What are the characteristics of PE-RT Ⅱ composite pipe?

Aluminum alloy lined plastic (PE-RTⅱ) composite pipe structure: From the structure and appearance, the aluminum alloy lined plastic (PE-RTⅱ) composite pipe has a clear priority, supplemented by aluminum alloy super pipe and plastic pipe, forming a new type of pipe with the main characteristics of "light weight and strong rigidity". Aluminum alloy plastic-lined composite pipe has the advantages of (PE-RT Ⅱ) plastic pipe, such as sanitation, corrosion resistance, low thermal conductivity and good conveying performance. At the same time, because the aluminum alloy protective layer is wrapped outside, the defects of low surface hardness, poor rigidity, large linear expansion coefficient, poor ultraviolet radiation resistance and easy aging of the plastic pipe are overcome. The composite pipe grafted with aluminum alloy lined plastic (PE-RT Ⅱ) has the advantages of superior aluminum alloy pipe performance, high hardness, good strength, impact resistance and high-grade gorgeous appearance.

The "lining" of aluminum alloy plastic-lined composite pipe is the main feature of its production process. Seamless aluminum alloy pipe and plastic pipe are organically combined by prestress technology, and the interlayer bonding strength reaches the best. ?

Seamless aluminum alloy pipe and plastic pipe are organically combined by prestress technology, and the interlayer bonding strength reaches the best. Aluminum alloy lined plastic (PE-RT Ⅱ) composite pipe is a popular aluminum alloy super pipe in recent years. This product is composed of aluminum alloy pipe and thermoplastic with a unique technological prestress, and has a double-layer structure. This kind of pipe does not deform when heated, and has strong compression resistance, horizontal and vertical, good rigidity, earthquake resistance, external impact resistance, oxygen resistance and ultraviolet resistance, which greatly improves the service life of the pipeline system. It is a rare 50-year maintenance-free new pipe.

Excellent mechanical properties: aluminum alloy plastic-lined composite pipe is a kind of light rigid pipe, which will not be lost or damaged due to accidental impact, knocking or extrusion during installation and use. Thermal conductivity: The thermal conductivity of polypropylene in the inner layer of aluminum alloy lined plastic composite pipe is 0.24w/mk, which keeps constant between 20-60℃, so the pipeline produced with it has excellent thermal insulation performance. Economy: the melt flow rate of polypropylene in the inner layer of aluminum alloy lined plastic composite pipe changes little, and the change rate of melt index of polypropylene of the same product model is generally less than 6%. Even after many times of thermal plasticization, the original excellent performance can still be maintained, which greatly improves the reuse rate of raw materials and reduces the production cost of pipelines. Long-term static pressure resistance: Long-term static pressure resistance directly affects the service life of water pipes. According to the water pressure test, the water pressure resistance of the aluminum alloy plastic-lined composite pipeline is better than that of similar pipelines, and the pipeline composed of polypropylene pipes and pipe fittings has good long-term static pressure resistance and long service life.
