6.3.3   IP exhausts


IP cylinders generally have two or four inlets arranged in a similar manner to the HP.

The IP exhaust positions are determined by the positions of the crossover pipes to the LP inlets. With underslung condensers, the LP inlets and crossovers are usually on the top half, hence IP exhausts are also at the top. However, arranging IP exhaust and LP inlet pipes in the lower half casing reduces the amount of pipework to be disconnected when cylinders are opened, and is thus easier if the condenser arrangeĀ­ment allows it.
