Welcome to Qingdao Yongke Machinery Co., Ltd. – a trusted manufacturer of advanced plastic extrusion solutions since 2010. Our Thermoplastic Double Wall Pipe Extruding Machinery with Spiral Septic Tank Extrusion Line is engineered to provide high-efficiency production for both corrugated double-wall pipes and spiral-wound septic tanks. This integrated system combines two critical applications in one robust line, helping you diversify your product portfolio while maximizing production efficiency. Backed by our ISO9001, ISO14000, and OHSAS18001 certified facility, we deliver reliable machinery that meets global standards.
Product Overview
This extrusion line is specifically designed for producing thermoplastic dual-wall pipes (e.g., HDPE double-wall corrugated pipes) and spiral septic tanks. The double-wall pipe section uses a corrugated mold to form a smooth inner wall and a corrugated outer wall for high ring stiffness and lightweight properties. The spiral septic tank section adopts a continuous winding process to create large-diameter tanks with excellent structural integrity. Both sections share a common extruder and downstream equipment, significantly reducing floor space and investment cost.
Key Features
- Dual-Function Design: One line for double-wall pipe and spiral septic tank production – switch between modes quickly.
- High Output: Equipped with a powerful extruder (75-120mm screw) and advanced screw design for high plasticizing capacity.
- Precision Control: PLC with touch screen interface for easy monitoring of temperature, speed, and pressure.
- Energy Efficient: Frequency inverters on main motors reduce power consumption by up to 20% compared to traditional systems.
- Robust Construction: Heavy-duty frame and corrosion-resistant materials ensure long service life.
- Flexible Customization: Pipe diameter from 200mm to 1200mm; tank capacity adjustable as per client requirements.

Frequently Asked Questions
-
Q: What raw materials can this line process?
A: It is suitable for thermoplastics like HDPE, PP, and PVC. We can adjust the screw design and temperature profile based on your specific material. -
Q: Can I produce pipes of different wall thicknesses?
A: Yes. The extrusion die and vacuum calibration system allow you to adjust wall thickness within a certain range. Thicker walls may require slower line speed. -
Q: How long does it take to switch from pipe mode to septic tank mode?
A: Approximately 1.5 to 2 hours, including mold change and parameter adjustment. The control system stores recipes for quick recall. -
Q: Does the line include a downstream cutting or winding system?
A: For double-wall pipes, we provide a rotary cutter or automatic saw. For septic tanks, the winding head will cut the profile at the desired length. -
Q: What is the minimum order quantity?
A: We accept one complete line as a minimum. Customization options are available based on project requirements. -
Q: Do you provide installation and training?
A: Yes. We send engineers to your site for installation, commissioning, and operator training. Remote support is also available. -
Q: What is the lead time for this machine?
A: Typically 45-60 days after order confirmation, depending on customization level. We can expedite for urgent orders. -
Q: Is the machine CE certified?
A: The machine can be made CE compliant upon request (additional certification cost). Our standard models comply with ISO9001 quality standards.
