Chokutanga pane zvose, kuputika kwetsvinasimbi flangemakemikari ekugadzirisa kuongorora, kuongororwa kwemigumisiro inoratidza kuti kemikari yakagadzirwa nesimbi isina tsvinaflange uye weldingdata inoenderana nezvinodiwa.Iyo brinell kuomarara kweiyo flange mutsipa wepamusoro uye chisimbiso chepamusoro chinomiswa zvakateerana, uye iyo Brinell kuomarara kukosha kunosangana nezvinodiwa.Pachikonzero chekuti kemikari yedata inokodzera, pombi yepombi inosangana nezvinodiwa zvehunyanzvi, bvunzo yekuomarara inokodzera, uye chiyero chekushanda cheyedzo yekumanikidza, pombi flange inotsemuka mukati meyedzo yekumanikidza.Zvinojekeswa kuti kukanganisa kwakabatana nechimiro chemukati cheflange kana zvimwe zvisingazivikanwe zvinhu.

The leakageflangeinochekwa kubva papombi, flannel, kumisa kuongorora kukuru, yakawana kuti flange mukati mekuonekwa kwekutsemuka, 3mm kureba, 0.5mm yakafara, mutswe uye rutivi rwayo rworuboshwe rwakanga rwabudisa tsvina;Kutsemuka kwakawanda kwakawanikwa mumakomba ebhaudhi eflange.

Mazhinji asiri-metallic inclusions akawanikwa pachisimbiso chepamusoro chesimbi isina tsvina flange uye zvimwe zvinzvimbo.Mamwe asiri-metallic inclusions akagadzira makomba madiki nekuda kwekupararira pamusoro penzvimbo yekuisa chisimbiso cheflange.Makomba acho aive 2.0mm muhukuru uye 0.8mm muhukuru, uye kumucheto kwegomba kwaive nepakatsemuka kadiki kaionekwa nemeso.Iyo batch imwechete yekuwedzera austenitic Stainless simbi flanges inoiswa kune munda macro inspection.

Maflange mazhinji akawanikwa aine hurema pamatanho akasiyana, uye mamwe maflange aive akatsemuka akajeka aionekwa nemeso.Macroscopic inspection results inotaridzazve kuti butt welding flange, flange leakage uye flange pachayo ine hukama.Kuti uwedzere kuongorora chikonzero chaicho chekudonha kweflange, chidimbu chemugadziri mumwe chete uye batch imwechete yakasarudzwa zvisina tsarukano.
