GGW-60H "Welded (Low Pressure Fluid) Steel Pipe Bending Testing Machine" is a special equipment for plane bending test of metal steel pipe.
It;s for below standard:
ISO 8491:1998 Metallic materials — Tube (in full section) — Bend test
ISO 5173:2023 Destructive tests on welds in metallic materials — Bend tests
ASTM A370-22 Standard Test Methods and Definitions for Mechanical Testing of Steel Products
The equipment is a new product developed according to GB/T244-2020 ISO8491:1998 "Metal material tube bending test method". It is suitable for metal pipe bending test methods specified in GB/T13793-2016 "Straight Seam Electric Welded Steel Pipe", GB/T3091-2015 "Welded Steel Pipe for Low Pressure Fluid Transportation", GB/T8162-2008 "Seamless Steel Pipe for Structure" and other standards. GB/T3091-2015 "Welded steel pipe for low-pressure fluid transportation" (outer diameter not more than 60.3mm (≤Φ60.3mm) welded pipe) standard in chapter 5.5 process performance in the steel pipe bending test, has been unable to complete this test efficiently and standardly, Jinan Puye technical personnel combined with relevant experts and testing units, successfully developed a welding (low pressure fluid) steel pipe special bending testing machine, can efficiently complete GB/T3091-2015 "low pressure fluid transportation with welded steel pipe" Chapter 5.5.1 Process Performance: Steel Tube Bending Test. The product is widely used in inspection units, metal pipe factories and pipeline enterprises to test the bending performance of metal pipes. GGW-60 welding (low pressure fluid) steel pipe bending testing machine is based on GW-40 steel bending testing machine based on the development of products, for different nominal caliber steel pipe specimens only need to replace the corresponding bending sleeve, adjust the bending radius and replace the roller, the equipment accuracy is reliable, easy to use, long service life, is currently the most complete welding (low pressure fluid) steel pipe bending testing machine.
