What is steam trap assembly?
Steam Trap Assembly. A steam trap assembly is an essential element of a steam distribution piping system. As steam flows through a pipe, Steam Trap Assemblies cool off due to heat losses and converts into hot water; this hot water is called condensate.
How do you install a steam trap in steam?
Locate the steam trap below the lowest condensate discharge point of the equipment. Never install a rise in the pipe ahead of a steam trap. Check valves should be installed after the steam traps in most applications. Develop and maintain installation standards for all applications.
How often should steam traps be installed?
every 30 to 50 meters
Even in cases where a steam distribution piping run is set in a straight line, steam traps should always be installed at least every 30 to 50 meters (100 to 160 ft), and at the bottom of risers or drops.
Where are steam traps required?
In Front of Pressure Reducing Valves and Control Valves A steam trap should be installed immediately before pressure reducing valves / control valves to prevent condensate from pooling when the valve is closed. The trap also helps reduce erosion of the valve seat from condensate.
Does a steam trap need a check valve?
Steam traps – Other than with steam traps discharging to atmosphere, check valves should always be inserted after a steam trap to prevent back flow of condensate flooding the steam space. The check valve will also prevent the steam trap from becoming damaged by any hydraulic shock in the condensate line.
What should be installed just ahead of a steam trap?
Always locate the steam trap below the lowest condensate discharge point of the equipment. Ahead of the steam trap, A rise in pipe elevation is not at all desirable. In most applications, check valves are installed after the steam traps.
What type of valve is steam trap?
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.
What are the common 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 you size steam traps?
Sizing. A large number of steam users improperly select trap size based on the size of existing piping. However, trap size should closely match the size of the piping on the outlet side of the equipment that supplies condensate to the trap.
How do you size a steam trap?
How do steam traps operate?
Mechanical steam traps operate by gravity. Specifically, the difference between the water and steam causes a stainless steel float ball to rise and sink within the trap, which opens and closes the valve.
Why are steam traps installed in steam lines?
Steam traps are very essential is power piping as these devices remove the unnecessary condensate from the steam lines. A steam trap serves two basic purposes: Separate the condensate from the steam as quickly as it is generated and stop the stream discharge.
Does a steam trap remove condensate?
A steam trap is a device that removes condensate from a steam system. A typical steam system will have many steam traps – they are placed at 50-150′ intervals in straight pipe, after every heat exchanger (where the work gets done), and at every location where there is a change of elevation or pressure.
How does a steam trap work?
A steam trap is a device used to discharge condensates and non-condensable gases with a negligible consumption or loss of live steam. Most steam traps are nothing more than automatic valves. They open, close or modulate automatically.
What is a steam condensate trap?
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.
