The DFI-3000 Series joint is normally utilized in systems where the normal operating temperature exceeds 400 degree F. This design has several features, not
offered in our other joints, which can eliminate many problems often encountered in the field.

As shown, this style joint has the leg of the angle that the fabric is bolted to pointing in towards the breech opening. This is important in that it allows the joint to be installed/removed without having to move any machinery or other ducting. Simply
slide the joint in between existing flanges and bolt up.

Another feature offered is that of being easy to insulate around. The duct insulation
package can be installed right up against the companion flange, minimizing potential
heat loss at expansion joint connection.

Depending on the installation, the cavity of the joint can be easily fitted with an insulation sock should extra protection be required as a thermal barrier or particulate deterent.

The hex nuts within the joint cavity can be welded in position, or we can utilize the Tinnerman style cage nuts which do allow for some field misalignment.
