Considerations to Prevent External Stress Corrosion Cracking with Austenitic Stainless Steel

One of the greatest threats, sources of system failure, and maintenance/replacement costs
to mechanical systems is corrosion to the metallic surfaces of piping and equipment.

What to Look for in HVAC Refrigerant Pipe Insulation

What to Look for in HVAC Refrigerant Pipe Insulation

HVAC refrigerant pipe insulation is a critical component to a well-designed refrigeration system to achieve long-term performance and life cycle costs for building owners. Refrigeration systems are demanding and generally operate continuously with the potential for downtime to be minimized. While every refrigeration system has its own set of unique requirements, they all have two…

Specifying UV-Resistant Refrigerant Line Insulation

Specifying UV-Resistant Refrigerant Line Insulation

Refrigerant piping must often be installed in building exteriors, such as rooftops, to convey refrigerants between large roof-top HVAC systems and interior equipment to provide conditioned air to the building’s occupant spaces and equipment. U.S. commercial energy codes and standards, such as ASHRAE 90.1 Energy Standard for Buildings Except for Low-Rise Residential Buildings, International Energy…

How to Choose the Best Plenum-Rated Pipe and Duct Insulation

How to Choose the Best Plenum-Rated Pipe and Duct Insulation

Plenum spaces in buildings are designed to discreetly house building systems such as HVAC equipment & return airflow, pipe runs, and digital cables. Although air plenums are typically out-of-sight, typically located above ceiling grids or in under-floor systems, mechanical design and plenum-rated pipe and duct insulation are critically important to ensure the safety of building…

Pipe Hanger Supports Critical to High-Performance Insulation System Design

Pipe Hanger Supports Critical to High-Performance Insulation System Design

A common failure point of mechanical insulation on cold (below-ambient) piping systems is
at the hanger locations due to compression of insulation subjected to inadequate support
or no insulation at all (thermal bridging)

Nesting (Layering) Chart for Aerocel® Pipe Insulation

Nesting (Layering) Chart for Aerocel® Pipe Insulation

Certain HVAC, refrigeration and plumbing pipe insulation applications require more than a single layer of Aerocel® 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.

Key Considerations for Refrigeration Pipe Insulation

Key Considerations for Refrigeration Pipe Insulation

Refrigeration pipe insulation is crucial for refrigeration systems. Refrigeration systems, also known as below-ambient systems, vary by application (commercial and industrial), temperature requirements (high & low), refrigerant types (traditional and natural) and operating environments. Common refrigeration system applications include supermarkets, cold storage, food processing, beverage dispensing lines, ice rinks, morgues, laboratories, chillers, data centers and…

A Proven Solution for Hydronic Pump Insulation

A Proven Solution for Hydronic Pump Insulation

Looking for a solution for hydronic pump insulation? Let’s start with hydronic pumps. Hydronic heating and cooling systems circulate water through a building’s piping systems to deliver heating and cooling for occupant comfort. These systems are basically composed of an energy source, such as a boiler, water heater or chiller, and electronically-powered pumps that move…

Guide to Mold Resistant Insulation

Guide to Mold Resistant Insulation

Mold resistant insulation is an important consideration to prevent the dangers of mold. Molds belong to the fungi kingdom, and unlike plants, they lack chlorophyll and must survive by digesting plants and other organic materials. Molds generate tiny spores to reproduce, and these spores are ever-present in both indoor and outdoor air currents. When mold…

Why Use Plumbing Pipe Insulation?

Why Use Plumbing Pipe Insulation?

Wondering why to use plumbing pipe insulation? Plumbing piping systems, commonly known as domestic hot and cold water service systems, convey water to fixtures and equipment for various purposes in residential, commercial and industrial buildings.    The most common concerns with plumbing systems that should be addressed during the design stage include heat loss, condensation…
