Co to jest rura kompozytowa aluminiowo-plastikowa PPR?

Rura kompozytowa aluminiowo-plastikowa PPR nazywana jest rurą aluminiowo-plastikową (PAPKA). Jest to rura kompozytowa, której warstwą wewnętrzną i zewnętrzną jest polietylen, a środkowa warstwa rdzenia jest przełożona spawanymi rurami aluminiowymi. The inner and outer surfaces of the composite pipe are coated with adhesive for bonding with the plastic layer, which is formed by processing composite technology.

Aluminum-plastic composite pipe process

Pierwszy, the longitudinal aluminum tube is made by lap welding, and the inner and outer plastic tubes are processed on the formed aluminum tube. This method is called the lap welding production process. First process the inner plastic pipe, then process the butt welded aluminum pipe, and finally wrap the outer plastic layer. This method is known as the docking production process and is widely used.

Advantages of PPR aluminum-plastic composite pipe

The main advantages of PPR aluminum-plastic composite pipe are: the strength is equivalent to that of metal pipe, easy to bend without rebound, łatwy w obróbce, good high temperature and high pressure resistance, i doskonałą odporność na korozję. The inner wall of the aluminum-plastic composite pipe is smooth, the resistance is small when passing through, and it is not easy to be blocked; it also has good flame retardancy and good heat insulation performance; due to the use of aluminum core, it can completely isolate oxygen, inhibit bacterial reproduction, and it is convenient to process and last for the longest time. The lifespan can reach more than 60 lata.

Od 1995, the average annual growth rate of aluminum-plastic pipes in Asia has exceeded 30%. Among all the pipes in the water supply system, its growth rate is the highest, surpassing many similar products, and it is more and more widely used in production and life.

Characters of PPR aluminum-plastic composite pipe

No oxygen penetration to prevent algae growth

Aluminum can block the penetration of oxygen, prevent the oxidation of equipment and materials, reduce the oxidation and corrosion of metal devices such as fins and boilers, improve the thermal efficiency of the system, and prolong the service life of the system.

Energy saving is more economical.

The thermal conductivity is 0.23-0.24 W/M.K, much smaller than that of steel pipes (43-52W/M.K) and copper pipes (383W/M.K), and can be used as thermal insulation materials.

Wysoka sztywność, wysoka wytrzymałość, odporność na wysoką temperaturę.

It has both the hygiene of plastic pipes and the rigidity of metal pipes. It has high strength and good high temperature resistance. The pipe network system has good stability and generally does not require maintenance after installation.

UV protection to prevent material aging

The aluminum layer effectively blocks UV rays and provides a UV protection barrier for the pipes. No discoloration or deterioration for outdoor installations.

The composite pipe has a small expansion coefficient and will not deform when exposed.

The expansion coefficient of the pipe is small, close to the metal pipe, and it will not deform when exposed indoors and outdoors.

The connection is firm, there is no leakage, and the installation is convenient.

The PPR steady-state pipe still adopts the same hot-melt socket connection method as the ordinary PPR pipe.

PPR aluminum-plastic composite pipe requirements for aluminum strips

  • 1. Łatwy w obróbce
  • 2. Gładka powierzchnia
  • 3. Easy to solder
  • 4. Easy to bond with plastic

Aluminum strip for ppr pipe

aluminum strip for ppr pipe is used for PPR steady-state aluminum-plastic composite pipe, which increases pipe strength, odporność na wysoką temperaturę, eliminates resonance effects, and makes the pipe more durable.
