(773) 277-1600 | Oil and gas infrastructure operates in some of the most corrosive environments on earth — sour gas with H₂S, high-chloride brines, high-pressure CO₂, and aggressive hydrocarbon chemistries that attack metal surfaces relentlessly. From subsea completion equipment operating at 10,000 psi in seawater, to refinery process vessels handling hydrogen sulfide at elevated temperatures, to LNG cryogenic transfer systems — every component must perform flawlessly over its entire service life.
Able Electropolishing works with manufacturers of components across upstream exploration and production, midstream pipeline and processing, and downstream refinery and petrochemical applications. Our electropolishing process removes micro-burrs, free iron, and surface stress — creating a dense Cr₂O₃ passive layer that dramatically resists H₂S stress corrosion cracking, chloride pitting, and CO₂ corrosion in sour service environments.
Compared to passivation alone, electropolishing is 30 times more effective for improving corrosion resistance — critical when a single component failure can trigger a well blowout, pipeline rupture, or refinery incident.
Send us your oil and gas component sample to evaluate finish and dimensional changes. We process samples at no charge and turn around in 2–3 days. Request your free electropolishing sample and see the difference before committing to production quantities.
Hydrogen sulfide attacks metal surfaces at the atomic level — promoting sulfide stress cracking and hydrogen embrittlement. Electropolishing removes surface defects, elevates Cr:Fe ratio, and creates a dense passive layer that dramatically resists H₂S attack in NACE sour service environments.
Oilfield brines contain chloride concentrations that cause catastrophic pitting in standard stainless steel. Electropolishing removes micro-crevices and surface defects where Cl⁻ attack initiates — essential for downhole completion equipment and subsea hardware.
Subsea risers, wellhead components, and pipeline hardware experience constant pressure cycling and vibration fatigue. Electropolishing removes stress risers from machining that initiate fatigue cracks — extending service life of high-cycle pressure components.
LNG transfer systems, cryogenic valves, and cold box components operate at −162°C. Electropolishing provides a clean, burr-free surface with excellent low-temperature toughness — critical for reliable cryogenic sealing and leak prevention in LNG infrastructure.
Hydrogen sulfide causes sulfide stress cracking and hydrogen embrittlement in high-strength alloys — the leading cause of catastrophic oilfield equipment failures.
Produced water chloride concentrations of 100,000+ ppm cause catastrophic pitting and crevice corrosion in standard stainless — subsea equipment faces this 24/7.
Refinery process streams to 500°C+, wellhead pressures exceeding 15,000 psi, and combined thermal-pressure cycling that stress every surface defect.
H₂SO₄, HCl, HF, CO₂, methanol, glycol, and corrosion inhibitor chemical systems that attack unprotected metal surfaces across upstream, mid, and downstream operations.
Electropolishing improves surface quality and corrosion resistance of alloys specified for sour service — reducing susceptibility to sulfide stress cracking and hydrogen embrittlement in H₂S environments.

Electropolishing is a precise and controllable process for eliminating defects from the surface of metal parts. But it’s not the only finishing process available to manufacturers; there are mechanical, chemical and plating processes that can remove defects and improve the…
Metal fabrication for parts used in the medical and electronics industries can involve dimensions as small as a grain of rice — or even a strand of hair. At that scale, surface defects may be invisible to the naked eye,…
While stainless steel is known for its corrosion resistance, it contains iron, which is susceptible to corrosion, especially if parts are frequently exposed to moisture or harsh environments. Contamination left behind by machining processes can also impede the corrosion resistance…
