Pipe Cutting Machine Configuration
Large-Pipe Cutting from 8" to 20"
Designed for 8"–20" steel and stainless steel pipes, meeting large-pipe fabrication and installation needs.
Clean, Chip-Free Cold Cutting
Produces clean cuts without metal chips or sparks, reducing worksite cleanup.
Fully Enclosed Pump, Less Maintenance
The separate pump-and-cylinder design features a fully enclosed hydraulic pump, reducing oil changes and helping extend pump life.
Ball Transfer Pipe Stand
Ball transfer units support smooth pipe movement and rotation, making positioning and alignment easier.
Dual-Position Rollers for Different Pipe Sizes
Built-in rollers accommodate 8"–14" and 14"–20" pipes, making size changes easier while supporting smooth pipe rotation.
Built-In Wheels for Easy Relocation
The pull handle and built-in wheels make the machine easier to tilt and roll around workshops and jobsites.
Heavy-Duty Stand for Stable Pipe Support
The separate heavy-duty stand provides additional support for long pipes, helping maintain alignment with the machine while allowing smooth pipe rotation.
Heavy-Duty Blade for Large-Pipe Cutting
In our testing, the upgraded blade completed more than 15 consecutive cuts without damage or any decline in cutting efficiency. A dedicated blade for ductile cast iron pipes is also available.
