It is an ASME B31.1 requirement that piping systems be designed to comply with the load limits of equipment to which they are connected. This equipment can be machinery, pressure vessels, heat exchangers, as well as a myriad of other possibilities. The designer needs to be aware of the applicable load limits. Some are described herein as examples; however, this is not a complete list. The remainder of this chapter does not provide specific Code requirements; it provides general information on load limits for equipment.
