Application scenarios
Steam trap condition monitoring integrated with existing Spiratec systems
The IBPC32 incorporates a Spiratec sensor for convenient integration with existing Spiratec monitoring systems. When fitted with WLS1, it can detect waterlogging and steam leakage; when fitted with SS1, it can detect steam leakage, enabling monitoring of steam trap operating condition.
Selection points
Integrated Leakage and Condensate Backup Monitoring Sensor Options
Can be configured with an integrated WLS1 sensor for condensate backup and steam leakage detection, or an integrated SS1 sensor for steam leakage detection.
Three Capsule Subcooling Options
Available with STD, NTS, and SUB filled capsules, which discharge condensate at 12°C, 6°C, and 24°C below steam saturation temperature, respectively.
Multiple Pipe Connection Types and Sizes
Connection sizes include 1/2", 3/4", and 1" (DN15, DN20, DN25), with BSP/NPT threaded, socket weld, butt weld, and multiple flanged connection standards available.
Carbon Steel PN40 Body
The body is made of DIN 17243 C22.8 or ASTM A105N carbon steel and has a PN40 design pressure rating.
Integrated Stainless Steel Strainer
The trap is fitted with an AISI 304 stainless steel strainer.
Installation & maintenance notes
Verify Maximum Operating Pressure and Temperature
Before installation and commissioning, verify that site conditions do not exceed the maximum operating pressure of 32 bar g for this model and that the maximum operating temperature at 32 bar g does not exceed 240°C.
FAQ
What steam system operating conditions is the IBPC32 suitable for?
The IBPC32 is a maintainable pressure-balanced thermostatic steam trap suitable for applications requiring condensate discharge based on the differential from saturated steam temperature. The standard “STD” capsule discharges condensate at 12°C below saturated steam temperature. Optional “NTS” and “SUB” capsules discharge at 6°C and 24°C below saturated steam temperature, respectively. The specific configuration must be confirmed according to the actual model and application conditions.
What is the function of the integral Spiratec sensor in the IBPC32?
The integral Spiratec sensor can be used to detect trap flooding or steam leakage. The WLS1 sensor detects both flooding and steam leakage, while the SS1 sensor is used for steam leakage detection and can be connected to an existing Spiratec monitoring system.
What sizes and connection options are available for the IBPC32?
Available sizes are 1/2 in, 3/4 in and 1 in, corresponding to DN15, DN20 and DN25. Connection options include BSP or NPT threaded connections, BS 3799 socket weld, EN 12627 butt weld, and EN 1092 PN40, ANSI B16.5 Class 150/300, JIS/KS 10K and JIS/KS 20K flanges.
What are the pressure and temperature limits of the IBPC32?
The body design rating is PN40, with a maximum allowable pressure of 50 bar g (50°C) and a maximum allowable temperature of 400°C (35 bar g). The maximum saturated steam pressure is 32 bar g, the maximum operating temperature is 240°C (32 bar g), and the minimum operating temperature is 0°C.
What should be noted during IBPC32 installation and maintenance?
During installation, the capsule should remain in the horizontal plane, with the cover at the top. Where downstream back pressure is present, a check valve is recommended at the outlet. When discharging directly to atmosphere, a silencer is recommended. Suitable isolation valves should be fitted upstream and downstream to facilitate maintenance. Available spare parts include the capsule and seat assembly, strainer screen, cover gasket set, sensor and gasket, and connector gasket. Specify the model, size and capsule type when ordering.
