What Carlson Company does

Carlson Company is a Tulsa, Oklahoma-based custom manufacturer of industrial flanges founded in 1958 by Joel and JoAnn Carlson. The company specializes in precision-machined custom flanges for high-pressure, high-temperature applications, serving B2B customers across oil & gas, power generation, water/wastewater, heavy industrial, food/pharmaceutical, and aerospace/defense sectors. Since 2021, Carlson has operated as a portfolio company of Riverbend Industries, a Chicago-based family-owned holding company focused on U.S. manufacturing businesses.

The company manufactures 12 core flange product types (Blind, Slip-On, Studding Outlet, Ring, Long Weld Neck, Weld Neck, Socket Weld, Lap Joint, Threaded, TEMA, Nozzles, and Specialty Flanges) plus complementary machining, drilling, and non-destructive testing services. Its 40,000 square-foot Tulsa facility is equipped with 25-ton overhead cranes, 35-foot bay heights, and CNC horizontal rotary table boring mills capable of producing flanges up to 162 inches in diameter and 50,000 lbs. The company's proprietary Chord Right CNC Indexing Drill Table (U.S. Patent No. 6948720), invented by Jim Carlson in 2002, achieves bolt-hole drilling accuracy to three decimal places. The company holds ISO 9001:2015 certification and complies with AWWA C207-18/C228-19, ASME B16.5/B16.47, API 605/6A, MSS SP-44, NACE 103/175, and EN 1092-1 standards.

Revenue is generated through project-based custom manufacturing contracts, with all pricing determined by quote based on customer specifications including quantity, size, material grade, and complexity. The company operates a direct sales motion with a 24-hour quote turnaround guarantee, serving enterprise and government customers including the New York City Department of Environmental Protection. Marketing relies on a multi-language website (English, Spanish, French, Arabic, Korean, Portuguese) and technical content to drive inbound quote requests, with products shipped directly from the Tulsa facility to customers across the U.S. and globally.

Direct peers

• Bonney Forge Corporation: Bonney Forge manufactures carbon, alloy, and stainless steel forged and cast valves, fittings, and flanges for oil & gas, power, and process industries. It is a direct peer to Carlson because both compete head-to-head in custom industrial flanges and fittings serving refining, petrochemical, and power customers.
• Texas Flange: Texas Flange is a leading U.S. distributor and manufacturer of industrial pipe flanges, including custom and exotic material grades. It directly competes with Carlson in the same custom-flange procurement motion targeting oil & gas, chemical, and industrial buyers.
• Weldbend Corporation: Weldbend manufactures carbon and stainless steel weld fittings and flanges for industrial piping. Like Carlson, it serves the same ASME/ASTM-grade flange market and competes for project-based industrial orders from refineries, chemical plants, and power generators.

Broad incumbents

• Outokumpu: Outokumpu is a global stainless steel producer that also supplies stainless plate and flanges for industrial applications. It is a broad incumbent peer that overlaps with Carlson's stainless and alloy material work but at much larger scale and across many product categories beyond flanges.
• Swagelok Company: Swagelok manufactures fluid system components — fittings, valves, and regulators — for oil & gas, chemical, semiconductor, and power customers. It is a broad incumbent in industrial fluid system components with partial overlap to Carlson's flange and connection solutions.
• Parker Hannifin: Parker Hannifin is a diversified global manufacturer of motion and control technologies, including industrial fittings, valves, and fluid connectors. It competes broadly with Carlson in industrial fluid handling components but operates at vastly greater scale across many product lines.
• Crane Co. Crane Co.'s Engineered Materials segment produces industrial valves, fittings, and fluid handling products serving chemical, energy, and general industrial markets. It is a broad incumbent with overlap to Carlson's process-industry customer base and metal component work.
• Flowserve Corporation: Flowserve is a global manufacturer of pumps, valves, seals, and flow control automation for oil & gas, power, chemical, and water industries. It is a broad incumbent peer with deep overlap to Carlson's refinery, power, and water customer base, though it is much larger and broader in scope.
• Mueller Industries: Mueller Industries manufactures copper, brass, aluminum, and plastic products including industrial fittings, valves, and plumbing supplies. It is a broad incumbent in industrial piping components with partial overlap to Carlson's fittings and connection hardware work across water and industrial customers.

Regional players

• KITZ Corporation: KITZ Corporation is a Japanese manufacturer of industrial valves, fittings, and flanges sold globally. It is a regional-incumbent peer with significant presence in Asia and overlap with Carlson's industrial valve and flange categories, though it is not a primary competitor in the U.S. custom-large-flange niche.
