Most manufacturers claim less than 10ppm others ppm. NOTICE When migrating the old forums over to our new forums we were unable to retain the identity of the authors, so the old posts will show up as “anonymous”.
Also, remember that external sources of chlorides usually cause more damage than the ppm chlorides found in insulation materials.

It has a long reputation as a credible, non-biased source for test methods and material standards, and as such can be an essential resource for specifiers who are looking for insulations with excellent CUI performance. While the older corrosion test strictly relies on visual results, C provides objective, quantifiable data of the actual metal loss due to corrosion caused by the chemical formulation of the various insulations.
They are WK and WK Re your insulation vs. Industry members at all levels should educate themselves on the science behind corrosion and be able c7795 logically explain how insulation plays a role.
Helps manufacturers ensure their chemical formulations help reduce the potential for CUI being caused by the insulation itself. Other methods involve removing a small percentage of the insulation in CUI-prone areas, inspecting the base metal, and then re-covering the exposed pipe with new insulation and aastm. Preproduction corrosion test and chemical analysis shall be performed to conform to the specified requirements.
Are you sure you want to empty the cart? The asrm and chemical requirements shall conform to the requirements of the basic material specification. This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment. The material shall conform to the established requirements of the basic material specification.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Historical Version s – view previous versions of standard. So the insulation needs to be tight from moisture intrusion. Remember me for one month.
One thing many fail to realize is that ASTM is a consensus group, meaning that edits, additions, or deletions to a document must receive approval from every member that votes on the issue. There are several different test methods that help designers evaluate corrosion rates.
However, such methods involve costly equipment and can evaluate only a small area at a time. There are several non-destructive methods for detecting in-situ metal loss without removing the insulation, such as infrared scanning. One must take the time to read the actual material standard to see what the passing criteria are because, as noted above, they can vary from one material standard to another. The physical and chemical requirements shall conform to the requirements asgm the basic material specification.

So please participate and share knowledge just as you have in the past. Most ASTM material standards for industrial insulation contain one or more of these test methods regarding corrosion. F Standard Specification for Driven Fasteners: Testimonials Contact Us Sitemap.

Understanding ASTM Test Methods Evaluating Thermal Insulations and Corrosion of Metals
ASTM International plays an important role in providing the technical data and physical properties for a broad range of materials, including insulation.
In addition to meeting the requirements f795 in their individual material specifications, issued under the jurisdiction of ASTM Committee C16, these insulations must pass the asgm test requirements of Test Method Cfor stress corrosion effects on austenitic stainless steel, and the confirming quality control, chemical requirements, when tested in accordance with the Test Methods C The following is a list of brief explanations of 4 commonly specified corrosion ASTM material standards and test methods.
In addition to meeting the requirements specified in their individual material specifications, issued under the jurisdiction of ASTM Committee C16, these insulations must pass the preproduction test requirements of Test Method Cfor stress corrosion effects on austenitic stainless steel, and the confirming quality control, chemical requirements, when tested in accordance with the Test Methods C Whether or not a given insulation material standard contains a particular test method is a function of how old the latest version is, how active the ASTM committee members are, or the difficulty in gaining consensus among the members to add or modify existing standards.
