90/10 Reducer Fitting

Copper Nickel Reducer BW Seamless 90/10 CUNI Reducer 6”STD Fittings

The EEMUA 146 UNS 7060x Elbow is a common type of fitting that is used to change the direction of the flow in the system. These elbows are designed in short or long based on their radius of curvature. An EEMUA 146 Copper Nickel Long Radius Elbow has 1.5 times the radius of curvature than the outer diameter of the pipe. These elbows allow for a swift flow of media in different conditions. The EEMUA 146 Butt Weld End Caps are primarily used to close the ends of the hydraulic system to terminate the flow of fluids and gases. They also cut off contaminants from entering the grade. EEMUA 146 Stub End is a short piece of pipe having a flared end and can be used as an alternative to a standard flange.

WHAT IS CUPRO NICKEL FITTINGS?
The Tensile Strength of Cupro Nickel Fittings (rolled-H04 for flat products/ hard drawn-H80 for tubing) is 78000 psi (538 MPa). These Cuni Fittings has a Tensile Strength (annealed) of 52000 psi (359 MPa). Copper-Nickel Pipe Fittings are used in various application areas such as pipelines in shipbuilding, oil coolers, electrical resistors, steam turbine condensers, sprung contacts in relays, plug connectors and switches, auxiliary cooling systems and in a large number of cryogenic applications. The Chemical Composition of Copper Nickel Pipe Bend is Cu 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. The Molecular Formula of Copper nickel is ‎CuNi. Wall thickness chart help to select the various specifications and thickness of the various types of Cupro Nickel Long Stub that are available. The Thermal Expansion Co-efficient of Copper Nickel Pipe Fittings (@20-300°C/68-572°F) is 9.00 µin/in °F (16.2 µm/m °C). ANSI B16.9 Cu-Ni Welded Buttweld Fittings has a Shear Modulus (C71500 annealed) of 8300 ksi (57.2 GPa). Cupro Nickel 5D Bend are also used in conveying brackish water, clean seawaters and fresh water. Copper Nickel Bellmouth Fittings are also used in fasteners, boat hulls and in heat exchangers. Such Cuni Pipe Fittings also find use in high pressure pre-heaters at fossil fuel power plants and nuclear power plants and Copper Nickel Fuel Pipe Fittings for fuel systems.

Application:

• When the flow rate of the fluid in the pipeline changes, such as increasing or decreasing, and the velocity requirement changes little, it is necessary to use reducer.
• At the inlet of the pump, in order to prevent cavitation, reducer is needed.
• And the instrument, such as the flow meter, regulating valve joint, in order to cooperate with the instrument joint, also need to use reducer.
