Do may be different for other manufacturers. Thermal expansion characteristics and required loop lengths will vary between manufacturers. Source Fibercast Piping Design Manual FC-680 p. 6. 7-2. Reinforced Epoxies Although epoxies cure without the need for additional heat almost all pipe is manufactured with heat-cure. Reinforced epoxy piping systems are not manufactured to dimensional or pressure standards. Therefore considerable variation between manufacturers exist in regard to available size maximum pressure rating and maximum temperature rating. Performance requirements including manufacturing conforms to ASTM standards in order to not sole-source the piping system. 7-3. Reinforced Polyesters Reinforced polyester thermoset piping systems are the most widely used due to affordability and versatility. The maximum .
