Definition: What is a pipe system?

A pipe system is defined as the complete network of interconnected pipework, including all fittings and connections, along with all related components. The system is designed based on the principle of modularity. This means that the individual components have the flexibility to be combined and assembled in different ways, resulting in a wide range of possibilities. Even highly complex designs can be implemented in a relatively straightforward manner. Self-contained pipe systems then form the basis for supplying and transporting media such as water, waste water, condensate, steam, gases and chemicals.

The range of a system depends on the respective construction project. No matter the distance, whether a short distance for local heating or within industrial plants or a long distance for extensive district heating networks, any transport task can be easily accomplished with the appropriate pipe model. Long-distance pipelines, which are specifically engineered for transporting media across vast distances, can be readily adapted to accommodate a wide variety of terrain conditions. The routes on which the trenches for laying the pipes later run can be found in landscapes that differ greatly from each other. Challenging ground conditions, such as wetlands, subsidence, river or road crossings, compacted soil beneath concrete surfaces or soils with high sand content, are now no longer an obstacle to the stable and safe installation of the systems. 

The choice between a rigid or flexible pipe system is determined by various factors, including the intended use, the medium being transported and additional circumstances such as the respective ground conditions. This property is also one of the main distinguishing criteria for the various types of pipe systems. Flexible pipe systems can be bent to a specific extent and used to implement small routing angles without the need for additional components. The material composition of the inner and outer pipe can be adjusted to control the degree of flexibility and stiffness of the pipes. The next step is to determine the dimensions, installation lengths and accessories, as well as the connection points.

Different applications – different pipe systems

In each specific case, the type of pipe is always determined by the medium flowing through the pipe system. In the context of water and waste water pipes, the following question arises as to their function: are they primarily used for heating and cooling or simply for transportation (or discharge)? Examples of the latter include the provision of drinking water using aluminium composite pipes, the discharge of service water in sanitary facilities and the use of pipe systems for the return flow into the sewer system. In addition to pipes for hot, cold, service and waste water, various other media also flow through pipe systems. Here we distinguish between gas pipes, oil pipes, pipes for industrial products and pressurised pipes, among others. To ensure we maintain an overview of all the specifications, including the material properties, media, dimensions and so on, we organise our range into various primary categories. These are geared toward the respective application areas.

Local and district heating – Flexible, pre-insulated pipe systems with excellent insulating properties are usually installed in this area. However, the large-scale commercial expansion of district heating networks initially began with the use of rigid steel pipes. Nevertheless, the tide turned with the advent of technological advancements in plant engineering and numerous new research findings. In recent decades, plastic pipes have increasingly been chosen for use in the build-out of the supply infrastructure. In many cases, this flexible alternative achieves even better measured values for insulation performance. Still, there are certain advantages to using rigid pipe systems with a stainless steel or other solid metal medium pipe compared to pipework made of PE (polyethylene) plastic. Therefore, it always remains a case-by-case decision as to which pipe system is ultimately the better choice in a direct comparison.­­

Hot and cold water – Here we only offer flexible, continuous systems. They also have distinct property profiles: Some are certified for drinking water, others are designed with oxygen barriers and still others have integrated frost protection or heating tape. What is important depends entirely on the intended use and the associated requirements. Is the focus on the impeccable quality of the supplied water or the temperature of the medium? If the latter is the case, then the system is equipped with high-quality insulation made of polyurethane (PUR).

Industrial plants – Ensuring absolute safety is crucial when it comes to pipe systems designed for industrial processes. Such systems are all uncompromisingly reliable when it comes to conveying media that are in some cases potentially hazardous to the environment. BRUGG Pipes offers single-walled and double-walled, rigid and flexible pipe systems. A wide range of safety precautions are also taken to ensure the well-being of employees and the smooth operation of the plant, including the monitoring of overpressure and underpressure leaks. This is because the pipes often transport liquids and gases that are environmentally hazardous and toxic.

Special safety mechanisms are also required for pipe systems for petrol stations and tank systems: The pipe systems designed for the transportation of gas, oil and other fuels, as well as highly flammable media, are equipped with effective corrosion protection and are further safeguarded by highly sensitive monitoring technology. These special precautions, combined with weld-free design, make such systems extremely safe. For safety reasons, welding work is not performed during installation due to the presence of highly flammable media. Instead, a flameless connection technology is available specifically for these pipe systems.

Cryogenic applications – These pipe systems are both flexible and safe due to the incorporation of bendable corrugated stainless steel pipes. Additionally, they are vacuum-insulated and pre-assembled. The enhanced insulation, that is, the combination of vacuum and insulation, prevents the transfer of heat to the medium. This is important because cryogenic, liquefied gases are transported in the special pipes at temperatures as extremely low as -200 degrees Celsius. Depending on the application requirements, it is possible to implement the flow and return in just one pipeline. In order to optimise the implementation of the order, there is also flexibility in deciding whether the BRUGG Pipes line should be installed underground or above ground. The ready-to-use promise of our pipework for cryogenic media is completely independent of flow direction and installation, as all pipe systems in this category are pre-assembled in the factory. This involves cutting the pipes to the correct length, inspecting and welding the connections and establishing a vacuum. As everything is ready, installation can start immediately after delivery to the construction site.

Bioflex fermenter heating – Our BIOFLEX pipework and its accessories are specifically engineered to heat biogas fermenters. The system can be connected to either the outer or inner wall of the digester and provides the plant with direct heat transfer during the conversion of biomass into biogas. The heating system provides perfect environmental conditions for the microorganisms. Only on this basis is it possible to efficiently produce biogas, which is then burnt and converted into electricity and thermal energy.

  • The advantages of flexible pipework

    BRUGG Pipes offers flexible pipework in all product categories and thus offers versatile system solutions for every application – whether for district heating, water systems (hot and cold water or drinking water and waste water), industrial plants and cryogenic applications or oil and gas transportation to petrol stations. We manufacture our flexible pipework using high-quality stainless steel or innovative plastics. In addition to their unique material properties, the flexible models offer numerous advantages: Both material groups offer pipework that is durable and resistant to heat and corrosion, ensuring the safe and efficient transportation of liquids, gases and heat. The diameters of the medium pipe and outer pipe may vary depending on requirements and application.

    The flexibility and therefore the minimum bending radius also depend on the material and the specific composition. We would be happy to plan, determine and measure the route for you and find the optimum pipe system based on the individual project specifications. Greater flexibility allows for smaller bending radii to be achieved, leading to more efficient installation. Compared to the rigid version, the installation and connection of flexible pipes is generally much simpler. The ability to bend these pipes with smaller radii also facilitates their integration into existing systems. We also modify the lengths of the pipes and accompanying accessories to align with the planned design. For complete planning freedom and particularly complex construction projects, our customers can of course also order custom-made products. However, this is rarely necessary. Flexible pipework typically allows for a tailored solution in nearly all cases, whether a short section, a lengthy connecting pipe or a branching system is involved.

    In summary, flexible pipework offers numerous advantages: It is highly adaptable and resistant to both chemicals and mechanical loads while also featuring a long service life. Due to their flexibility, these materials are well suited for complex industrial applications and other challenging tasks such as district heating and cooling as well as transportation of water. Flexible pipework is a highly reliable and efficient solution, thanks to the use of tried and tested materials. For example, the majority of pipes in our portfolio offer self-compensating properties, exceptional thermal conductivity and fast, hassle-free installation, in part without welding.

A bestseller: our flexible heating pipes

As previously mentioned, both rigid and flexible pipe systems have their own unique qualities and characteristics. However, flexible models are now favoured due to their numerous benefits, particularly for heating, sanitary and service water pipes. One notable advantage of flexible heating pipes is that they can be bent to a certain degree in all directions, allowing for compact installation. Irrespective of the specific location or the conditions of the route, we offer our factory-prefabricated pipework in long lengths. Installing new heating pipes in this combination is typically a straightforward process. This is because flexible pipes in long lengths can ideally be installed in one piece – or at least help to significantly reduce the number of connection points. This not only simplifies installation but also significantly accelerates the assembly process. If the pipework is only available in short dimensions, then it will need to be joined individually at each connection point. 

Are you interested in converting your heating system and hot water supply so it can be connected to the local or district heating network? Flexible local heating pipes are also frequently used in this segment. Particularly in these applications, it is advantageous that flexible pipe systems are often less prone to corrosion and more resilient in the presence of significant temperature fluctuations and moisture. But the following applies to all heating pipes, whether flexible or rigid, made of stainless steel or plastic: the pipe insulation is crucial. It determines whether the heating pipe ensures effective heat transport. Therefore, the determining factor for optimal heating pipes lies not in the material of the pipework itself, but rather in the choice of insulation material. We generally use PUR rigid foam for this purpose. Polyurethane is a plastic that has outstanding insulating properties and is also heat and weather resistant. By leveraging our unique process technology, we achieved unprecedented thermal conductivity values, resulting in a significant increase in energy efficiency.

Our product portfolio includes various models of flexible heating pipes, sorted according to the above-mentioned categories – such as CALPEX PUR-KING or CASAFLEX in the local and district heating segment and FLEXSTAR, which is specifically designed to be connected to heat pumps. This gives our customers options and allows them to customise the pipe system to the specific requirements of their construction project.

  • What really matters for underground lines for heating systems

    Let’s focus on the topic of underground heating pipes used as supply lines. Generally speaking, the term underground lines refers to heating pipes that are installed underground, and such pipes can be used in applications such as local or district heating systems. Underground lines play a crucial role in heating systems, as they are essential for ensuring safe and efficient supply operations. Repairing or replacing heating pipes can be a time-consuming and expensive process, particularly when they run underground over a long distance. High-quality underground lines for heating systems therefore pay for themselves.

  • The two essential characteristics of long-distance lines

    In addition to corrosion resistance, which ensures a long service life for the line, insulation is particularly important. Insulation is responsible for ensuring that consumers really do heat efficiently – that is, effectively and economically. For example, if the lambda value of the capillary is exceptionally low, this indicates an excellent insulating effect. The insulation material used traps heat, with only a small amount of thermal energy escaping into the environment.

  • The advantages of flexible BRUGG Pipes underground pipes

    What is expansion all about? The term expansion refers to the phenomenon of underground lines expanding in response to temperature fluctuations:
    Pipes undergo expansion when they are heated due to temperature changes in the fluid they transport, and they contract when they cool down. Expansion compensators are used in conjunction with rigid pipes to counteract the change in length of the pipes and to prevent this effect from leading to stress and damage. This is not necessary with the flexible BRUGG Pipes pipework, as the pipe construction can flexibly absorb the change in length.

    In addition, the innovative BRUGG Pipes pipe systems offer you complete planning freedom: We offer the vast majority of underground lines in different versions, such as double pipes, which enables the installation of a return pipe directly through the same heating system. This allows for narrower trenches, resulting in significantly reduced labour requirements, in addition to more flexibility in the route. The large selection of accessories, tools and connections (fittings) enable customised adaptations to the terrain and construction project, such as complex routing, small-angled branches and weld-free connections (including connections to heat pumps). Our underground lines are equipped with high-quality connecting elements that have been optimized for quick assembly.

Planning follows selection

As can be clearly seen, our products differ greatly according to system. Once all the information regarding the construction project is available, it is crucial to define the primary objective, the respective requirements, the proposed solutions and other relevant details. As a full-service pipe system supplier, we offer a wide range of solutions to help you quickly find the right pipe solution based on the specific property profile and different thicknesses. Once the final decision has been made in favour of the optimal primary component, the detailed planning work for the project begins. Based on static calculations as well as planning and installation drawings, it is possible to precisely determine the route and identify the components needed in addition to the pipework itself. All our product ranges come with a wide range of accessories. This ensures the optimal execution of the order, as all possible solutions for the implementation of the pipe system are feasible. What does that mean specifically?

The connection points to other pipework and the corresponding fittings are located directly at the ends of the pipeline. In plant engineering, media are diverted using fittings, which are found not only on pipework but also on boilers and tanks for liquids and gases. Fittings are indispensable for establishing connections with other components. In this context, you usually have the choice between screw fittings, push-in fittings and press fittings. As their names suggest, they differ in terms of the connection technology and sometimes also in the material and component types that they connect. In order to properly maintain pipe systems, it is necessary to have valves that can discharge liquids or gases from the pipes. A pump is frequently used to supply the required driving force at the return flow point of the media. Due to its excellent thermal conductivity and corrosion resistance, the copper alloy brass continues to be a highly suitable material for pumping devices to this day.
