Multilayer PEX-AL-PEX pipe
Junxing PEX-AL-PEX multilayer composite pipe is a five-layer structure that bonds cross-linked polyethylene with an internal aluminum weld layer, delivering oxygen barrier properties and shape memory for plumbing, heating and industrial fluid transport. The aluminum core prevents oxygen and gases from permeating the pipe, while the PEX layers provide flexibility and resistance to temperature changes. This composite design compensates for snap-back forces and thermal expansion, making it suitable for hot and cold water supply systems.
The pipe uses either overlapped or butt-welded aluminum cores, with ultrasonic welding for the former and argon-arc welding for the latter, both permanently bonded to inner and outer PEX layers via adhesive. The aluminum thickness is engineered to meet compressive and flexural strength demands, while the color of the PEX layer is customizable. Standard PEX-AL-PEX pipes in the industry typically feature a working temperature range of -40°C to 95°C, with pressure ratings often aligned to SDR 6 or SDR 7.3 classifications for building applications.
Common applications include construction cold and hot water supply, household heating, solar systems, swimming pools and central air conditioning. Contractors and distributors in HVAC and plumbing sectors source these pipes for their balance of metal-like strength and plastic-like flexibility. The product is widely exported from Chinese manufacturers, with buyers confirming compliance to international standards such as DIN 16892 or ASTM F1281 for pressure-rated multilayer piping.

Sourcing Multilayer PEX-AL-PEX pipe from Tianjin Junxing Pipe Group Co., Ltd. - China Import Guide
Before ordering, verify the pipe’s compliance with international standards such as DIN 16892 or ASTM F1281, as these ensure the product meets pressure and temperature requirements for your intended application. Request third-party test reports for oxygen barrier performance, pressure resistance and thermal stability, particularly if the pipe will be used in potable water or heating systems.
Confirm logistics details, including lead time, which can range from 30 to 60 days for containerized shipments from Tianjin. Incoterms such as FOB Tianjin or CIF destination port are common, with payment terms typically 30% TT in advance and 70% before shipment. Packaging should be checked for protection against UV exposure and mechanical damage during transit.
For quality checks, inspect the pipe for uniform layer bonding, consistent wall thickness and the absence of delamination. Request a sample for destructive testing, such as pressure cycling at elevated temperatures, to validate performance claims. Documentation should include material certificates, welding process details and test reports for oxygen permeability and thermal expansion.
