Hot liquid is flowing in a steel pipe with a 22-mm inner diameter and a 27-mm outer diameter. The pipe outer surface is subjected to a uniform flux of 1200 W/m2 for a length of 1 m. The pipe inner surface is coated with a thin polyvinylidene fluoride (PVDF) lining. The hot liquid flowing inside the pipe has a mean temperature of 120°C and a convection heat transfer coefficient of 50 W/m2•K. The ASME Code for Process Piping (ASME B31.3-2014, A323) recommends a maximum temperature for PVDF lining to be 135°C. Does the surface temperature of the PVDF lining comply with the recommendation of the code?
