with sour gas and other corrosive applications.

Our state of the art vacuum brazing furnace also allows us to stress relief anneal the rigid nickel brazed joint, as well as heat treat per ASME.

KEY FEATURES OF OUR DESIGN

• Our advanced turbulator design used in our oil coolers and radiators is superior to conventional designs. It greatly increases efficiency while resisting fouling and plugging. It is offered in both carbon steel and stainless steel construction.

• Requires minimal maintenance.

• Brazed tube-header joints mean tubes never need to be re-rolled.

• Access plugs are not required. This greatly reduces the the total number of joints and potential failure points and streamlines the manufacturing process.

• Removable cooler sections.

• Quick and easy replacement/repair of damaged coolers.

• Eliminates downtime for costly tube inspection, removal, cleaning and re-rolling.

• Allows for easy access to fan and drive components from the front without the need to disassemble the entire back end of the cooler.
