Product Description:

GGW-50S steel-plastic compound steel tube bending testing machine

Product introduction
This testing machine is specially used for the plane bending test on steel-plastic compound steel tube. GGW-50S “steel-plastic compound steel tube bending testing machine” developed by our company and China Academy of Building Research in accordance with GB/T244-2008 /ISO8491: 1998 Metallic Tube Test Method applies to the bending test methods for the steel-plastic tube with nominal diameter no larger than 50mm (≤DN50mm) stipulated in GB/T28897-2012 Steel Pipes of Complex Plastic. This product is widely applied to bending performance tests of metallic tube by test units, metallic tube plants and pipeline enterprises. GGW-50S steel-plastic compound steel tube bending testing machine is a product developed on the basis of GW-40 steel bar bending testing machine, and for steel-plastic compound steel tube specimens of different nominal diameters, just change corresponding bending core bushings, adjust the bending radius and change rollers. With reliable precision, ease of use and long service life, this equipment is the most perfect steel-plastic compound steel tube bending testing machine at present.
