Stauff Pipe Clamps
|
A Stauff clamp is a clamp that is used to grip tubes, pipes, and hoses along hydraulic systems. The actual purpose of the clamp itself is to keep the hydraulic system stable. They help reduce the impact and vibration that fluid flow creates. There are three different versions in the series of Stauff clamps. There is the standard series, heavy series and the twin series.
The clamp body is made of polypropylene (PP), polyamide (PA), aluminium (AL), and polypropylene with rubber insert (RI). Installation of Stauff Clamps are very easy as it only involves fixing the clamp itself onto a stable surface and wrapping the clamp along the pipe tightly in order to avoid any slack in the clamp. |

What are uses of Pipe Clamps
1. What is a pipe clamp used for?
A Stauff pipe clamp can refer as a tube clamp, a pipe clamp as well as hydraulic brackets. In essence they hold the pipes or tubes in place, keeping it stable and gripping it along its axis so that it stays still. The Stauff clamp that is available are made following the standards of the Deutsches Institut für Normung, better known as DIN. Specifically, the Stauff clamp follows the DIN 3015 standards.
Aluminium (AL), Polypropylene (PP), Polyamide (PA)
|
The clamp body is made of Polypropylene (PP), Polyamide (PA), Aluminium (AL), and Polypropylene with Rubber Insert (RI). These selections allow for the best performance in stabilisation and clamping of the pipes as well as temperature range system. Polypropylene material, green colour is able to work under temperatures ranging from -30˚C to +90˚C, while Polyamide, black colour works in temperatures ranging from -40˚C to +120˚C. Aluminium material, silver colour can work at a highest temperature, which is up to 300˚C. The clamps colours differently will differentiate the materials usage and lead to different temperature ranges. As for the metal component, it uses carbon steel as well as Stainless Steel SS316.

3. How do you clamp a pipe in assembly set?
There are many ways that a pipe clamp can be put together, in order to make it most effective for its purpose. Something as simple as a base plate connected to a top plate by a hex bolt with the clamp body in the middle can be enough at times, but other more creative methods are certainly not out of the question for certain configurations. There is a possibility of using a few rail nuts in order to increase the height of the clamp, or to put two clamps on top of each other using two pairs of the clamp body and a safety locking plate.
Please look at components combination below in order to customize the installation option:

4. How do you install a pipe clamp?
Stauff clamps can also be easily disassembled due to this property. Due to the fact that Stauff clamps easily configured in different manners, this means that it only requires a few creative workarounds if space is not available, and it is an option to combine different Stauff Clamps together in order to create a working system of clamps that is effective.
There are many different types of weld base plate designed according to DIN 3015 in order to install in various customizable special clamps design. Please refer to different installation methods according to job requirement:

Option 1: Base plate installation
Base plate installation is the most common basic application. The base plate are used to mount to the wall or ceiling and the clamps can be inserted easily before final tightening with cover plate and bolts and screws. There are two common type of threads, metric thread and unc thread to tighten the complete set of clamps. Step 1: Place base plate in the designated positions, kindly make sure the positions are suitable for system expected loads. |
Step 2: Mark the positions of the base plate to ensure the best system alignment.
Step 3: Weld the base plate into position and alternatively, elongated base plate is another option to be mounted to their positions by using two screws or bolts at both ends without any welding job.
Step 4: Push the one halves of the clamp to bottom on the base plate.
Step 5: Insert pipe, tube, cable, hose or any other type of line.
Step 6: Place the second halves of the clamp and cover plate on top and mount the complete clamp installation by using bolts and screws.
The bolts length for clamp installation refers to the installation of the base plate and mounting rails as well as stacking level during the clamp assembly. The bolts length can be customized according to job design and clamp size upon request.

Option 2: Installation on mounting rail
Mounting rails are used in installation to allow the multiple sets of clamps to be positioned along the pipe or tube. With mounting rails, the clamps can be easily adapted before final tightening and additional sets of clamps can be added or removed without any problems. Rail nuts have been made to optimize further and adapted the shape. The bottom part was lightly chamfered on both ends and the rail nuts can be screwed in further to create additional contact surface area with the mounting rail. |
Stauff PA Clamp Body

The groove on the top provides a stronger attachment of the rail nuts in the mounting rail. The interaction of chamfers and grooves ensures that the rail nuts continue to remain in a temporary position even during temporary dismounting of clamps so that they will not slide out of the mounting rail as before. The conformation of the rail nut in the upper section was adapted with the plastic cap to ensure secure seating of the clamp body for vertical and overhead installation. The is no longer slides from the part and the chances of loosening will decrease as well.
Step 1: Place mounting rail in designated position and kindly ensure the expected loads is counted into consideration.
Step 2: Mark the positions of the mounting rail to ensure the best system alignment.
Step 3: Weld the mounting rails into position or it can be mounted by using side-mounting brackets with bolts or screw.
Step 4: Insert rail nuts into mounting rail and turn the position until they are locked at mounting rail for standard and twin series, while the rail nuts for heavy series has be installed through sliding in from the end of the mounting rail.
Step 5: Push one halves of the clamp body to bottom on the rail nuts.
Step 6: Insert pipe, tube, cable, hose or any other type of line.
Step 7: Place the second halves of the clamp and cover plate on top and mount the complete clamp installation by using bolts and screws.
The rail nut actual positions of the clamp assemblies can be adjusted before being firmly bolted.

Option 3: Installation of stacking clamp
The combined usage of safety locking plates and stacking bolts in clamp assembly make it possible to mount multiple clamp bodies of the identical size directly on top of one another. Installer can increase the flexibility in the design and layout of pipeline systems with the use of stacking clamps. This is because several lines running close together no longer have to be positioned side by side. Safety locking plates are insert between the levels of clamps to prevent the stacking bolts from turning around. |
Step 1: Push bottom clamp halves onto the base plate or rails nuts.
Step 2: Insert pipe, tube, cable, hose or any other type of line.
Step 3: Place the second halves of the clamp.
Step 4: Insert one piece of stacking bolt into each single bolt hole on the clamp during assembly and tighten using the tightening torques.
Step 5: Place safety locking plate on top of the first level of clamp body assembly.
Step 6: Proceed with the next levels. Insert cover plate and hexagon head bolts when reaching the top level of clamp assembly. Tighten the bolts and refer to tightening torques table.
The stacking clamps installation can be mounted both to mounting rails or base plate.
Step 2: Insert pipe, tube, cable, hose or any other type of line.

5. What is clamp tightening torques?
The tightening torque value can be traced by torque wrench in analogue or digital formats. It is important because an under torqued bolt will deform and it is unable to provide as much clamping force as needed and an over torqued bolt will break the clamps upon installation. All bolts have to be pre-tightened by hand before applying the full tightening torque. Please refer to tightening torque values below:

6. What is the recommended distance between clamps?
The clamp recommended distances between clamps are important information during installation. For instance, the recommended distance to install a Stauff clamp is 1 meter away for tube outer diameter of 6 to 12.7 mm, but it can get up to as far as 7.5 meters away when the O.D of the pipe is 356 - 406 mm. The clamp lifetime can be improved if the clamp can keep in a closer distance.

Pipe bends should be supported by clamps as near to the bending curve as possible. It is recommended to design clamps in a fixed point to keep flow consistence. The first clamp should be placed directly behind the threaded coupling or connector. This is to reduce vibration for the threaded coupling or connector. If valves are incorporated in the pipelines, it is recommended that support shall be provided in front and behind of the valves.
