Onsite Treatments

We offer a convenient service of bringing the stainless steel cleaning and pickle and passivation process directly to our customers

ICS International Corrosion Services can perform cleaning, pickling and passivation of stainless steel onsite and in compliance with with standards ASTM A380, ASTM A967, AS 1627.1 & AS 1627.5

- The treatments can include treatment of all surface areas in compliance with the above standards
- Alternatively can also offer an isolated process of treatment of the weld seams only.
- A certificate of conformity is issued after every treatment

Result of Pickle and Passivation Treatment:
- Treats all heat affected areas 
- Removes all surface contaminants that could lead to premature tea staining and corrosion.
- Restores the stainless steel chromium layer that allows the stainless to perform at its best.

Benefits:
- Reduces tea staining, corrosion and pitting.
- Reduces maintenance and cost of ownership.
- Increases durability and longevity of the asset.

Please call us to discuss the best treatment option for your project.

    Offshore

    ICS are no strangers to treating stainless steel offshore facilities.

     Stainless steel is a common element of oil and gas platforms and other offshore facilities. While stainless steel is used several ways for offshore facilities – including hydraulic lines and over a wide range of temperatures – improper maintenance can lead to corrosion, compromising its structural integrity. Our team attended the subsea stainless steel Motion Record unit assemblies for a Floating Storage & Production Offtake (FPSO), based offshore Angola. The treatment carried out used pickling paste, cleaner and passivator as well as mechanical abrasion to remove corrosion on the subsea canisters. The work was carried out as per standard ASTM A967.
    Scheduled Maintenance

    Surface deposits, contamination and corrosion must be prevented to prolong the life and integrity of stainless steel.

    The environments and conditions stainless steel is subjected to can have a major impact on its longevity and the frequency in which maintenance works should be carried out. Typically, more aggressive environments (such as marine equipment) prove more difficult for stainless steel to resist without the correct cleaning and maintenance. Choosing the correct maintenance schedule for stainless steel, and a prompt response to any stains or discolouration can aid in the prevention of serious problems with stainless steel. It is important to note that simply wiping with a damp cloth will smear corrosive deposits without removing them, therefore it is important to use the correct chemicals and techniques.Depending on the grade, environment and surrounding material contamination ICS may recommend scheduled cleaning frequencies from either three, six or twelve months or only as required.
    Common signs of corrosion
    Stainless steel is an ideal material for many uses, including structures, industrial equipment and commercial plants. Steel is a common choice due to its strength, and stainless steel’s excellent corrosion and staining resistance is ideal for these applications all over the world.

    However, stainless steel can be susceptible to localised corrosion, or uniform corrosion if exposed to basic or acidic solutions. Some corrosion can be difficult to predict and protecting stainless steel with the proper maintenance is critical to keep the integrity of your structures or equipment.

    Depending on the environment in which stainless steel is used, surface deposits can cause staining and discolouring. The correct grade, finish, maintenance and cleaning schedules are required to maintain stainless steel’s best performance.

    Pitting Corrosion

    Pitting is a form of corrosion which is often readily visible to the naked eye and is a symptom of the chromium-rich passive oxide film on tubing breaking down due to exposure in a chloride-rich environment. A higher chloride concentration or increased temperature likely to result in the passive film breaking down. Pitting is not only unsightly, it can eventually cause a situation where tubing could fail. Without the passive film intact to protect the steel, pitting and perforation can occur. While pitting will initially form in the shape of shallow pits, continued lack of proper maintenance will see the corrosion develop to deep and even connected pits.

    Crevice Corrosion

    Crevice corrosion can be extremely difficult to avoid in tubing. Tight crevices are the biggest risk to steel, with corrosion causing the oxygen concentration in the fluid within to drop. This lower oxygen concentration increases the likelihood of the passive surface oxide film breaking down, resulting in a shallow pit.
