    摘要： A connection socket for a tubular connection includes a socket cup having a metal alloy composition and a sealing portion. A primary seal is positioned within the sealing portion. The primary seal includes an elastomeric material having a service temperature. One or more spacer rings are positioned within the sealing portion. A secondary seal is positioned within the sealing portion. The secondary seal includes a metal composition, wherein the secondary seal has a melting temperature at or above the service temperature of the primary seal. One or more locking rings are positioned within the sealing portion, wherein each of the one or more locking rings comprises a biting feature defined along an internal circumference of the locking ring.

    摘要： A piping component for controlling the flow of 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 up to approximately 650° F. In addition, the piping body is made from a silicon-copper alloy consisting essentially of less than 16% zinc, less than trace amounts of lead, less than trace amounts of bismuth, 2 to 6% silicon and a balance of copper (by weight). In certain aspects, less than 0.09% of lead and/or less than 0.09% bismuth are contained in the silicon-copper alloy.

    摘要： A method of making a corrosion resistant brass component that includes the steps: forming a gaseous atmosphere containing labile sulfur by combustion of potassium bisulfate or hydrogen sulfide; and contacting surfaces of a finished brass component with the gaseous atmosphere containing labile sulfur. The surfaces of the brass component are contacted with the gaseous atmosphere at an elevated temperature for a time sufficient to form a metal-sulfide rich layer of at least 5 microns in thickness. Further, the brass component is corrosion resistant after the contacting step as determined by standardized testing that yields dezincification penetration of less than 200 microns in depth.

    摘要： 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).

    摘要： Copper alloys exhibiting enhanced oxidation resistance are provided by adding an amount of sulfur that is effective to enhance oxidative resistance. Such sulfur addition can be achieved by combining elemental forms of copper and sulfur and heating the mixture to form a molten alloy, or by forming a sulfur-rich pre-mix that is added to a base alloy composition. Forming a pre-mix provides improved homogeneity and distribution of the sulfur predominantly in the form of a metal sulfide.
