Contro trace - I don't know how much orientation you want or need. Contro trace is a pipe tracing alternative from Controls Southeast, Inc. in Charlotte, NC. The tracing is carbon steel pipe deformed to match the outside radius of the pipe to be traced. It has a flat side and a radius side. It offers a larger heat transfer surface than conventional tube tracing. It probably cost more than standard tracing. It would be good for lines that have to stay 'hot'.
