Today, HDPE/PP pipes is widely used in many aspects of our lives. When I mentioned HDPE/PP pipes, most people may just know what HDPE/PP pipes is, but they don't know how HDPE/PP pipes is made. This is probably only HDPE/PP pipes manufacturer. know. Today we will talk about the production of HDPE/PP pipes.

The first step is to melt the Krah Pipes in the main extruder: (mainly black material to provide the desired spiral resistance of the spiral) and in the co-extruder.

The second step is in the melt distributor (mostly yellow material to provide the desired bright, check-friendly inner surface). The third step is to divide the material flow of the main extruder into two types of flow: one is a laminar flow inside the spiral tube, and the other is an outer flow (corrugated layer). And adjust the ratio of these two flows. In the inner wall die, the black material (from the main extruder) will be me with the yellow material (from the co-extruder) and the result will be a solid two-color water channel spiral with a core on the other die head tube.

The fourth step is to coat the black material to produce a round shape. The strip on the inner layer mold is attached to the coated core tube of the other layer to create a tube on the rotating mandrel (V2). By closing the material flow of the second die, a solid sleeve and a spiral hole are evenly produced during the actual production of the shaped tube, which means that no additional work and machinery are required. Multiple profile structures and wall thicknesses can be created by changing the mold and production process. During operation, ensure that the rotating mandrel moves along the extrusion unit at the specified speed (V1).

Winded Profile Pipes made through these processes also has many advantages:

1. The technical advantage of producing HDPE Spiral Profile Pipe in this way is to produce sockets and jacks online: In the production process of spiral shaped pipes, the Eagle machine has specially designed for different joining methods, such as electric welding and rubber sealing joints. Production of spiral shaped tubes with sleeves and spiral grooves. Sockets and jacks do not require other machines to be built online, to meet any engineering design and help keep investment low.

2. Flexible production was achieved in this process: Eagle machine manufactures a unique spiral tube machine that allows PEHD/PP spiral tubes to be produced on a production line from DN 200 to DN4000 mm. The production change time is no more than 15 minutes, changing one diameter to another diameter, or changing one contour design to another. This machine can produce spiral tube with ring stiffness from sn1 to sn16, and can also produce pressure tube and pressureless tube.

3. Such a process can achieve high yields: with high-efficiency extruders, the output can reach 1400 kg / h.

The above is the introduction of HDPE/PP Profiled Pipe production process. Our life is inseparable from HDPE/PP pipes, so we must know more about the materials and production process of HDPE/PP pipes. For more information on HDPE/PP pipes, contact the HDPE/PP pipes manufacturer.
