Petrochemical & Refining

Refine your process with total corrosion protection

Significantly extend the service life of key petrochemical and refining components with our tungsten carbide thermal spray coatings or our super-durable Thermal Sprayed Aluminum (TSA) Corrosion Protection System.

Our tungsten carbide coatings, which are applied via the high-velocity oxy fuel (HVOF) process, protect against abrasion, galling, erosion and corrosion for a wide range of components—including piston rods, plungers, pump sleeves, rotor shafts, mechanical seals and valve stems.

Featuring self-healing edges, bare surface tolerances of 4-6% and resistance to mechanical damage, our TSA system is ideally suited for even your highest-temperature applications. And because of its minimum need for maintenance, it is extremely effective in combating one of the most critical issues you face—corrosion under insulation.

At Praxair Surface Technologies, we are the premier applicator of the TSA Corrosion Protection System. With our specialized arc spray process, we can deliver superior bonding and high productivity so you can forget about corrosion and focus on your business.
