Chemical Cleaning

 

Expert boiler cleaning and pipeline chemical cleaning solutions

Piping and vessels may contain unwanted debris and contaminants. If you’re looking for a safe and effective method to clean the surfaces and walls of your pipeline and vessels, chemical cleaning is a proven effective method. Process Chemicals has forged a strong association with the mining and oil & gas industry, providing excellent pipe cleaning services.

We’re one of the most experienced and qualified specialised onsite chemical cleaning companies in Australia. We have more than 30 years of industrial chemical cleaning practice, ranging from boilers and heat exchanges, to heating and cooling water systems and pipelines. Contact us for a quote.

In recent years, we have developed a specific onsite cleaning and passivation method for corrosion resistant alloys and other exotic metals, to deal with the increasing desalination market.

Our dedicated team continues to maintain the company’s edge over our competitors by working diligently, and continuously focussing on safety, service and value.

Our in-house chemist can tailor the right solution and develop a chemical cleaning program to suit your project’s cleaning needs, including:

  • Descaling

A chemical descaler is a method used for boiler cleaning. Descaling removes limescale from metal surfaces that are in contact with hot water.

  • Degreasing

Proper degreasing is essential to pipeline cleaning. The process is performed by applying alkali chemical cleaning solutions onto the pipe’s surfaces. The degreasing effect of the aqueous solution guarantee the optimum elimination of all forms of contaminants.

  • Pickling

Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminium alloys. A solution called pickle liquor, which contains strong acids, is used to remove the surface impurities. It is commonly used to descale or clean steel in various steelmaking processes.

  • Passivation

Passivation is the process we use to clean and protect stainless steel after it has been through a mechanical process such as machining or welding. Our passivation process removes free-iron from the surface of stainless steel and produces a thin, transparent oxide film, which protects the surface from corrosion.

  • Alkali washes

Acidic water is corrosive and alkaline water is more prone to scaling. A typically recommended alkalinity rating is 140 – 700 ppm for boilers operating below 300 psi. Alkali wash is a boiler chemical cleaning method that helps control the pH by either removing water impurities or adding other chemicals to neutralise the condition.
