INSTALL ENGINEERING SV. Ltd produces the most advanced and modern preinsulated piping systems from glassfiber polypropelene (PPR-GF and PPR-CT-GF) in Eastern Europe. We are the only company on the market which produces piping system specialized for mineral water which can transfer water up to 90oС .


With more than 20 years of proven performance, PPR pipes have been used around the world for plumbing, mechanical and industrial applications. Pipes made from glass fiber PPR do not corrode, rust, or scale. Furthermore, their lightweight components are easily joined via heat fusion for permanent, leak-free joints.


PPR-CT-GF is the newest generation polypropylene and has better mechanical properties than PPR-GF. The improved mechanical characteristics come from the crystalline structure of the raw material, giving the material the ability to perform at higher pressures and at elevated temperatures.

The main advantage of these hot mineral water pipes over the rest of the polypropylene, polyethylene and polybutylene pipes is the low value of the linear elongation coefficient – it is 400% lower than that of other pipes and is easily positioned along the pipe route. With 400% less elongation, there is 4 times less compensators needed, thus resulting in a significant reduction in the cost of the pipe and easier installation.



Install Engineering SV Ltd. manufactures its plastic pipes according to the international standard for plastics piping systems for water supply under pressure EN 12201-2. All company manufactured products are covered by certificates of conformity in accordance to their respective standards,issued by authorized body, according to which they are designed for water supply networks.

Main features of polyethylene pipes
  • Resistant to abrasion, chemical breakdown and corrosion
  • Non-toxic - No hazardous waste
  • Lightweight
  • Flexible and durable
  • High impact strength
  • Recyclable
  • Smooth inner surface
  • Cost effective
  • Long life

    Polyethylene PE 100 is flexible and highly resistant to vibration material. Due to its flexibility, the route of the pipeline can simply follow the pattern of ground, so there is no need of many additional components.



    INSTALL ENGINEERING’s high quality pre-insulated pipes are based on eco-friendly production process, complying with the international standards for this type of production.

    The insulation layer is consisted of ecologically clean polyurethane foam and isocyanate foam without Freon. This type of insulation has the lowest thermal conductivity: λ=0.018-0.029 W/m.K, which ensures up to 70% less heat losses.

    Advantages of preinsulated pipes

    The jacket pipe can be produced either from high-density polyethylene (HDPE) for underground installation, which complies with the international standards, or from spiral folded sheer iron for above-ground installation. The forces of adhesion between the polyurethane foam, the service pipe and the jacket pipe allow the forming of a strong bond. In the same time, this combination ensures the long-term operation of the installation.



    The polyurethane insulation shells for pipelines are designed mainly for district heating pipes and projects.

    Advantages of polyurethane insulating shells

    The polyurethane, from which the shells are made, is complying with all the standards and certificates for manufacturing of this type of products.

    The insulation shells are significantly decreasing the heat losses along the pipeline, which leads to minimized extra costs, involved in heating the pipeline and the working fluid. These products are also applicable in the industrial sector.

    The insulation shells can be produced either in set with the corresponding pipes, or upon client request. The desired size and thickness of the polyurethane insulation should be specified.
