What UNITED CASING does
United Casing, Inc. is a privately held oilfield services company founded in 1974 and headquartered in The Woodlands, Texas. The company trades and distributes Oil Country Tubular Goods (OCTG) — primarily casing, tubing, and line pipe — and operates API 5CT and API 7-2 certified threading facilities that prepare pipe to customer and project specifications. The company also offers the proprietary ACR-T16 internal coating for corrosion protection and supplies premium connections, moving beyond pure commodity resale into value-added processing.
The company's business model is industrial trading combined with thread-and-coat services. Revenue is generated by purchasing OCTG, holding an average inventory of approximately 5,000 tons across three US stocking locations (Midland, Houston, and Corpus Christi), and reselling — often with threading, coating, or premium-connection finishing — to oil and gas operators. Go-to-market is project-driven, selling to a customer base of more than 100 firms worldwide, including major international oil companies and national oil companies. The company is family-managed, with members of the Vatne family involved in commercial roles, and employs 101–250 people.
United Casing is a focused, mid-sized OCTG specialist with a 50-year operating history. Its product mix (commodity casing/tubing, threaded pipe, ACR-T16 internal coating, line pipe, premium connections) and its geographic footprint (Permian Basin, Gulf Coast, South Texas) position it as a regional platform serving both domestic shale and international export channels. No AI/ML, software, or data product is part of the offering.
