Qingdao Yongke Machinery Co., Ltd., a dedicated manufacturer established in 2010, proudly presents the Krah Marine Pipe Machine with Touch Screen PLC and Digital Display for Pipe Forming. This advanced equipment is engineered for the continuous production of large-diameter spiral-wound pipes, specifically designed for marine and industrial applications. Combining precision control with robust construction, our machine delivers high-efficiency pipe forming while ensuring consistent wall thickness and smooth inner/outer surfaces. With over 10 years of manufacturing experience and a factory spanning 10,000–30,000 square meters, we are committed to providing reliable solutions that meet international standards.
The heart of this machine lies in its touch screen PLC system coupled with a digital display, allowing operators to monitor and adjust critical parameters in real time. From melt temperature to winding speed, every process is optimized for minimal waste and maximum output. Whether you need marine discharge pipes, stormwater drainage pipes, or chemical-resistant conduits, this versatile machine adapts to your specific requirements. Our team of 51–100 skilled employees ensures every unit is assembled with precision and tested rigorously before shipment.
Below are the key technical features and specifications that set our Krah Marine Pipe Machine apart from conventional solutions.
▶ Core Features & Benefits
- Intuitive Touch Screen PLC Control: User-friendly interface with multilingual support. Programmable logic controller enables automatic synchronization of extruder, winding mandrel, and cooling system.
- Digital Display for Real-Time Monitoring: Shows key parameters such as pipe diameter, wall thickness, production speed, and temperature zones. Instant alerts for deviations.
- High-Efficiency Extrusion System: Equipped with a specially designed single-screw extruder that ensures uniform melting and consistent material output. Suitable for HDPE, PP, and PVC (material changeover kits available).
- Precision Winding & Calibration: The rotating mandrel and forming unit produce pipes with smooth inner bores. Calibration tank maintains accurate diameter and roundness.
- Robust Construction: Heavy-duty steel frame with anti-corrosion coating for long-term marine environment use. All electrical components are IP54 rated.
- Energy-Saving Design: Optimized heating system reduces power consumption by up to 15% compared to conventional models, lowering operating costs.
- Easy Maintenance: Modular design allows quick access to extruder screw, die head, and cooling sections. Spare parts are readily available from our Qingdao warehouse.

❓ Frequently Asked Questions
-
Q: What materials can this Krah pipe machine process?
A: It can process HDPE, PP, and PVC. We recommend using virgin or recycled pellets with proper melt flow index. For special materials (e.g., PE-RT), please consult our engineers. -
Q: What is the minimum order quantity?
A: The MOQ is 1 set. However, for large-diameter mandrels (over 2000 mm), a lead time of 45–60 days may be required due to customization. -
Q: Does the machine come with a touch screen in my language?
A: Yes, the PLC interface supports English, Chinese, Spanish, French, Arabic, and more. Additional languages can be programmed upon request. -
Q: How much floor space is needed?
A> The basic machine occupies approximately 15m × 5m. Additional space is needed for material storage, granulator, and cooling tower. We provide a layout drawing with the quotation. -
Q: Can I produce pipes with spiral reinforcement (ribbed)?
A: Yes, the machine can produce both smooth and spiral-reinforced pipes by using a profile extrusion die. Additional auxiliary equipment may be needed. -
Q: What is the power supply requirement?
A: Standard is 380V/50Hz three-phase. 440V/60Hz or other custom voltages can be arranged at no extra cost for transformer equipped models. -
Q: Do you provide after-sales technical support?
A: Absolutely. We offer free remote troubleshooting via video call, and spare parts can be shipped within 72 hours. On-site service is available at cost. -
