COD cable protection pipe making machine is used to produce spiral and corrugaed coated sub-ducts. COD pipe structure: inner with low-friction HDPE microduct, outer coated with corrugated pipes. This pipe bears high pressure, easy curving, and with light quality, so Convenient construction and is the ideal cables duct.
The COD pipe is widely used as wire and cable passing pipe underground for the bridge and streat building system.
Machine with high efficient extruders and co-extrusion technology to one-step forming the COD pipes, pipe inner or outer surface is smooth and with high qualified.

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.

Pipe production line is used to make multi-layer HDPE petrol pipe for gasoline petrol station underground pipeline system. Pipe structure is pipe in pipe, double wall type. Primary pipe is a five layer HDPE EVOH pipe, and secondary pipe is a two layer HDPE pipe.
The Petrol Pipe System is the most compact, advanced and installer friendly single and double-wall piping system. The secondary contained pipes have been developed to provide extra environmental safety. By applying an secondary pipe over the inner primary pipe, an interstitial space is created. A leak detection system can then be used to monitor the interstitial space for leaks.

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.

HDPE pipe production line machine configuration is different as per produced pipe diameter range. 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.
Big diameter HDPE pipe extrusion line can be designed as two layer co-extrusion type or 3 layer co-extrusion type.
Pipe coiler is equipped as an option, to coil pipe size from 16-32mm, or 20-63mm or much big up to 110mm.

Below Pipe making machine is used to make 3 layer PP soundproof drainage pipes. The popular soundproof pipe diameter is from 50-200mm. The pipe is made by co-extrusion technology with at least two extruders. The inner and outer layer is a thin PP layer, and middle layer is a special modified sound absorbing material. The Pipe structure is 3 layer, with thickness ratio is 10%:80%:10%.
