From petrochemicals and polymers to specialty intermediates and consumer products — reactors, columns, and ASME vessels built with complex metallurgy and code compliance.
Chemical service is where material selection stops being a line item. The same duty in a slightly different stream can call for 316L, duplex, a nickel alloy or titanium, and the difference between them is a tube bundle that lasts twenty years and one that fails in eighteen months.
Harris Thermal fabricates reactors, columns, exchangers and ASME vessels across basic chemicals, specialty intermediates and consumer chemical production — including Lethal Service and Cyclic Service designs per ASME Section VIII, Division 1.
Each alloy defeats a specific corrosion mechanism, and each has an environment that destroys it. We fabricate in the full range and work from the actual service conditions rather than the nominal ones. See our materials and metallurgy capability.
For applications requiring corrosion-resistant wetted surfaces with a structural carbon-steel backing, Harris Thermal can fabricate equipment using customer-specified clad or explosion-bonded materials where appropriate to the design and fabrication requirements.
It is often the economical answer on a heavy-wall vessel where solid alloy would be prohibitive but the process side still has to see the alloy. See our fabrication capability for how that work is carried out.
What each alloy actually defeats, what destroys it, and why a specification that looked correct on paper still puts a tube bundle on the scrap pile in eighteen months.
Tubular and fixed-bed reactors, fluid-bed reactors, jacketed reactors, ASME Section VIII pressure vessels, process and mixing vessels, fractionation and distillation columns, reboilers, overhead condensers, shell-and-tube heat exchangers, replacement exchangers and tube bundles, falling-film and forced-circulation evaporators, scrubbers, cyclones, adsorber vessels, and storage and process tanks. Harris Thermal fabricates equipment for integration into your process; it does not supply the process design or the complete plant.
Carbon steel, stainless steels including 304L and 316L, duplex stainless, AL-6XN, Hastelloy, Inconel, Monel, titanium and other qualified specialty materials. For applications requiring corrosion-resistant wetted surfaces with a structural carbon-steel backing, Harris Thermal can fabricate equipment using customer-specified clad or explosion-bonded materials where appropriate to the design and fabrication requirements.
Yes. Tubular and fixed-bed reactors, fluid-bed reactors and jacketed reactors, and fractionation and distillation columns including column internals, reboilers and overhead condensers. Lethal service and cyclic service designs per ASME Section VIII, Division 1 are supported within qualified project scope, as are heavy-wall shells and large-diameter column sections.
