金属材料 管 环扩张试验方法
Application Summary AI generated
This standard specifies a test method for evaluating the ability of metallic tubes to undergo plastic deformation under radial expansion. It is applied in the quality inspection and material selection of seamless and welded tubes used in industries such as petroleum, chemical, and boiler manufacturing. The test involves expanding a ring-shaped specimen over a conical mandrel to assess ductility and surface integrity.
