AbolishedMetallic materials - Tube ring hydraulic pressure test
金属材料 管环液压试验方法
Application Summary AI generated
This standard specifies a method for determining the circumferential strength and ductility of metallic tubes by applying hydraulic pressure to a ring-shaped specimen cut from the tube. It is primarily applied in the quality inspection and material evaluation of seamless and welded metal tubes used in industries such as oil and gas, pressure vessels, and structural engineering. The test is particularly relevant for assessing the performance of tubes under internal pressure conditions where the material's ability to withstand hoop stress is critical.
