Examples: ControTrace Elements On Pipe
| Designed for 600 F (315 C) hot oil service, ControTrace
elements maintain uniform temperatures on stainless steel vapor lines in a polymer
process. Compared to fully jacketed pipe, the ControTrace Elements provided substantial
cost savings. Four ControTrace Elements are fitted to the 14-inch line. The elements heat
the elbows as well as the straight sections of pipe. |

| Standard weight piping was used on this heated 24-inch
vapor line. Design criteria called for the pipe wall to have uniform wall temperature
within 2-1/2 F (1.4 C). The heating medium was 300 psig (20.7 barg) steam at 400 F (217
C). If jacketed pipe had been used in this application, instead of the ControTrace Heating
Elements, the stainless pipe wall thickness would have been doubled in order to withstand
the external pressure created by the heating medium. |

A 12-inch transfer piping system in a sulfur terminal
utilizes four ControTrace Heating Elements to maintain 280 F (138 C) with 50 psig (3.4
barg) steam. Ball joints heated with ControHeat Bolt-On Jackets are used to manage the
expansion of the system as it grows from ambient temperature to the transfer temperature. |
