Pipe clamps – for fastening and securing pipes, pipelines, hoses, or other components.

Pipe clamps according to DIN 3015 are essential fastening elements for the secure fixing of pipes, lines, hoses, and cables. They prevent unwanted movements and vibrations and provide organized fastening in hydraulic systems, mechanical engineering, and other industrial applications. They make a significant contribution to noise reduction, corrosion protection, and operational safety – even under high dynamic loads.

The areas of application are diverse: mobile and industrial hydraulics, mechanical and shipbuilding, offshore installations, energy and environmental technology, as well as the food and chemical industries – in short, everywhere reliable, vibration-damping line fastening is required.

Plastic (Polypropylene, Polyamide 6): Standard for many industrial applications; vibration- and noise-damping; resistant to oils, greases, and many chemicals; temperature range approx. -30 °C to +180 °C. Clamp halves are typically made of plastic.

Aluminum: For high temperatures up to approx. 350 °C and high stability in demanding environments.

Rubber: For special damping requirements; temperature range approx. -40 °C to +80 °C.

Stainless steel & galvanized steel: For bolts, cover plates, and weld plates; suitable for high mechanical and corrosion requirements.

DIN 3015 distinguishes three main series:

• Part 1 (Light series): Single clamps, typically for Ø 6–102 mm (e.g., “pipe clamp, single, Ø 6 mm” / “Ø 20 mm”).
• Part 2 (Heavy series): For larger or high-pressure pipelines.
• Part 3 (Double clamps): Parallel fastening of two lines, common Ø 6–42 mm (e.g., “pipe clamp, double, Ø 6 mm” / “Ø 28 mm”).

The size is always determined by the outside diameter of the line.

• Vibration and noise protection: Ribbed profiling, elastomer inserts, and suitable materials significantly reduce vibrations.
• Modular system: Fast, modular assembly/disassembly; suitable for single- and multi-layer installations.
• High holding forces: Secure fastening under static and dynamic loads, even overhead.
• Weather and corrosion protection: Suitable for demanding and humid environments.

Installation is carried out on weld plates, mounting rails, or directly on the structure. The modular system enables quick plug-and-bolt assembly from clamp bodies, cover plates, bolts, and nuts. Optional elastomer inserts provide additional damping and tolerance compensation. For higher resistance/hygiene, stainless steel parts are used.

Typical scope of delivery: 2× hexagon bolts (single) or 1× hexagon bolt (double), 1× cover plate, 2× clamp halves (plastic), 1× weld plate.

• Outside diameter & line type: Determine clamp size.
• Mechanical/thermal load: Choice of material and series (light/heavy, single/double).
• Chemical/environmental resistance: Selection of clamp body (plastic, aluminum) and metal parts (e.g., stainless steel).
• Single or double: Depending on the number of parallel lines to be fastened (DIN 3015 Part 1/2/3).
• Design & mounting type: Single, double, sensor, or special design; mounting on rail, weld plate, or directly. Consider environment, vibration frequency, and possible extensions.

Pipe clamps are largely low-maintenance. Regular checks of secure fit, wear of inserts, and corrosion of metal parts are recommended. Service life depends on material, load, and environment: plastic clamps remain stable and damping over the long term, while stainless steel parts are considered virtually unlimited in durability.
