Control Flow

What Control Flow does

Control Flow, Inc. is a privately held U.S. industrial manufacturer founded in 1975 and headquartered in Houston, Texas, that designs and manufactures pressure control, motion compensation, tensioner, and pipe handling equipment for the oil and gas industry, plus specialty products for the U.S. Military and approved foreign governments. The company operates through five product groups: CFI Flocon (pressure control, including API 6A-licensed wellhead equipment, gate/pipeline/ball valves, subsea valves, chokes, manifolds, BOPs, Christmas trees, and the trademarked Breech Block Connector™), CFI Mo-Comp (offshore motion compensation, including the Drill String Compensator, Crown Block Compensator™, UMCCA™, and production riser tensioner systems), CFI WesTech (pipe lay, cable lay, and pipe handling systems, including the "E" Series Pipe Tension Systems and abandonment/recovery winches), a Government Sales Operation (UNREP tensioners, submarine rescue/launch/recovery equipment, vessel steering gear), and International Operations. The company's product IP was assembled through three strategic acquisitions — WesTech HMD (1997), ABB Vetco motion compensation and tensioner lines (1999), and Retsco (2008) — and it owns multiple trademarked product lines including the registered RIMAC® Riser Anti-Recoil Control System.

The company makes money primarily through engineered-to-order OEM equipment sales (quote-based, no public price list, with Texas-law arbitration and net-30 payment terms), recurring aftermarket revenue from its 5-Year Maintenance and Certificate Program (API 6A Sect. 53 for manifolds and API 16AR for BOPs, including OEM "rebranding" of qualifying third-party equipment), government specialty product sales, and equipment rental via its Mexico-based CFM-Tools Rental operation. Distribution is hybrid: direct enterprise field sales from Houston, TX and Moore, OK, a wholly-owned Mexico subsidiary established in 2005, and a worldwide network of sales agents, distributors, and Authorized Repair Facilities. Certifications include API 6A (2024-2029 Certificates of Authorization), ASME, ISO 9001, NACE MR-01-75 sour service compliance, U.S. Government SAM vendor registration, and FCPA/conflict minerals/anti-slavery compliance documentation. Headcount is in the 101-250 range; revenue is not publicly disclosed.
