|Thermal Insulation Committee Developing New Standard on Pipe-Covering Products
Committee C16 on Thermal Insulation is currently working on a new standard that deals with several new pipe-covering products in an insulation system developed for the U.S. Navy. It was originally proposed that the new products, which are called Solrex®, be included in the current ASTM specification C 1482. However, members of the Subcommittee C16.22 on Organic and Non-Homogenous Inorganic Thermal Insulations determined that it would be best to create a new standard for pipe-covering products, as well as other polyimide materials.
The U.S. Navy is doing a land trial on the pipe covering and has recently installed it in a destroyer to undergo a sea trial evaluation. Plans are also under way to conduct a trial installation on a U.S. Navy carrier. Once the Navy has approved the system, it will consider the use of this new standard to specify the product for its fleet.
In addition to its use by the U.S. Navy, the other purpose of the new polyimide standard will be to present a basic set of polyimide foam properties for a diverse range of product applications. Scott Snider, R&D manager, Inspec Foams, Inc., says that new types and grades of polyimide foam materials will be added to the standard as test data on them are submitted.
Polyimide foams are, when compared to most other organic foams, extremely thermally stable and very low in both flammability and toxic gas generation when combusted, says Snider.

Committee C16 on Thermal Insulation meets Oct. 3-6 during the October Committee Week in Washington, D.C.
