Insulated tubing bundle with light steam tracing RizurPak-L and RIZURPAK-H

NPO RIZUR offers pre-insulated impulse tubes and tubing bundles RizurPak with light or heavy steam tracing.

RizurPak-L with light steam tracing is used with small diameter tubes (sampling, chemicals dosing).

RizurPak-H with heavy steam tracing is used for equipment impulse lines, process lines of analyzers, sample sections, chemicals dosing, process line of small diameter for temperature maintenance required for the media viscosity control.


Intended use and design description

RizurPak-L are individually insulated (for reduction in heat transfer) process pipes or a single process pipe that maintain temperature within the limits of 10°C … 93° C. This system of pipes with light steam tracing has an insulation layer between the heating and the process pipes for protection against overheating.

Tubing bundles RizurPak-H with heavy steam tracing provides direct contact of the process pipes with the tracing and thus ensures higher temperature maintenance.

There’re several design variants of RizurPak-L that differ in the quantity and diameter of the process pipes, as well as the diameter of the steam tracing.

RizurPak-L1 – one pre-insulated process pipe with light steam tracing.

RizurPak-L2 – two pre-insulated process pipes with light steam tracing.

Accessories and components

For connection and installation of the pre-insulated impulse tubing bundles to the pipelines, technical process and devices the following equipment can be used:

Silicone insulation

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

Input device for the tubing bundles 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 heat-shrinking 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

RIZUR-TB-DCS manufactured by NPO RIZUR can be used for temperature control in the process lines.

Thermostats

Used for temperature control in the process lines.

A set of heat shrink tape sleeves for high-temperature heating cables

The set complies with the CENELEC and GOST-R standards for operation in the hazardous areas. It's used with tracers MN and N15 or N20 of any capacity.

A set of heat shrink tape sleeves for low-temperature heating cables

The set complies with the CENELEC and GOST-R standards for operation in the hazardous areas. It can be used with tracers of any capacity.

A kit for connecting the heating cable to the power supply network

The kit consists of a cable gland and a set of heat shrink tape for installation inside the terminal box with M25 thread. It complies with CENELEC and GOST-R standards for use in hazardous areas. It can be used with tracers P, MN, and N15 or N20 of any capacity.
