Brief Introduction 

GGW-60H Steel Pipe Bending Testing Machine is a special equipment for the technical bending test of steel pipes. The main technical parameters meet the requirements of the lasted national standard GBT232-2010“Metal Material Bending Test Method”, Article 7.3 on the test speed of (1±0.2) mm/s, and real-time digital display of the corresponding bending angle. It is suitable for metal pipe bending test specified in GB/T 244-2008 “Metal pipe bending test method”, GB/T 8162-2008 “Structural seamless steel pipe”GB/T13793-2008 "Straight seam welded steel pipe", GB/T3091-2008 "Low-pressure fluid transport bending steel pipe", YB/T 5363-2006 "Welded Stainless Steel Pipe for Decoration" and other standards method.

GGW-60H Steel Pipe Bending Testing Machine only needs to replace the corresponding bend sleeve, adjust the bending radius and replace the rollers for the steel pipe samples of different nominal diameters. The equipment has reliable accuracy, convenient use, reliable limit, and long service life. The most complete bending test machine at present.

Test Control Method

1. Manual control: the sample bending test is manually controlled, and the bending angle is manually controlled during the bending process;

2. Automatic control: The bending test is automatically controlled by the equipment, the bending angle can be set, and the angle is always displayed during the bending process, and it will automatically stop when the bending angle reaches the set angle.
