Fabsco

What Fabsco does

Fabsco is a privately held U.S. industrial manufacturer organized as two Oklahoma LLCs—Fabsco Shell and Tube, LLC and Fabsco Fin-Air, LLC—that designs and builds custom heat transfer equipment for industrial process customers. Founded in 1970 and headquartered on a 20-acre campus in Sapulpa, Oklahoma (a 12-acre main facility plus an 8-acre satellite for raw materials and structural welding), the company produces TEMA-type shell and tube heat exchangers at scales up to 144-inch shell diameter, 250,000 lbs, and 70-foot tube lengths, and API 661 air-cooled heat exchangers up to 65-foot tube length, 140,000 lbs, and 22-foot width. In-house capabilities include a machine shop, 100% tube finning, structural welding, and an integrated AutoCAD-based design and drafting system that supports 3D modeling for customer integration.

Revenue is generated primarily through custom equipment sales on a quote-based, multi-year project cadence, with pricing unavailable publicly. A second revenue stream consists of replacement parts and field services—commissioning, re-tubes, re-rates, troubleshooting, preventative maintenance, and 24/7 emergency support—covering both Fabsco equipment and competitor units. Sales are executed entirely through a network of six regional independent representative firms spanning the U.S. and Canada (Files and Associates, Kempker Associates, Thermal Products, Southgate Process Equipment, Power Systems Specialists, and Bay Industrial); there is no direct e-commerce or self-serve channel. Technical credibility rests on ASME S and U code stamps, NBBI R/S/U authorizations, TEMA and HTRI memberships, and API 661 alignment, which together form the gating credentials for code-stamped pressure-vessel work in refineries, petrochemical plants, and similar industrial facilities.
