O fa'aulu ulu fa'aono tetele fa'amau ASTM A 325/ASTM A 490

1. O le a le mea e faʻaoga ai faʻamaufausaga ulu hexagonal tetele?

O paʻu ma ulu hexagonal tetele o faʻamau e faʻaaogaina mo le faʻaogaina o fausaga uʻamea maualuga. O lona ulu o se foliga hexagonal tele e mafai ona tatalia le malosi maualuga ma le solo. E mafai ona latou tuʻuina atu fesoʻotaʻiga saogalemu ma sili atu ona faʻatuatuaina, o lea e faʻaaogaina lautele i alalaupapa, fale, nofoaafi, auala tetele, ma isi galuega tetele.

2. O le a le eseesega i le vaASTM A325ma le ASTM A490?

ASTM A325 ma le ASTM A490 o faʻamatalaga masani ia mo faʻamau faʻaaogaina i fausaga ulu hexagonal tetele. E eseese i latou i le malosi faaletino. ASTM A325 e masani ona fa'aoga mo fausaga feololo malosi, a'o ASTM A490 e fa'aaogaina mo fausaga tetele, maualuga le utaina.

O fa'amau A325 e tele lava ina fa'apipi'iina TYPE1 ma TYPE3. TYPE1 o lo'o fa'aogaina mo le fausaga lautele ma e mafai ona fa'a'u'u vevela pe a mana'omia. E tatau ona fa'aoga u'amea fa'afefete i le tau fa'atasi ma fa'amau TYPE3, lea e tatau ona fa'ailoga fa'apitoa i luga o le ata fa'atusa pe a fa'aogaina fa'amau TYPE3.

O le malosi o le A490 bolt e maualuga atu nai lo le A325, ae o le A490 bolt e le mafai ona Hot-dip galvanization. O fa'amau A490 ua vaevaeina i ituaiga e tolu o fa'amau ituaiga TYPE3 fa'atasi ai ma uamea tau tutusa.A325 ma A490 faʻamaue iai le lautele lautele i vae ma fa'aopoopoga o le 1/8 futu, i le va o le 1 futu ma le 1.5 futu, ma le lautele e tusa ma le 1 futu e masani ona fa'aoga.

3.O le a le ASME B18.2.6-2010?

ASME B18.2.6-2010 o se tulaga Amerika o loʻo faʻamaonia ai manaʻoga mo fuataga, meafaitino, mea faʻainisinia ma vailaʻau, gaosiga, ma le makaina o faʻamau mo fausaga ulu hexagonal tetele.

4.O le a le aoga o faʻamau mo fausaga ulu hexagonal tetele?

O le galuega autu o faʻamau e faʻaaogaina i fausaga ulu hexagonal tetele o le faʻafesoʻotaʻi lea o vaega eseese o le fausaga uʻamea, faʻapipiʻi atoa vaega. E mafai ona latou tatalia le malosi malosi ma maualuga le seismic ma le matagi. O le mea lea, o faʻamau mo fausaga ulu hexagonal tetele o se ituaiga taua o faʻamau i le inisinia faufale.
