ASTM A234 Longitudinal Welded bututu
Gabatarwa:
A cikin duniyar bututun ƙarfe, kalmomi ɗaya na gama gari suna fitowa akai-akai: bututun welded mai tsayi.Wannan bututun suna taka muhimmiyar rawa a masana'antu daban-daban kuma suna aiki iri-iri.
Bututu mai walƙiya mai tsayi, wanda kuma aka sani da madaidaiciyar kabu welded bututu, bututu ne na karfe wanda aka yi da farantin karfe mai zafi ko sanyi mai birgima ko kwandon karfe.Sunan su ya fito ne daga tsarin walda, wanda ke faruwa a madaidaiciyar layi tare da tsawon bututu.Wannan hanya tana tabbatar da daidaiton ingancin walda da matsewar haɗin gwiwa, yana hana yaɗuwa da haɓaka amincin tsarin gaba ɗaya.
