Simpler tube tracing installation
The PT Series 46-TT Tube Tracing Bimetal Trap is specifically designed for steam tracing applications. Both ends of the trap come fitted with compression tube fittings, which simplifies installation in several ways:
- Removes the need to install tube-to-male NPT fittings in the field.
- No more crimped or bent tubes from the high torque required to tighten piped joints in the field.
- Eliminates two unnecessary steam leak paths at the pipe joints between tube and pipe fittings, and the need for messy Teflon tape or pipe sealant.
- Leak-free trap installation takes less than five minutes.
Design features
The Series 46-TT is backed by the proven field reliability of standard PT Series 46 Bimetal Steam Traps:
- 300 psig and 750 °F operating pressure and temperature.
- Subcooled condensate discharge, eliminating steam loss and maximizing energy efficiency.
- Large orifice coupled with back-seated valve, ensuring optimum dirt and particle handling.
- Bimetal operating principle, providing self-venting, freeze proofing, resistance to water hammer and superheating, and fail-open safe operation.
All of these features come in a single, compact, all stainless steel trap, available with 1⁄4", 3⁄8" and 1⁄2" tube fitting ends, and backed by an industry-first, full five-year manufacturer's warranty against workmanship and functional defects.
