Api 610 13th Edition Fix Jun 2026

For services involving hydrogen sulfide (sour service), API 610 mandates materials that comply with (“Petroleum, petrochemical and natural gas industries – Materials for use in H₂S‑containing environments in oil and gas production”). The standard includes material selection tables (e.g., Table H) covering casings, impellers, shafts, and fasteners, with specific grades of carbon steel, stainless steel, and duplex stainless steel. The 13th Edition may update these tables to reflect newer alloys and stricter environmental regulations.

Cantilever-style rotors where the impeller is mounted on the end of the shaft. These can be foot-mounted (OH1) or centreline-mounted (OH2) to handle high thermal expansion. Api 610 13th Edition

Pump casings must be subjected to hydrostatic tests at 1.5 times the maximum allowable working pressure (MAWP) to ensure structural integrity. For services involving hydrogen sulfide (sour service), API
