Seawater pumps need the right materials for corrosiorreontrol

摘要

As more production moves offshore and existing fields mature,the number of pumps handling seawater applications is increasing.Vertical turbine pumps offer a flexible design to accommodate any system by multi-staging.The ease of changing the stag-ing on the pumps is also an advantage if it becomes necessary to change the hydraulic characteristics of the system.Stages can be added to the same pump if changes in the system head curve result from an increase in pipe friction due to corrosion.This condition is quite common in seawater svstems.
