A casing assembly is for a compressor including an internal compression assembly with a shaft and at least one impeller disposed on the shaft. The casing assembly includes an inlet body segment having a fluid inlet, an outlet body segment having a fluid outlet, and a number of intermediate body segments selected from a plurality of intermediate body segments. The intermediate segments are disposed between the inlet and outlet segments to form the casing and each has an inner circumferential surface defining an interior chamber section, the chamber sections collectively defining at least a portion of a compressor chamber sized to receive the compression assembly. The intermediate segment inner surfaces each have an inside diameter substantially equal to each other and the inner surfaces are generally coaxially aligned. As such, the inner surfaces collectively define a portion of continuous compressor support surface for supporting the compression assembly.
