Investigation about the effects of exterior surface paint color on temperature development in aboveground pipeline

Temperature variation in steel box girders of cable-stayed bridges during construction

“…It ranges from 0 to 1 and varies according to the surface condition. Even though a steel girder would have a high absorption coefficient, the value can be significantly reduced by painting the external surface [16,17]. The total solar radiation (I t ) can be divided into beam radiation, diffuse radiation, and reflected radiation.…”
