Customized variants of RizurPak

Customized variants of RizurPak and other constructions designed in accordance with the Customer's technical requirements and are used for non-standard heating solutions.


Customized design variant of RizurPak can have: installed temperature sensors, thermocouples, thermoresistor, several process pipes - for example, for gas supply calibration, tracing, supply and data cables, as well as a heating tracer. Special tracing can be used for temperature maintenance of up to 315 °С (can withstand up to 540 °С), for instance CPD, MI, and resistive conductors.

Customized pre-insulated impulse tubes and tubing bundles RizurPak can be manufactured:

  • of customized length and size;

  • with housing from non-standard materials that can withstand high operating temperatures, constant bending or installation at low temperatures (Teflon®, for example PTFE, PFA, TFE, and nylon, Hastelloy, Incoloy, titanium, duplex, 6% molybdenum, stainless steel with quartz coating)

  • with different types of process pipes connection

  • with preliminary cut and fixed tube endings

  • with maximum temperature at the pipe inlet - up to 600 °С*
*For the technological processes with occasional high temperatures it’s recommended to use special constructions with a safety bumper. In such constructions the standard self-regulating tracing is separated by the safety bumper from the process pipe for protection against both high temperatures impact and freezing.

The following devices and accessories can be used for installation of pre-insulated impulse tubes and tubing bundles and their connection to the technical processes:

Silicone insulation

Black silicone insulation RTV is used for hermetization of both ends of the tubing bundle for protection against moisture penetration.

Input device for the tubing bundle RizurPak 

Input device for the tubing bundle RizurPak provides waterproof insulation in the place of tubing bundle RizurPak entering the enclosure, for example, through a wall. The input device for the tubing bundle RizurPak consists of a set of rings and a heatshrinking cap for tubing bundle insulation.

Heat shrink tape sleeve

Heat shrink tape sleeves ensure insulation of the ending part of RizurPak that protects the system against climatic factors impact. The material used is thermally stabilized modified polyolefin. It’s recommended to use heat shrink tape sleeves for all the open endings of the tubing bundle. This sealing method provides the best protection against climatic factors impact.

Repair kit for the housing

The repair kit for the housing is used for sealing the connections in the tubing bundle or for the elongation of the insulation layer and the housing that protects the system against climatic factors in cases when during installation the cut piece was too long or if there’s a need to join two tubing bundle cuts. The materials in the kit are used for any repairs of tubing on-site. The repair kit is necessary when mounting an additional thermostat for temperature control of the process tubing. Each kit has a thermal insulation material, fiberglass tape, and a self-sealing patch.

Thermoregulators

Temperature control in process pipes is provided by the thermoregulators of RIZUR-TB-DCS series, manufactured by NPO RIZUR.

Non-standard materials and tube sizes

RizurPak system can be manufactured on the base of tubes of non-standard sizes and from the non-standard materials in accordance with your technical requirements, including:

  • Different versions of Teflon®, for instance PTFE, PFA, TFE, and nylon.

  • Hastelloy,

  • Incoloy,

  • titanium,

  • duplex,

  • 6% molybdenum,

  • tubes cleaned for oxygen supply,

  • stainless steel tubes with quartz coating

Multi-component bundles

Complex structure can contain the factory-installed temperature sensors (for instance RTD, thermocouple, temperature-sensitive resistor), several process tubes (for instance data and supply cables), as well as a heat tracing.

High-temperature heaters

For maintenance of temperature of up to 315°С (can withstand the temperature of up to 540°С) it’s possible to use  specialized tracers, for example CPD, MI, and resistive conductors.

Housing materials for different applications

NPO RIZUR offers housing versions from different type of materials that can withstand high operating temperatures, constant bending or installation at low temperatures. Materials for outdoor applications are: polyurethane, polypropylene or PVC, while versions for indoor applications are: polyethylene or stainless steel screening.

Constructions enhancing operational characteristics

For the technological processes with occasional high temperatures it’s recommended to use special constructions with a safety bumper. In such constructions the standard self-regulating tracing is separated by the safety bumper from the process pipe for protection against both high temperatures impact and freezing.
