The aluminum alloy plastic-lined (PP-R) composite pipe is a new type of composite pipe developed by Jiangsu Runshuo Pipeline Technology Co., Ltd. It has advantages such as lightweight, oxygen resistance, UV resistance, cleanliness, easy installation, strong sealing, and maintenance-free in applications for water supply pipelines. It addresses the defects of plastic pipes, such as bending due to thermal expansion and contraction, vulnerability to impact, and aging in indoor exposed installations.
Connection Method
Heat fusion socket connection, safe and reliable, saving time and effort.
Applicable Scope
Mainly suitable for hot and cold water supply in buildings, including industrial, civil hot and cold water, and heating system fields.
Product Advantages
a)Excellent mechanical properties: The aluminum alloy plastic-lined composite pipe is a lightweight rigid pipe that will not suffer loss or damage due to accidental impact, knocking, or crushing during installation and use.
b)Thermal conductivity: The thermal conductivity of the inner layer polypropylene of the aluminum alloy plastic-lined composite pipe is0.24w/mk,and remains constant between20℃and60℃. Pipes produced using this material have excellent insulation properties.
c)Economical: The melt flow rate of the inner layer polypropylene of the aluminum alloy plastic-lined composite pipe changes very little, with the melt index variation rate generally 6% for the same product model. Even after multiple heat plasticizations, it still maintains its original excellent performance, greatly improving the recyclability of the raw materials and reducing the production cost of the pipes.
d)Long-term static pressure resistance: Long-term static pressure resistance directly affects the service life of water supply pipelines. The aluminum alloy plastic-lined composite pipe has better hydraulic resistance than similar pipes in hydraulic tests. The combination of polypropylene pipes and fittings has good long-term static pressure resistance and an ultra-long service life.
e)Excellent weldability: The heat fusion joints of the pipes will not develop cracks or shrink holes due to poor heat fusion, preventing leakage and achieving maintenance-free pipeline systems, which is a typical feature of polypropylene pipes.
