Valve Faitotoa Fa'amau Fa'amau
1. O loʻo faʻatinoina uma le mamanu ma le gaosiga e mulimulitaʻia le GB / T 12234, API600 ma le API602. O oloa o loʻo faʻaalia se fausaga talafeagai, faʻamaufaʻailoga faʻatuatuaina, lelei faʻatinoga ma faʻataʻitaʻiga manaia.
2. Co u'amea malo uelo fa'amau fa'amaufa'ailoga, lea o lo'o ofuina e tete'e, erosion fa'amaoniga, abrasion fa'amaoniga ma umi le ola.
3. O le pito i luga ma le fetuutuunaiga ala o le valve shaft e faʻamaʻiina ina ia mafai ona tafia ma abrasion resistant.
4. PN≥15.0MPa (vasega 900), o le lua ogatotonu e faʻaogaina se faʻamaufaʻailoga faʻamaufaʻailogaina e faʻamalosia ai le faʻamaufaʻailogaina faʻamalosia faʻatasi ai ma le maualuga o le mamafa ina ia mautinoa ai le faʻamaufaʻailoga.
5. E leai se faʻamaufaʻailoga faʻamaufaʻailoga i tua i totonu o le valve, o lea e faʻatuatuaina ai le faʻamaufaʻailoga id.
6. O mea o le faʻatumu ma le tele o le flange e mafai ona filifilia ma fetaui e tusa ai ma talosaga ma manaʻoga o le faʻaaogaina. E mafai ona fa'amalieina ituaiga uma o mana'oga faigaluega.
