ʻO nā hui kila kilahoʻohana nui ʻia e hoʻohui i nā paipu like ʻole i nā paipu.Me ka hoʻomohala wikiwiki ʻana o ke kūkulu ʻana i ka hoʻokele waiwai o nā ʻāpana kila kila, ua hoʻohana nui ʻia nā ʻāpana kila kila.Ma o ka nānā ʻana i ke kūpaʻa corrosion o ka papa passivation ma luna o ka ʻili o ke kila kila, i hui pū ʻia me ka hoʻohana ʻana i ka ʻenehana hana kiʻekiʻe a me nā lako, hoʻokō ka hana i nā pono o ka hana a me ke ola.Hoʻopiha nā mea kila kuhili kiʻekiʻe i ke āpau o ka home.
Nā lako kila kilahe ʻano paipu.Hana ʻia ʻo ia me ke kila kila, no laila ua kapa ʻia ʻo ia he mau paipu kila kila.Me: kuʻekuʻe kila kuhiliʻole, kuhiliʻole kila tee, kuhiliʻole kea keʻa, kuhiliʻole kila hoemi, kuhiliʻole kila pāpale, etc. Paipu hiki ke maheleia i ka socket type kuhiliʻole paipu paipu, threaded kuhiliʻole paipu paipu, flange type kuhiliʻole paipu paipu a welded nā paipu kila kila e like me ke ʻano pili.Hoʻohana ʻia nā kuʻekuʻe kila kila ma ka piko o ka paipu;hoʻohana ʻia nā flanges e hoʻopili i ka ʻāpana o ka pipeline a hoʻopili i ka hopena o ka pipeline.ʻO ka hui o nā paipu ʻekolu e hoʻohana i kahi paipu tee kila kila;ʻo ka hui ʻana o nā paipu ʻehā e hoʻohana i kahi paipu tee stainless steel;hoʻohana ʻia ka paipu hōʻemi kila kila e hoʻohui i ʻelua paipu o nā anawaena like ʻole.
Ua hoʻohana nuiʻia nā huila kila kila ma nāʻano likeʻole o ka hana hoʻokele waiwai aupuni, e like me ka lāʻau lapaʻau, ka meaʻai, ka pia, ka wai inu, ka biotechnology, kaʻoihana kemika, ka hoʻomaʻemaʻeʻana i ka ea, ka mokulele, kaʻoihana nukili, a me nā mea'ē aʻe. ola.
Loaʻa nā pono nui o nā mea kila kila ma ke ʻano o ka pale ʻana i ka corrosion.ʻO ka ʻoihana petrochemical, aerospace, a me nā ʻenehana nuklea ʻoi aku ka manaʻo e hoʻohana i ke kila kila.
1. No ke aha i ʻole ai ke kila kila?
ʻO ke kumu o ke kila kuhiliʻole ʻaʻole ʻāʻī ʻo ia ke ʻike ʻia ke kila kila i ke kinoea, hoʻokumu koke ʻia kahi kiʻiʻoniʻoni passivation ma luna o ka ʻili, a laila e pale ai i ka oxidation hou aʻe.Loaʻa i kēia kiʻiʻoniʻoni passivation ikaika ka ʻakika.ʻO ke kūpaʻa ʻino.Akā, ʻeleʻele nō hoʻi ia i kekahi mau kaiapuni kūikawā, e like me: ka ʻāina haʻahaʻa a me kona ʻohu kai paʻakai.
2. Ma kahi o 304, 316, 316L
ʻO 304 kila kila he mea maʻamau i ʻike ʻia ma ka ʻoihana e like me 18/8 stainless steel.Loaʻa iā ia nā hiʻohiʻona o ka hana hoʻoponopono maikaʻi a me ka paʻakikī paʻakikī, a kūpono hoʻi no ka ʻoihana a me nā mea hoʻonaninani hale.
ʻOi aku ka nui o ke kalapona o 316 ma mua o 0.08%, a ʻoi aku ke kiʻekiʻe o ka ikaika o 316 ma mua o ka mea 316L.ʻO ka maʻamau, hoʻohana ʻia nā mea 316 no nā hui ferrule.
He 0.03% ka nui o ka 316L a ua ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion.Manaʻo ʻia e hoʻohana i ka 316L no nā mea huahana pono e welded.
3. Na helehelena
Ke hoʻohālikelike ʻia me nā hui kila kalapona, hiki ke hoʻoheheʻe ʻia nā hui kila kuhili ʻole e loaʻa i kahi hiʻohiʻona alohilohi, akā pono e uhi koke ʻia ke kila kalapona me ka uhi ʻana a i ʻole ka pena ma hope o ka poli ʻana, inā ʻaʻole e nalowale ke kila kalapona i kona luster a hope ka ʻōpala. , ʻAʻole pono ke kila kila.
