Hybrid intake screen assembly
An intake screen assembly including an intake member, a screen support member, and a screen member coupled to the screen support member. The screen member may be formed from a material, such as copper-nickel, that is different from a material, such as stainless steel, used to form the intake member and/or the screen support member. The intake screen assembly may include corrosion protection members for preventing contact between the components of the screen assembly that are formed from dissimilar materials. The assembly may be formed by coupling the screen support member to the intake member, and coupling the screen member to the screen support member.
1. A support structure for a water intake assembly, the support structure, comprising:
a plurality of circumferential supports defining a cylindrical cage structure, said plurality of circumferential supports including an innermost circumferential support, an outermost circumferential support and a plurality of intermediate circumferential supports located between the innermost and outermost circumferential supports;
one or more straight reinforcing bars extending between the innermost circumferential support and the outermost circumferential support, wherein said one or more straight reinforcing bars do not contact the plurality of intermediate circumferential supports.
2. The support structure of claim 1 , wherein a first end of the one or more straight reinforcing bars is coupled to the innermost circumferential support and a second end of the one or more straight reinforcing bars is coupled to the outermost circumferential support.
3. The support structure of claim 1 , wherein the plurality of intermediate circumferential supports are undersized relative to the innermost circumferential support and the outermost circumferential support.
4. The support structure of claim 1 , wherein one or more straight reinforcing bars extend in a zig-zag pattern around a circumference of the cylindrical cage structure.
5. An intake assembly, comprising:
an intake member including a lower portion for operable connection to a flow line and an upper portion operably supporting the support structure of claim 1 .
6. The intake assembly of claim 5 , further comprising one or more screen panels mounted to the cylindrical cage structure.
7. The intake assembly of claim 5 , wherein the upper portion defines a tee-section, said tee-section operably supporting a pair of the cylindrical cage structures.
8. The intake assembly of claim 7 , further comprising one or more screen panels mounted to each of the cylindrical cage structures.
