In industrial systems where pressure and temperature monitoring are critical, protecting
instruments is just as important as measuring accurately. One such essential component used
across industries is the syphon (siphon tube).
At Arrotop, we specialize in manufacturing high-quality instrumentation components including
syphons, valves, manifolds, and pipe fittings, designed to ensure safety, accuracy, and
long-term reliability in demanding environments.
Syphons are widely used to safeguard pressure instruments from high-temperature media such
as steam, making them an indispensable part of many industrial setups.
What is a Syphon?
A syphon is a simple yet highly effective device installed between a pressure instrument (like a
pressure gauge) and the process line. Its primary function is to protect the instrument from
direct exposure to high-temperature fluids, especially steam.
It works by creating a condensate barrier inside its loop or coil, which prevents hot media from
reaching the instrument directly.
How Does a Syphon Work?
When steam or hot fluid enters the syphon:
- It cools down and forms condensate inside the loop
- This condensate acts as a protective buffer
- The pressure is transmitted to the instrument without exposing it to extreme temperatures
This ensures accurate readings while significantly increasing the life of the instrument.
Types of Syphons
At Arrotop, we manufacture different types of syphons to suit various industrial requirements:
P-Type Syphon
- Designed in a loop shape
- Commonly used in horizontal installations
- Ideal for general steam applications
Coil Type Syphon
- Spiral or helical design
- Provides enhanced cooling
- Suitable for high-pressure and high-temperature systems
U-Type Syphon
- Simple U-shaped design
- Used in compact installations
- Suitable for vertical mounting
Applications of Syphon
Syphons are used across multiple industries where pressure instruments need protection from
high-temperature fluids.
- Steam Systems : Syphons are most commonly used in steam lines to protect pressure gauges from direct steam exposure.
- Power Plants : In thermal and power generation plants, syphons are used in Boiler systems, Steam pipelines, Pressure monitoring units
- Oil & Gas Industry : Used in high-temperature pipelines and processing units where accurate pressure measurement is critical.
- Chemical & Petrochemical Industries : Syphons help protect instruments from corrosive and high-temperature fluids used in chemical processing.
