Aluminum-plastic Composite Pipes Are Engineered With a Dual-Layer Structure

Aluminum-plastic composite pipes, also known as PEX-AL-PEX pipes, are recognized for their multi-layer structure that combines the benefits of plastic and metal materials. These pipes consist of an inner and outer layer of high-quality polyethylene (PEX or PE-RT) and a middle aluminum layer that provides additional strength and rigidity。The aluminum layer also acts as a barrier to oxygen, which can cause corrosion in heating systems or affect the quality of water over time.

These pipes are valued for their high-pressure resistance, kink resistance, and ability to withstand high temperatures, making them suitable for a variety of applications, including hot and cold potable water supply, heating systems, and even the transport of aggressive chemicals in industrial settings。The connection methods for these pipes can vary, but they are typically easy to install and provide a secure, leak-proof seal when properly connected.

Aluminum-plastic composite pipes are also favored for their flexibility, which allows for easier installation in tight spaces compared to rigid metal pipes. They are lightweight, contributing to easier handling and reduced installation costs. These pipes do not require additional insulation for heat preservation in hot water systems due to the low heat conductivity of the plastic layers and the aluminum layer.

Moreover, these pipes are known for their long service life, with some manufacturers stating that they can last up to 50 years under normal use。Lastly, the aluminum-plastic composite pipes are recyclable, making them an environmentally friendly choice for plumbing and piping applications.
