Ⅰ. Product Overview

The raw material for this floor heating is a medium-density polyethylene with extremely stable mechanical properties, which is copolymerized from the monomers of ethylene and octene through metallocene catalysis. Its unique ethylene main chain and octene short side chain structure endow it with the superior toughness, stress crack resistance, low-temperature impact resistance, outstanding long-term water pressure resistance of ethylene and the thermal creep resistance of octene simultaneously.

The PE-RT raw material not only has a qualified creep rupture curve, but also has a moderate pipe price. Its construction is relatively convenient and fast compared to other varieties. The connection form belongs to the most reliable in-situ mutual fusion hot-melt connection form at present. The hole diameter of the pipe fitting part is larger than the inner diameter of the pipe of the same specification. In the system, there is no mechanical connection method with local diameter reduction. Therefore, the fluid resistance of the system is relatively small.

With the development of plastic technology, indoor heating systems can provide various plastic pipes for different purposes. Plastic pipes have the advantages of smooth inner walls, low resistance to heat medium flow, acid and alkali resistance, long service life and easy installation. In recent years, PE-RT has been widely used in floor heating systems. As a new generation of dedicated heating pipe materials, it is gradually becoming the mainstream product in the floor heating market.

1. Basic Info

Ⅱ. Product Feature

1. Flexibility: PE-RT pipes, due to their soft material and excellent flexibility, demonstrate remarkable construction convenience and economy during the laying process. This type of pipe can be transported and stored by coiling and directly bent and laid on site, without the frequent use of elbows, joints and other pipe fittings, thus significantly reducing the amount of accessories used. During the construction process, there is no need to rely on special tools or complex equipment. Ordinary operations can complete cutting, bending and connection, effectively reducing labor and equipment costs. In addition, its simple processing method also shortens the installation time, reduces the complexity of the project, and optimizes the overall cost in multiple aspects such as material conservation, time compression and tool simplification.

2. Thermal Conductivity: PE-RT pipes, with their outstanding flexibility and thermal conductivity, have become the ideal choice for floor heating systems. Its excellent flexibility enables the pipes to be transported by coiling and laid directly by bending, significantly reducing the usage of pipe fittings. Moreover, construction does not require special tools, significantly lowering material, labor and overall costs. Meanwhile, PE-RT pipes have a thermal conductivity of approximately 0.4 W/(m·K), which is about twice that of common plastic pipes such as PP-R and PP-B. They can quickly and evenly conduct heat to the ground, thereby enhancing the system's response speed, temperature control accuracy, and heating uniformity. This also helps achieve efficient operation at low temperatures and reduce long-term energy consumption. These characteristics collectively make PE-RT pipes economically viable, easy to install and highly efficient in floor heating applications.

3. Low-Temperature Thermal Shock Resistance: PE-RT pipes stand out particularly in terms of low-temperature resistance, giving them a significant advantage in construction and application in cold environments. This pipe material can still maintain excellent impact toughness under low-temperature conditions. It is less likely to break due to brittleness during winter construction. This not only reduces the risk of material loss but also greatly increases the flexibility of construction arrangements, allowing the project to proceed as usual even in the coldest seasons. In addition, its flexibility at low temperatures remains excellent, and there is no need to preheat the pipes during bending operations, further simplifying on-site procedures and enhancing construction efficiency. In terms of long-term durability, PE-RT pipes also perform exceptionally well. Under typical operating conditions of a continuous working temperature of 70℃ and a pressure of 0.4MPa, its designed service life can exceed 50 years. This is attributed to the stability of its molecular structure and its heat aging resistance, which can ensure that the pipeline maintains its strength and sealing performance during the long-term operation of the heating system, providing users with reliable and long-lasting system protection. Therefore, whether in terms of construction adaptability or long-term service performance, PE-RT pipes are a reliable preferred material in low-temperature environments and heating systems.

4. Environmental Friendliness: PE-RT pipes are a type of high-performance pipe that integrates environmental protection, durability and health safety. Its production does not require toxic additives, and the materials are recyclable, making it environmentally friendly. The pipe has excellent chemical corrosion resistance and low-temperature impact resistance, a long service life, and is easy to install. Especially in winter, it can still operate flexibly. Meanwhile, its inner wall is smooth and never scales, which can effectively inhibit the growth of bacteria, ensure the cleanliness of the delivered water, and fully meet the safety standards of the drinking water system.

5. Processing Performance Stability: PE-RT pipes are easy to process and can be formed mainly through standard extrusion processes. Its core properties (such as heat resistance and flexibility) are determined by the molecular structure of the raw materials themselves. Therefore, as long as qualified raw materials are selected, the performance of the produced pipes will be highly stable and reliable, with small differences between batches and easy quality control.

Ⅲ. Application Field 

PE-RT pipe is a widely used high-performance plastic pipe. Its core advantages lie in its outstanding flexibility, long-term heat and pressure resistance, excellent thermal conductivity and environmental safety characteristics. It is mainly applied to the HVAC and water supply systems inside buildings, specifically including:

1. Heating Applications: It is the preferred pipe material for floor radiant heating and is also suitable for the connecting pipes of radiator heating systems.

2. Water supply field: Widely used in the cold and hot water supply and direct drinking water delivery systems of buildings.

3. Special fluid transportation: Due to its hygiene and corrosion resistance, it is also applied in fields such as the food industry, agricultural irrigation, hot springs, and solar hot water systems.

4. Refrigeration system: It can be used for the transportation pipelines of low-temperature fluids such as air conditioning cooling water
