Pre-insulated pipes - characteristics

Pre-insulated pipes are made of an external casing, an insulated layer (usually made of polyethylene) and internal/transmission pipes (usually made of PE-Xa, i.e. cross-linked polyethylene). This construction provides incredible strength parameters, great flexibility and durability. Pre-insulated pipelines also offer excellent thermal insulation properties, thanks to which it is possible to reduce heat losses by up to 50%.

Preinsulated pipelines are used in various types of systems. They can also be used in low-parameter heating networks. They guarantee reliable transport of liquids in heating, cooling and sanitary installations. The network is installed efficiently, even in very difficult conditions on the construction site. Preinsulated pipes will work well both in domestic conditions and in the case of large facilities, e.g. service or industrial.

Basic advantages of pre-insulated pipes

Pre-insulated pipes have a number of advantages that make them extremely popular among professional installers. These include:

very high mechanical strength thanks to the use of an external jacket,
impact strength over a wide temperature range,
flexibility,
an insulating layer that reduces heat loss, with minimal water absorption and water vapour permeability,
quick and easy installation (can be laid directly in the ground).
