Insulated tubing bundle with an electric tracing RIZURPAK-E

RIZURPAK-E systems are designed for protection against freezing, maintenance of required temperature in a small range or for maintenance of the required media viscosity. This system is the best solution for temperature maintenance along the whole length of impulse lines and pipelines.
RIZURPAK-E tubing bundles are recommended for use in cases when it's impossible to use steam tracing or when there's a possibility that steam supply will be cut off if the required equipment will be  turned off.

Intended use and design description

RIZURPAK-E systems are designed for protection against freezing, maintenance of required temperature in a small range or for maintenance of the required media viscosity. This system is the best solution for temperature maintenance along the whole length of impulse lines and pipelines. In this design variant self-regulating heating cable is used as a heating source.
RIZURPAK-E ensures temperature maintenance in the process tubing within the range of 10°С to 121°С because the self-regulating heating cable reduces heat generation when the process tubing heats up.
It’s recommended to use RIZURPAK-E when it’s necessary to maintain the temperature in the range of 10°С to 121°С as a self-regulating system will reduce heat generation when the process tubing heats up. In order to ensure the temperature maintenance, it’s also necessary to use a thermoregulator.

Design variants of RIZURPAK-Е (depending on the tracing used)

1. Low-temperature
In this design variant low-temperature self-regulating heating cable BTV is used as a heating element. BTV cable can withstand medium temperature of up to 65°C (constantly) and up to 85°C (temporally). Insulated tubing bundles RIZURPAK-E of the low-temperature design variant is mainly used for protection against freezing or for maintaining temperatures of up to 37°C.
2. High-temperature
In this design variant, high-temperature self-regulating heating cable XTV is used as a heating element. XTV cable can withstand medium temperature of up to 121°C (constantly) and up to 250°C (temporally). Insulated high-temperature tubing bundle RIZURPAK-E is mainly used for medium temperature maintenance up to 121°C. For maintenance of higher temperature, it’s possible to use two electric heating tracers in one bundle. This design variant is used for protection against freezing in technical processes and operating conditions that anticipate temporal temperature rise during, for example, steam operation.
3. Customized
This design variant of RIIZURPAK is used for high-temperature processes as well as for maintenance of temperatures above 121°С. In this design variant it’s possible to use two electric heating tracers in one bundle, while self-limiting or resistive cables can be used as a heat tracing. This design variant of RIZURPAK-E is designed for process temperatures of up to 800° and so its parameters are calculated individually in accordance with the process conditions.

Standard parameters

Each graph shows standard parameters with summer/winter ambient conditions divided. Each graph is divided at the 16°С point to designate seasonal difference. In the winter period, when the temperature is below 16°С, the wind is expected to be about 40 km/h, and in summer the temperature is above 16°С and the wind is about 16 km/h. For protection against freezing consider 10°С the minimal permissible temperature of the process pipe. This will provide sufficient reliability.
