Thoughtful consideration Bruce,
Have not seen this called out in the spacing calculation. In general for average temperature (say, about 50 deg C above ambient) lines the gap allowed in the spacing may have this provision inherent. It is indeed necessary to consider this when there are above average temperature lines.

thermal expansion at those points will affect the pipe spacing
