摘要: The disclosure provides a heat transfer system having tubing coil for heating fluid flowing therein, where the can be pigged (descaled) while operationally online, instead of offline. online uses an assembly valves and associated equipment to connect pig launcher receiver is online. A valve opens launches into flow stream under pressure through travels along tube with fluid. continues produce heated in path. receives after pigging, then isolated from path by another valve. launcher, receiver, are removed, this process repeated any other passes coil.
