Span limits for elevated temperature piping

Pipe deflection due to self-weight quite often governs in the determination of the spacing between supports. Methods are readily available for calcula tion of elastic deflection of the pipe. However, such methods are not avail able for calculation of long-term deflection due to creep, which can be man y times the initial elastic deflection for pipe operating in the creep regi me of the material. Closed-form solutions for simple span conditions are pr esented which can be used by the analyst to develop charts for specific app lications. These solutions provide insights into the problem of establishin g span limits for elevated temperature pipe. [S0094-9930(00)01101-X].
