Pre-insulated version: ensures seamless integration in existing insulation structures. Diverse shapes and types: available as bends, T-pieces, transition pieces and more, suitable for different pipe configurations. High insulation values: minimise heat losses in the district heating network effectively. Easy assembly: enables fast and efficient installation, which saves time and costs. Durability : made from robust materials, which ensure a long service life. Fittings are essential components in district heating systems that are pre-insulated at the factory, enabling quick and reliable installation. To cover a wide range of pipe connections, they are available in various forms such as T-pieces, parallel branches, or reducers. ISOPLUS bends are available in 90°, 45°, or custom angles upon request. These fittings ensure continuous thermal insulation, thus minimizing heat loss in the system. T-branch Parallel branch Drain/venting branch 90° Reducer Twin branch Y-pipeThe T-branch enables reliable branching of district heating pipes to distribute heat efficiently. The parallel branch ensures reliable branching parallel with the main transport line, ideal for uniform heat distribution in many areas. This branch facilitates secure draining and venting of district heating systems in order to optimise maintenance and operation. The reducer enables a seamless transition between different pipe diameters and ensures flexible adaptation in the district heating system. The twin branch enables a transition from a double pipe in the passage pipe to two single pipes in the outlet pipe. Ensuring the optimum collaboration throughout our pipe system, the Y-pipe casing enables the smooth transition from single pipes to twin pipe networks and vice-versa.
Fittings especially for the subsequent insulation of rigid and flexible pipe systems Weldable and shrinkable HDPE fittings Factory-fitted for on-site requirements Installation fittings are made of uncross-linked and therefore weldable polyethylene and can be used as assembly joints and retrofit fittings. These are all insulated with rigid polyurethane foam, in the same way as the other system components. In general, installation fittings are installed by certified ISOPLUS personnel. Some systems, such as those for flexible pipes, are so easy to handle that they can be installed by the installer. Please note : Assembly joints/installation fittings do not meet the requirements and guidelines of EN 253 and should therefore be avoided wherever possible in rigid pipe systems. Installation bends Installation branch Installation accessories Flexible pipe systems connection technology ISOPLUS installation bends are made of shrinkable PEHD according to the radius and diameter of the fitting and the insulation series of the pipe system. Operating conditions: suitable for all pipe networks with increased operating conditions and soil conditions such as groundwater and pressing water. Diameter: from Da 90 mm to Da 1200 mm Delivery length: Dependent on dimensions, min. 450 mm per leg If subsequent building connections must be made, installation branches can also be used in absolutely exceptional cases. This requires making a carrier pipe branch, e.g. by tapping. The PEHD branch is cut in the axial direction, folded over the carrier pipe and then welded using the PEHD extruder process. Installation branches with diameter ≥ 280 mm must be avoided. The scope of supply includes a special through-joint with outlet sockets. The main transport line consists of a long shrinkable connection joint in which the outlet socket made of non-shrinkable PEHD casing pipe is welded-in in the factory. The shrinkable PEHD installation bend, reduced at one end, is mounted onto this socket. The diameter of the outlet socket and the installation bend depend on the tapping method used. To ensure the necessary insulation thickness is achieved, it may be necessary for the installation bend to be supplied with a diameter that is several sizes larger. It is therefore absolutely necessary that, before tapping, ISOPLUS is notified of the following details by way of a true-to-scale drawing: tapping method or system, nominal diameter of through pipe and outlet, vertical centre-to-centre spacing or centre-to-centre distance between carrier through pipe and outlet, outlet type (different types of outlets possible on request), uninsulated or shell-free length of through-pipe (max. 400 mm) and outlet (max. 250 mm). Without these parameters, PEHD installation branches will not be delivered or made! They include crimping sleeves, wire, spacers, mastic adhesive tape, welding plugs, venting plugs and shrink collars, which are needed for the connection technique and subsequent joint installation. We offer you a selection of high-quality products for fast and secure installation and durable connection of your flexible pipe systems: Fittings: these include all important joints and casing joints necessary for the installation and operation of PEX pipe systems. Casing joint: these joints ensure reliable and tight connection between two lengths of pipe. Connection coupling: available as press or clamp coupling, they ensure secure connection of pipes to different systems and equipment. Reducer coupler : these couplings, which are also available as press or clamp variants, enable the transition between pipes with different diameters. Connection angle 90°: this angle connector enables secure and precise connection of pipes at right-angles. T-piece: available as press or clamp couplings, this connection element is used to split or merge pipelines. Flexible joint: this flexible connection element enables simple connection of pipes, even in confined or difficult installation situations. Please contact your ISOPLUS sales contact directly to find out whether it is available in your country. Y-shaped heat-shrinkable joint: a special Y-shaped connection coupler, which creates a tight connection by shrinking. Please contact your ISOPLUS sales contact directly to find out whether it is available in your country. Sandwich bends and branches 90°: are high-quality fittings or insulation half-shells made of glass reinforced plastic (GRP). These components are intended for self-installation or installation by an installer. They can be insulated subsequently and thus off an optimum solution for the secure and durable connection of pipelines in bends and branches, even under difficult conditions.

Am 05. November 2024 wurde die neue Heiz-
zentrale für Fernwärme im Schloss Hohentübin-
gen eingeweiht. Bis dahin war es, auch wenn die
Länge der Trasse das so nicht vermuten lässt, ein
nicht ganz einfaches Projekt für die Verantwort-
lichen.
Was waren die größten Herausforderungen?
- Trassenführung durch enge Gassen
- Steiler Hang zum Schloss hinauf
- Fledermäuse im Keller des Schlosses
- Einbeziehung von Denkmalschutz, Naturschutz,
Arbeitsschutz und Artenschutz
Im Herbst 2023 begannen die Arbeiten - parallel
oben am Schloss und unten in der Altstadt.
FAKTEN
Kunde
Trommler Rohrleitungsbau GmbH
Projektlaufzeit (ISOPLUS)
14 Monate
Länge Trasse
ca. 1,5 km
Moderne Wärme für Schloss Hohentübingen
Anschluss an das Fernwärmenetz
Land
Deutschland
Bauzeit
14 Monate
Wärmelieferung pro Jahr
ca. 1.000.000 KWh
ROHRSYSTEM
• Kunststoffmantelrohre und Formteile
DN 32 bis DN 200
• Doppelte Dämmstärke
• Leckageüberwachung mit
Brandes-System
200 t CO2 pro Jahr eingespart –
ein steiler Weg, der sich lohnt!
Die Wärmeleitung verläuft durch unwegsames
Gelände vom Fuß des Schlossbergs steil hinauf
zur Nord-Bastion.
Wir machen gemeinsam mit Partnern die Ener-
giewende möglich.
Weitere Informationen zum Projekt erfahren Sie
im Blog der Stadtwerke Tübingen.
Durch die dicken Schlossmauern hindurch
wurde die Leitung in einen Keller unter dem
Rittersaal geführt. Da dort eine Fledermaus-
kolonie residiert, die nicht gestört werden
darf, waren die Arbeiten nur in dem Zeitraum
möglich, als die Tiere in ihr Winterquartier
wechselten.
Schlussendlich wurden alle Herausforderungen
gelöst und die Anlage konnte wie geplant in
Betrieb gehen. Sie wird zukünftig jährlich rund
200 Tonnen CO2 einsparen.
