The difference between aluminum alloy lined plastic composite pipe system and other material pipes

1. The difference between aluminum alloy-lined plastic composite pipe and traditional metal pipe:

The aluminum alloy-lined plastic composite pipe is a lightweight rigid pipe because it is an outer layer of aluminum alloy and is lined with PPR plastic. Under the premise of ensuring the support of the pipe, the application of the aluminum alloy and the food-grade PPR plastic can minimize the pressure caused by the weight of the pipe itself, thus ensuring the rigid support of the pipe. The seismic resistance of the elastic pipe fittings can also be applied. That is to say, the aluminum alloy-lined plastic composite pipe is lighter than the conventional metal pipe, and the pipe can ensure the stability under the micro-motion condition because the traditional metal pipe snap-type connection mode is abandoned.

The metal pipe itself is too heavy, so the construction cost is high, and the traditional snap-type connection is also a rigid connection. Therefore, if a slight earthquake or the like is encountered, the safety hazard is extremely likely to occur, causing the pipe to rupture. Finally, since the traditional metal pipe is the metal itself in contact with water, there is a large amount of ions in the water, so the metal pipe is easily corroded for a long time. Not only will the quality and life of the pipeline be reduced, but also the safety level of drinking water will be a safety hazard.

2. The difference between aluminum alloy lining plastic composite pipe and traditional pure plastic pipe:

The aluminum alloy lining plastic composite pipe is a light and rigid pipe material. Therefore, the aluminum alloy lining plastic composite pipe is strictly a metal pipe, so the difference from the traditional pure plastic pipe is that the aluminum alloy lining plastic composite pipe has a rigid supporting effect, and at the same time, the aluminum The alloy-lined plastic composite pipe is much higher in pressure bearing capacity than the pure plastic pipe.

3. The difference between aluminum alloy-lined plastic composite pipe and traditional composite pipe:

The traditional composite pipe is mainly steel-lined plastic pipe. Although this pipe is lined with food-grade plastic, it can effectively increase the service life and sanitary level of the metal pipe. However, since the weight of the steel-lined plastic pipe itself is still relatively heavy, the connection method adopted is still a conventional snap-type connection, so there are still some hidden dangers in construction cost and safety.

There is also a kind of aluminum-plastic composite pipe, which is a three-layer structure outer plastic, the middle is an aluminum tube, and the inner layer is plastic. This kind of pipe has a great improvement in heat preservation compared with pure metal or pure plastic pipe, and the pressure bearing capacity is much higher than ordinary pure plastic pipe, but the aluminum-plastic composite pipe generally has a small pipe diameter and cannot be used as a building. The main pipe, branch pipe, etc., because the aluminum-plastic composite pipe itself is not high in bearing capacity, and the pressure bearing capacity is only relatively high relative to the pure plastic pipe, but far from the pressure bearing capacity of the metal pipe. However, the aluminum alloy lined plastic composite pipe, the industry standard pressure capacity up to PN2.5MPa, can fully adapt to the challenges of various positions of various buildings.
