If you are in the market for new pipe insulation, you may have considered nitrile rubber pipe insulation. There are two types of nitrile pipe insulation available, Class 0 and Class O. Here, we will discuss Class 0 and the advantages and disadvantages of each. To begin, let’s discuss Class 0 nitrile rubber pipe insulation. Its main advantage is its cost-effectiveness.
Class O nitrile rubber pipe insulation
NBR, or nitrile rubber, pipe insulation is made of an elastomeric foam that is characterized by a low thermal conductivity and excellent water vapor diffusion resistance. These properties enable it to prevent condensation, minimize energy losses, and protect against pipe frost. This pipe insulation is suitable for indoor and outdoor pipe applications, such as air conditioning and refrigeration units. Its flexible design and excellent fire resistance make it an ideal choice for ducts, heating systems, and refrigeration systems.
A Class O nitrile rubber pipe insulation consists of a closed cell elastomer material with an in-built water vapour barrier. This type of nitrile rubber pipe insulation is light and flexible, making it a good choice for a variety of applications, including plumbing, water ducts, and oil and gas pipelines. It also reduces energy costs, and is highly fire-resistant.
Eurobatex, a premium elastomeric foam, also known as Class O nitrile rubber pipe insulation, is manufactured by Union Foam SpA. It is available in sheets, coils, and unslit and self-sealing tubes in two-metre lengths. The company’s Class 0 nitrile rubber pipe insulation is the first of its kind to be certified to the new Euroclass fire ratings.
Another important factor to consider is corrosion. Water vapor in the environment is naturally drawn to cold surfaces, resulting in corrosion. This corrosion can cause a pipe to fail, so it is essential to choose the right thickness and seal it well. This way, water vapor cannot penetrate the pipe insulation system. A one-inch-thick pipe insulation can provide a temperature variance up to 40 degrees F. The thickness of the insulation is also a major consideration.
In the field of elastomeric pipe insulation, EPDM brand of closed-cell elastomeric foam offers excellent insulating properties. Its low k-value makes it an excellent choice for insulating austenitic stainless steel piping systems. Additionally, it is available with factory-fabricated fitting covers. It is also suitable for sealing longitudinal seams, pipe joints, and terminations.
Class 0 nitrile rubber pipe insulation
Nitrile rubber, also known as Buna-N, Perbunan, and NBR, is a synthetic rubber that is resistant to fuels and oil. Because of its closed cell structure, it also offers vapor barrier resistance. Its high degree of flexibility makes it a good choice for pipes that are exposed to extreme temperatures, such as in the air conditioning and refrigeration system. However, there are some disadvantages to this material.
Armaflex Class O Pipe Insulation is a closed cell nitrile rubber foam that provides excellent water vapor and thermal resistance. It prevents condensation and reduces energy losses, reducing costs. It also provides protection against corrosion and mould growth in pipes under insulation. Armaflex Class O pipe insulation is available in sheet and tube form. It is available in various thicknesses to meet the needs of a variety of applications.
Eurobatex, which manufactures Class 0 nitrile rubber pipe foam, is one of the first in the world to achieve CE Mark approval. Its performance meets the specifications laid out in EN 14304 for pipe insulation. It is dust and HCFC free, with zero Ozone Depletion Potential and Global Warming Potential. Eurobatex Class 0 pipe insulation also contains active Microbial resistance throughout its cell structure, making it an excellent choice for use in sterile environments and hospitals.
Another advantage of EPDM and Class 0 nitrile rubber pipe insulating foam is its low cost. It is also resistant to the effects of ultraviolet radiation, and a white UV coating protects it from corrosion. It also passes ASTM E84 25/50 flame spread index. It has a low VOC (volatile organic compound) content and meets the requirements of California Title 24.
Another important characteristic of closed cell elastomeric pipe insulation is its resistance to moisture. Its high resistance to moisture makes it a suitable choice for pipe insulation that contains austenitic stainless steel. It also meets USDA requirements for unexposed pipe insulation. Lastly, Aerocel elastomeric pipe insulation is UV resistant. Because it has a closed cell structure, it will degrade slower than other closed cell foam insulation types.
