A matsayin muhimmin bututun sufuri, ana amfani da bututun ƙarfe marasa shinge sosai a fannin man fetur, iskar gas, masana'antar sinadarai, wutar lantarki da sauran masana'antu. A lokacin amfani da su, dole ne a gwada su sosai don tabbatar da inganci da amincin bututun. Wannan labarin zai gabatar da gwajin bututun ƙarfe mara shinge daga fannoni biyu: abubuwan gwaji da hanyoyin.

Abubuwan gwaji sun haɗa da siffa, girma, ingancin saman, abubuwan da ke cikin sinadarai, tensile, tasiri, lanƙwasawa, walƙiya, lanƙwasawa, matsin lamba na hydraulic, Layer galvanized, da sauransu.
