Abstract: Systems, devices, and methods for transferring heat associated with an interface corresponding to a reactor. In some aspects, a system includes a sleeve having a body portion that defines a channel that extends from a first end to a second end of the body portion. The channel is configured to define a flow path that extends through a flange that is coupled to a pipe via a welding point a lip portion extending radially away from the first end and configured to be positioned between the flange and a reactor.
