Bevelling: The Key to Strong and Reliable Welds
PRO-2 PB, PRO-5 PB, and PRO-10 PB bevellers are designed to ensure accurate pipe edge preparation, an important step for achieving durable, high-quality welds.
Minimizing errors and rework, saves both time and costs. It is particularly useful in automatic welding, incl. orbital welding, where precise pipe preparation enables a smooth process and eliminates potential issues.
PROMOTECH’s bevellers have proven themselves to be also particularly well-suited for membrane walls and boiler repairs in energy sources, renovations and maintenance.
How Does Pipe Bevelling Improve Weld Strength and Quality?
By increasing the contact surface for the weld, pipe bevelling improves even heat distribution, deep penetration and thus, results in a stronger weld. Eliminating irregularities and contaminants also minimizes the risk of future weld defects such as porosity or cracks. On the other hand, inaccurate bevels and poor fit-up can be the root cause of weld defects such as a lack of fusion/penetration, inclusions, blow through and excessive welding and labour costs.
Precision and Efficiency
Traditionally, achieving the ideal bevel on a workpiece was a labor-intensive and time-consuming task. However, now PROMOTECH’s PRO-2 PB, PRO-5 PB, and PRO-10 PB portable pipe bevelling machines, make this process quick and effortless. They are designed to mill pipes made of carbon and stainless steel, aluminium alloys, and copper-nickels and can be easily operated by one person. The speed is adjustable and depends on material, wall thickness and diameter, apart from pneumatic version.
Single-Operator Convenience
With their lightweight and ergonomic design, PROMOTECH’s pipe bevellers are perfect for single-operator use. Whether on-site or in a workshop, these machines deliver exceptional fit-up precision and high repeatability. Even in challenging positions and hard-to-reach areas.
Stable operation
New generation of PROMOTECH’s portable pipe bevellers feature spindle disc with two tool bit holders. It allows more stable, less stress-sensitive operation of tool bits, further enhancing the tool’s efficiency. New machines still have all the remaining functionality of its predecessors, including the ability to operate three tool bits (with the use of optional accessories).
Self-Centering Expandable Mandrels
Maintaining consistent positioning is critical for uniform bevels. To achieve that PROMOTECH’s bevellers are clamped from inside the pipe with the use of self-centering expandable ID mounted mandrels. In result they ensure stable, precise alignment and consistent fit-up that repetitively lead to high quality results.
Thanks to the simpler setup, transitions from one pipe or tube to another across multiple operations are quicker, improving workflow and boosting productivity.
Facing and bevelling in a single step
Simultaneous external, internal bevelling, and facing of tubes or pipes with PROMOTECH portable bevellers is simple and allows for precise pipe preparation. This is particularly critical for heavy-wall pipes in weld preparation. By maintaining accurate alignment throughout the process, the risk of errors commonly associated with switching between separate operations is minimized.
Combining facing and bevelling is very efficient in repetitive tasks. It eliminates the need to reposition pipes or change tools, reducing overall preparation time significantly. The result is a superior fit-up, and enhanced weld penetration.
J-Bevelling for enhanced welding on thick-walled pipes
Designed for larger diameters, the PRO-5 PB and PRO-10 PB offer extended functionality with a J-bevelling option, enhancing welding efficiency on thick-walled pipes.
J-bevelling is commonly used as a surface preparation method for welding thick plates and pipes. It reduces the amount of filler material needed, thereby decreasing welding time. By beveling only one side of the joint, welders can achieve improved penetration and a stronger bond between the materials.

Powered by Pneumatic or Electric Motor, or CAS-Battery
Depending on users preferences, needs and onsite conditions, PROMOTECH PRO-2 PB, PRO-5 PB and PRO-10 PB offer three drive options to suit your application.
High-torque electric motor
Electric motors require less maintanance, but need a location with reliable electrical power which not always is available.
Pneumatic motor
Pneumatic motors provide higher torque and tend to be chosen for heavy-duty applications, especially if compressed air is already present at the location.
Flexible CAS-battery system
Not only are battery-powered tools highly beneficial, but often essential in workplaces that lack access to the electrical grid. They also increase safety, especially in confined spaces.
What does a multi-brand CAS battery system means? With CAS-battery powered tools, one can conveniently interchange batteries and chargers among them, regardless of the brand, as long as they are part of the CAS alliance. New charger and all LiHD battery packs (4.0, 5.5 and 10.0 Ah) are suitable for PRO-2 PB and PRO-5 PB pipe bevellers, and all CAS battery-powered machines.
For extended operations, charge a spare battery simultaneously or keep a sufficient number of fully charged batteries on hand. This strategy guarantees uninterrupted and smooth operation.
