Bulging test refers to a testing method used to test the expansion ability of materials. It can determine the expansion capacity of a material under bending stress, and can also evaluate its plasticity and ductility through bulging tests. In this experiment, a specimen is clamped and subjected to bending loads at both ends, causing the material to expand. Then measure the expansion of the material under different loads in the experiment to determine its expansion capacity and plasticity. This testing method is commonly used in the testing of materials such as metals and plastics, which can help engineers and designers determine the most suitable material for their needs. Detection scope: pressure vessels, gas cylinders, swimming pools, oil tanks, gas cylinders, chillers, industrial boilers, food tanks, storage tanks, fire bottles, finished tank trucks, pressure fire extinguishers, water pumps, compressors, plunger pumps, pressure gauges, chemical reaction kettles, steel cylinders, steam boilers, pipelines, etc. Related reference standard specifications GB/T 15825.6-2008: Metal sheet formability and test methods Part 6: Cone cup test GB/T 38684-2020: Optical measurement methods for biaxial stress-strain curve bulging test of metal materials, sheets and strips GB/T 38719-2020: Hydraulic bulging test method for biaxial stress-strain curve determination of metal materials, tubes, and tubes.
