It was carried out the theoretical evaluation of the effect of dimensions of combined hollow cylindrical castings on the allowable pressure p v when they are loading with the working body from the inside out. It was found that in combined castings value of p v depends on a number of their designs-structural factors which must be considered in the design of a particular combined related casting. Thus, among the studied factors the most significant is the magnitude of interference and wall thickness of the casting.
