ASME B16.5 o se tasi o faʻamatalaga masani mo flanges ma flange faʻapipiʻi lomia e le American Society of Mechanical Engineers (ASME).O lenei tulaga e aofia ai ituaiga flanges eseese, e aofia ai fugala'au mafolafola ua.Ole tulaga ole ASME B16.5 o loʻo faʻamaoti mai ai le tele, fua faʻatatau, meafaitino, ma mea e manaʻomia mo le gaosiga mo flanges.
O le ua mafolafola fugala'au o se masini feso'ota'iga fugala'au ma le ua mafolafola mamanu uelo, fa'aoga e fa'afeso'ota'i i paipa po'o meafaigaluega e ala ile uelo.O lo'o taua i lalo se fa'amatalaga au'ili'ili i le ua mafolafola fa'ae'e uelo:
Vaega fa'avae:
1. Fuafuaga ua: O le ua ma se flange uelo mafolafola o se fausaga cylindrical protruding e fesootai i pipelines po o meafaigaluega e ala i mafolafola uelo.O le mamanu o le ua e sili atu ona malupuipuia le fesoʻotaʻiga flange, aʻo faʻaleleia le malosi atoa o le fausaga.
2. Auala fesoʻotaʻiga: O lenei flange e fesoʻotaʻi i le paipa e ala i le faʻapipiʻi mafolafola.E masani ona faia le uelo i le ua o le flange ma le tulaga o le fesoʻotaʻiga o le paipa, fausia ai se fesoʻotaʻiga mautu ma fausia se fausaga tuʻufaʻatasia i le va o le flange ma le paipa.
Fa'aoga:
1. Talosaga tau alamanuia lautele: Ua fa'apipi'i u'elo flanges e masani ona fa'aogaina i fa'alapotopotoga fa'apisinisi lautele ma e talafeagai mo feso'ota'iga paipa i lalo o tulaga maualalo ma feololo.
2. Faʻasalaga faʻapitoa: Ona o le mamanu o le flange uʻamea mafolafola, e faigofie lava ona faʻaumatia, lea e sili atu ona faigofie le tausiga ma le toe faʻaleleia o le paipa.
Meafaitino ma tulaga:
1. Filifiliga o mea: E mafai ona gaosia le fuʻa faʻapipiʻi o le ua e faʻaaoga ai mea eseese, e aofia ai le carbon steel, stainless steel, alloy steel, ma isi mea talafeagai e mafai ona filifilia e tusa ai ma siosiomaga galue ma manaʻoga.
2. Faʻamatalaga faʻapitoa: E iai faʻasalalauga faʻavaomalo eseese, e pei ole ASME, DIN, EN, ma isi, e faʻamaonia ai le mamanu, lapopoa, ma le gaosiga o manaʻoga mo le ua faʻapipiʻi faʻapipiʻi flanges.
Tulaga lelei:
1. Faʻafaigofie ona faʻapipiʻi ma faʻapipiʻi: O le mamanu o flanges uelo mafolafola e faʻapipiʻi ma faʻapipiʻi faigofie, talafeagai mo faiga e manaʻomia ai le tausiga faifaipea.
2. Tamaoaiga ma aoga: talafeagai mo tulaga e manaʻomia ai se faʻatinoga faʻapitoa ma faʻatinoga i lalo ole tulaga feololo ma maualalo.
Fa'aoga:
ASME B16.5 neck flat welding flanges o loʻo faʻaaogaina lautele i alamanuia e pei o le suauu, vailaʻau, malosiaga, fau vaa, ma vailaʻau, aemaise lava i tulaga e manaʻomia ai fesoʻotaʻiga talafeagai ma le tamaoaiga i lalo o le feololo ma le maualalo o le mamafa ma tulaga vevela.
I le aotelega, o le ASME B16.5 neck flat welding flange o se masini fesoʻotaʻiga flange e ogatasi ma tulaga faʻa-Amerika ma e talafeagai mo faʻaoga eseese tau pisinisi, tuʻuina atu filifiliga fetuutuunai e fetaui ma manaoga faʻainisinia eseese.E tatau i tagata faʻaoga ona filifili ma le faʻaeteete le ituaiga flange talafeagai, fua faʻatatau, ma mea e tusa ai ma manaoga faʻapitoa pe a faʻaaogaina.
