Abstract
Official abstract text for this publication.
A piping component for controlling the flow of high-temperature fluids that includes a piping body having an inlet end and an outlet end, including methods of operating such components within a piping system. The piping body may be sized for fluids operating at temperatures from approximately 350° F. up to approximately 500° F., and 650° F. The piping body may also be sized for high-temperature fluids (e.g., steam) operating at pressures of up to approximately 400 psi, and 600 psi. In addition, the piping body is made from a silicon-copper alloy consisting essentially of less than 16% zinc, less than 0.25% lead, less than 0.25% bismuth, 2 to 6% silicon and a balance of copper (by weight).
First claim
Opening claim text (preview).
We claim: 1. A piping component, comprising: a piping component for controlling the flow of fluids, the piping component comprising a piping body having an inlet end and an outlet end, wherein the piping body is sized for fluids operating at a temperature from approximately 350° F. up to approximately 500° F., and further wherein the piping body is made from a silicon-copper alloy consisting essentially of less than 4% zinc, less than trace amounts of lead, less than trace amo…
