It fits 2-1\/2 inch IPS pipe with a 2-7\/8 inch inside diameter and a 1\/2 inch wall thickness. Each section is 6 feet long. The closed-cell foam construction provides an R-value of 3.2 and a water vapor permeability of 0.08 perm-in, effectively resisting moisture migration and condensation formation on pipe surfaces. Licensed HVAC technicians, pipefitters, and mechanical insulation contractors install this product on chilled water, refrigeration, and hot and cold water piping systems.\u003c\/p\u003e\u003cp\u003eThis pipe cover is suited for a wide range of mechanical piping applications including refrigeration lines, chilled water systems, hot and cold water piping, HVAC air plenums, exposed ceilings, and exterior piping. It is commonly specified in schools, universities, hospitals, government buildings, and commercial facilities where long-term thermal performance and condensation control are required. Its temperature rating of -297 to 220 degrees F makes it appropriate for both low-temperature refrigeration lines and standard HVAC piping in demanding environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClosed-cell elastomeric foam resists moisture absorption at 0.2 percent water absorption\u003c\/li\u003e\n\u003cli\u003eR-value of 3.2 for effective thermal insulation at 1\/2 inch wall thickness\u003c\/li\u003e\n\u003cli\u003eTemperature rating of -297 to 220 degrees F for refrigeration and HVAC service\u003c\/li\u003e\n\u003cli\u003eFlame Spread Index of 25 and Smoke Developed Index of 50 for code-sensitive installations\u003c\/li\u003e\n\u003cli\u003eThermal conductivity of 0.235 to 0.268 Btu-in\/hr-sq-ft-degrees F\u003c\/li\u003e\n\u003cli\u003eDomestic manufacture\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 2-1\/2 inch IPS pipe with a 2-7\/8 inch outside diameter.

Depressurize and drain or isolate the pipe section before applying insulation in service situations. Seams and butt joints should be sealed per the manufacturer and project specification requirements to maintain vapor barrier integrity. Do not compress the foam wall beyond the rated thickness, as this reduces the effective R-value and thermal performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIron Pipe Size\u003c\/strong\u003e: 2-1\/2 inches IPS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall Thickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 6 ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eR-Value\u003c\/strong\u003e: R3.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -297 to 220 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Conductivity\u003c\/strong\u003e: 0.235 to 0.268 Btu-in\/hr-sq-ft-degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Vapor Permeability\u003c\/strong\u003e: 0.08 perm-in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Absorption\u003c\/strong\u003e: 0.2 percent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlame Spread Index\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmoke Developed Index\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Elastomeric Foam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Closed Cell\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity\u003c\/strong\u003e: 3 to 6 cu-ft\/lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Armacell\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ARMA-APT21012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARMACELL","offers":[{"title":"Default Title","offer_id":51524331241778,"sku":"ARMA-APT21012","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f8fe09f948f7559872c92611779ab83.jpg?v=1785446209","url":"https:\/\/voomisupply.com\/products\/armacell-arma-apt21012-ap-armaflex-pipe-cover-2-5-in-ips","provider":"Voomi Supply","version":"1.0","type":"link"}
