Overview of the most important district heating pipe DN specifications

District heating supplies thermal energy and hot water from various plants, obtained from different processes – from waste heat, waste, biomass and more. District heating is becoming increasingly popular and is now widely used. But which district heating piping system should you choose? And which dimensions are suitable and available? Here you can get a quick overview of the piping you are looking for: the district heating pipe DN diameters from BRUGG Pipes Solutions on one page. 

FLEXSTAR UNO available in DN 20, DN 25, DN 32, DN 40 and DN 50

This low-temperature system is pre-insulated, highly flexible and extremely stable. If you are looking for an efficient medium pipe, FLEXSTAR UNO offers a secure connection with first-class insulation. Manufactured in accordance with EN 15632-2, the system meets the high requirements of ISO 9001, ISO 45001 and ISO 14001. In other words: Swiss quality at the highest level.

The efficient FLEXSTAR UNO local network and heat pump pipe is available in sizes DN 20, DN 25, DN 32, DN 40 and DN 50. FLEXSTAR is also available in a DUO version with two medium pipes in other nominal sizes.

CALPEX PUR-KING is available in DN 20, DN 25, DN 32, DN 40, DN 50, DN 100, among others

Admittedly, one should be wary of superlatives, but CALPEX PUR-KING deserves an exception. Its thermal conductivity of only λ 0.0199 W/m*K is unique. It is significantly lower than the previous lower limit of 0.0210 W/m*K. This makes CALPEX PUR-KING an energy-saving champion. This is made possible by an innovative production process. Many users are delighted not only by the efficiency of this pipe, but also by the wide range of dimensions available. 

CALPEX PUR-KING is available in nominal diameters DN 20, DN 25, DN 32, DN 40, DN 50, DN 65, DN 75, DN 90, DN 100, DN 110 and DN 130. CALPEX PUR-KING is also available in a DUO version with two media pipes in other nominal diameters.

CASAFLEX heat pipe is available in DN 20, DN 25, DN 32, DN 40, DN 50, DN 100

State-of-the-art, thermally insulated and self-compensating – with its corrugated pipe and high-quality PIR thermal insulation, CASAFLEX heat pipe is designed for 16/25 bar (operating pressure) at 150 °C (operating temperature). However, peak temperatures of up to 180 °C are also possible in exceptional cases. This makes CASAFLEX efficient and safe, quick and easy to install, as well as sustainable and economical in the long term.   

All available nominal diameters of CASAFLEX are DN 20, DN 25, DN 32, DN 40, DN 50, DN 65, DN 80 and DN 100. CASAFLEX is also available in a DUO version with two media pipes in other nominal diameters.

FLEXWELL-FHK is available in DN 25, DN 32, DN 50, DN 100 and other nominal sizes

The FLEXWELL-FHK district heating cable impresses with its jacket pipe, which is 100% diffusion-tight, effectively insulates heat and remains energy-efficient with absolute operational reliability even under extreme conditions. The reason for this is the PUR foam, which protects the pipe system from moisture and significantly increases its service life compared to conventional pipes.    

Find out more about FLEXWELL-FHK and its available nominal diameters DN 25, DN 32, DN 50, DN 65, DN 80, DN 100, DN 125 and DN 150 here.

PREMANT – available in DN 20, DN 25, DN 32, DN 40, DN 50, DN 100, among others

It is rigid and combines excellent properties with exceptional versatility. PREMANT is suitable for transporting both district heating and industrial fluids. Above ground, underground – wherever the route takes it, PREMANT delivers impressive performance and energy efficiency. PREMANT enables environmentally friendly and sustainable energy supply. 

The versatility of PREMANT is also reflected in the wide range of pipe diameters available: DN 20, DN 25, DN 32, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300, DN 350, DN 400, DN 450, DN 500, DN 600, DN 700 and DN 800. It is also available in a DUO version with two media pipes in nominal widths from DN 20 to DN 250.
