STAUFF CLAMPS

STAUFF CLAMPS IN STOCK

STAUFF Clamps have stood for quick, easy, and secure installation of pipes, tubes, hoses, cables, and other flexible and rigid components with outside diameters up to 1,016 mm / 40 inch for more than 50 years.

​

Their vibration and noise reduction capabilities are regarded as a significant contribution to environmental protection as well as occupational health and safety.

​

One of STAUFF's numerous unique capabilities is the processing of fire-resistant clamp body materials that have been tested and authorized according to many international fire-protection standards (such as BS 6853, EN 45545-2, and UL 94).

​

Even for tailored solutions based on customer specifications or in-house development, STAUFF promises timely response.

​

STAUFF uses the STAUFF Zinc/Nickel surface coating for the finishing of its carbon steel pipe, tube, hose, and cable clamps, as well as metal accessories. The STAUFF Zinc/Nickel surface coating has been proven successful for many years. It offers reliable surface protection, even after transportation, handling, and assembly, and it complies with all current legal standards.

​

V2A and V4A stainless steel versions are commonly available from stock. On request, alternative materials and surfaces are available.

Polypropylene Stauff Clamp Standard Series with Cover Plate, Weld Plate & Hex Bolts

STAUFF Zinc/Nickel Coating

The STAUFF Zinc/Nickel surface coating provides outstanding surface protection – even after transit, handling, and assembly – with at least 1200 hours of red rust resistance. Testing in a salt-spray chamber according to DIN EN ISO 9227 proved this.

​

Users in all industries and applications benefit from sophisticated technology that has been developed for and used by the extremely demanding automobile industry for many years and has been the proven standard for a substantial number of STAUFF components since 2007.​

  • Resistance against red rust / base metal corrosion for at least 1200 hours in a salt-spray chamber under real-world conditions, according to DIN EN ISO 9227.

  • The only sign of white rust is a little grey haze.

  • Exceeding the standards of the VDMA's corrosion protection class K5 (360 hours resistance to white rust / 720 hours resistance to red rust).

  • Cr-free hexavalent chromium (VI)

  • ELV compatible in accordance with 2000/53/EC (End of Life Vehicles Directive)

  • REACH-compliant (Registration, Evaluation, Authorization, and Restriction of Chemicals) pursuant to Regulation 1907/2006/EC

  • RoHS compliant in accordance with Directive 2002/95/EC (Restrictions of the Use of Hazardous Substances)

  • Color scheme is appealing, with a bright semi-gloss surface quality that is close to stainless steel.

  • Corrosion caused by interaction with other metals is significantly decreased (such as Aluminium and Stainless Steel)

  • Abrasion resistance is improved due to the coating's ductility and plastic deformability.

  • Nickel release is a fraction of the statutory limits for objects that come into direct and prolonged contact with the skin (independent results of the reference test technique according to DIN EN 1811 are available on request) and has little to no danger of provoking allergies.

  • Paint adhesion qualities that are good

  • All regularly used hydraulic media are resistant.

BASIC INSTALLATION INSTRUCTIONS

Installation on Weld Plate

For all STAUFF Clamps that comply with DIN 3015, as well as most other series and many custom-designed special clamps, many types of weld plates are available.​

​

  1. Place the weld plates in their proper locations. Please double-check that these positions are appropriate for the anticipated loads.

  2. To guarantee the best alignment, mark the positions of the weld plates.

  3. Place the weld plates in place and weld them in place. Screws or bolts can also be used to secure elongated weld plates in place.

  4. Half of the bottom clamp should be pressed against the weld plate.

  5. Insert any sort of line, including pipe, tube, hose, cable, and so on.

  6. Place the second clamp part on top, along with the cover plate (optional), and secure the clamp assembly with screws or bolts.

Stauff Clamp Installation on Weld Plate

The bolt lengths for clamps according to DIN 3015 pertain to installation on weld plages and mouting rails, as well as multi-level (stacking) installation, unless otherwise stated. Different lengths may be necessary for direct installation.

Installation on Mounting Rail

STAUFF Mounting Rails come in a variety of heights. STAUFF Rail Nuts are available for all DIN 3015 STAUFF Clamps (Heavy Series up to STAUFF Group 6S only), as well as several custom-designed customized clamps.

​

  1. Place the mounting rails in their proper locations. Please double-check that these foundations are adequate for the anticipated loads.

  2. To achieve the optimal alignment, mark the positions of the mounting rails.

  3. Place the mounting rails in place and weld them in place. Side-mounting brackets with screws or bolts can also be used to secure mounting rails in place.

  4. Insert rail nuts into mounting rails and tighten (Standard and Twin Series) or slide in rail nuts (Heavy Series).

  5. Half of the bottom clamp should be pushed onto the rail nuts.

  6. Insert any sort of line, including pipe, tube, hose, cable, and so on.

  7. Place the second clamp part on top, along with the cover plate (optional), and secure the clamp assembly with screws or bolts.

Stauff Clamp Installation on Mounting Rail

Before the clamp components are firmly fastened together, the exact placements of the clamp assemblies can be changed.

Multi-Level (Stacking) Installation

Stacking bolts allow clamps of identical group sizes to be assembled on many levels. The stacking bolts are prevented from twisting by safety locking plates inserted between the layers. Different group sizes (STAUFF Groups 2D to 5D) can be stacked in the Twin Series.

​

  1. Half of the bottom clamp should be pressed against the weld plate or rail nuts.

  2. Insert any sort of line, including pipe, tube, hose, cable, and so on.

  3. Place the second clamp half in place.

  4. Tighten the clamp halves in contact with the line over the full internal contact surface by inserting stacking bolts into the clamp assembly and tightening to the following torques:

    • Standard Series : 1 ... 2 N·m / .75 ... 1.5 ft·lb (hand-tightened) ​

    • Heavy Series : 5 N·m / 3.75 ft·lb

    • Twin Series : 1 ... 2 N·m / .75 ... 1.5 ft·lb (hand-tightened)

  5. On top of the clamp assembly, place the safety locking plate.

  6. Continue to the next level. Cover plate and hexagon head bolts will be used to assemble the top level.

Stauff Clamp Stacking Installation

Both weld plates and mounting rails can be used to mount STAUFF multi-level clamp systems (with rail nuts).

INSTALLATION NEXT TO PIPE BENDS, CONNECTORS / COUPLINGS & VALVES

Stauff Clamp Installation to Pipe Bends, Connectors, Couplings & Valves

Please take note of the following details while installing STAUFF Clamps near pipe bends, connectors / couplings, and valves:

Pipe Bends

Connections / Couplings

STAUFF Clamps should be used to support pipe bends as close to the bends as possible. Furthermore, these clamps should be designed as fixed point clamps.

The first clamp should go right adjacent to the connector or coupling. The connector / coupler is therefore protected from vibrations.

Valves

If pipelines have valves, it is advised that support be provided in front of and behind the valves.
