ABSTRACT:
In a freight container the tank is joined via saddle means to end frames which are provided with the standardized corner fittings which are normally used in container design and determine the outer dimensions of the container. Each saddle means in its simplest form consists of a cylindrical end ring welded to the relatively less curved spherical main portion of the tank end portion surrounded by the highly curved knuckle zone, and of a saddle ring of L-shaped cross-section having its radially extending flange secured to the end frame and/or diagonal struts thereof and its second flange extending in tank axial direction welded to the end ring. This structure permits a strong connection between the tank and the end frame, while the loads transmitted by the tank are almost completely directly introduced into the corner areas of the end frame. At the same time it permits the "breathing motions" occurring on account of temperature and pressure variations in the knuckle zone of the tank end portion. The relatively large angle at which the end ring joins the tank end portion avoids recesses which would not be readily accessible and therefore be susceptible to corrosion.
