Fa'ailoga o oloa a le atunu'u masani fa'afefe siaki siaki
1. O le oloa o loʻo i ai le fausaga talafeagai, faʻamaufaʻailoga faʻatuatuaina, faʻatinoga lelei ma foliga matagofie;
2. O le fa'amaufa'ailoga luga o lo'o ufiufi i Co fa'avae sima carbide, lea e lelei le ofuina o le ofuina, tete'e a'a, tete'e masi ma le ola tautua umi;
3. Fausia i totonu o pine pine fausaga faʻaitiitia le leakage fafo ma faʻalagolago i le faʻaaogaina;
4. Pe a sili atu le mamafa pe tutusa ma le 16.0mpa, o le faʻamaufaʻailogaina faʻamaufaʻailogaina e faʻaaogaina i totonu o le potu ogatotonu o le valve. O le maualuga o le maualuga o le mamafa, o le sili atu lea o le faʻamaufaʻailogaina;
5. O meafaitino ma le tele o flange ma butt welding pito e mafai ona filifilia talafeagai e tusa ai ma tulaga moni o galuega poʻo manaʻoga o tagata e faʻafetaui manaoga faʻainisinia eseese.
