Pickling paste and pickling gel
|
|
Avesta pickling pastes and gels are used to remove welding oxides and the underlying chromium-depleted layer.
|
|
The paste and the gel also remove micro-slag particles and other contaminants that may cause local corrosion. To assist pickling, this process may sometimes be combined with some form of simultaneous mechanical treatment, for example brushing.
After pickling, the workpiece should be thoroughly rinsed with clean water. The best results are achieved by using a high-pressure water jet.
To avoid smut formation and instantly restore the protective chromium oxide layer, a final passivation/decontamination step (using Avesta 630 or 601) is recommended.
Avesta pickling paste and pickling gel follow the recommendations of ASTM A-380 A.1 and BS CP-312.
| Avesta Classic products and application |
 |
Avesta Classic Pickling Paste 101 is the original and only real paste on the market. It offers a perfect paste consistency that gives good adhesion to difficult surfaces and reduces the risk of splashing. |
 |
Avesta Classic Pickling Gel 122 is more free-flowing than the paste to facilitate application. The gel is also more heat-stable which makes it suitable for use in warmer climates. |
Avesta BAT products and application |
Environmental Management using Best Available Techniques ( BAT ) are required under ISO 14000 and EC Directive 96/61, in order to create a safer working environment. The ISO 14000 is primarily concerned with "environmental management". This means what the organization does to:
- minimize harmful effects on the environment caused by its activities, and to
- achieve continual improvement of its environmental performance
This definition implies that BAT not only covers the technology used but also the way in which the installation is operated, to ensure a high level of environmental protection as a whole. BAT takes into account the balance between the costs and environmental benefits.
