45 SR and 90 LR are different bend angles of the pipe fittings.45 SR Incoloy 825 pipe fittings have a 45 degree angle, and the radius of the curve is relatively short.These fittings are used when a more compact bend is required in a space-saving environment.
90 LR incoloy 825 fittings have a 90-degree angle, and longer radius of the curve than SR bends.It is used when a smoother flow path and reduced pressure drop are desired.
Inconel 825 3D & 3R elbow has different bend radius and final shape.A 3D Alloy 825 elbow has a larger bend radius than 3R ones.It has three times the pipe diameter which indicates a relatively larger curve.These alloy 825 fittings have a smoother and more gradual bend which reduces flow resistance and pressure drop.
A 3R elbow Inconel 825 fittings have has bend radius three times the pipe diameter.They create a sharper bend which results in higher flow resistance and increased pressure drop.

DIN 2.4858 reducer
A popular Incoloy 825 buttweld fittings are eccentric & concentric reducers.They can connect pipes of different diameter in a system.Some differences between them will include:
A nickel alloy 825 concentric reducer has a cone shape.Their larger and smaller ends are aligned along the same central axis.It reduces the pipe diameter and maintains a straight and even flow path.These Incoloy alloy 825 fittings are used for maintaining the same fluid flow direction.
A DIN 2.4858 eccentric reducer is asymmetrical in shape with one larger and a smaller end which is not aligned along the same central axis.These alloy 825 seamless fittings maintain help to avoid air or solids from getting trapped in the piping system.
