MQA U N 1 T R A C E W a NEW SHAPE
W a n t to save money on steam-traced piping? Here's good news for your pocketbook! ALCOA® UNriTILACE has a new cost-cutting shape . . . a round section matching standard pipe shapes . . . available in 1 ^ " , 2 " , 3" and 4" sizes. With steam and product passages extruded in a single unit of light, strong, corrosion-resistant AJcoa aluminum alloy 3003-F, UNITRACE completely eliminates the cost o f external steam jackets or tracer tubes. And the new U N I T R A C E shape makes possible these extra savings: Lower cost per foot . . . total volume of metal is less; material costs are lower. Easier, faster joining „ . . new configuration (with exterior grooves for quick steam passage identification)
Sections of UNITRACE in the new shape can be easily and quickly joined by the w e l d and patch method (top). And a brand new UNITRACE flange—with product and steam passages cast as integral parts of the flange —simplifies installation of valves (center) a n d other flanged connections (bottom).
