Today there are more types of steam tracers to choose from than ever before, providing a range of conductance to closely match the actual heat requirements for a given pipe heating system. Steam tracing is a process that is designed to prevent heat loss as materials are moved through a plumbing system. A common application for this process is in the oil industry, where the plumbing at refineries is commonly fitted with steam tracing equipment.
