Floor heating pipe

pert floor heating pipe

 PE-RT is heat-resistant polyethylene.

PE-RT is the abbreviation of Polyethylene of raised temperature resistance . It is a non-cross-linked polyethylene that can be used for hot water pipes, also known as ” high temperature resistant non-cross-linked polyethylene ” . It is a medium-density polyethylene produced by special molecular design and synthesis process, which improves the heat resistance of PE . It retains the good flexibility, high thermal conductivity and inertness of PE , while making it more pressure-resistant. PE-RT pipes can be used for all use levels of hot water pipes specified in ISO10508 .

Product Introduction

PE-RT pipes and fittings are high-temperature resistant pipe systems produced in accordance with CJ/T175-2002 using ethylene – octene copolymer as the main raw material . The raw materials used have a unique molecular structure and good water pressure resistance. It has particularly good softness, is easy to bend without deformation during construction, has outstanding low-temperature impact resistance , is safe and hygienic, has hot-melt connection, reliable interface and never leaks. It is an ideal pipe for low-temperature hot water floor radiant heating .

Low-temperature hot water floor radiant heating is an ideal heating method. It uses low-temperature hot water as a heat medium, heats the floor through plastic pipes buried in the floor, and radiates heat evenly into the room. It is an energy-saving heating system that regulates the room’s microclimate.

Low-temperature hot water floor radiant heating successfully solves the problem of heat source tension in high-space, large-span, and low-window buildings, improves heating comfort, and gives people a comfortable feeling of warm feet and cool head , which is in line with the physiological regulation of the human body. Features: It promotes blood circulation in the human body, while also reducing floor noise, realizing automatic temperature control for households and rooms, eliminating dust and odors in cooling equipment, and has a service life of more than 50 years.

PE-RT floor heating pipe >> Performance characteristics

1. Light weight, easy to transport and install.
   2.Good flexibility, making it convenient and economical to lay. Recyclable and meets environmental requirements;
   3. When the pipe is bent, the stress in the bent part can be relaxed quickly without ” rebound ” phenomenon, which facilitates construction operations and avoids bending of the pipe due to stress concentration during use. The phenomenon of damage occurs at various places;
   4. The friction loss in the pipe is small, and the fluid transport capacity of the pipe is 10% greater than that of the PE-X pipe of the same diameter ; 5. The brittle temperature is low, and the pipe has excellent low-temperature properties, so it can be used under low temperature conditions in winter It can also be constructed, and no preheating is required when bending the pipe, which can solve the economic losses caused by the low winter temperature in northern and the inability to construct. The minimum bending radius is 5 times the outer diameter of the pipe; 6. Chemical resistance Good corrosion resistance, no rust, long service life. After several years of use of general steel pipes, the inner wall of the pipe becomes rough due to severe corrosion, and the flow resistance increases, thereby greatly reducing the water transport capacity; 8. Under the conditions of an operating temperature of 70°C and a pressure of 0.82MPa , the pipe can be used safely for 50 years. Above; 9. No toxic additives are added to the pipe during the production process. The inner wall is smooth, does not scale, does not breed bacteria, and can be safely used in drinking water transportation and other fields; 10. The impact resistance is 2nd of that of PE-X pipes times ; 11. Good heat dissipation performance, thermal conductivity is 0.4 W/ ( m·K ), which can save a lot of energy in heating applications, so the use of PE-RT in the heating field can better exert its excellent characteristics; 12. Weldability : After the system pipeline is damaged, it can be repaired by socket hot fusion welding or electric fusion welding.

Application areas of PE-RT floor heating pipes : floor heating systems. It is suitable for heating in family living rooms, bedrooms, public baths, swimming pools, kindergartens, nurseries, nursing homes, etc. It is also suitable for other special needs; building hot and cold water supply, pipe drinking Water system; fluid transportation pipelines for beverages, alcohol, milk and other fluids in the food industry. 

Introduction to other aspects of PE-RT pipe

1. Classification:
   1) Common specifications classified by pipe diameter: dn10 , 25 , 32 , 40 , 50 , 63 , 75 , 90 , 110 , 125 , 140 , 160 , 180 , 200 , 225 , 250. Standard length: 4000 , 6000 ( mm ) can be customized according to demand. 2 ) According to the pipe system ( S ), commonly used ones are divided into S3.2 , S4 , S5 , S6.3 . 3 ) According to the pipe connection method, there are three categories: hot melt connectors, electric fusion connectors and mechanical connectors. ① Hot melt connectors, hot melt butt pipe fittings, dn≥63 ; hot melt socket fittings , dn32-dn160 . ②Electric fusion connection fittingsElectric fusion socket fittings DN20-DN160 . ③Socket flexible connection fittings DN20-DN160 . 2. Key points for design selection: 1 ) Engineering design should comply with relevant national design standards, specifications and regulations. 2 ) General procedure: The selection of heat-resistant polyethylene water supply pipes should be based on the requirements of the pipeline laying environment and the temperature of the conveying medium to determine the allowable bearing pressure and use condition level. The wall thickness of the pipeline system should be selected from the relevant standards, and the system pipe diameter should be selected according to the hydraulic calculation. In combination with the system layout, laying method, connection form, technical measures to compensate for temperature changes, etc., select products whose quality meets the current national relevant product standards. 3 ) Main application occasions: indoor cold and hot water pipes, especially hot water systems. 3. Key points for construction and installation: 1 ) The buried pipes below the indoor floor should be re-excavated after the backfill soil of the civil engineering project is compacted. It shall not be buried before the backfill soil or on the uncompacted soil layer. 2 ) Pipeline connection methods require that pipes and pipes, or pipes and fittings of the same brand and material be connected.
