Multilayer (composite) Pipes

Kisan is a leading Polish manufacturer and distributor of a modern low temperature heating system (Kisan Comfort) and multilayer pipes and fittings for internal water installation systems.

Multilayer (composite) Pipes

In 1991, like in many newly established companies, our beginnings were very modest. Kisan’s biggest capital was the idea to make multilayer pipes. It was one of the very few products that went into production almost simultaneously in Poland and in highly developed economies.

This idea turned out to be the cornerstone of our great success.

Why are KISAN composite pipes becoming so popular?

The complete answer is complex. If the key criteria for the product’s quality are considered, the pipe may be used in all types of installations. Composite pipes are not subject to the traditional constraints of the plastic piping, such as:

Working temperature:

Plastics become less resistant to inner pressure as their working temperature rises. The higher working temperature is, the more affected the strength of the pipes and the system service life is. In accordance with the conditions set forth in the relevant technical approval, KISAN composite pipe works at temperatures of up to 95°C and shows the highest temperature resistance from among all plastic pipes.

Thermal elongation:

As compared with metal pipes, plastics have a higher thermal elongation, ranging from a few to a dozen or so times, which results in the need for more frequent compensation of hot water and central heating pipes for elongation. The elongations of composite pipes are similar to those of aluminium pipes, i.e. only two times greater than those of steel pipes.

Oxygen penetration:

Diffusion (penetration) of atmospheric oxygen through the pipe wall to the system water. This phenomenon is particularly dangerous to such materials as polyethylene, crossed-linked polyethylene, polypropylene and polybutene at temperatures over 60°C. The oxygen present in the system water is the main cause of corrosion of metal elements of central heating systems. In case of plastic pipes, non-metal layers are applied onto the pipes in the production process to reduce the diffusion of oxygen. The aluminium layer used in composite pipes is a more effective method of eliminating this phenomenon, which eliminates 100% of the inflowing oxygen stream.

In addition to the product’s technical and physical parameters, other success-decisive factors also include:

  • General availability of the system in Poland,
  • Very good value for money,
  • Production based “for ages” in Poland,
  • Complete “instrumentation” of the system,
  • Training, training, training.
