Hoʻohana nui ʻia nā paipu kila kila ma ka paia i nā ʻoihana ʻoihana a me nā ʻoihana, me nā mea maʻamau ʻo 304 a me 316L stainless steel. ʻO kēia mau mea kila kila ʻelua he kūpaʻa maikaʻi loa ka corrosion a me nā waiwai mechanical a no laila ua koho ʻia e like me nā mea i koho ʻia no nā paipu kila kila lahilahi. Ma lalo wau e wehewehe i ke kumu e koho ai i ke kila kila kila 304 a i ʻole 316L.

ʻO ka mea mua, pono e loaʻa i nā paipu kila kila ke kūpaʻa maikaʻi i ka corrosion no ka mea e hoʻohana pinepine ʻia lākou e lawe i nā ʻano media like ʻole, me nā wai, nā kinoea, a me nā kemika. ʻO 304 kila kila he mea kila kila maʻamau i loaʻa ka 18% chromium a me 8% nickel. Hāʻawi kēia mea hoʻohui kemika i ka 304 stainless steel maikaʻi loa i ka corrosion resistance, e kūʻē i nā media corrosive maʻamau, e like me ka wai, nā waikawa, a me nā alkalis. No laila, hoʻohana nui ʻia nā paipu stainless steel 304 i ka ʻoihana maʻamau a me nā kahua kūkulu.

I ka hoʻohālikelike ʻana, ʻoi aku ka nui o ke kūpaʻa corrosion ʻo 316L stainless steel. Loaʻa iā ia ka 2-3% molybdenum, e hāʻawi i ka pale hou aku i ka corrosion. ʻAe kēia i ka paipu kila kila 316L e hana maikaʻi i nā wahi ʻoi aku ka ʻoi aku ka maikaʻi, ʻoi aku ka nui o nā ion chloride a i ʻole nā ​​​​kino kinoea ʻē aʻe. No laila, hoʻohana nui ʻia nā paipu stainless steel 316L i nā ʻoihana kemika, moana, a me nā meaʻai, ʻoi aku ka nui o nā koi no ka pale ʻana i ka corrosion.

ʻO ka lua, pono e loaʻa i nā paipu kila kila maikaʻi nā waiwai mechanical e hoʻokō i nā pono noi like ʻole. Loaʻa i ka 304 a me 316L ke kila kila maikaʻi loa ka ikaika a me ka paʻakikī, e kūpono ana iā lākou no nā ʻōnaehana paipu ma nā wahi kiʻekiʻe a me ka wela. Eia hou, ua maʻalahi nā mea ʻelua i ka mīkini a me ka weld, e hāʻawi ana i ka maʻalahi o ka hoʻolālā.

I ka hōʻuluʻulu manaʻo, ʻo ke koho ʻana o 304 a i ʻole 316L ke kila kila ma ke ʻano he mea no nā paipu kila kila ʻeleʻele i hoʻokumu ʻia ma muli o kona kūpaʻa maikaʻi loa a me nā waiwai mechanical. Ma muli o nā pono noi kikoʻī a me nā kūlana kaiapuni, ke koho ʻana i nā mea kila kila kūpono e hiki ke hōʻoia i ka hilinaʻi a me ka lōʻihi o kāu ʻōnaehana paipu.
