Our roll groovers are designed for cold-forming precise grooves on steel pipes, stainless steel pipes, and other metal pipes used in fire protection systems, HVAC, industrial piping, and water treatment projects.
From compact manual roll grooving machines to heavy-duty electric hydraulic roll groovers, we offer a complete range of pipe grooving solutions that deliver consistent groove quality, reliable performance, and long service life on every job site.
What Is a Roll Groover and How Does It Work?
A roll groover (also called a roll grooving machine) is a mechanical tool that cold-forms a precise groove near the end of a pipe, enabling fast, reliable pipe connections using grooved couplings.
Cold Forming Process
The roll groover uses hardened steel rollers to gradually form a groove without removing material, preserving pipe wall integrity.
Precision Roll Sets
Interlocking groove roller and drive roller design ensures consistent groove depth, uniform diameter, and smooth sealing surface every time.
Flame-Free Safety
Unlike welding or threading, roll grooving is a cold process — no flame, no sparks, no fumes. Safe for use in fire-sensitive environments.

Roll Grooving Machine Applications Across Industries
Fire Protection Systems
Roll grooved pipes are the standard for fire sprinkler systems. Our roll groovers deliver precise grooves that meet NFPA requirements for reliable fire protection piping.
HVAC & Refrigeration
Grooved pipe connections are widely used in HVAC systems for fast installation and easy maintenance. Ideal for chilled water, condenser water, and hot water piping.
Industrial Piping
From mining pipelines to chemical plant piping, our heavy-duty roll groovers handle thick-wall pipes up to SCH40 and beyond for demanding industrial applications.
What Our Customers Say About Welping Roll Groovers
"We've been using Welping roll grooving machines for our fire protection projects for over 3 years. The groove consistency is excellent and the machines hold up well on job sites."
"The RG-2X heavy-duty roll groover is a beast. We groove 10" SCH40 pipes daily and it hasn't skipped a beat. Great investment for our shop."

Frequently Asked Questions About Roll Grooving Machines
What pipe materials can a roll grooving machine handle?
Welping roll groovers can handle carbon steel pipes, stainless steel pipes, galvanized pipes, and schedule 10/40 pipes. The specific capacity varies by model, ranging from 1" to 32" pipe diameters.
What is the difference between a manual and hydraulic roll groover?
Manual roll groovers are hand-operated, lightweight, and ideal for small-diameter pipes and field use. Hydraulic roll groovers use electric hydraulic systems for automated operation, offering higher efficiency and consistent groove quality for larger pipes and high-volume work.
How long does it take to groove a pipe with your roll grooving machine?
Grooving time depends on pipe size and material. For example, a 4" SCH40 steel pipe typically takes 30–60 seconds with a hydraulic roll groover. Our automatic models can be even faster for batch production in workshop settings.
Do you provide spare parts and after-sales support?
Yes! We maintain a comprehensive inventory of spare parts including groove rollers, drive rollers, hydraulic pumps, and seals. Our technical support team is available to assist with installation, operation, and maintenance questions.
Can I get a customized roll grooving machine for my specific needs?
Absolutely. With 20+ years of manufacturing experience, Welping offers OEM/ODM services. We can customize roll grooving machines to meet specific pipe sizes, wall thicknesses, voltage requirements, and accessory configurations.
