O paipa u'amea su'i sa'o mo le fa'aputuina o alalaupapa o mea taua ia mo le fausiaina o fa'avae fa'aputuga i le fausiaina o alalaupapa. E masani ona latou manaʻomia le maualuga o le malosi ma le tumau e faʻafetaui i manaʻoga o le avega o le alalaupapa.
O paipa u'amea su'i sa'o mo le fa'aputuina o alalaupapa o mea taua ia mo le fausiaina o fa'avae fa'aputuga i le fausiaina o alalaupapa. E masani ona latou manaʻomia le maualuga o le malosi ma le tumau e faʻafetaui i manaʻoga o le avega o le alalaupapa. O nisi nei o faʻamatalaga autu e uiga i paipa uʻamea saʻo mo le faʻaputuina o alalaupapa:
Mea ma le malosi: O paipa uʻamea saʻo e masani ona faia i le uamea masani masani ma le malosi faʻapitoa ma le malosi e maua ai, e pei o le malosi malosi e oʻo atu i le 402MPa ma le malosi e maua ai le 235.2MPa, pe filifilia e tusa ai ma manaʻoga mamanu.
Fa'agasologa o gaosiga: e mafai ona vaevaeina paipa u'amea su'isu'i sa'o i paipa u'amea su'i sa'o maualuga-maua ma fa'asu'u arc u'u sa'o paipa u'amea su'isu'i e tusa ma le faagasologa o le gaosiga. O lo'o fa'afefeteina o lo'o fa'afefeteina paipa u'amea sa'o ua vaevaeina i UOE, RBE, JCOE paipa u'amea, ma isi e tusa ai ma a latou auala eseese.
Faiga fa'agasologa: O le fa'agasologa o le gaosiga o paipa u'amea su'isu'i sa'o e aofia ai le su'esu'eina o ipu, vili pito, mua'i punou, fai, mua'i uelo ma isi la'asaga. Faatasi ai ma i latou, o le faia o le oomiina lea o le ipu uamea i totonu o se paipa avanoa i luga o le masini fai, ma le muai uelo o le faʻaaogaina lea o le kesi faʻafefe mo le faʻaauau pea.
Puleaina lelei: O paipa uʻamea saʻo saʻo e feagai ma le tele o suʻesuʻega lelei i le taimi o le gaosiga o gaosiga, e aofia ai suʻesuʻega ultrasonic, suʻesuʻega X-ray, suʻega hydrostatic, ma isi, e faʻamautinoa ai le lelei o le uelo ma paipa.
Togafitiga faʻamaʻi: Ina ia faʻaleleia le umi o paipa uʻamea saʻo, e masani lava ona faʻafefeteina ma faʻapipiʻi togafitiga e faʻafetaui i siosiomaga faʻaoga eseese.
Avanoa o le faʻaogaina: O paipa uʻamea saʻo e masani ona faʻaaogaina i paipa feʻaveaʻi mamao e pei o kesi masani, suauʻu, alamanuia kemisi, eletise, vevela, sapalai vai ma alavai, faʻavevela afi, paipa uʻamea mamafa mo nofoaga eletise eletise, faʻauluina o le eletise, vaipuna, ma fanua fa'ainisinia e pei o fa'aputuga, alalaupapa, ma fausaga u'amea. .
Tulaga ma faʻailoga: O le gaosiga ma le faʻaogaina o paipa uʻamea saʻo e tatau ona tausisia tulaga faʻale-malo, e pei o le GB / T 30063-2013, ma isi, ma o paipa uʻamea taʻitasi o le a faʻailogaina mo le faigofie ona iloa ma siaki.
Manaoga faʻapitoa: O manaʻoga faʻapitoa o paipa uʻamea saʻo e aofia ai le lapopoa, foliga, mamafa, manaʻoga faʻapitoa, metotia o suʻega, ma isi, o ia mea uma e manaʻomia ona faʻatinoina e tusa ai ma tulaga talafeagai.
Tamaoaiga: Ona o lona faiga faigofie ma le maualuga o le gaosiga lelei, o paipa uʻamea saʻo saʻo e faʻaaogaina lautele i le fausiaina o tagata, petrochemical, alamanuia mama ma isi matagaluega. E masani ona faʻaaogaina e felauaiga vai maualalo-oomi poʻo le faia i ni vaega faʻainisinia eseese ma oloa gaosi mama.
Fetuuna'iga Siosiomaga: E mafai foi ona fa'avasegaina paipa u'amea sa'o e tusa ai ma le siosiomaga fa'aoga fa'apitoa e fa'afetaui i tulaga eleele eseese, suiga o le vevela ma isi mea tau le siosiomaga.
I se aotelega, o paipa uʻamea saʻo mo le faʻapipiʻiina o alalaupapa ua faʻaaogaina lautele i le fausiaina o alalaupapa ma isi atinaʻe ona o lo latou malosi maualuga, lelei le fausiaina ma le faʻamaoni.
