Question:<\/strong><\/p>\n\n\n\n

How can I remove stains during aluminum pickling?<\/p>\n\n\n\n

Answer from Trawialnia's Technical Advisor:<\/strong><\/p>\n\n\n\n

Visible stains are caused by incorrect application and choosing the wrong product. When pickling aluminum, we recommend using the PROCAP A7<\/a> spray agent \u2014 a gel that won\u2019t run off. Apply it with the M5 pump for an even mist of the agent.

Question:<\/strong><\/p>\n\n\n\n

How can I remove corrosion from a plate heat exchanger?<\/p>\n\n\n\n

Answer from Trawialnia's Technical Advisor:<\/strong><\/p>\n\n\n\n

Surfaces that come into contact with water can face two problems: scaling and corrosion. Corrosion is caused by a chemical reaction \u2014 the water\u2019s chemistry affects stainless steel (steel-water interaction).\nWe recommend using:<\/p>\n\n\n\n

    \n
  • PROCIV DER A1 80% in 45 \u00b0C,<\/li>\n\n\n\n
  • PROCIV 600,<\/li>\n<\/ul>\n\n\n\n

    Question:<\/strong><\/p>\n\n\n\n

    We have a 321 steel pipe that has been annealed after welding, leaving it covered in scale and discoloration. How do we remove this discoloration and passivate the welds?<\/p>\n\n\n\n

    Answer from Trawialnia's Technical Advisor:<\/strong><\/p>\n\n\n\n

    We recommend a new product from Chimimeca's innovative range.
    The pipe only requires pickling with Procap SN+<\/strong>.
    Reaction time is 1 hour. After application, the agent dries quickly on the discolored areas, so after about 10 minutes, you should re-spray those spots. Ambient temperature: approx. 19\u00b0C.<\/p>\n\n\n\n


    Amazing and fast results with Procap SN+<\/strong>. When using standard products available on the market, the pickling process usually has to be repeated multiple times.<\/p>\n\n\n\n
