Multi-Stage Pump:

Material – ASTM A487, Grade CA6NM, Class A

A 12 stage split case pump is made up of three different castings: upper casing, impeller, and a lower pump casing. The parts are cast in martensitic stainless steel, which provides mechanical strength and superior corrosion resistance to endure the conditions of the nuclear environment.

2” Ball Valve Body

Material – ASTM B369, Grade C96400 (Cu-Ni 70/30)

Above is a high-pressure marine and NAVSEA application fluid delivery system component. SF&E will fully machine this item for our customer. We have strong expertise in casting valve bodies and other pressure retaining shapes to high specification applications.

Triple Offset Butterfly Valve Body Housing and Machined component

Material – ASTM A351, Grade CF3M (AISI 316L)

High specification, high criticality machined components, like the high-pressure fluid control valve above, can go through full non-destructive testing (NDT) evaluation if required.

Certified personnel are available on-site or from our high specification approved providers.
