Our range of supports and fixings for hydraulic networks
What is a hydraulic network?
A hydraulic network is a fluid distribution system, mainly water, used in HVAC (Heating, Ventilation, and Air Conditioning) installations to transport thermal energy throughout a building. This network forms the backbone of heating and cooling systems, allowing the circulation of heat transfer fluids between production equipment and points of use.
There are several types of hydraulic networks in HVAC: heating networks, cooling networks, domestic hot water networks, and drainage networks.

Rails & accessories for hydraulic networks
Our STRUT fixing rails are designed to offer a reliable and adaptable support solution for your hydraulic networks. Made of electro-galvanized steel (EZ), they are robust and resistant to corrosion, guaranteeing a long service life even in challenging environments. Our range of perforated or notched rails comes in different versions: single or double, of different lengths, widths, heights, and thicknesses to meet your needs for supporting light to heavy loads.
- Standard rails: Available in several sizes, they adapt to a wide range of hydraulic applications and allow stable pipe fixing.
- Reinforced rails: Designed to support heavier loads, ideal for industrial hydraulic installations.
- Mounting accessories: We offer various accessories such as connectors and reinforced brackets, wall supports, double consoles, and console reinforcements dedicated to heavy loads.

Clamps dedicated to hydraulic networks
We offer a varied range of clamps specially designed for hydraulic networks, ensuring optimal fixing and vibration reduction:
- Heavy clamps: Ideal for industrial installations requiring rigid and solid fixing, these clamps are made of high-strength steel for maximum support of large-caliber pipes.
- Insulated clamps (PIRFLAM/PIRFLEX): for supporting insulated pipes (hot, cold, or mixed water). The installation of PIRFLAM or PIRFLEX insulating clamps prevents the appearance of thermal bridges and condensation at pipe support points. The integrated coating ensures perfect continuity of the vapor barrier of insulation systems.
- Clamp with EPDM band (ethylene-propylene-diene monomer): This material is known for its resistance to water, weather, and temperature variations, making it ideal for outdoor applications or demanding environments.
All our clamps guarantee stable and durable fixing while protecting pipes from mechanical and thermal stresses. Their design allows for quick and efficient installation for professionals.

Suspension system for hydraulic networks
The suspension and support of pipes must be reliably designed to address the constraints related to the thermal expansion of the network, caused by temperature variations. Our range includes various suspension elements adapted to the most demanding environments:
- Expansion slider: plate made of electro-galvanized steel (EZ), adapted for mounting on rails, the use of the slider allows for handling network expansion constraints due to temperature variations.
- Adjustable fixed points: the fixed point is used for supporting rising columns. In addition to dedicated clamps, it allows for taking up heavy loads. It is also used to guide expansion in conjunction with sliders.
- Adjustable stirrups and supports: Allow precise adjustment and easy installation, they adapt to pipes of different sizes and configurations.
Our systems are designed to easily integrate large-scale structures and ensure optimal load distribution. The design of our products facilitates their installation and reduces assembly time for professionals.

Your frequently asked questions about hydraulic network support
Several essential characteristics should be considered when selecting suspension systems to manage thermal expansion in hydraulic networks:
- Ability to adapt to thermal variations: Choose systems allowing controlled movement of pipes during temperature changes
- Fixed and mobile points: Combine strategic fixed points with mobile supports such as sliders
- Load resistance: Ensure that supports can bear the weight of pipes filled with fluid
- Material compatibility: Select systems adapted to the specific materials of the pipes to avoid galvanic corrosion
- Thermal insulation: Use insulating clamps to prevent thermal bridges and condensation
These characteristics ensure the longevity and efficiency of hydraulic networks while preventing mechanical stress due to expansion.
- Pressure resistance: Ability to withstand maximum service pressures of the network
- Suitable materials: Steel, stainless steel, or specific alloys depending on the environment
- Fluid compatibility: Resistance to corrosion and chemical properties of the transported fluid
- Connection type: Appropriate threads (NPT, BSP, JIC) or flange fittings depending on the application
- Sealing: Reliable sealing systems (O-rings, bearing surfaces)
- Vibration resistance: Ability to maintain sealing despite system vibrations
- Temperature range: Compatibility with the network’s thermal variations
- Ease of installation and maintenance: Accessibility and disassembly
The main types of fittings for hydraulic networks intended for domestic installations are:
- Threaded fittings (NPT, metric DIN, unified) – allowing screwed connections
- Compression fittings – ensuring sealing without welding
- PVC fittings – for cold water pipes (up to 60°C)
- CPVC fittings – suitable for hot water systems (up to 93°C)
- Brass fittings – resistant to corrosion and pressure
- Stainless steel fittings – for corrosive environments
- Elbows, tees, sleeves, and reducers – for orienting and adapting networks
At SUFIX, we offer complementary support solutions to ensure the stability and durability of your domestic hydraulic installations.
The modular design of Sufix support systems simplifies the installation and maintenance of hydraulic networks by offering assembly flexibility that reduces assembly time. Standardized components interconnect easily, allowing installers to quickly create structures adapted to each configuration.
This modularity also facilitates maintenance by allowing selective replacement of parts without dismantling the entire system, while offering the possibility to adjust or extend existing installations according to evolving needs, thus ensuring durability and adaptability of hydraulic networks.

Here are our maintenance recommendations to ensure the longevity of electro-galvanized steel fixing rails:
-
Perform regular visual inspection to detect any signs of corrosion or wear
-
Avoid exposure to overly humid or corrosive environments, as electro-galvanized steel is not suitable for outdoor use
-
Clean periodically with a dry cloth to remove dust and debris
-
Occasionally apply a zinc-compatible anti-corrosion product in high humidity areas
-
Regularly check the tightness of fixings to maintain stability and prevent vibrations
-
Avoid contact with aggressive chemicals that could damage the zinc layer
-
In case of scratches, quickly apply a zinc-rich paint to restore protection
Preventing thermal bridges in support systems for insulated pipes is crucial for several technical reasons.
First, these bridges significantly compromise the overall energy efficiency of the system, creating points of heat loss that can represent up to 20% of total thermal losses.
Second, the temperature difference at these contact points inevitably generates condensation, leading to corrosion and premature degradation of materials. In cooling systems, this moisture can damage not only the pipes but also surrounding equipment.
Insulating clamps, such as those from Sufix’s PIRFLAM or PIRFLEX range, effectively solve this problem by ensuring perfect continuity of the vapor barrier, thus maintaining the thermal integrity of the entire network and considerably extending its operational lifespan.
