Product Description:

The Kela pipe production line uses high-density polyethylene (HDPE) resin as the main raw material, adopts hot winding molding process, and uses polypropylene (PP) single-walled corrugated pipe as the supporting structure to form B-row structural pipes with high external pressure resistance. It is commonly known as Kela pipe, treasury pipe or inner ribbed pipe in China. The Kra tube production line, also known as the inner rib tube production line or the hot state winding structure wall tube production line, produces Kra tube materials with smooth inner surfaces and a circular reinforced structure on the outside. It has high ring stiffness, strong impact resistance, and hot melt sealed connections, making it a truly flexible tube material.

1. The extruder platform and winding platform use precision linear guides for forward, backward, and longitudinal movement, controlled by servo motors;

2. Molding mold: diameter 200-4000mm, available for users to choose from; Ring stiffness: 2, 4, 6.3, 8, 12.5, 16 KN/m2.

3. Four extruders co extrusion technology (patented technology, patent number: ZL2013.6):

3.1. Convenient for users to choose different distribution methods based on raw material performance, color, and other requirements

3.2. Improve the strength of pipes

3.3. Reduce costs

4. European or Japanese brand ignition and flame detection devices automatically detect the working status of flames, with high production reliability and safety;

5. Advanced designed demolding device effectively protects the mold and reduces the labor intensity of personnel;

6. The entire Kra tube production line adopts an advanced PLC control system to monitor the operation during production, automatically correct the equipment operation and protection.

• Components of the production line:

1. Optimized extruder placement and channel design to reduce solution pressure and energy consumption.

2. The extruder platform and winding platform use precision linear guides, which move forward, backward, and longitudinally and are controlled by servo motors.

3. Four extruders co extrusion technology with patented technology (patent number: ZL2013.6); Different distribution methods can be selected according to the requirements of raw material performance, color, etc; Fiberglass can be added to improve the stiffness of the pipe ring, thereby reducing costs.

4. Advanced PLC control system: All units of the production line are integrated into the central control system, which can not only be linked but also controlled separately; Programmable control monitors production, automatically corrects equipment operation and adds protection.

5. Cooling cutting: adopting a single station design for cold cutting of products; Socket cutting, pneumatic cantilever control, precise size, high efficiency.

6. Demoulding device: Advanced and reliable structural design; High degree of automation, effectively protecting molds and reducing labor intensity for personnel.

• Auxiliary equipment section:

1. Trimming device: The hydraulic lift truck that travels horizontally transfers the demolded pipes from the pipe rack to the trimming rack, and trims the pipe socket to meet the appearance quality requirements of the pipes. At the same time, an electric fuse is embedded in the socket, and the pipe material is inspected and weighed.

2. PP corrugated pipe production line: dual module design, uniquely designed cooling system, production speed block, high efficiency.

3. Molding mold: diameter range of 200-4000mm; welded as a whole, easy to operate; Made of special steel, with long service life and smooth demolding.

4. Wire winding machine: Adopting a fully mechanical method, easy maintenance, strong reliability, and neat layout.
