What Is CPVC Piping Used For?
CPVC piping is used in the manufacturing of many products. It is mainly used for water supply systems, plumbing fixtures and appliances. CPVC pipes are commonly found in homes, offices and factories. They are usually made from PVC (polyvinyl chloride), but they can also be made from other materials such as ABS (acrylonitrile styrene) or PETE (Polyethylene terephthalate).
CPVC Pipe Types
There are two main types of CPVC pipes: polypropylene and acrylic. Polypropylene is generally considered safer than its plastic counterparts because it does not contain phthalates, which may cause reproductive harm when inhaled. However, they do have their drawbacks too. They tend to crack easily and break down over time due to exposure to moisture and sunlight. Acrylic, on the other hand, may be less prone to breaking down over time, but they can also easily become damaged.
Both types of pipes may be used to carry different types of substances around a building. The different types of piping are summarized in the following table:
Pipe Size (Inches) Outside Diameter (Inches) O.D.

How Are They Used?
The most common use for these pipes is to transport liquids and gases around a building. These can range from water and sewage around a building to natural gas in some commercial or industrial buildings. In some instances, steam is also transported through these pipes.
They can also be used to transport materials such as foams, oils, and greases. For example, they may be used to transport cooking oils and other fluids that need to be cooked in a factory.
Other materials that may be transported through these pipes include:
Liquids such as water or fuels
Gases such as air or natural gas
Plasma in fluorescent lamp tubes
What Are The Advantages Of Using These Pipes?
There are quite a few advantages of using these pipes in a building. Some of these advantages include:
They are easy to use and maintain.
They are strong and durable.
They can be used inside or outside a building.
They can be used to transport a number of different materials.
What Are The Disadvantages Of Using These Pipes?
Despite their many advantages, there are some things that might be regarded as disadvantages of using these pipes. Some of these disadvantages include:
The larger the pipe, the more expensive it is to run through a building.
They cannot be used underwater.
They cannot be used for very hot items or those that need quick reactions, such as nuclear fuel (although this is becoming less of an issue, as these pipes are being less widely used nowadays).
