Pipe Spool Fabrication & Replacement Services

Fairtex provides pipe spool fabrication, replacement, and flowline upgrade services for oil & gas production, petrochemical, offshore, and floating production facilities. Our capability supports both surface and buried pipeline systems across operational and brownfield environments.

We execute spool replacement projects through a multidisciplinary delivery model involving engineering verification, prefabrication, welding, installation, testing, and commissioning. Our teams support shutdown-driven interventions, integrity restoration programs, and facility upgrades while ensuring compliance with project specifications and operational safety requirements.

Typical applications: crude flowlines, flare lines, gas lift systems, chemical injection lines, hydraulic piping, utility air lines, produced water systems
