Design pipe-heavy wall

Valve Loading. The designer should be particularly careful in using low pressure rating valves with relatively heavy-walled pipe. The imposed moment caused by construction or by expansion may be beyond the structural capacity of the valve. For large-diameter piping, venturi ports are sometimes used on valves (particularly when motor operated). Also, standard valves one or two sizes... 

Figure 3-61. Variables involved in pipe-design problems. The upper-left drawing is used to analyze problems involved in spacing pipe supports the lower drawing deals with designing thin-wall tubing to contain an internal pressure the drawing at the right covers the analysis of heavy wall piping under pressure.
