Long Industries

What Long Industries does

Long Industries Inc. is a privately held heavy-industrial fabricator headquartered in Buffalo, Texas, operating three manufacturing facilities in Buffalo, Teague, and Carlsbad totaling over 300,000 sq. ft. Founded in 1992, the company designs, fabricates, and field-erects aboveground storage tanks and pressure vessels for the oil and gas value chain — from upstream production and gathering, through midstream pipelines, to downstream refining and terminals — and increasingly for chemical, petrochemical, power, pharmaceutical, food and beverage, alternative fuels, water/wastewater, and government customers.

The core technical offering is anchored by a deep code-stamp portfolio: API 650 monogram (welding the company to a small national group of certified tank builders), API 12F monogram for shop-fabricated tanks, ASME Section VIII Division 1 and Division 2 (U and U2 stamps), ASME R and S stamps for repair and fabrication, UL 142, UL 2085, ULC S655, and National Board Authorization. Manufacturing covers API 12F, 620, and 650 tanks, gun barrel tanks, stainless and UL 142 tanks, fiberglass tanks via a supply partnership, and a broad ASME pressure vessel line including separators (vertical and horizontal, 2-phase and 3-phase), heater treaters, free water knockouts, vapor recovery towers, reactors, heat exchangers, distillation columns, scrubbers, surge drums, and high-pressure contactors. Engineering is performed in-house using Compress, AutoCAD Mechanical, and AutoCAD Inventor, with NACE-certified coating and lining services applied in-house or in the field.

Revenue is generated through custom project-based sales, stock inventory sales of pre-fabricated tanks and vessels for immediate delivery, recurring repair and maintenance work under API-653 and ASME R-stamp authority, turnkey field construction (foundations through tie-in piping), and an in-house logistics and trucking division. The go-to-market is direct enterprise field sales — quoting per project, managed by dedicated project managers — with no channel partners, distributors, or marketplace exposure. All revenue is domestic, with operating geographies concentrated in Texas and pricing quoted per specification across a single-currency, project-based billing cadence.
