oil pipe tracing is not normally considered " critical", and where condensate is discharged to waste, a bimetallic trap or a balanced pressure thermostatic tracing trap can be used. this will conserve energy and prevent unsightly flash steam. However, if critical tracing considered essential, a thermodynamic or balanced pressure trap, discharging close to steam saturation, should be used.a convenient method of supplying steam to large numbers of tracer on process lines, and for draining condensate from them, is to use distribution and collection manifolds. these are shown in ABC , along with universal steam traps, and pipeline connectors with integral isolation valves . These allow traps to be changed quickly and without any downtime
