Below HDPE pipe production line is design to make multi-layer HDPE pipes, like three layer or two layer type.
Because of used material difference, like recycled material used for production cost reducing, and different color requirement etc, the multi-layer co-extrusion HDPE pipe line is offered.
Extruder numbers and capacity, model etc will be chosen as per produced pipe diameter and HDPE pipe layer structure, and thickness ratio.
For small diameter range like 20-63mm, there are several different speed models for option, the highest production speed is up to 60m/min for 20×2.0mm HDPE pipes.
And maximum HDPE pipe diameter we can make is up to 630mm.

Below pipe making machine is used to produce single layer polybutylene PB pipes, diameter range 16-32mm or 10-28mm.
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.
And that multi-layer PB oxygen barrier pipe machine can also be provided, with co-extrusion technology, like three layer EVOH oxygen barrier pipes or five layer EVOH oxygen barrier pipes.
