GGW-25 Electric Metal Conduit Bending Testing Machine

GGW-25 Electric Metal Conduit Bending Steel Tube Welded Steel Pipes Low Pressure Bend Universal Test Machine Testing Machine

Product Introduction

Machine Overview

This machine is a specialized machine used for performing planar bending tests on metal conduits. It is widely used in the metal conduit industry, steel pipe manufacturing, pipeline enterprises, and material testing institutions to evaluate the bending performance of metal conduits. The main shaft of the machine is driven by a motor through a worm gear reducer. A bending roller is mounted on the shaft. When the machine is started, the bending roller rotates around the forming die to perform a 90° bend. After the test, the specimen is inspected for cracks.
