Paipa Fauvela
O paipa fa'apau ose paipa e leai se mea.O le gaosiga o auala e tutusa ma le fa'au'u fa'alava, ae o lo'o iai mana'oga fa'apitoa mo le gaosiga o paipa u'amea.E tusa ai ma le maualuga o le vevela, e vaevaeina le paipa faʻafefe i totonu o faʻafuga faʻalaʻau lautele ma faʻamau faʻapipiʻi maualuga.
Gaosi auala:
① o le vevela o le faagaau fa'afugala'au masani e i lalo ifo o le 450 ℃, fa'aaogaina o paipa u'amea vevela po'o fa'aau malulu e gaosia ai paipa u'amea.
② fa'auna fa'alava fa'aoso maualuga e fa'aaogaina i tulaga o le maualuga o le vevela ma le maualuga o le paipa, o le a'afiaga o le vevela maualuga o le kasa ma le ausa vai, fa'ama'i ma le pala.Paipa u'amea ma le malosi gau maualuga, maualuga tetee i le okesene corrosion ma maua le mautu lelei faalapotopotoga.
Fa'amoemoega o paipa fa'aulaula:
① faagaau fauu masani e masani ona faaaoga e gaosia ai paipa puipui vai, faagaau i le vai vai ma super vevela paipa ausa, super vevela locomotive paipa vai, paipa asu lapopoa ma tamai paipa piliki.
② fa'auna fa'avevela fa'aulu e masani ona fa'aaogaina e gaosia ai fa'alava fa'avevela sili, fa'avevela, auala ea, le paipa ausa.
Vaega:
O paipa fa'apuna lautele ma fa'aupuga fa'alava fa'alava maualuga o lo'o fa'aalia i le fa'atinoga o le vevela maualuga.O paipa faʻalava i le lautele, poʻo le maualuga o le mamafa o le faʻafefe faʻafefe e tusa ai ma lo latou faʻaogaina e mafai ona vaevaeina i ni paipa uʻamea eseese.
