Condensate Steam Pot
In steam and vapor services, the accuracy and longevity of your differential pressure (DP) transmitter depend entirely on a stable and consistent condensate level. Samvay Fluid Tekniks Inc. presents our premium range of Condensate Pots (also known as Seal Pots, Condensing Chambers, Steam Pots, or DP Transmitter Seal Pots), engineered to provide a reliable reference head and protect sensitive instrumentation from direct process exposure.
Product Overview
Condensate pots are essential components in steam flow measurement applications. Installed in the impulse lines near the tapping point on steam pipes, they serve two critical functions:
Create a Constant Head: Steam entering the pot condenses, forming a uniform liquid column that transmits pressure to the DP transmitter without the fluctuations caused by live steam or partial condensation in impulse lines.
Protect Instruments: The condensate barrier prevents high-temperature steam, entrained particles, scale, and corrosive media from reaching the sensitive diaphragm of the transmitter, extending instrument life and maintaining accuracy.
Why Condensate Pots Are Essential:
Without a properly designed and installed condensate pot, DP transmitters on steam service would experience:
Problem
Consequence
Erratic Readings
Steam condensation in impulse lines causes varying density and pressure transmission
Thermal stress and fatigue from direct steam exposure
Blockage
Scale and debris from steam lines entering transmitter
Freezing
Condensate freezing in impulse lines during winter
Measurement Errors
Fluctuating reference head affects accuracy
Samvay condensate pots are designed for both vertical and horizontal mounting, offering flexibility in tight spaces while maintaining optimal performance. Each pot is manufactured to ASME standards and fully tested before dispatch.
All Samvay condensate pots are designed in accordance with ASME Section VIII Division 1, the internationally recognized standard for pressure vessels. This ensures:

Calculation Methodology:
Our engineers perform detailed calculations for every pot:
Shell Thickness: Based on design pressure, diameter, and material allowable stress
Head Thickness: For formed heads (if applicable)
Nozzle Reinforcement: For all openings
Weight Calculation: For lifting and support design
Volume Calculation: To ensure adequate condensate capacity

Installation Guidelines
Location & Orientation:
Vertical Mounting (Preferred):
Install with process connections on top, drain at bottom
Ensure pot is vertical (±5°)
Locate as close as possible to tapping point (within 12″)
Slope impulse lines downward from pot to transmitter (minimum 1″ per foot)
Provide adequate support for weight of pot and fill of condensate
Horizontal Mounting (Space-Limited):
Install with process connections on side
Ensure slight upward slope toward process tapping (1/4″ per foot)
Provide additional support at both ends
Consider drain connection location for complete draining
Installation Steps:
Mount the Pot: Secure to pipe, wall, or support structure using appropriate brackets
Connect Process: Install piping from process tapping to pot inlet(s)
Install Valves: Add isolation valves at process connections (recommended)
Connect Impulse Lines: Run tubing/pipe from pot outlets to transmitter
Install Drain Valve: At bottom for maintenance and commissioning
Fill with Water: Before start-up, fill pot with water through vent or drain
Vent Air: Open vent to release trapped air during filling
Insulate (if needed): For outdoor or freeze-prone locations
Pre-Startup Checklist:
Item
Check
Pot securely mounted
☐
All connections tightened
☐
Drain valve closed
☐
Vent valve closed
☐
Pot filled with water
☐
Impulse lines connected
☐
Transmitter manifold installed
☐
Insulation applied (if required)
☐
Common Mistakes to Avoid:
Mistake
Consequence
Prevention
No initial water fill
Steam hits transmitter directly, thermal shock
Always pre-fill with water
Incorrect orientation
Incomplete condensate formation, erratic readings
Follow mounting instructions
Too far from tapping
Lag in response, condensation in lines
Install within 12″ of tapping
Upslope to transmitter
Air pockets, erratic transmission
Slope down from pot to transmitter
No insulation
Freezing in winter, heat loss
Insulate in cold climates
Undersized pot
Insufficient volume, fluctuating head
Calculate required volume
No drain valve
Difficult maintenance, cannot drain
Always provide drain
Winterization:
Insulate pot and impulse lines
Add heat tracing (electric or steam)
Use heat-transfer cement on tracing
Consider heated enclosures
Use freeze-protected instrument manifolds
Example: For 15 feet of 1/2″ tubing (ID = 0.5″) Volume per foot = π × (0.25)² × 12 = 2.36 in³/ft Total volume = 15 ft × 2.36 in³/ft × 2 lines = 70.8 in³ (1.16 Liters) Required pot volume = 1.16 × 10 = 11.6 Liters minimum
