It may not be related but I have to say this. In the earlier versions of Caesar II the weight of the equipment that needs to be carried by the spring hanger was not considered in the selection of hanger in Caesar II. So, the knowledgeable vendors did add the additional weight on to the cold pre-load to consider them in the spring application. Of course the will affect the hot load on spring as well.

In 2011 version of Caesar II the additional weight can be added. This is a good feature for especially small diameter piping and heavy appliances on them. But you need to know the additional weigh accurately. Otherwise the vendors again need to check the additional weight and make adjustment.

Hope this clarify some of the confusions.
