Mea tau metallurgical o mea
O paipa uelo fa'a'umi fa'alu'u fa'alava e gaosia mai i ipu u'amea, a'o paipa fa'afefeteina fa'asolosolo e gaosia mai i u'amea vevela.O lo'o i ai le tele o mea lelei ma e iai le fa'agasologa u'amea e mafai ona maua ai le gaosiga o le sila paipa maualuga.Mo se faʻataʻitaʻiga, o le tuʻufaʻatasiga o loʻo faʻapipiʻiina i se faiga faʻafefe vai e faʻavaveina ai le malulu, lea e mafai ai ona faʻaogaina le faʻaogaina o mea e maualalo-alloy e ausia ai faʻailoga malosi faʻapitoa ma le maualalo o le vevela, ma faʻaleleia atili ai le faʻaogaina o le sila.Ae ui i lea, o lenei faiga e tele lava ina toesea i fale gaosi ie uamea.O le anotusi u'amea (carbon e tutusa) o coils e masani ona maualalo ifo nai lo tulaga tutusa o ipu uamea, lea e faaleleia ai foi le weldability o paipa uelo silo.
E sili atu ona taua le matauina o le, talu ai e le o sa'o le ta'amilosaga o le ta'amilosaga paipa paipa uamea i le itu o le axis paipa uamea (o lona fofo pine e fa'alagolago i le tulimanu o le paipa u'amea), a'o ta'avale le u'amea sa'o. faasino tonu i le itu o le axis paipa uamea, ma o lea, o le mea uamea uelo paipa e sili atu nai lo le sa'o su'isu'i paipa ta'e tetee.
Fa'agasologa Uila
Mai le fa'agasologa o le uelo, o le paipa fa'afefeteina o le paipa ma le auala sa'o o le u'amea paipa u'amea e tutusa lava, ae o le paipa uelo sa'o o le a mautinoa lava le tele o le fa'afefe, o lea e matua fa'atupula'ia ai le avanoa o fa'aletonu o le uelo, ma le fa'aletonu o totoe o le uelo. i le weld ding e sili atu, o le uʻamea uʻamea e masani ona i ai i se tulaga faʻalavelave tolu-auala, faʻateleina le avanoa e taʻe ai.
E le gata i lea, e tusa ai ma le faagasologa o le uelo o le arc, e tatau ona i ai le uelo taitasi i le amataga o le arc ma le tapeina o le arc, ae o paipa uelo sa'o ta'itasi i le su'iga annular uelo, e le mafai ona ausia le tulaga, o lea e mafai ai ona tele atu faaletonu i le arc. tineia.
