This oxygen barrier pipe production machine is used to produce 3 layer type PEXa/EVOH oxygen barrier pipes. The line speed is up to 20m/min.
Unlike like oxygen barrier pipes,which are made by co-extrusion technology. The PEXa oxygen barrier pipes are produced with two separate steps. Firstly the inner PEXa pipes is made by Ram extruder, the oldest extrusion technology, known as ENGEL extrusion technology. Then coated with outer oxygen barrier layer, which is done by coextrusion techlogy.

Cross-linked polyethylene (PEX) pipes used in hot water supply are required for high mechanical strength and high creep resistance at high temperature. PEXa pipes which are made by peroxide cross-linking have better performance, such as creep resistance and thermal shock resistance than the pipes made by other cross-kinking method.
Finished PEXa pipe can be coated with EVOH oxygen barrier and other protection layer, by another separate extrusion line, to get a 3 layer PEXa EVOH oxygen barrier pipe or 5 layer PEXa EVOH oxygen barrier pipes.
The three layer PEXa oxygen barrier pipe strucrues are： PEXa pipe, adhesive layer, and outer EVOH oxygen barrier layer. However the five PEXa oxygen barrier pipe structures are: inner PEXa pipe, adhesive layer, Middle EVOH oxygen barrier pipe, Adhesive layer, and outer PE protection layer.

Pexb al pexb pipe making machine is used to produce 5-layer overlap welding pex al pex composite pipes. Pipe diameter:½“，5/8”，¾“,1”,1-1/4“ or bigger up to 2-1/2”。Pipe producing process:Al strip uncoiling-inner glue and plastic layer extruding- outer glue and plastic layer extruding- pipecooling device- pipe coiling device. The produce multi-layer composite al-pexb pipes are mainly used as underfloor heating pipes in floor heating system.
The thin layer of aluminum in PEX-AL-PEX tubing acts as an oxygen barrier, preventing oxygen in the air from penetrating the system and rusting cast iron system components.

The ultrasonic overlap welding PERT-AL-PERT pipe production line is used to produce 5-layer overlap welding PERT-AL-PERT pipes. The multi-layer co-extrusion technology of KAIDE company makes the distribution of each layer of the aluminum-plastic pipe uniform and the finished pipe has good roundness. The equipment can be designed to produce different color pipes according to customers' different pipe application. The size of the pipe that can be produced: 16-63mm. Multi-layer composite co-extrusion technology is the key point that we have been the leading member in this industry since the 19th century.
