This oxygen barrier pipe production line are used to produce 3 or 5 layer type Polybutylene PB/EVOH oxygen barrier pipes.
Polybutylene pipe, also known as PB or Poly-B pipe, features a great flexibility and is a common type of plastic piping which is suitable for hot and cold water and central heating installations as a flexible alternative to copper in both hard and soft water areas. Polybutylene pipe is lightweight and flexible, and its soft material is especially handy for long runs, as it's very easy to bend.
Oxygen Barrier is a layer of special polymer, abbreviated EVOH, which is typically applied to the external surface or in the middle of the PB pipe. The EVOH oxygen barrier layer protects the PB tubing from the diffusion of oxygen molecules into the water of the radiant heating or hydronic heating system and significantly reduces the corrosion of common cast iron components such as circulator pumps.

The PPR-AL-PPR multi-layer composite pipe production line is used to produce 5-layer PPR aluminum-plastic pipes with a diameter of 16-63mm. The produced PPR aluminum pipes are widely applied in potable water pipeline systems which are hygienic and non-toxic. The PPR-AL-PPR pipe combines the rigidity of metal with the flexibility and pressure resistance of plastic. Pipes can afford either high pressure or high temperature -40℃-95℃. The outer PPR layer of the PPR-AL-PPR pipe production line is thicker than the inner PPRlayer, so the output of the outer layer extruder of PPR is larger than the inner layer.

This PE Irrigation Pipe Production line is used to produce PE pipe for irrigation main pipe line, pipe diameter is from 12mm to 110mm, with series of SDR5, SDR11, SDR17,SDR21, SDR26,SDR33. The stable line speed models 15m/min, 35m/min, 50m/min, The whole production line includes high efficient extruder, High Speed die head, Specialized calibrator, Vacuum Calibration tank, cooling tank, stable haul-off machine, and pipe winding machine. After some modification of this pipe production line, it also can produce three layers composite HDPE and LDPE pipe, middle layer with recycled raw materials, for saving production cost.

Weifang KAIDE plastics machinery Co.,Ltd-PE-AL-PE aluminum-plastic pipe production line is used to produce PE-AL-PE pipes for gas transportation. Pipe structure: PE inner layer-Adhestive-Thin wall thickness Aluminum layer-Adhestive-PE outer layer. Generally, customers are asking for pipe size 16-63mm, and aluminum layer thickness is 0.15-0.6mm. Using high-precision aluminum tube forming moulds and imported stable welders ensure that PE-AL-PE pipes are produced in a precise and stable welding environment. PE-AL-PE pipe machine stable producing speed 15m/min.

This oxygen barrier pipe production line is used to produce 5 layer Polyamide PA oxygen barrier automobile fuel tubes. The inner and outer layer is PA 12 material, then two bonding layer, and middle EVOH oxygen barrier layer.
This multilayer PA fuel tubes are mady by co-extrusion technology, with 5 sets of extruders. EVOH (Ethylene-Vinyl Alcohol) materials are windely used in automotive applications in multi-layer fule lines owing to their excellent barrier properties to aromatic and aliphatic hydrocarbons. These barrier materials are essential to limit environmental fuel emissions and comply with the challenging requirements of fast changing internationak regulations.

The Anti-UV Four Layers Glassfiber PPR Pipe Production Line|PPR Pipe Making Machine is used to produce 4 layers pipe, from inside layer to skin layer, it is: ppr raw materials, glassfiber raw materials, ppr raw materials, PE raw materials, the pipe diameter range: 20mm-63mm, 20mm-110mm, etc. This kind of pipe has the features of high strength, high temperature resistance, and the PE skin layer is functioned to anti Ultravoilet, to protect the inner PPR pipe, not sunburning if installed outdoor, which is mostly applied in the fields of building construction, hot water transportation, air conditioner system main pipeline,etc.
