What’s Non-Destructive Testing (NDT)?

Non-Destructive Testing (NDT) is used in inspecting,testing,or evaluating materials,components or assemblies for discontinuities,or differences in characteristics without destroying the steel pipes,butt weld pipe fittings,forged pipe fittings or flanges.It means the products can still be used when the inspection or testing is completed.In contrast to NDT,other tests are destructive in nature and only can be used in some samples which will not be used as finished products in project.

These destructive tests are often used to calculate the physical properties of materials such as impact resistance,ductility,yield and ultimate tensile strength,fracture toughness and fatigue strength.(NDT application in steel pipe fittings manufacturing)

Today modern nondestructive tests are used in manufacturing,fabrication and in-service inspections to ensure product integrity and reliability,to control manufacturing processes,lower production costs and to maintain a uniform quality level.During construction,NDT is used to ensure the quality of materials and joining processes during the fabrication and erection phases,and in-service NDT inspections are used to ensure that the products in use continue to have the integrity necessary to ensure their usefulness and the safety of the public.
