Unlike ferrous iron-based steel that rusts, stainless steel will fail through a process known as external stress corrosion cracking ESCC. One asrm 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.
Corrosion under insulation CUI is one of the most significant issues facing industrial facility owners, engineers, and maintenance personnel who work with above-ambient process piping and equipment. This abstract is a brief summary of the referenced standard.
We do not know if this minimum can me consistently met; however, ASTM www. In addition to meeting the cc795 specified in their individual material specifications, issued under the jurisdiction asstm 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 Test methods are exactly that—they lay out a plan to test, evaluate, and report specific physical properties.
If the steel shows any cracking under a microscope, the insulation will fail. These test methods then set the minimum standards that insulation products must pass in order to be considered safe for specific applications. While the older asm 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 asgm insulations. Caution is advised here as some specifications are not generic, but instead insulation specific.
The safe operation of oil refineries in the United States is under constant r The physical and chemical requirements shall conform to the requirements of the f795 material specification. Generic material standards are often specified by engineers to ensure competition and not show favoritism to one manufacturer or another.
The coupons are weighed before the test, and are weighed again after the test once the coupon has been cleaned to remove corrosion products formed during the test.

Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.
ASTM International plays an important role in providing the technical data and physical properties for a broad range of materials, including insulation.
Leachable Chloride Content of Thermal Insulation
The following is a list of brief explanations of 4 commonly specified corrosion ASTM material standards and test methods. Historical Version s – view previous versions of standard. No items in cart. Abstract This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment.
This test method has been adopted into several, but not all, insulation material standards. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. So the insulation needs to be tight from moisture intrusion. Leachable Chloride Content of Thermal Insulation. Please login to your authorized staff account to use this feature. The most predictable and cost-effective method to manage CUI is a systematic inspection program.
In this program, specially-trained workers carefully cut cores out of the insulation system, perform a visual inspection of the base metal, and then install properly sealed inspection plugs.
This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment. This also helps engineers know that every word of the standard is deliberate and agreed upon by all of the members of the committee.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Helps manufacturers ensure their chemical formulations help reduce the potential for CUI being caused by the insulation itself. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Land Use and Development. This means that it is possible for 2 different insulation materials to meet their own minimum requirements, but one may suit a particular application better than the other as to one or more attributes.
Most ASTM material standards for industrial insulation contain one or more of these test methods regarding corrosion.
When migrating the old forums over to our new forums we were unable f795 retain the identity of the authors, so the old posts will show up as “anonymous”.
It has been required that they are to contain not more than 5ppm of Cl content.
