Qingdao Yongke Machinery Co., Ltd. has been a leading manufacturer in the plastic extrusion industry since 2010, with a factory covering 10,000–30,000 square meters and a dedicated team of 51–100 professionals. Our DN3000 HDPE Pipe Production Line is a versatile, high-performance solution designed for producing large-diameter spiral corrugated pipes, smooth-wall pipes, and chemical tank profiles. This machinery integrates advanced PLC control, energy-efficient drives, and robust construction to deliver consistent output up to 500 kg/h. Whether you need pipes for municipal water supply, chemical storage tanks, or industrial drainage, our system offers the flexibility and reliability you demand.
The machine combines two core functions: HDPE/PP chemical tank extrusion and spiral corrugated pipe forming. With interchangeable tooling and adjustable parameters, you can quickly switch between producing smooth-walled pipe and corrugated profiles. The extruder features a double-layer screw design for optimal plasticizing, high torque, and low energy consumption. All electrical components are from reputable suppliers, ensuring trouble-free operation even under continuous heavy duty.

Product Features & Advantages
- Multi-function design: One machine can produce both spiral corrugated pipes and smooth-walled pipes for chemical tank sheets, reducing your investment cost.
- High-efficiency spiral forming system: The unique spiral corrugated mold ensures uniform wall thickness and excellent ring stiffness for large-diameter pipes.
- Advanced PLC control: Real-time monitoring of temperature, pressure, speed, and output. All parameters are saved for rapid product changeover.
- Energy-saving servo drive: Optional servo motors reduce power consumption by up to 30% compared to traditional AC drives.
- Robust gearbox and screw: Hardened and ground gears ensure long service life; the screw is made of nitrided steel with high wear resistance.
- Quick die change: The extruder die head can be swapped within 30 minutes, minimizing downtime.
- Vacuum sizing tank: Precision calibrating ensures consistent outer diameter and ovality, meeting international pipe standards.
- Automatic coil or straight cutting: Options include automatic caterpillar haul-off + cutter for fixed lengths, or coiler for long-length coils.
Applications

Frequently Asked Questions (FAQ)
Q1: What materials can this line process?
A: The line is designed for HDPE, PP, and PE. With minor modifications, it can also process PVC and other thermoplastics. Please contact our engineers to discuss your specific material requirements.
Q2: Can I produce both smooth and corrugated pipes on one machine?
A: Yes. The machine comes with interchangeable dies. Switching between smooth pipe and spiral corrugated pipe typically takes 20–30 minutes. The control system can store recipes for different products.
Q3: What is the maximum pipe wall thickness achievable?
A: For spiral corrugated pipes, wall thickness can range from 2 mm to 20 mm depending on diameter and material. For smooth-wall production, we can achieve up to 50 mm for tank profiles.
Q4: How long is the delivery time?
A: For standard configurations, delivery is 30–45 days after receiving deposit. Customized lines may require 50–60 days. We will provide a detailed schedule in the quotation.
Q5: Do you offer training and installation support?
A: Yes. We provide free training for 1–2 operators at our factory, and optional on-site installation supervision. Remote support is available via WhatsApp or video conference.
Q6: What certifications does your machine have?
A: Our factory is ISO9001, ISO14001, and OHSAS18001 certified. The electrical components are CE-marked (optional). We can also provide a certificate of compliance with your local standards upon request.
Q7: Can I produce chemical tanks with this line?
A: Absolutely. The extrusion machinery can produce large sheets or panels used for chemical tank fabrication. With the appropriate die, you can also produce spiral-wound tank shells. Our sales team can customize the line for specific tank sizes.
Q8: What is the warranty period?
A: We offer a 12-month warranty on the entire machine (excluding wear parts). Extended warranty options are available. Our after-sales team is ready to support you whenever needed.
