What is PERT piping?
PERT piping is a type of plastic pipe used in a variety of applications, particularly in household and commercial plumbing systems. It is commonly used because of its flexibility, ease of installation, durability, and longevity.
History and development
The development of PERT piping began in the 1980s in Europe. It was first introduced to the market by a German manufacturer called Hoechst AG in 1982. Since then, it has become widely used in Europe and other parts of the world.
In the early 2000s, PERT piping was introduced to the United States. Initially, it was met with skepticism due to its lack of a track record in the US market, but its popularity quickly grew as contractors and homeowners realized its benefits.
What is PERT piping made of?
PERT piping is made of cross-linked polyethylene, a type of thermoplastic material. The cross-linking process involves adding a chemical cross-linking agent to the polyethylene, which creates a three-dimensional network of interconnected molecular chains.
The result is a material that is highly resistant to stress cracking, creep, and thermal degradation. PERT piping is also resistant to corrosion and chemicals, making it an ideal choice for use in harsh environments.
Advantages of PERT piping
Flexibility and ease of installation
One of the main advantages of PERT piping is its flexibility. It can be easily bent and curved to fit around obstacles, eliminating the need for fittings and reducing the risk of leaks. This also makes it easier to install, reducing labor costs and increasing efficiency.
Durability
PERT piping is highly resistant to stress cracking and creep, which means it can withstand high levels of stress and pressure. This makes it ideal for use in hot water and radiant heat applications, as well as in high-pressure plumbing systems.
Longevity
PERT piping has been proven to last for over 50 years, making it a long-lasting and reliable choice for plumbing and heating systems. Additionally, its resistance to corrosion and chemicals means it won''t deteriorate over time.
Eco-friendly
PERT piping is also eco-friendly, as it is made from recyclable materials. It is also energy-efficient, as it has low thermal conductivity, reducing heat loss in plumbing and heating systems.
Applications of PERT piping
PERT piping is used in a variety of applications, including:
Plumbing systems
PERT piping is commonly used in household and commercial plumbing systems, particularly in hot and cold water applications. It is also used in radiant heating systems, which use hot water to heat floors and other surfaces.
Industrial applications
PERT piping is also used in industrial applications, such as in chemical processing plants and power generation facilities. Its resistance to chemicals and high temperatures makes it well-suited for these types of applications.
Installation and maintenance
PERT piping is relatively easy to install, especially compared to traditional metal piping. It can be easily cut with a cutter or knife, and can be bent and curved to fit around obstacles. However, it is important to use the appropriate fittings and connectors to ensure a proper seal.
Maintenance of PERT piping is relatively minimal. Because it is resistant to corrosion and chemicals, it will not deteriorate over time. However, it is still important to keep an eye out for any leaks or damage that may occur due to external factors.
Safety concerns
While PERT piping is generally considered safe, there have been concerns raised about possible health risks associated with its use. Some studies have suggested that PERT piping may release harmful chemicals into the water supply, particularly when exposed to high temperatures.
However, the overall consensus in the industry is that PERT piping is safe for use in plumbing and heating systems. It is important, however, to use piping that is certified by industry standards organizations to ensure its safety and reliability.
Conclusion
PERT piping is a flexible, durable, long-lasting, and eco-friendly choice for a variety of plumbing and heating applications. Its ease of installation and low maintenance requirements make it an ideal choice for homeowners and contractors alike. While there have been some concerns raised about its safety, it is generally considered safe for use when installed according to industry standards.
