The material shall conform to the established requirements of the basic material specification. As long as a given product meets the insulation-specific minimum requirements, it can be considered an eligible material to bid on the project. Generic material standards are often specified by engineers to ensure competition and not show favoritism to one manufacturer or another.
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 c7795 confirming quality control, chemical requirements, when tested in accordance with the Test Methods C 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.
The physical and chemical requirements shall conform to the requirements of the basic material specification.
The rates are compared to various control solutions including DI water and 1-ppm and 5-ppm chloride solutions. C7795 what confuses me is that does the claim of this manufacturers possibly real and is the required specification of not less than 5ppm attainable? The insulation industry must lead the way in helping designers and axtm owners directly face the costly battle against CUI. This abstract is a brief summary of the referenced standard.
The following is a list of brief explanations of 4 commonly specified corrosion ASTM material standards and test methods. As these standards frequently take extensive amounts of time to gain consensus within each committee, the absence of a particular test method should not call into question the corrosion performance of any insulation standards that do not yet reference the test.
Most manufacturers claim less than 10ppm others ppm. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Unfortunately, CUI can be very difficult to detect, often only being discovered after it has caused significant damage.
They are WK and WK 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. Register for a trial account.
Understanding ASTM Test Methods Evaluating Thermal Insulations and Corrosion of Metals
If you like to setup a quick demo, let us know at support madcad. 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. January 30, – February 2, Where: 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.

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.

This specification covers non-metallic thermal insulation for use in contact with austenitic stainless steel piping and equipment. This would be a great way to increase credibility of the industry, help lower energy costs, and reduce CUI potential within affected systems.

One must take the time to read the actual material standard to atm what the passing criteria are because, as noted above, they can vary from one material standard to another. 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 zstm 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.
The most predictable and cost-effective method to manage CUI is a systematic inspection program. 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.
