Introduction of SS304L Concentric Reducer
SS304L concentric reducer is applied to join pipe sections or tube sections on the same axis. The reducer is conc-shaped, and is used when it comes to a shift in diameter between pipes. For instance, when a 2" pipe needs to be transferred into a 3/4" pipe while the top or bottom of the pipe doesn't have to remain level, this pipe reducer may be used when there is a single diameter change or multiple diameter changes.
With a common center line, concentric reducers are useful when cavitation is available. Moreover, SS304L concentric reducers are created to meet the requirement of connecting pipe sections of different diameters in piping systems and align the center axis of both pipes.
Pipe fittings like reducers are crucial regarding to the flow rate and pressure of the fluid within the pipes, which ensures a smooth transition between different pipes of various sizes.

Chemical Composition
SS304 and SS304L have very similar properties in chemical and mechanical aspects. It is the carbon content that differentiates SS304 and SS304L which influences corrosion resistance. The SS304 has a maximum range of 0.08% whereas SS304L owns a maximum range of 0.03%. Thus, “L” in 304L can be interpreted as extra-low carbon.
