VENTURI STEAM TRAPS Get a Quote
Home / Products

Product range

Every SteamEco trap is sized from your actual pressure and condensate load — we calculate each nozzle individually rather than selling a generic catalogue size. All bodies are stainless steel, flanged to your standard, and install at any angle.

SteamEco SE-D fixed-flow venturi steam trap
SE-D series · fixed flow

For heat exchangers, evaporators and reboilers

The workhorse for process duties with high and stable condensate loads. The multi-orifice nozzle package is calculated for your exact duty and can be exchanged when the plant is expanded or re-rated.

  • Continuous condensate discharge — no temperature or pressure cycling in the process
  • Precisely calculated nozzle prevents outlet erosion
  • No moving parts: no scheduled shutdown for trap inspection
  • Unaffected by thermal shock and water hammer
  • Internal parts replaceable to match future capacity changes
SE-Z series · combined, low capacity

For saturated & superheated steam mains

A venturi element combined with a bimetallic element, built for steam distribution and tracing lines where live steam loss is the main cost driver. The wide working range tolerates pressure fluctuation across the whole header.

  • Zero steam leakage — measured, not assumed
  • On-line adjustment without removing the trap from the line
  • Bimetallic element works at low thermal stress, extending service life
  • Strainer element can be pulled and cleaned in minutes
  • Compact inline body for congested pipe racks

For loads that change with the batch

Heating and holding kettles, batch cookers and any duty where condensate load swings widely. Capacity is adjusted on-line with a spindle that preserves the venturi flow characteristic across its travel.

  • Flow capacity adjustable on-line — no line break-in
  • Spindle geometry maintains venturi performance at every setting
  • Steam leakage rate below 0.1%
  • Rugged, one-piece construction — no routine maintenance
Integrated solution

Steam tracing manifold & condensate collection station

A prefabricated vertical module that combines the steam distribution header, condensate collection header, pre-insulated tracing bundles and a valved trap station in one forgeworks assembly in 304 stainless steel.

  • Modular standard design — no site fabrication
  • Fewer field welds, fewer potential leak points
  • Integrated trap valve: two isolating valves, filter-type trap, drain and check valves
  • Fitted with venturi + bimetallic combined traps — zero steam loss
  • Saves space and installation man-hours on pipe racks

Selection guide

Which series fits your application?

Application Recommended series Why
Heat exchangers, evaporators, reboilers, air heaters SE-D High, stable condensate load; continuous discharge keeps heat transfer at its best
Saturated & superheated steam mains, headers SE-Z Zero leakage on lines where traps run light but constantly
Steam tracing bundles and jacketed piping SE-Z / tracing station Low capacity, wide range; prefabricated station cuts installation cost
Batch kettles, heating/holding vessels, sterilisers SE-DT Load swings handled by on-line capacity adjustment
High-pressure service up to 9.0 MPa, flows to 156 t/h SE-D / SE-DT Proven on a PTA main plant at 9.0 MPa and 156 t/h
Technical data

Typical specification envelope

Body material

304 / 316 stainless steel, forged or cast; flanged ends per EN / ASME / GB standard

Pressure range

Low pressure to 9.0 MPa — nozzle calculated per operating point

Capacity

From a few kg/h on tracing up to 156 t/h on PTA high-pressure duty

Steam leakage

≤ 0.1% (SE-DT); effectively zero on SE-D / SE-Z in normal operation

Installation

Any orientation — horizontal, vertical, inverted; no elevation head required

Service life

10–20 years body life; warranty 3–10 years depending on series and duty

Maintenance

No scheduled inspection or shutdown; SE-Z strainer cleaned in line

Tests before delivery

Hydrostatic shell test + hot steam operational test, per GB/T 12251 & 22654

Drop-in replacement

SteamEco traps keep the same function, flange dimensions and connection sizes as the mechanical traps they replace — float, inverted bucket or thermodynamic. No piping modification, no re-rating of supports, just bolt it in.
