  • Sodium Hydroxide (25%) for pH Control, Boiler Feedwater

    Description. Accepta 1025 is a high quality concentrated sodium hydroxide (caustic soda) solution available at 25% for use in the treatment of boiler feedwaters. Accepta 1025 can also be used to regenerate anionic resins in deionisation plants. It can also be used for most neutralisation processes where the pH must be raised.Get Price

  • LIQUID CAUSTIC SODA (Sodium Hydroxide)

    Concentration of caustic (NaOH) can occur as a result of steam blanketing (which allow salts to concentrate on boiler metal surface) or by localized boiling beneath porous deposits on tube surface. Caustic corrosion occurs when caustic is concentrated and dissolves the protective magnetite (Fe 3 O 4 ) layer, causing a loss of base metal and eventual failure.Get Price

  • What is Caustic Corrosion? - Definition from Corrosionpedia

    Nov 22, 2021 · What is Caustic Embrittlement? Caustic embrittlement is a phenomenon that takes place in a steam boiler when the caustic substances gather in the materials of the boiler. It is also characterized by the cracking of riveted mild steel boilerplates. Caustic embrittlement takes place at the temperature range of 200°C to 250°C.Get Price

  • Caustic corrosion in boilers - Lenntech

    Caustic soda (NaOH) is the only normal boiler water constituent that has high solubility and does not crystallize under typical boiler conditions. Its caustic concentration can be as high as 10,000-100,000 ppm. Careful control of boiler water chemistry can prevent caustic gouging. If the "free hydroxide alkalinity" is set too high or uncontrolled, then caustic gouging may result. Prevention …Get Price

  • Boiler Boil-Out Suggestions - Banks Engineering

    13. Fire the boiler at a very low firing rate to limit the flue gases entering the boiler to a maximum of 800°F. Alternately, introduce 5 psig steam from an outside source through the blowdown nozzles. 14. When the boiler begins to produce steam (as seen though the open vents), allow the unit to steam freely for at least four hours.Get Price

  • Boiler Wateside Corrosion | Walter Louis Fluid Technologies

    Caustic Attack: Caustic attack or, as it is more commonly known, caustic corrosion, is often encountered in phosphate treated boilers in which deposits occur in high heat transfer areas. In particular, boiler water can permeate the porous deposit. When it is coupled with significant heat flux, concentration of the boiler water occurs.Get Price
