THERMODYNAMIC STEAM TRAPS DESCRIPTION: Thermodynamic steam trap with inbuilt strainer in full The trap will operate in any position but the preferred stainless steel construction, best suited for header and installation is in the horizontal plane with the disc cap on the main line drains and drip legs. top. Full port isolating valves should be installed upstream and downstream of the trap. Always open isolation valves FEATURES: Complete slowly until normal operating conditions are achieved to steel mechanical and corrosion resistance properties. The disc avoid system shocks. and seat are hardened by a special induction hardening process with seat harder than disc, to withstand continuous, This trap can be maintained without disturbing the piping prolonged operation. connections. Ensure that the trap is isolated - upstream Condensate entry below the disc, concentric to the disc/seat ensures a clean and parallel lift of the disc with reference to the seat, eliminating localized wear and tear. and downstream - before attempting to dismantle it. ALLOW THE TRAP TO COOL BEFORE DISMANTLING. For trouble-free performance, periodic cleaning of the disc, The inbuilt strainer screen is of adequately large area. seat and strainer screen is recommended. Do not use abrasive/corrosive media for cleaning. Only the Ideal for fluctuating loads and pressures. disc and seat are subject to wear. Perfect shut-off, no steam loss. A worn disc can be replaced. Slight seat wear can often be corrected by resurfacing on a lap plate. The trap should be installed as close as possible to the Screwed (NPT/BSPT/BSP) system drain point. Socket Weld/Flanged* For new installations, the system should be properly *End connection flanges of ASTM A105 forged carbon steel are welded on. flushed prior to fitting the trap.
