Butt walda flange ba sauki nakasawa, shãfe haske da kyau, yadu amfani, yana da m rigidity da elasticity bukatun da m butt waldi thinning mika mulki, waldi nisa daga hadin gwiwa surface ne babba, da haɗin gwiwa surface daga waldi zazzabi nakasawa, yana daukan wani more. hadaddun tsarin jiki na tari, wanda ya dace da matsa lamba ko canjin zafin jiki na bututun bututu ko zazzabi mai zafi, babban matsin lamba da ƙananan bututun zafin jiki, Kullum ana amfani da su don PN mafi girma fiye da 2.5MPa bututu da haɗin bawul; Hakanan ana amfani da shi don jigilar bututun mai tsada, mai ƙonewa, fashewar abubuwa masu fashewa.
Gabaɗaya flange ɗin welded ana yin sa ta hanyar ƙirƙira ko tsari. Lokacin da aka yi amfani da farantin karfe ko sashin karfe, dole ne a cika waɗannan buƙatu:
1.The butt waldi flange ya kamata a duba ta ultrasonic, ba tare da delamination lahani;
2.Ya kamata a yanke shi a cikin raƙuman ruwa tare da jagorancin karfe, welded a cikin zobe ta hanyar lankwasawa, da kuma saman karfe don samar da silinda na zobe. Karfe farantin ba za a machined kai tsaye cikin wuya butt waldi flange;
3.The butt weld na zobe ya kamata dauko cikakken shigar azzakari cikin farji;
4. The butt weld na zobe za a sha post-welding zafi magani, kuma za a hõre 100% ray ko ultrasonic dubawa, wanda zai hadu da II bukatun na JB4730 da ultrasonic dubawa zai hadu da I bukatun na JB4730.
Gangaren wuyan waje na flange waldawa bai kamata ya fi 70 ° ba. Siffofin fasaha na flange waldi na butt ana sarrafa su sosai yayin samarwa da walda don tabbatar da cewa zai iya taka rawarsa da ƙimarsa cikakke a samarwa da amfani.
