Worthington Service Water
Application: Service Water
Pump Details: Worthington 16QL 20
Pump Type: Multi-Stage Vertical
When Hydro received this service water pump from a power plant, all the components, including the column pipe, inner tubes, casing and suction bells, were sandblasted and cleaned so that a thorough inspection could be performed.After cleaning, these components were subjected to a non-destructive examination and liquid dye penetrant check. This process revealed some serious indications in the form of cracks near the flanges. These cracks were identified in three of the four pipes and went through the wall thickness. They were sufficiently long enough to be potentially catastrophic if left undetected and unrepaired. The cracks were weld repaired and machined to the proper dimensions and contour.
Hydro's dimensional inspection also showed that the alignment fits between components were loose and out of round and that flange faces were not parallel to each other. Hydro repaired these alignment fits and machined the flange faces to restore concentricity and perpendicularity to within 0.002". Hydro's comprehensive inspection enabled the plant to avoid a potentially catastrophic failure and all of the costs associated with such an unplanned outage.
