| Hoʻopili: | |
| Me ka pāpale plastik e pale i nā welau ʻelua | |
| ʻeke ʻeke i ʻōwili ʻia ma waho o ka paipu | |
| ʻeke i ulana ʻia i ʻōwili ʻia ma waho o ka paipu | |
| Hoʻopili ʻia kā mākou huahana āpau, mālama ʻia, lawe ʻia e like me ka hoʻoponopono honua. | |
| Hoʻopili ʻia nā paipu me ka pepa anti-rust a me nā apo kila e pale ai i ka pōʻino.Hoʻopili ʻia nā lepili ʻike e like me ke kikoʻī maʻamau a i ʻole nā ʻōlelo a ka mea kūʻai aku.Loaʻa ka paʻi kūikawā e like me ka makemake o ka mea kūʻai aku. | |
| Eia kekahi, loaʻa ka pahu lāʻau ply no ka pale kūikawā.Hiki ke hāʻawi ʻia nā ʻano paʻi ʻē aʻe inā noi. | |
ʻIke kumu
ʻOi aku ka maikaʻi o ke kūʻē ʻana i ka corrosion intergranular ʻo ia ka corrosion ma waena o ka microstructure---ma waena o nā ʻano mea like ʻole e hana ai i ka huila.No laila, he koho waiwai nui ka 321 SS no nā huahana paipu me nā pōʻaiapuni lawelawe ma ka 800-1500º carbide precipitation range no ka mea e hoʻolōʻihi ʻia ke ola o ka huahana (e pili ana i nā māka ʻē aʻe o ke kila kila).
Nā hiʻohiʻona a me nā noi
ʻO 321 mau paipu kila kila i hana ʻia no nā noi wela kiʻekiʻe e hōʻike ana i ke kūpaʻa maikaʻi loa i ka luhi a me ka ʻūhā ʻana, kūpono ia no nā noi e like me:
E koho i nā polokalamu aerospace
ʻO nā pahu hoʻopau
Ka aila a me ke kinoea
Nā lako hana no nā kemika wela kiʻekiʻe
Nui nā noi lawelawe wela kiʻekiʻe
E like me kā mākou mau huahana i hoʻopaʻa ʻia a huki ʻia, ua hoʻopaʻa ʻia ka paipu SS 321 SS mai kahi ʻāpana ʻāpana, huki ʻia i ke ʻano coil, hoʻopili ʻia e like me ka mea e pono ai no ka hoʻokō ʻana i nā koi huhū o ka mea kūʻai aku, a hāʻawi ʻia i ka lōʻihi pololei a i ʻole ke ʻano coil.
