Qingdao Yongke Machinery Co., Ltd. presents a state-of-the-art HDPE Inner Rib Reinforced Spiral Winding Pipe Production Machine – a versatile solution designed for manufacturing both Krah pipes and double wall corrugated pipes. With over a decade of industry experience since 2010, our factory spanning 10,000-30,000 m² combines precision engineering with robust construction to deliver high-output, low-maintenance production lines. This machine transforms raw HDPE granules into structurally sound pipes featuring internal ribs for enhanced ring stiffness, ideal for underground drainage, sewage systems, and industrial applications. Backed by ISO9001, ISO14000, and OHSAS18001 certifications, our equipment ensures consistent quality and operational safety.
Key Features & Advantages
- Dual-function capability: Produces both Krah spiral wound pipes and double wall corrugated pipes on a single machine – reducing capital investment by up to 30%.
- Inner rib reinforced design: Integrated rib-forming section creates continuous internal stiffeners, increasing pipe strength-to-weight ratio by 40% compared to standard smooth-wall pipes.
- High precision extrusion: German-made gearbox and servo-driven extruder ensure uniform melt temperature and consistent wall thickness within ±0.2 mm tolerance.
- Energy-efficient operation: Advanced heating system with PID control reduces power consumption by 15-20% compared to conventional machines.
- Quick mold changeover: Modular tooling system allows switching between pipe diameters (200-3000 mm) in under 30 minutes, maximizing production flexibility.
- Intelligent PLC control: Touch-screen interface with recipe storage for up to 50 product specifications – minimizes operator error and setup time.

Applications & Benefits for Clients
The HDPE inner rib reinforced spiral winding pipe production line is specifically engineered for manufacturers who demand high performance in stormwater management, sewer systems, and culvert applications. The internal ribs provide superior resistance to soil loads, allowing thinner walls without compromising strength – reducing material costs by 15-25%. Combined with the flexibility to produce double wall corrugated pipes (with smooth inner wall and corrugated outer wall), this machine serves as a complete solution for municipalities, construction companies, and pipe distributors.
Key customer advantages include:
- Lower operating costs: Energy-saving motors and smart temperature control cut electricity usage by 18%.
- Minimal maintenance: All wear parts (screw, barrel, molds) are made from hardened alloy steel with lifetime exceeding 30,000 hours.
- Quick ROI: With daily output capacity of 500-2000 meters (depending on diameter), typical payback period is 12-18 months.
- Global support: Commissioning and training provided by our 10+ overseas service engineers; spare parts shipped within 48 hours.

Frequently Asked Questions
-
Q: What raw materials are compatible with this machine?
A: It is designed for HDPE (High Density Polyethylene) with MFI 0.2-1.0 g/10min. PP and ABS are also possible with minor adjustments – please consult our engineers. -
Q: Can I produce both Krah pipe and double wall corrugated pipe on the same machine?
A: Yes, the machine includes swappable forming modules. Switchover takes approximately 2-3 hours with provided tooling. -
Q: What is the minimum order quantity?
A: For standard configurations, MOQ is 1 set. Customized lines may require additional negotiation. -
Q: Do you provide installation and training?
A: Yes, we offer on-site commissioning and operator training (2-4 weeks) included in the price for first-time customers. Remote support is also available. -
Q: How long is the warranty?
A: Standard warranty is 12 months from the date of B/L, covering manufacturing defects. Extended warranty plans can be purchased. -
Q: What is the power supply requirement?
A: Default is 380V/50Hz/3-phase, but we can customize for 220V/60Hz, 440V, or other voltages as needed. -
Q: How does the inner rib reinforcement affect pipe performance?
A: The ribs increase ring stiffness (SN rating) by 30-50% compared to smooth-wall pipes of the same weight, making them ideal for deep-burial applications. -
Q: What spare parts should I keep in stock?
A: We recommend keeping a set of seals, heating bands, and a spare screw tip. A detailed spare parts list is provided with the machine manual.
