NACE MR0175 Sour Service High Speed Centrifugal Pump CRA Clad API 610 OH6 45 M3/Hr
NACE MR0175 Sour Service
,CRA Clad API 610 Pump
,High Speed Centrifugal Process
Product Description
Specifically engineered for upstream and downstream sour hydrocarbon services containing hydrogen sulfide, this high speed centrifugal pump meets stringent NACE MR0175/ISO 15156 material requirements for sulfide stress cracking resistance. Corrosion-resistant alloy (CRA) weld overlay on all wetted surfaces ensures long service life in aggressive sour environments.
