Thermodynamic Steam Traps

Pennant Engineering offers a range of thermodynamic steam traps. Model PT11 in full stainless steel construction, best suited for header and main line drains and drip legs. Features: complete stainless steel construction ensures better mechanical and corrosion resistance properties; the disc and seat are hardened by a special induction hardening process with seat harder than disc, to withstand continuous, prolonged operation; condensate entry below the disc, concentric to the disc/seat and the three port design ensures a clean and parallel lift of the disc with reference to the seat, reducing localised wear and tear; the in-built strainer screen is of adequately large area; ideal for fluctuating loads and pressures, perfect shut-off, no steam loss; sizes – DN15, 20, 25; connections – screwed (NPT/BSPT/BSP) flanged, socket weld, non IBR/IBR approved; limiting conditions PMA – max allowable pressure – 42 bar (g); TMA – max allowable temperature – 426°C; maximum operating back pressure at the outlet should not exceed 80% of the inlet pressure; minimum differential pressure for satisfactory operation – 0.25 bar; and cold hydro test pressure – 84 bar (g). The trap will operate in any position but the preferred installation is in a horizontal position with the disc cap on the top. Full port isolating valves should be installed upstream and downstream of the trap. This trap can be maintained without disturbing the piping connections. Ensure that the trap is isolated – upstream and downstream – before attempting to dismantle it. Allow the trap to cool before dismantling. For trouble-free performance, periodic cleaning of the disc, seat and strainer screen is recommended. Do not use abrasive/corrosive media for cleaning. Only the disc and seat are subject to wear. A worn disc can be replaced. Slight seat wear can often be corrected by resurfacing on a lap plate. Important: the trap should be installed as close as possible to the line to be drained. For new pipelines, ensure that the lines are properly flushed, prior to fitting the traps, to avoid strainer choke-up.
