HDPE Double Wall Corrugated Pipe Production Line

HDPE Dwc Pipe Machine 

The HDPE Double wall corrugated pipe production line forming machine adopts the overall horizontal structure, with small floor area and no foundation on the ground. The working platform has horizontal, vertical and horizontal adjustment mechanisms.

The governor adopts Yaskawa governor, which has reliable performance, stable speed regulation and wide speed regulation range.

The mold (air cooling + water cooling) is made of special aluminum alloy, which has the advantages of light weight, high strength, good wear resistance and small coefficient of thermal expansion.

The forming section of the forming module is long and the number of modules is small. All are completed by imported CNC machining centers, with high precision and guaranteed quality.

The double-layer on-line flare of the extruder head is designed as double screw co extrusion feed, which is extruded respectively through the double-layer die with adjustable gap.

 MPP power sheath single/double wall bellows is MPP as the main raw material, respectively, by the inner and outer extruders jointly extruded, a single molding, the inner wall is smooth, the outer wall is trapezoidal ripple-like, and there is a plastic pipe with a hollow layer between the inner and outer walls. The product has the advantages of high ring stiffness, high strength, light weight, sound insulation and shock absorption, high anti-ultraviolet stability, long service life, good bending, pressure resistance, high impact strength and so on. It can be laid in poor geological road sections, and the sealing is good and the construction is fast.

 Now we test pipe machine mould is inner diameter 175mm, OD200mm

By adjust the extruder , we can make the single wall corrugated pipe machine and double wall corrugated pipe machine

Forming machine:

Aluminium-alloy calibrator, surface is wear-resistance.

Corrugated shape is specially designed and calculated software, which has better ring-stiffness.

The sliding base of forming machine is geared and equipped with large size needle roller bearing,which improves the bearing capacity of sliding base.More stable operation,longer life.

 Production line has fixed center height, no need to adjust again when changing model

Modules can be widely used in different lines, easy to install and disassemble.

Unique internal modules cooling design, enables the cooling water to flow rapidly

Using advanced PLC and color LCD control system; stable and reliable production,high degree automation 

We cool the pipe with the water cooling and fan cooling

 MPP power sheath single/double wall corrugated pipe application field:

1, power communication: can be used as power cable, fiber optic cable sheath.

2. Municipal engineering: urban and residential underground drainage and sewage projects, highway projects, farmland water conservancy irrigation projects, etc.

Production pipe range: inner diameter Φ90-Φ250mm, with corrosion resistance, anti-aging, impact resistance, high mechanical strength, long service life, excellent electrical insulation performance and other performance characteristics.
