Hollow wall winding pipe machine line

The HDPE spiral heat winding machine mainly produces HDPE+PP structural wall spiral pipes with inner diameters ranging from 200mm to 4000mm by replacing different sizes of spindles, with different ring stiffness.

Hollow wall winding pipe machine line

1. Production process:

The material formula of hollow wall winding pipe is mainly composed of HDPE recycled material, polyester material, fluxing agent, desiccant, and black masterbatch.

The formula dosage is: HDPE recycled material 80-90KG, polyester material 10-20KG, auxiliary flux 3-4KG, desiccant 4-5KG and black masterbatch 4-5KG, calcium carbonate 80-90KG, calcium carbonate 800 mesh, lubricant 2-3kg.

Pipe characteristics:

HDPE hollow wall winding uses high-density polyethylene as the main raw material and adopts winding molding technology. It has the characteristics of smooth inner and outer pipe walls, low friction resistance, acid and alkali resistance, corrosion resistance, non toxicity, compression resistance, and resistance to aging. Its service life is over 50 years, easy to construct, and low engineering cost. It has become a substitute for cement pipes, cast iron pipes, and glass pipes in China.

2. The processing technology for hollow wall wrapped pipes is as follows.

1) Mix the raw materials and stir evenly

2) Heating the pipe extruder, adding the evenly mixed material into the pipe extruder, heating the molten material, and extruding the material from its mold;

3) Vacuum forming the pipes extruded by the pipe extruder, followed by water cooling;

4) The special-shaped structural profiles extruded from the extruder mold are uniformly wrapped around the roller mold at the predetermined position, and the PE molten material is extruded synchronously to weld the special-shaped structural profiles into a whole, ensuring the high quality of the structural wall pipe welds.

5) The continuous spraying system in the winding forming machine cools and solidifies the bonding points;

6) Cut according to the predetermined length.

7) The processing technology characteristics of hollow wall winding pipes are that the temperature of the molten glue extruded by the melt extruder is 10-20 degrees higher than the melting temperature of the profile.

3. Can produce pipes with different levels of ring stiffness;

4. Can provide efficient single screw extruders (using pellets) and energy-saving conical twin-screw extruders (using powder or pellets);

5. Complete model specifications, capable of producing DN200-DN3500 hollow wall pipes and DN315-1000 wellbore pipes;

6. Pipeline characteristics: The inner and outer walls are smooth, and there is a hollow layer between them.

7. Application:

Widely used in drainage and sewage pipelines in fields such as highways, municipal construction, residential areas, sports fields, squares, mines, agricultural culverts, bridges, etc.
