QualFab Inc. is a world leader in stainless and high nickel alloy radiant tubes for thermal process industries. Radiant tubes manufactured by QualFab are in everyday service in high temperature processes, for both OEM’s and as replacement parts. Our newly purchased tube mill enables QualFab to be especially competitive on certain size tubes and alloys, and to deliver 4.5 and 6 inch tubes in unlimited lengths.

QualFab has fabricated virtually all types of heater tubes, cooling tubes and recuperator bundles for a wide range of applications. We produce tubes using virtually any high temperature alloy, in any form or style. Our skilled craftsmen manufacture tubes in both cast and wrought alloys, and in any tube design including S, O, W, U, P, Double P, and straight tubes. These can be made with or without flanges, bellows, collars, and/or insulation already installed. QualFab produces tubes to your exact specifications, or we can assist you with detailed information to help with alloy selection.

Tube Rebuilds: QualFab will also quote on rebuilding your old tubes as a cost effective alternative to all new radiant heater bundles. With over 20 years’ experience building furnace parts, we have rebuilt many tubes, in order to salvage the valuable alloy content of the portion that has not failed in the existing tubes. Each tube is inspected and tested to ensure the highest quality repair is made.
