PE-RT water supply pipe
PE-RT pipe, or Polyethylene of Raised Temperature Resistance pipe, is a relatively new type of plastic pipe. Its unique molecular structure gives it excellent performance at elevated temperatures. It has become a popular choice for modern water supply systems due to its advantages of flexibility, durability, and resistance to corrosion.
PE-RT pipes are typically manufactured from a specialized polyethylene resin. The polymer chains in PE-RT are arranged in a way that enhances the material's thermal stability and mechanical strength without requiring cross-linking processes.
Production Process
The production of PE-RT pipes involves several steps. First, high-quality polyethylene resin is selected as the raw material. Additives may be incorporated to enhance the pipe's properties, such as UV stabilizers and colorants. The resin is then heated and melted in an extruder. The molten material is forced through a die to form the desired pipe shape. After extrusion, the pipe is cooled and solidified, usually through water baths or air cooling. Finally, the pipe is cut into specified lengths.
Advantages
PE-RT pipes have excellent thermal stability and can withstand long-term pressure. They can be safely used for over 50 years under a working temperature of 70℃ and a pressure of 0.4Mpa. This makes them suitable for both hot and cold water applications.
They have a high degree of flexibility, which makes installation easier and more economical. Their small bending radius (Rn=5D) and lack of rebound after bending make them ideal for construction usage. The stress on bending parts is quickly relaxed, avoiding damage caused by stress concentration.
PE-RT pipes have excellent impact resistance and high security. Their low-temperature brittleness temperature is -70℃, allowing them to be transported and constructed in low-temperature environments. Their ability to resist external forces is much higher than other pipes, and they do not need to be heated to bend.
PE-RT pipes have a dual effect of UV-light resistance and oxygen barrier. This protects the pipes from degradation due to sunlight exposure and prevents oxygen ingress, which can corrode boilers and other system components.
The pipes can be joined using heat fusion techniques, making installation and repair convenient, fast, and safe. If the system is damaged due to external forces, repairs can be easily made using heat fusion.
PE-RT pipes can be produced without crosslinking processes. This results in fewer production steps and a more uniform wall thickness.
They have good chemical resistance and are resistant to a wide range of chemicals, making them suitable for various plumbing and industrial applications.
PE-RT pipes are non-toxic, odorless, and have no pollution to water quality, meeting environmental protection requirements. They help maintain the cleanliness and hygiene of the water supply.
Applications
PE-RT pipes are widely used in various fields. In residential and commercial plumbing systems, they are used for hot and cold water distribution, radiant floor heating, and HVAC systems. They are also used in industrial and commercial applications, such as factory production line water supply systems and large commercial facility water supply networks. Additionally, PE-RT pipes are used in agricultural irrigation systems, where their corrosion resistance helps ensure the cleanliness and safety of irrigation water.
Market Prospects
With the continuous development of the plumbing and heating industries, the demand for efficient, durable, and sustainable piping materials is increasing. PE-RT pipes, with their excellent performance and broad application range, are expected to play a significant role in modern infrastructure. Their adoption is likely to continue growing as professionals and homeowners seek innovative and reliable piping solutions.
In summary, PE-RT water supply pipes are an ideal choice for modern water supply systems. Their excellent thermal stability, flexibility, durability, and resistance to corrosion make them suitable for a wide range of applications. As the market for piping materials continues to evolve, PE-RT pipes are poised to become an increasingly important component of modern plumbing and heating systems.
