GPM-TC320 Diversified Factory Renovation and Processing Case

In the field of industrial factory renovation, the welding quality of the piping system directly affects the safety and stability of the factory's later operation. Pipe beveling, as a core pre-treatment process before welding, determines the overall early-stage processing efficiency of the piping project based on its precision and efficiency. A client specializing in high-end factory renovation introduced the GPM-TC320 CNC pipe beveling machine from NODHA partner GIRET to perform beveling processing on stainless steel, carbon steel, and galvanized pipes involved in the project. Thanks to the machine's high adaptability and stability, it successfully completed the processing of pipes with diameters of 200-300mm and wall thicknesses of 3-10mm, with client feedback indicating that the processing results far exceeded expectations.

I. Handling Complex Working Conditions: Customized Solutions

The materials used in this factory renovation client's project included 304/316 stainless steel, Q235B carbon steel, and hot-dip galvanized steel pipes. Traditional methods of manual plasma cutting or angle grinder polishing are not only physically demanding and environmentally challenging for workers, but also present numerous difficulties:

1. Inconsistent quality: Uneven bevel angles and large fluctuations in blunt edge dimensions easily lead to defects such as incomplete fusion, slag inclusions, or weld burn-through during welding.

2. Efficiency bottleneck: Especially for large quantities of pipes of different specifications, frequent tool changes and parameter adjustments severely slow down prefabrication.

3. Poor material adaptability: Grinding galvanized pipes can damage the zinc layer, and grinding stainless steel can easily cause overheating and fading, requiring more precise cold processing techniques.

The GPM-TC320 provides a perfect solution to these problems.

II. GPM-TC320 Core Features

1. Compatibility Range: Applicable pipe diameters φ33-320mm, processing wall thicknesses covering stainless steel/alloy steel 3-21mm, carbon steel 3-30mm, capable of processing various materials including carbon steel, alloy steel, stainless steel, and low-temperature steel;

2. Power and Speed Control: Total power 4KW, cutter head speed 0-35rpm stepless frequency conversion speed regulation, flexibly matching different processing needs;

3. Clamping and Lifting: Employs multi-jaw self-centering electric clamping for precise and stable clamping; the main unit supports manual lifting, and an electric lifting module can also be added;

4. Machining Configuration: Supports simultaneous processing with 1 or 2 tools, circulating water cooling, feed rate approximately 0.1mm/r, using rotary radial mechanical feed;

5. Beveling Function: Can process V-type, I-type, and double V-type beveling (standard 37.5° V-type), meeting diverse welding beveling requirements;
