Stauff Anti Corrosion Clamps
|
ACT Clamps, an abbreviation to Anti-Corrosion Technology Clamps, are used to obtain structural support by reducing vibrations and noise throughout systems. The new clamp designed from original stauff clamps according to DIN 3015. It is available in standard and twin series only.
The clamp accessories can be installed with different alternative and it is made of stainless steel W55 with enhanced corrosion resistance by practically excluding metallic and non-metallic impurities during production, processing and handling. It is suitable for continuous exposure to temperatures from -25°C to 80°C or from -13°F to +176°F. |

What are ACT clamps
1. What is ACT used for?
These are most suitable to use in harsh environmental conditions such as sub-sea, top-side and oil rigs. The clamps are very useful in preventing pit corrosion on stainless steel tubes and other such structures. The ACT clamp body made of flame-retardant PPV0 plastic material. It is being called as anti-crevice tubing support or anti corrosion clamp.

2. What can corrode stainless steel pipe installation?
Under specific conditions particularly involving chlorides such as sodium chloride in seawater and exacerbated by elevated temperatures, small pits would form in a material surface especially stainless steel. These pits may continue to grow and eventually lead to perforation of tubing wall and leaks in long term, while the majority of the surface may remain uninjured. Small single pit becomes deeper and connected pits corrosion can be easily observed by visual inspection with the unaided eye.

Another factor is crevice corrosion. Pipe clamp made of PVC plastic material in particular have been prone to produce crevice corrosion in the past. This is because plastic deforms around the tubing and creates an even tighter crevice. Crevice corrosion can cause serious consequences eventually leading to perforation of tube wall thickness and the escape of highly flammable liquids and chemicals.
Crevice corrosion is initiated by changes in the local chemistry within the shielded area, usually associated with a stagnant solution on the micro-environmental level. |
Example as below:
- A shift to acid conditions
- Trapped seawater becomes stagnant
- Depletion of inhibitor and oxygen
- Build-up of aggressive ions division such as sodium chloride in seawater
3. What is ACT Clamp made of?
The material and the design for ACT clamps are chosen in compliance with the Norwegian Offshore Norzok Z-010 Standards, API RP 552, standard tubing installation and NACE SP 0108-2008 norms. The clamp body is made of fire, rain, oil and seawater resistant PPV0 plastic material that is tested and classified as V0 according to UL94.

The body consists of integrated anti-corrosion elastomer strips that avoid the accumulation of seawater between the clamp body and the pipe. The dynamics of these strips create drainage channels to aid dispersal of water. This new ACT clamp designed offers time reduction during installation and long-term cost savings due to extended service intervals.
The ACT clamp size we be covering the most common used metric and imperial pipe diameters from 6mm to 25.4mm, which from 1/4" to 1”. Various pipe diameter is available upon request. Polypropylene or polyamide material has a wider size range from 6mm to 406mm. |

There are different types of assembly versions to cater them. It is always recommended that you mark the location of the alignment of the weld plates during their installation. To assemble the complete unit, it is required that you push in the bottom half of the clamp, install the tubing, as well as mount the top half of the clamp together with the help of a cover plate and bolts.
The stacking clamp design increases installation flexibility. The combine usage of specially designed safety locking plate (SIG) and stacking bolt (AF) makes it possible to mount multiple clamp bodies of the identical size directly on top of another. The flexibility benefits to designer and the layout or design of pipework system to save some space in between.
