GIRET, Strategic partner, introduces a new product——GPM-CM

NODHA's partner and renowned high-end equipment manufacturer, GIRET, has launched its new product, the GPM-CM GPM-CM Pipe Circumferential Seam Milling Machine. This equipment utilizes an innovative heavy-duty forming cutter head cutting system, specifically designed for the finishing of pipe circumferential welds. It can simultaneously complete beveling and internal weld cleaning, providing an integrated, high-precision circumferential weld treatment solution for the pressure vessel and large pipeline manufacturing industries.

1. Enhancing Process Quality with Heavy-Duty Cutting Technology

In heavy manufacturing fields such as pressure vessels and energy pipelines, the welding quality of pipe circumferential welds directly affects the structural safety and service life of equipment. Traditional circumferential weld processing methods often face problems such as insufficient beveling accuracy, unstable cleaning results, and efficiency issues caused by multiple clamping operations. GIRET's GPM-CM GPM-CM Pipe Circumferential Seam Milling Machine perfectly solves these problems.

The core technological advantage of this equipment lies in its heavy-duty forming cutter head cutting solution. Utilizing a high-torque, high-rigidity cutter head system, the GPM-CM can perform precision milling of the outer bevel of pipe circumferential welds in a single setup, and efficiently and uniformly clean the welded inner wall welds. This significantly improves the consistency of the bevel shape and completely solves the problems of uneven cleaning depth and easy damage to the base material in traditional processes.

2. Adaptive Circumferential Weld Structure

Another major highlight of the GPM-CM is its unique adaptive adjustment capability. The equipment can flexibly adjust according to different pipe diameters and the actual position of the circumferential weld, ensuring that the cutter head always contacts the workpiece at the optimal angle and position. This combination of rigidity and flexibility allows the GPM-CM to meet the rigidity required for heavy-duty cutting while also possessing the flexible production capability to adapt to multiple product specifications, making it particularly suitable for the needs of large-scale pipeline mass production and customized pressure vessel production.
