Pre-insulated Pipeline Systems - Introduction
The Company IZO Ltd. Bořetice produces pre-insulated pipeline systems, which include in addition to pipeline itself also pipe bends, branches, armatures, compensators, fixed points and other accessory parts including a monitoring system. This assortment enables to solve economically distribution systems of heat and coldness, eventually of other mediums in complete finish; it means underground channelless bedding, but also surface distribution systems.
Pre-insulated systems produced in a standard version for mediums from -200 °C up to +140 °C comply with standards valid for this kind of products, i.e. ČSN - EN 253, 448, 488 and 489.
The basic range of channelless version enables to leave out labour-intensive and expensive building up of concrete channels. The surface version in the spiro-pipeline outstands similarly with a very qualitative insulation, high strength and thereby with resistance to damage.
Basic properties and advantages in comparison with conventionally performed energetic distribution systems in channels:
|1. ||Considerably reduced costs on earth works (narrower profile, smaller depth)|
|2. ||Noticeable shortening of construction time|
|3. ||Reducing of energy losses due to qualitative insulation|
|4. ||Environment protection through the use of cfc-free PUR systems|
|5. ||Life time at least 30 years|
|6. ||Range of use according to temperature load 140, 180 up to 300 °C|
|7. ||Possibility to select insulation thickness|
|8. ||Maximum prefabrication and simplification of installation works|
|9. ||Reduced transportation charges|
|10. ||Reduced operating costs and maintenance expenses|
|11. ||Easy check and fault localization due to installation of monitoring system|
|12. ||Completeness of components offer of our Company simplifies customers realization intents|
|13. ||Short delivery terms, operational suitability|
IZO Ltd. Bořetice is a purely Czech company engaging in own production and realization of pre-insulated pipeline systems.
Pre-insulated pipelines for channelless bedding are produced in two basic versions:
I. Compact system – where the medium-conducting pipeline, insulation and protection pipe build up a compact unit that is limited in dilatation movement by friction in sand bedding. This system consists of three layers for the temperature range from -200 °C up to +140 °C of continual temperature loading.

II. Sliding system – the medium-conducting pipeline is located in a sliding way in mineral wool insulation, which builds up one unit with polyurethane and a protection pipe. The dilatation movement is to be compensated by means of axial, eventually jointed compensators. This system is four-layer one for temperature range from -200 °C up to +180 °C and from -200 °C up to +210, 240, 270 and 300 °C. The insulation is solved in such a way that the temperature on the transition of insulation layers reaches at most +120 °C.
