For corrosion to occur, three (3) elements are required: metal, air (oxygen) and water (electrolyte). Since metal and air are constant, the contributing factor to corrosion is the introduction of moisture. The corrosion process is accelerated with an insulated system when moisture becomes trapped between the insulation and metallic surface. This condition is known as corrosion under insulation (CUI)... Learn More --- ## The Purpose of Pipe Insulation URL: https://aeroflexusa.com/the-purpose-of-pipe-insulation/ The evolution of thermal insulation dates back to prehistoric times when people gathered natural materials to insulate their shelters and clothing. It was not until the industrial revolution of the early 20th century that artificial thermal insulation materials, like pipe insulation, were developed due to their favorable durability, fire and water resistance. The term insulate means to prevent the passage of heat, electricity, or sound by surrounding the area of concern with a non-conductive material. Thermal insulation prevents the transfer of heat because it is not a good conductor (non-conductive). There are many other technical aspects about the performance characteristics of thermal insulation, however, this post will focus on the purpose, reasons to insulate pipes, and insulation material selection.... --- ## Aerocoat® Premium Insulation Coating: Enhancing Performance and Protection URL: https://aeroflexusa.com/aerocoat-premium-insulation-coating-enhancing-performance-and-protection/ Introduction: Aeroflex USA is a leading manufacturer of AEROFLEX EPDM™ closed-cell elastomeric foam insulation and associated products.

URL: https://aeroflexusa.com/does-plastic-piping-need-to-be-insulated/ While well-known metallic piping types, such as copper and carbon steel, have been commercially available  for many years, plastic piping has rapidly grown in popularity as an alternative to metallic piping due to its performance and economic benefits. Depending on the plastic pipe type, plastic is approximately 25%-35% more thermally efficient than metallic  piping. What this means is that plastic possesses a lower thermal conductivity (K-Value) than metals and reduces heat transfer between the fluid in the pipe and the surrounding air. Depending on the plastic pipe type and application, the pipe may not need to be insulated. Some of the common plastic pipe types include Polyvinyl Chloride (PVC), Chlorinated Polyvinyl Chloride  (CPVC), Polypropylene (PP), Cross-Linked Polyethylene (PEX), Polyethylene (PE), Polyvinylidene Fluoride  (PVDF), Polybutylene (PB), and Acrylonitrile Butadiene Styrene (ABS).... --- ## Best AC Piping Insulation URL: https://aeroflexusa.com/best-ac-piping-insulation/ ## Overview of AC Pipe Insulation Air Conditioning (AC) pipe insulation plays a pivotal role in the efficiency and effectiveness of HVAC systems.

Learn More --- ## Freeze Protection of Pipes with Mechanical Pipe Insulation URL: https://aeroflexusa.com/freeze-protection-of-pipes-with-mechanical-pipe-insulation/ When pipes are exposed to freezing ambient temperatures, still fluids such as water will eventually freeze and cause system and property damage to the surrounding environment. While mechanical pipe insulation can buy time and prolong fluids in pipes from freezing, it will not prevent fluids from freezing in piping systems. For example, still water at 55ºF in a 6” IPS pipe insulated with 2” thick elastomeric insulation exposed to freezing temperatures of 0ºF will eventually freeze in approximately 23 hours. The length of time is determined by the variables noted above and the pipe insulation type. Insulation with lower thermal conductivity (K-value) will generally provide greater freeze protection. To provide long-term freeze protection, a heat trace cable is recommended to be installed on the pipe and below the insulation. It’s important to note that the heat trace cable selected should be self-regulating and not exceed the maximum operating temperature of the pipe insulation.... --- ## AEROFLEX® Sheet Insulation URL: https://aeroflexusa.com/aeroflex-sheet-insulation/ AEROFLEX® elastomeric Sheet and Roll insulation is a closed-cell, flexible insulation designed to insulate large-diameter pipes, pumps, tanks, vessels, spheres, and other mechanical equipment where pre-formed pipe insulation is not practical.

When TPS calsil or phenolic pipe supports are specified to be installed with AEROFLEX EPDM, the following procedures should be followed when sealing the two materials together at the circumferential seams: • Thoroughly clean and remove dust from sides of calsil and phenolic supports with denatured alcohol • Apply thin primer coat of Aeroseal or Aeroseal LVOC™... --- ## Understanding ASTM Standards: D1056, C534, and C795 URL: https://aeroflexusa.com/understanding-astm-standards-d1056-c534-and-c795/ In the realm of industrial materials and applications, adherence to recognized standards is crucial for quality, safety, and efficiency. ASTM International standards are globally acknowledged benchmarks in this regard. This blog post will explore three specific ASTM standards: D1056, C534, and C795, each serving unique roles in their respective domains. ## ASTM D1056: For Flexible Cellular Materials ### Overview of ASTM D1056 ASTM D1056 specifies standards for flexible cellular materials, such as sponge or expanded rubber, excluding latex foam rubber and ebonite cellular rubber. These materials are widely used in automotive applications, weather stripping, and various padding in industrial and consumer products. ### Applications and Importance Such materials are integral in numerous industries due to their flexibility, durability, and environmental resistance. To understand more about how these materials are used in practical applications, visit our product codes page.... --- ## Nesting Chart (Copper) for AEROFLEX EPDM™ Pipe Insulation URL: https://aeroflexusa.com/nesting-chart-copper-for-aeroflex-epdm-pipe-insulation/ Certain HVAC, refrigeration and plumbing pipe insulation applications require more than a single layer of AEROFLEX EPDM ™  flexible elastomeric insulation to control condensation in demanding conditions such as a cold line temperature in a hot and humid operating environment. Our “nesting” chart offers the best fit for installing an additional layer (sleeving) over the most common  copper  and  iron  pipe insulation sizes. It’s important to note that Aeroflex USA tests 1”, 1-1/2” and 2” thicknesses for ASTM E84 25/50 flame/smoke compliance. We do not test other thickness combinations, and thicknesses over 2” will not pass ASTM E84.

Mechanical insulation for piping, ductwork, and equipment is no exception. Standard specifications have been established by ASTM for mechanical insulation products and accessories, such as adhesives, tapes, jackets, sealants and coatings. Specifications are broken out into sections such as classifications, materials, physical requirements, standard shapes, sizes, and dimensions, surfaces, workmanship, finish, and appearance, sampling, test methods, inspection, rejection, packaging and marking, and keywords. ASTM standards are also periodically revised/updated with the year as a suffix (i.e. ASTM C534-25).... --- ## Brand Name Change from Aerocel® to AEROFLEX® URL: https://aeroflexusa.com/brand-name-change-from-aerocel-to-aeroflex/ Aeroflex USA renamed our EPDM closed-cell elastomeric insulation brand name from Aerocel® to AEROFLEX® in February 2023. While Aerocel data sheets and packaging continue to exist in the marketplace, there is no change to the product itself. AEROFLEX and AEROFLEX EPDM™ branded products consist of the same EPDM formulation as Aerocel. In other words, this is a change in name only. Below is a product name cross reference by AEROFLEX product line: --- ## Duct Insulation Adhesives URL: https://aeroflexusa.com/duct-insulation-adhesives/ For lining and wrapping sheet metal ductwork, Aeroflex USA offers AEROFLEX Aeroseal , REF 1520™ , and Aeroseal LVOC™ adhesives for the installation of AEROFLEX Breathe-EZ™ EPDM Duct Insulation . Aeroflex USA does not offer an aerosolized spray adhesive for the installation of AEROFLEX Breathe-EZ™. We recommend that duct fabricators and insulators check with preferred adhesive manufacturers for their recommended spray adhesives to line and wrap ductwork with closed-cell elastomeric foam. Care must be taken when selecting an aerosolized spray contact adhesive to bond closed-cell elastomeric foam duct insulation to sheet metal ductwork. Water-based adhesives utilized to install fiberglass and other open-cell duct insulation types will not perform as intended with closed-cell duct insulation.... --- ## ASTM E84 25/50-Explained for Mechanical Insulation Applications URL: https://aeroflexusa.com/astm-e84-25-50-aeroflex-usa/ ASTM E84 25/50 is an important fire safety standard developed to protect the lives of building occupants. It appears frequently in mechanical insulation project specifications and is commonly adopted by authorities having jurisdiction (AHJ’s) for commercial and residential building codes.   For engineers, contractors, and owners, understanding ASTM E84 25/50 is essential to ensuring materials meet code requirements and are suitable for use in plenums, duct systems, and mechanical piping.   Another commonly referenced fire safety standard is the UL 723 (UL Solutions) rating , which is often considered a reciprocal standard that uses almost exactly the same test method by two separate standard and test method organizations. To learn more about how the two compare, you can read more in this article . ## What Does ASTM E84 25/50 Mean?... --- ## The Important of a Perm Rating URL: https://aeroflexusa.com/the-important-of-a-perm-rating/ An often overlooked technical performance characteristic of mechanical pipe and equipment insulation is water vapor permeability (WVP). ASTM International defines WVP as “the time rate of water vapor transmission through unit area of flat material of unit thickness induced by unit vapor pressure difference between two specific surfaces, under specified temperature and humidity conditions." A primary purpose of mechanical insulation on below-ambient (low-temperature) pipe & equipment systems, such as chilled water and refrigeration, is to prevent heat gain, control condensation, and minimize the risk for corrosion under insulation (CUI). Water vapor will naturally attempt to drive through insulation to the cold pipe surface. This phenomenon is also known as “vapor drive”. The ability of an insulation material to resist water vapor transmission is reported as a “perm rating” in Inch-Pound (English) or SI (International) units. For example, English perm ratings are published as 0.... --- ## Redesigned AEROFLEX EPDM™ Tube Cartons URL: https://aeroflexusa.com/redesigned-aeroflex-epdm-tube-cartons/ Aeroflex USA recently announced redesigned graphics for our Standard Unslit and Self-Seal tube cartons. An important aspect of this redesign was to better communicate to our customers how to successfully “knock out” the perforations on both ends of the box. The intent of our easy-open box ends is to facilitate quick access to insulation tubes while avoiding unsightly flaps and unnecessary labor to completely cut off box-end flaps. Below is a recent announcement to our customers that includes a brief video about how to successfully knock out the perforations at the easy openings. Just scan the QR Code in the bottom right. --- ## Heat Trace Systems with AEROFLEX® EPDM™ Closed Cell Elastomeric Insulation URL: https://aeroflexusa.com/heat-trace-systems-with-aeroflex-epdm-closed-cell-elastomeric-insulation/ With frigid arctic winter blasts on the increase in the United States, property damage caused by frozen pipes runs into the hundreds of millions of dollars. Property owners and property insurance owners are negatively impacted. In December 2022, cities such as Jackson, MS and Chaleston, SC experienced record-low temperatures, pipe bursts, and boil-water advisories. In general, pipes are subjected to freezing at ambient temperatures of 20°F or below. When standing water freezes in a pipe, it expands and causes the pipe to burst and ultimately leak. Pipe leaks also result in reduced water pressure to water municipalities and districts. For residential home and commercial building owners, frozen pipes can result in significant damage to interior building components and equipment. The cost of operational downtime in a commercial or industrial environment cannot be overlooked.... ---
