Insulation thickness shall be in accordance with the Thermal Insulation Design Specification (SP-006) based on the operation temperature of the line to be traced. 2.1.4. Typical steam tracing piping system is as shown in Figure 1 of Attached figures. 2.2. Materials 2.2.1. Pipes, Valves and Fittings In general specifications of piping materials for steam tracing shall be the same as those applicable to the steam mains. However, the tracer (including tracer supply and return) may be connected with butt-weld and the branch of manifold fabricated with nozzle weld.
