Abstract This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment.

ASTM-C, –

This abstract is a brief summary of the referenced standard. 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.

No asfm in cart. Hope you anyone could enlighten me. Page 1 of 1. Remember me for one month. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Unlike ferrous iron-based steel that rusts, stainless steel will fail through a process known as external stress corrosion cracking Aatm. 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.

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 cladding.

As long as a given product meets the insulation-specific minimum requirements, it can be considered an eligible material to bid on the project. 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?

Generic material standards are often specified by engineers to ensure competition and not show favoritism to one manufacturer or another. There are several non-destructive methods for detecting in-situ metal loss without removing the insulation, such as infrared scanning.

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.

The physical and chemical requirements shall conform to the requirements of the basic material specification. ASTM does not give any warranty express or implied or make any representation that the contents of this astj are accurate, complete or up to date.

Understanding ASTM Test Methods Evaluating Thermal Insulations and Corrosion of Metals

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. This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment. C75 material shall conform to the established requirements of the basic material specification. Are you sure you want to empty the cart? Land Use and Development. If the steel shows any cracking under a microscope, the insulation will fail.

ASTM International plays an important role in providing the technical data and physical properties for a broad range of materials, including insulation. They are WK and WK There are several different test methods that help designers evaluate corrosion rates.

Leachable Chloride Content of Thermal Insulation

Preproduction corrosion test and 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.

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.

Print 1 2 3 4 5 page sstarting from page current page. The safe operation of oil refineries in the United States is under constant r 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. This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment.

So the insulation needs to be tight from moisture intrusion.

The values given in parentheses are mathematical conversions to SI units that are provided for x795 only c7955 are not considered standard. It is informational only and not an official part of the standard; the full text v795 the standard itself must be referred to for its use and application.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

The rates are compared to various astj solutions including DI water and 1-ppm and 5-ppm chloride solutions. Helps manufacturers ensure their chemical formulations help reduce the potential for CUI being caused by the insulation itself.
