457mm Large Diameter Split Frame Pipe Cutting & Beveling Machine
The 457mm Large Diameter Split Frame Pipe Cutting & Beveling Machine is designed for precision cold cutting and pipe end preparation on steel pipes with outside diameters ranging from 300mm to 457mm (12–18 inches). Its robust split frame structure allows the machine to be mounted directly around existing pipelines, providing secure clamping and convenient installation for on-site machining.
Equipped with an automatic tool holder and adjustable bevel angle, this OD-mounted pipe cutter performs multiple operations, including pipe cutting, beveling, internal boring, and flange facing. It supports precise in-line cutting as well as simultaneous cutting and beveling, making it suitable for industrial pipeline fabrication, installation, and maintenance.
With a standard wall thickness capacity of up to 30mm and electric, hydraulic, or pneumatic drive options, the Model 457 provides a flexible machining solution for large-diameter steel pipe applications.
Key Features and Advantages
1. Split Frame Structure for Existing Pipeline Installation
The machine adopts a two-piece frame construction that can be opened and mounted around the outside diameter of a pipe.
This design eliminates the need to slide the machine over the pipe end, making it especially useful for fixed pipelines, large pipe sections, and locations where dismantling the pipeline is difficult.
The external clamping structure provides stable positioning during machining and supports installation on horizontal, vertical, and other accessible pipeline configurations.
2. Designed for Large-Diameter Steel Pipe Processing
With a working diameter range of 300–457mm (12–18 inches), the Model 457 is developed for machining larger steel pipelines.
Its standard configuration supports wall thicknesses up to 30mm, making it suitable for a variety of industrial pipe cutting and welding preparation tasks.
The larger working range provides an effective solution for pipeline fabrication and maintenance projects involving medium- to large-diameter pipes.
3. Multiple Pipe Machining Operations
The machine combines several pipe end preparation functions, helping reduce the need for separate machining equipment.
Available operations include:
Pipe cold cutting
Pipe end beveling
Internal boring and counterboring
Flange facing
Outside diameter machining
Pipe end preparation before welding
The actual machining functions depend on the selected cutting tools and machine configuration.
4. Adjustable Bevel Angles for Welding Preparation
Different pipeline projects may require different pipe end profiles before welding.
The Model 457 allows bevel angles to be selected according to machining requirements. Its automatic tool holder movement supports controlled machining and helps maintain consistent cutting and beveling results.
It can also perform simultaneous cutting and beveling operations, improving workflow efficiency during pipe end preparation.
5. Flexible Power Source Configurations
The machine supports different power source configurations to accommodate various industrial working environments.
Electric Drive: Suitable for applications with an appropriate electrical power supply.
Hydraulic Drive: Provides a hydraulic power option for industrial machining requirements.
Pneumatic Drive: Suitable for working environments equipped with compressed air systems.
The drive configuration can be selected according to the project requirements and final machine specifications.
6. Customization for Different Project Requirements
In addition to the Model 457, multiple machine sizes are available for different pipe outside diameters and wall thicknesses.
Customized configurations can be discussed according to pipe dimensions, material, machining functions, drive system, and actual working conditions.
Customers can provide technical drawings, samples, or project specifications for evaluation.
