These systems are available in a number of sizes and are supplied for many applications. Many years of research has led to a wide range of systems, which are reliable and easy to install.
Our comprehensive product line covers most needs – speciality components are available when required.
It is Logstor`s mission to create and manufacture pre-insulated piping products which will provide trouble free service over many years. Logstor has been ISO 9001 registered since 1992.
The Logstor District Heating system is used for media at a temperature range between 0°C and 140°C – typical media are district heating. The system can also be used for other types of fluid media. The system consists of polyurethane insulation with unique properties which ensure low operational expenditure, enclosed in high density polyethylene jackets.
Carrier Pipes
District heating pipes are available as straight or flexible pipes. The material of straight carrier pipes is Steel - St. 37.0 BW, PEX and Copper. Flexible pipes are available with three types of carrier pipes: Steel-Flex, PEX and Copper.
