Gruv Max: A Heavy-duty and Reliable Roll Grooving Machine for Fire Protection Projects
Preparing large-diameter, thick-wall steel pipes for grooved connections requires equipment with the right capacity and working setup. WELPING’s Gruv-Max roll grooving machine addresses these requirements with pipe diameter capacity up to 60 inches (Ø1524 mm), maximum wall thickness capacity of 20 mm, and a height-adjustable heavy-duty base.
Available in two standard size ranges, Gruv-Max provides a solution for steel pipe grooving in large fire protection systems, industrial piping, and engineering projects.
Large-Diameter Capacity up to 60 Inches
Gruv-Max is designed to handle large steel pipes, including 32-inch, 48-inch, and up to 60-inch diameters with the appropriate configuration. This extended capacity makes it an option for pipe fabrication work involving sizes beyond the scope of smaller roll grooving machines.
For contractors and fabricators preparing large pipeline components, Gruv-Max brings large-diameter grooving capability into a dedicated heavy-duty setup.
Maximum Wall Thickness Capacity of 20 mm
Pipe diameter is only part of the challenge in heavy-duty grooving. Wall thickness also determines the equipment required for the job.
Gruv-Max offers a maximum steel pipe wall thickness capacity of 20 mm, supporting thick-wall pipe preparation for demanding industrial and engineering applications. Customers can discuss their pipe diameter, wall thickness, and groove requirements with WELPING to select a suitable configuration.
Height-Adjustable Base for Different Pipe Diameters
Working with different pipe sizes requires the grooving center to match the pipe center height. Gruv-Max accommodates this through a heavy-duty support base that allows the machine’s working height to be adjusted.
This arrangement is particularly useful when processing large pipes from 32 to 60 inches, helping position the machine at an appropriate working height for the pipe being processed.
OGS or AGS Roller Options
Gruv-Max can be configured with OGS or AGS roller sets according to the required pipe connection system. These options allow the grooving configuration to be selected for the groove specifications of the project.
Specifying the connection system alongside the pipe dimensions helps establish the appropriate roller configuration from the start.
Two Standard Size Ranges
Gruv-Max is available in two standard configurations:
8–24 inches: For medium- and large-diameter steel pipe grooving, including thick-wall applications.
8–60 inches: For a broader diameter range, including extra-large steel pipes.
Customization is also available for specific pipe diameters, wall thicknesses, and project requirements, allowing customers to discuss a setup suited to their intended work.
