Thermodynamic Steam Traps

DESCRIPTION:
Thermodynamic steam trap with inbuilt strainer, 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 ensures a clean and parallel lift of the disc
with reference to the seat, eliminating localized wear
and tear.
The inbuilt 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
*End connection flanges of ASTM A105 forged carbon steel are welded on.

Non IBR1 / IBR approved

LIMITING CONDITIONS:
PMA: Max. allowable pressure
TMA: Max. allowable temp.

42 bar (g)
426 ºC

Maximum operating back pressure at the outlet should
not exceed 80% of the inlet pressure.
Minimum differential pressure
for satisfactory operation
Cold hydro test pressure

0.25 bar

MAINTENANCE:
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.

84 bar (g)

IMPORTANT:

INSTALLATION:
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.

Indian Boiler Regulations

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.
