Leaders in Gas Conditioning Technology

Since 1962, QB Johnson Manufacturing has engineered and fabricated custom natural gas conditioning and processing equipment for domestic and international projects. Our work ranges from wellhead TEG dehydration units, amine treating systems, filter separators, and line heaters to thermal oxidizers, heat exchangers, molecular sieve packages, and modular gas plants.

Every project starts with the application: gas composition, flow rate, pressure, temperature, outlet specifications, plot space, site conditions, and applicable code requirements. Equipment is engineered, fabricated, inspected, documented, and tested through our Oklahoma City facilities before shipment.

QB Johnson supports operators, engineers, EPC firms, and procurement teams with practical equipment design, in-house fabrication, quality documentation, startup support, and spare parts support after the unit is in service.
