Internal Beveling Machine is a portable beveling tool developed based on years of market research and practical feedback from end-users. It features an optimized mechanical structure—including the reduction, clamping, and feed systems—balancing operational stability with the need for on-site mobility. Specifically designed for beveling large-diameter pipes in the field, it adapts to various power supply conditions to deliver high-precision cold beveling, ensuring clean, deformation-free pipe ends for subsequent welding.
The machine features a lightweight design, offering significant advantages for on-site beveling of large-diameter pipes. The clamping assembly is user-friendly, requiring only a standard wrench for adjustment and securing; the unit can be quickly fixed inside the pipe, allowing for flexible use in confined spaces, remote field sites, and emergency repair scenarios.
The machine operates with a stationary pipe and a rotating cutting tool, ensuring enhanced safety. The cold-processing method preserves the properties of the base material. The resulting pipe ends are clean, smooth, and free from deformation or burrs, fully meeting the stringent quality requirements for high-standard welding.
The power unit offers multiple configurations, including motors with various voltage specifications and engine-driven versions. Engine-driven models enable beveling operations to continue even at remote sites without external power, effectively overcoming limitations regarding on-site power supply.
Capable of processing a wide range of materials, including plastic, copper, brass, standard iron, carbon steel, aluminum, high-quality alloy steel, stainless steel, and titanium. For metal pipes, it supports various bevel profiles—such as U-type, single V-type, and J-type—and can be customized to meet specific welding process requirements.
The equipment mounts via a multi-point external clamping mechanism. Featuring a built-in quick-connect structure, it allows for rapid positioning and assembly at any point along the pipe. The simple installation and removal process significantly reduces on-site setup and commissioning time.
Utilizes a manual ratchet feed mechanism for controlled, easy operation, ensuring efficient beveling and high-quality results. The entire process is a cold-working operation, preserving the physical properties of the base pipe material.
Supports pipe diameters from 16mm to 600mm, with optional components available to accommodate specific size requirements. Beyond standard metal piping, it is suitable for cutting and beveling pipes, pressure vessels, and steam generators of various specifications.
This internal beveling machine serves sectors such as oil and gas, petrochemicals, natural gas, food processing, boiler manufacturing, pharmaceuticals, nuclear power, venue construction, and general civil engineering. It is widely used for on-site pipe installation, maintenance, and retrofitting projects.

1. Ensure the pipe is securely positioned before starting work. Use the provided wrench to tighten the internal expansion mechanism, preventing the equipment from shifting during processing.
2. Select the appropriate cutting tool angle based on the pipe material and welding process to ensure the desired bevel profile.
3. When using the engine-driven version in field environments, ensure adequate ventilation and safety precautions. Regularly inspect the reduction gear, clamping, and feed mechanisms to ensure long-term, stable operation.
Founded in 2012, Xianjin Pipeline has dedicated over a decade exclusively to the R&D of cold cutting and beveling technologies. Unlike general machinery manufacturers, our core technical team—comprising 3 senior and 5 intermediate engineers—focuses specifically on the mechanical dynamics of internal expanding clamping systems and multi-point synchronous feed mechanisms.
We practice what we preach. Our Machines are manufactured using advanced production equipment within our 1, 000㎡ facility. From heat treatment of the feed gearbox to precision grinding of the expansion mandrel, every critical component undergoes strict process control. This "Made by Experts" approach eliminates common issues like vibration marks and feed jerking, ensuring the cold-processing integrity you rely on.
Your project’s compliance is our priority. Our production line strictly adheres to ISO 9001 (Quality), ISO 14001 (Environment), and ISO 45001 (Safety) management systems. More importantly, the machine series holds CE Certification for EU market access and optional Explosion-Proof Certification for petrochemical applications. These aren't just logos—they are our promise of traceable quality and legal liability coverage for your on-site operations.
Our internal beveling machine isn't just lab-tested; it's field-proven. Since 2012, thousands of units have been deployed in extreme conditions—from the oil fields of Kazakhstan (-40°C) to the high-humidity power plants in Southeast Asia. We maintain sufficient spare parts inventory (supporting hundreds of units annually) to ensure that whether you are in Singapore or Russia, your after-sales replacement and technical guidance needs are met with minimal downtime.
Standard models don't fit all. Because we own the entire R&D and production chain, we offer OEM/ODM non-standard customization. Need a specific J-type groove for a boiler header? Require a special mandrel size for a 16mm micro-tube? Our 8-engineer team provides 1-on-1 technical consultation to modify the reduction gear ratio, feed depth, or clamping range, ensuring the machine adapts to your unique welding procedure—not the other way around.
This multifunctional internal beveling machine supports comprehensive processing of multiple pipe materials, including plastic pipes, copper, brass, iron, ordinary steel, aluminum, high-quality steel, stainless steel and titanium pipes. It is widely applicable for various metal and non-metal pipe beveling and cutting tasks for industrial pipeline projects.
The machine can process standard V-type, I-type and U-type grooves. It also supports customized processing of single V-shape and J-shape grooves according to customers’ actual welding process standards. It can match different welding design requirements of petroleum, chemical, nuclear power and boiler pipeline projects.
The equipment adopts a full cold processing method without heating the pipe during operation. It will not change the physical properties and material structure of the pipe base material. The processed pipe incision is non-deformable, burr-free and clean, which fully meets the high-precision welding quality standards of high-end industrial pipelines.
Yes. This portable beveling machine has diverse power options. It can be equipped with motors of different voltages for conventional electric construction, and can also be customized with engine driving devices. It can work stably in field environments without power supply, perfectly adapting to outdoor pipeline installation and emergency engineering maintenance.
The machine features a lightweight portable structure and unique quick-plug internal installation design. It realizes multi-point clamping on the outer pipe wall, and can be installed at any position of the pipeline quickly. Only one standard wrench is required for adjustment and fixing, which greatly saves on-site debugging time and improves construction efficiency.
The conventional processing diameter range of the equipment is 28mm to 76mm, with a maximum processing wall thickness of 15mm. The applicable processing range covers most conventional small and medium-sized industrial pipes, pressure vessels and steam generator pipelines, meeting the daily processing needs of most engineering projects.
