How are modern conduction tracers installed on pipelines?
In a modern conduction tracing system, the tracer and heat transfer compound are completely covered and held in place by “Strap-On” galvanized steel or stainless steel jackets (sometimes referred to as channels). The steam tracers are held firm and always in contact with the pipeline due to the restraining action of the heat transfer compound surrounding the tube and the Strap-On metal jackets that are held in place by stainless steel straps tightened with a force of up to 4,448 N (1000 lbs). The tightly attached Strap-On jackets assure that the steam tracers and heat transfer compound are permanently fixed to the surface of the pipeline. Short sections of the jacket may be miter cut and placed over the tracer and heat transfer compound at elbows and bends to permanently hold the tracer against the pipe at these locations or, “flexible” stainless steel jackets are available for any irregular shapes such as elbows, valves, pumps or other equipment.
