As a leading manufacturer with over a decade of expertise in plastic machinery, Qingdao Yongke Machinery is proud to introduce our Compact Krah Helical Extrusion Pipe Production Line. Engineered specifically for entrepreneurs and small-to-medium enterprises, this line transforms the dream of in-house pipe manufacturing into a practical, cost-effective reality. Operating from our expansive 10,000-30,000 square meter facility, we design machinery that combines robust performance with space efficiency, making advanced pipe production technology accessible. This line is the ideal solution for businesses looking to produce high-quality drainage, sewer, or culvert pipes without the massive footprint and investment of traditional large-scale lines, perfectly aligning with the needs of regional markets and niche applications.
Our compact line is built for reliability and ease of operation, delivering consistent output that meets demanding application standards. We understand the challenges of starting or scaling a pipe production business, which is why our design prioritizes user-friendliness, energy efficiency, and low maintenance. By choosing our equipment, you gain a partner dedicated to your production success, backed by a company that exports globally to markets including North America, Southeast Asia, Europe, and Africa.
Core Product Features & Technical Advantages:
- Space-Optimized Design: The entire production line is engineered with a compact layout, significantly reducing the required factory floor space compared to conventional pipe extrusion lines. This allows for installation in smaller workshops or facilities where space is at a premium.
- Krah Helical Winding Technology: At the heart of the line is the helical winding unit. This process extrudes a profiled plastic strip and winds it helically onto a mandrel, fusing the seams to create a continuous pipe. This method produces pipes with excellent structural integrity and high ring stiffness (SN classes available), ideal for underground applications.
-
Integrated Production Process: The line is a seamless integration of key components:
- High-efficiency single-screw extruder for consistent material plastification.
- Precision profile die head for forming the specific strip profile.
- Computer-controlled helical winding and fusion station.
- PLC-based control system for synchronized operation and parameter management.
- Material Versatility: Capable of processing various thermoplastic materials such as HDPE (High-Density Polyethylene), PP (Polypropylene), and PVC. This flexibility allows you to produce pipes for different pressure ratings, chemical resistances, and application requirements.
- User-Friendly Control: Equipped with a programmable logic controller (PLC) and a human-machine interface (HMI) touchscreen. Operators can easily set parameters like pipe diameter, wall thickness, winding speed, and fusion temperature, ensuring repeatable quality and simplifying the production process.
The technical specifications below outline the capabilities of a standard configuration. Please note that many parameters can be customized to suit your specific production goals and raw material choices.
| Parameter | Specification / Description |
|---|---|
| Typical Pipe Diameter Range | 300 mm to 1200 mm (Custom sizes available) |
| Production Capacity | Varies with pipe diameter and material; designed for small-scale batch production |
| Extruder Screw Diameter | Options available (e.g., 90mm, 120mm) based on output requirements |
| Main Drive Power | Configured for energy-efficient operation |
| Control System | PLC with color HMI, supporting recipe storage and fault diagnostics |
| Pipe Wall Structure | Helically wound, structural wall profile (e.g., multi-chamber, foam-core) |
| Cooling System | Forced air or water spray cooling to ensure dimensional stability |
Investing in this compact production line offers tangible benefits for your business. It lowers the barrier to entry for pipe manufacturing, reduces dependency on external suppliers, and allows for greater control over product quality, delivery schedules, and profit margins. The ability to produce pipes on-demand for local infrastructure, agricultural, or industrial projects can create a significant competitive advantage.

Frequently Asked Questions (FAQ):
-
What is the main advantage of the Krah helical winding process over other pipe-making methods?
The Krah process creates a structurally wound pipe, resulting in high ring stiffness with efficient material use. This makes it excellent for non-pressure applications like drainage and sewerage where soil load resistance is crucial, often offering a better stiffness-to-weight ratio compared to some solid-wall pipes. -
How much factory space is typically required for this compact line?
Space requirements vary by model and configuration, but a key design goal is minimizing footprint. A typical layout might require an area approximately 20-30 meters in length and 6-8 meters in width, including operational space. We provide layout drawings during the planning phase. -
Can this line produce pipes for potable water applications?
The line can process materials suitable for potable water, like specific grades of HDPE. However, the final pipe's certification for potable water depends on the raw material used, the production process hygiene, and compliance with local drinking water standards, which must be verified by the producer. -
What level of technical expertise is needed to operate the line?
The line is designed for operational ease. Basic training is provided on machine functions, control panel operation, and routine maintenance. Operators with some mechanical or electrical experience can typically become proficient quickly. Detailed manuals and remote support are available. -
Is it possible to change the pipe diameter quickly on this line?
Diameter changes involve switching the mandrel or adjusting the winding mechanism, which requires some downtime for setup. The line is optimized for efficient batch production of specific diameters rather than frequent, rapid changes. For projects requiring multiple diameters, planning production runs is recommended. -
What kind of after-sales support and warranty do you offer?
We offer a standard warranty covering manufacturing defects. Our support includes installation guidance (often via video call), operational training, and the provision of technical manuals and spare parts lists. Technical support is accessible remotely, and critical spare parts can be shipped from our Qingdao facility. -
Can the line be customized for a specific raw material or pipe profile?
Yes, customization is a core service. We can discuss adjustments to the extruder screw/barrel, profile die design, and winding parameters to optimize performance for your chosen material (e.g., recycled content) or a unique pipe wall profile design.
