Steam Manifolds are used for steam distribution in tracing applications for condensate collection. Typically used in chemical plants, petrochemical plants, textile industries, rubber plants and general industry.
How does a steam trap work? steam trap – Self contained valve which automatically drains the condensate from a steam containing enclosure while remaining tight to live steam, or if necessary, allowing steam to flow at a controlled or adjusted rate. Most steam traps will also pass non-condensable gases while remaining tight to live steam.
Also, What is steam tracing in piping? Steam tracing is a form of heat tracing that circulates steam around process pipes to keep the process media within a specific temperature range. Tracer lines are the tubing that carries the steam alongside the process pipe. Both electrical heat tracing and steam tracing are commonly used at process plants.
Where steam trap are used?
Steam traps are a type of automatic valve that filters out condensate (i.e. condensed steam) and non-condensable gases such as air without letting steam escape. In industry, steam is used regularly for heating or as a driving force for mechanical power.

How hot is steam tracing?
Depending on the temperature requirements of the fluid in the pipe different levels of steam pressure can be used for tracing. Representative temperatures for high, medium, and low steam pressure are 150–180°C, 200–270°C, and 350–400°C.
What is contro trace?
Specially designed by CSI, ControTrace is an economical alternative to jacketed pipe. Specially designed by CSI, ControTrace is an economical alternative to jacketed pipe while also providing substantially more heating capacity than tube tracing. Formed from SA178 Gr.
Why do you need a steam trap?
The steam trap is an essential part of any steam system. It is the important link between good steam and condensate management, retaining steam within the process for maximum utilisation of heat, but releasing condensate and incondensable gases at the appropriate time.
What condensed steam?
Steam that has been condensed back into water by either raising its pressure or lowering its temperature. Not to be confused with demineralized, de-ionized, make up, or softened water.
What are types of steam traps?
Steam traps can be split into three major types:
- Mechanical traps. These remove condensate through the use of the mechanical properties of steam vs condensate. …
- Thermostatic traps. These remove condensate through the temperature difference of steam vs the liquid phase. …
- Thermodynamic traps.
How do I choose a steam trap?
In order to select the correct steam trap to suit your application, it needs to be properly sized and the following conditions must be known: • operating inlet pressure • operating outlet pressure or back pressure • differential pressure (i.e. the difference between the inlet pressure and the outlet pressure) • flow …
Which type of steam trap is often not desirable?
Temperature Steam Traps
In some exceptional circumstances, this is not desirable if condensate needs to be removed as soon as it is formed.
What is jacket piping?
Jacketed piping is a double-walled pipe. The special devices are used to control the distance between two pipes – spacers, guide plates, partition/end plate and spiders. Spacers support the core pipe from jacket pipe and to ensure uniform gap between core and jacket pipes.
Why is heat tracing needed?
Heat trace system is necessary for cold conditions where the liquid flowing within pipes are prone to freezing. As discussed earlier, freezing within the pipes can damage the entire piping system. … By using a Chromalox’s heat trace system, we can keep the pipes warm even when the surrounding temperatures plummet.

What is jacketed pipe?
Jacketed piping is a double-walled pipe. The special devices are used to control the distance between two pipes – spacers, guide plates, partition/end plate and spiders. Spacers support the core pipe from jacket pipe and to ensure uniform gap between core and jacket pipes.
Can a steam trap be oversized?
A failed oversized trap has a larger orifice opening that can potentially blow through larger quantities of steam and waste more energy. Steam traps should generally be sized two to three times the amount of condensate that will be produced under normal operation to account for varying pressures and condensate loads.
How long does a steam trap last?
Steam traps last approximately six years. Leaks may not be visible, so thermal imaging can be used as a testing measure. Repairing or replacing failed steam traps will improve steam system efficiency and occupant comfort, while reducing the amount of natural gas required.
How do you monitor steam traps?
Steam traps can be tested by going to each steam trap and listening to the operation by using an ultrasonic instrument and/or using a sophisticated heat gun to check the temperature.
What happens when steam condenses to water?
Without heat, the water molecules inside the bottle start condensing—that is, they start turning from steam back into liquid water. When matter turns from its gas phase back into its liquid phase, the molecules take up much less space and exert far less pressure.
What happens to the steam during condensation?
Like the phase change from ice to water, the process of evaporation is also reversible. The same amount of heat that produced the steam is released back to its surroundings during condensation, when steam meets any surface at a lower temperature.
How does the steam condenses back to water?
When water is heated it evaporates, which means it turns into water vapor and expands. At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created. The opposite of evaporation is condensation, which is when water vapor condenses back into tiny droplets of water.
What is thermostatic steam trap?
Thermostatic steam traps operate on steam’s temperature difference from cooled condensate and air. Steam increases the pressure inside the thermostatic element, causing the trap to close. … The amount of condensate backed up ahead of the trap depends on the load conditions, steam pressure and size of the piping.
What is a mechanical steam trap?
Mechanical traps are steam traps that operate on the principle of specific gravity (specifically the difference in the specific gravities of water and steam), unlike other types of steam traps that rely on temperature change or velocity/phase change.
