This specification astk non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment. It has been required that they are to contain not more c95 5ppm of Cl content. The physical and chemical requirements shall conform to the requirements of the basic material specification. 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.
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. If you like to setup a quick demo, let us know at support madcad. Preproduction asrm test 7c95 chemical analysis shall be performed to conform to the specified requirements.
This protects the broader community and prevents individuals or groups from passing self-serving standards that do not benefit the industry as a whole. Stay Current Sign up for our quarterly newsletter covering updates on corrosion. ASTM International plays an important role in providing the technical data and physical properties for a broad range of materials, including insulation.
Now what confuses me is that does the claim of this manufacturers possibly real and is the required specification of not less than 5ppm attainable? Page 1 of 1. Enter your account email address to request a satm reset: This abstract is a brief summary of the referenced standard.
Understanding ASTM Test Methods Evaluating Thermal Insulations and Corrosion of Metals
So please participate and share knowledge just as you have in the past. This also helps engineers know that every word of the standard is deliberate and agreed upon by all of the members of the committee.
We do not know if this minimum can me consistently met; however, ASTM www. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Industry members at all levels should educate themselves on the science behind corrosion and be able to logically explain how insulation plays a role. Register for a trial account.
The safe operation of oil refineries in the United States is under constant r There are several non-destructive methods for detecting in-situ metal loss without removing the insulation, such as infrared scanning.
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. C7955 to Active This link will always route to the current Active version of the standard. Most manufacturers claim less than 10ppm others ppm. Generic material standards are often specified by engineers to ensure competition and not show favoritism to one manufacturer astj another.
The coupons are weighed before the test, and are c7995 again after the test once the coupon has been cleaned to remove corrosion products formed during the test. Caution is advised here as some specifications are not generic, but instead insulation specific. 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.
Historical Version asfm – view previous versions of standard. F Standard Specification for Driven Fasteners: However, such methods involve costly equipment and can evaluate only a small area at a time.
Remember me for one month. The following is a list of brief explanations of 4 commonly specified corrosion ASTM material standards and test methods. C79 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”. The most predictable and cost-effective method to manage CUI is a systematic inspection program. Discussion Forums – The Hendrix Group.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Many facilities departments tasked with creating and implementing an effective CUI-inspection program report very limited budgets and available personnel to carry out this critically important task, which must continue in perpetuity. Helps manufacturers ensure their chemical formulations help reduce the potential for CUI being caused by the insulation itself.

Your stated minimum operating temperatures of C are also above where we would anticipate chloride SCC issues unless the component cycles frequently. All NEW posts will show up credited to their authors.

Leachable Chloride Content of Thermal Insulation
Please login to axtm authorized staff account to use this feature. In addition to meeting the requirements specified in their individual material specifications, d795 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 C Terminology Relating to Thermal Insulation.
This would be a great way to increase credibility of the industry, help lower energy costs, and reduce CUI potential within affected systems.
