Syphon Pipe

Product Details:

Q Type Syphons are pressure instrument accessories used to protect pressure gauges, switches, and transmitters from direct contact with high-temperature steam, vapors, or fluids. The syphon forms a loop or "Q" shape that traps condensed fluid, acting as a cooling barrier between the hot process and the instrument.

Made from Stainless Steel (typically SS 304 or SS 316), Q-type syphons are ideal for corrosive and high-temperature environments such as steam pipelines, boilers, and chemical processing systems.

• Material: SS 304 / SS 316 / SS 316L – excellent corrosion and heat resistance

• Shape: Q-shape (closed-loop) for vertical or horizontal installations

• Purpose: Protects instruments from high temperature by allowing condensate to collect

• Connection Types:

  • Threaded (NPT / BSP / BSPT)

  • Socket weld or butt weld options available

• Pipe Schedule: Sch 40 / Sch 80 (as per pressure requirements)

• End Connection Size: Commonly 1/4", 3/8", or 1/2" (male x female or male x male)

• Protects pressure gauges and transmitters from direct heat

• Helps improve the accuracy and lifespan of instruments

• Easy to install and maintain

• Made from corrosion-resistant stainless steel

• Suitable for high-pressure steam and chemical applications

• Steam lines and boilers

• Power generation plants

• Petrochemical and chemical industries

• Refinery instrumentation

• HVAC and process piping systems

• Kalpataru Pipe & Fittings

Product Details:

A pigtail syphon is a coiled tube (often spiral-shaped like a pig’s tail) that allows steam or hot gases to cool down before reaching sensitive instruments. The coil traps condensed steam (condensate), forming a barrier that prevents direct contact between the hot process fluid and the gauge.

SS316 is an austenitic stainless steel known for:

• Excellent corrosion resistance, especially in chloride environments

• High temperature resistance

• Good mechanical strength

This makes SS316 ideal for harsh, high-temperature, and corrosive environments, such as:

• Steam lines

• Chemical processing

• Marine and offshore applications

1. Pigtail (Q-Type) – Spiral coil

2. U-Type – Horseshoe-shaped

3. Straight Syphon – With a simple bend

Pigtail syphons are the most common and compact design.

1. Installed between the process line and the pressure instrument

2. Filled with water or condensate

3. When hot steam enters, it condenses in the loop

4. The liquid layer prevents direct contact of steam with the instrument

• Protects gauges from overheating

• Extends instrument life

• Maintains measurement accuracy

• Resists corrosion in aggressive media

• Steam boilers

• Refineries

• Power plants

• Petrochemical units

• HVAC and process systems

Product Details:

A Stainless Steel Syphon (also known as a pigtail syphon or gauge syphon) is a mechanical device used to protect pressure gauges, switches, or transmitters from high-temperature steam or vapors. It acts as a thermal barrier, allowing condensate to form and cool before it reaches the pressure instrument.

• Protects instruments from steam burn-out or damage

• Reduces temperature before steam contacts gauge diaphragm

• Acts as a pressure pulse dampener

• Ensures longer service life for instruments

• Easy to install and replace

• Steam boilers and turbines

• Power generation systems

• Petrochemical and chemical process units

• Refineries and high-temperature pipelines

• Instrumentation panels in steam service
