Frequently Asked Questions
What pipe range does QG450 cutter apply to?
It is suitable for large-diameter HDPE pipes with outer diameter from 110 mm to 450 mm.
What is the maximum cutting wall thickness?
Ultra-high max cutting thickness up to 45 mm, suitable for all kinds of super-thick-wall large pipes.
What is the maximum adaptable extrusion line speed?
Max line speed: 3 m/min, perfectly matching low-speed stable production of large thick-wall pipes.
What is the cutting motor power?
3.0 kW high-torque cutting motor for heavy-load cutting.
What is the blade specification?
Heavy-duty blade size: 115×45×3 mm, thickened and wear-resistant design.
What cutting feeding method does it adopt?
Hydraulic feeding cutting system, providing stronger and more stable cutting pressure than pneumatic type.
What brand are the main electrical components?
PLC, touch screen and all core electric parts are original SIEMENS brand.
Can it cut super-thick 45 mm pipe wall smoothly?
Yes. Professional hydraulic system and high-power motor ensure stable cutting without jamming, deformation or burrs.
Does it support online synchronous tracking cutting?
Yes, automatic synchronous following and non-stop fixed-length cutting during pipe extrusion.
What are the advantages of hydraulic cutting compared with pneumatic?
Hydraulic feeding provides greater cutting force, more stable pressure and stronger heavy-load resistance, specially designed for ultra-thick large pipes.
What is the warranty and delivery time?
12-month machine warranty (excluding wearable parts), 20–30 working days delivery, lifelong technical support.
