RPAP5 butt welding aluminum-plastic composite pipe product characteristics

RPAP5 butt-welded aluminum-plastic pipes are mainly used in high-end home improvement high-temperature radiator heating, solar water heaters and other high-temperature hot water pipes to meet the needs of high safety, high stability and high quality for water supply and heating pipes. The long-term working temperature is 95°C. , Long-term working pressure of 1.25MPa is the only composite pipe in China that meets the requirements of 95°C high temperature hot water pipes, and it is also the safest composite pipe in the field of high temperature hot water pipes. Especially suitable for high-end home improvement villa risers and other fields.

　　 1. Product features

　　High safety aluminum-plastic composite pipe

　　 1. More advanced performance

RPAP5 butt-welded aluminum-plastic composite pipe inner and outer plastic layers use advanced PE-RT pipe materials from South Korea’s LG company. Under the same use level, the allowable stress of South Korean LG’s PE-RT pipe special materials is higher than that of PEX. Allowable stress, therefore, the performance of Vispert RPAP5 pipe is better than XPAP2 pipe.

　　2, the connection is more reliable

　　Pipe, pipe fittings use the same material, using double hot-melt connection method, the joints of pipes and pipe fittings are melted into one body, and the joints have high strength, hot-melt connection, and never leak. It effectively solves the problem of easy leakage at the joints of ordinary aluminum-plastic pipes due to different pipe materials and pipe fittings.

　　3, safer to use

　　According to the American ASTMF1335-1998 standard:

　　 Butt-welded aluminum-plastic composite pipe is a metal pipe with a plastic protective layer.

　　Lap welded aluminum-plastic composite pipe is a plastic pipe with a metal shielding layer.

　　 RPAP5 butt-welded aluminum-plastic composite pipe aluminum layer wall thickness, aluminum layer as the main pressure layer, using advanced laser butt welding, the aluminum pipe is completely enclosed, high strength, and the pipeline system is safer.

　　The aluminum layer of the lap welded aluminum-plastic composite pipe is thinner, the aluminum layer adopts ultrasonic lap technology, and the plastic layer is the main pressure-bearing layer.

　　 as shown:

　　 2. Application areas

　　The safest plastic composite pipe for radiator heating

　　At present, the only composite pipe in China that meets 95°C and 1.25MPa service conditions

1. The long-term use temperature of RPAP5 butt welded aluminum-plastic composite pipe is 95°C, and the allowable working pressure is 1.25MPa, which can fully ensure the stability and safety of the system. It is the safest pipe for hot water and heating fields such as high temperature radiators and solar water heaters. .

　　 2. High-safety and high-quality pipelines for building water supply and heating.

　　 Three, connection method

　　 hot melt connection never leaks

　　1, double hot melt connection

RPAP5 aluminum-plastic composite pipe fittings are produced using special materials for PE-RT pipe from South Korea’s LG company, which are the same as the plastic layer of the pipe; the pipe fitting welding port is a double-layer ring-wall structure socket, which is respectively welded to the inner and outer layers of the pipe; the socket is built-in Bushing, when welding, the bushing has a supporting effect on the inner wall, so that the pipe and the pipe fittings are well fused and connected together, the connection is firm, no leakage, no corrosion, and high strength. It is the aluminum-plastic composite pipe connection technology and method Innovation and breakthrough.

　　2, features

　　A The connection is firm-the double-layer heat-deep connection of national materials, never leaks.

The socket of the pipe fitting is hot-melt connected with the inner and outer layers of the pipe, the pipe and the pipe fitting are integrated, and the strength of the joint is higher than that of the pipe itself.

　　B Fast installation-improve construction efficiency

Only need a full circle, no chamfering, fast installation speed, high pass rate of one installation

　　C joints can be buried in the dark-flexible construction plan

The hot-melt joint is safe and reliable, and can be buried in the wall and floor filling layer, which is convenient for the design and installation of the pipeline system
