Ensuring Uniform Heat Distribution in Process Piping Controls Southeast, Inc.

<<A look at two case histories shows how a bolt-on heating system provides more uniform temperatures on process piping. Certain hot process piping services require thermal maintenance devices to keep stream temperatures within design limits. In such cases, conventional pipe jacketing has been regarded as sufficient but often too expensive. An alternative to pipe jacketing, tube tracing, does not effectively prevent problems caused by temperature variations along the process pipe wall. Frequently, tube tracing is used as an economical way to try and compensate for heat loss. In low temperature applications with broad temperature envelopes, steam tracing can be effective. However, in those applications, the position of the tracers and the temperature distribution in the pipe material are not considered important.>> Received on Thu Dec 14 05:53:00 2000
