Welina mai i ke ao o nā kuʻekuʻe kila kila, kahi e kali ai nā kihi ʻoi a me nā koho pau ʻole! Inā ʻoe e hakakā nei e koho ma waena o nā kuʻekuʻe kila kila 304 a me 316L, ʻaʻole ʻoe hoʻokahi. E ʻeli kākou i loko o kēia mau huahana ʻālohilohi a kupaianaha e kōkua iā ʻoe e hana i ke koho kūpono no kāu mau pono paipu.

304 vs. 316L: He Kuʻi ʻana o nā Titans!

 ʻO ka mea mua, e kūkākūkā kākou i nā ʻokoʻa nui ma waena o nā kuʻekuʻe kila kila 304 a me 316L. He mau koho maʻamau nā mea ʻelua, akā he mau pono a me nā hemahema ko kēlā me kēia. Ua like nā kuʻekuʻe kila kila 304 me he hoaaloha hilinaʻi lā, e kū mau ana ma nā ʻaha like ʻole.—kūpono no ka hoʻohana ʻana i kēlā me kēia lā, akā ʻaʻole kūpono no nā wahi waikawa a i ʻole ka wai kai. ʻO nā kuʻekuʻe kila kila 316L, ma ka ʻaoʻao ʻē aʻe, ʻo ia nā "superheroes" o nā kuʻekuʻe kila kila, me ka hoʻohui ʻana o ka molybdenum, kahi e hoʻonui ai i ko lākou kūpaʻa i ka pala. Inā pono ʻoe e lawelawe i nā media waikawa a alkaline paha, ʻo 316L kāu koho kūpono.

E koho i ke kihi ʻākau a me ka radius

 I kēia manawa, e kamaʻilio kākou e pili ana i nā kihi! Pono ʻoe e koho i kahi 45°, 90°, a i ʻole 180° kuʻekuʻe? Aia ia i ka nui o ke kahe a me ke kaomi i loko o kāu paipu. He 90° He kūpono ke kuʻekuʻe no nā hakahaka haiki, ʻoiai he 45° Hāʻawi ke kuʻekuʻe i kahi kahe mālie. Mai poina i ka radius o ke kūlou! ʻO nā kuʻekuʻe radius lōʻihi (1.5D) he kūpono no nā kahe kiʻekiʻe, ʻoiai hiki i nā kuʻekuʻe radius pōkole (1D) ke ʻomi i nā wahi paʻa. E hoʻomanaʻo, inā palena ka wahi, ʻo ke kuʻekuʻe radius pōkole paha kāu koho maikaʻi loa.

Nā helu kū'ē i ke kaomi: SCH10, SCH40, SCH80

 I ka wā e pili ana i ke kūpaʻa ʻana o ke kaomi, ʻo nā pae mānoanoa ʻekolu o ka paia—ʻO SCH10, SCH40, a me SCH80—ua like lākou me nā bea ʻekolu—hoʻokahi nāwaliwali loa, hoʻokahi kūpono, a hoʻokahi ikaika loa! He kūpono ʻo SCH10 no nā noi haʻahaʻa haʻahaʻa, ʻo SCH40 kahi koho āpau, a ʻo SCH80? ʻO ia no ka wā e pono ai ʻoe e kū i ke kaomi kiʻekiʻe. I nā papahana ʻenekinia, he mea nui e koho pono i ka papa kūpono e pili ana i ke kaomi o ka pipeline!

ʻAxis Nui vs. ʻAxis Liʻiliʻi: Ka Pilikia Wahial

 I ke kamaʻilio ʻana no ka hakahaka, e hoʻohālikelike kākou i nā kuʻekuʻe radius lōʻihi (1.5D) a me nā kuʻekuʻe radius pōkole (1D). He kūpono nā kuʻekuʻe radius lōʻihi no ka hōʻemi ʻana i ke kūʻē ʻana o ka wai, ʻoiai he kūpono nā kuʻekuʻe radius pōkole no ke kau ʻana i nā wahi paʻa. Inā ʻoe e hana ma nā wahi haiki, he mea pono nā kuʻekuʻe radius pōkole. Akā, mai manaʻo e kūlike kā lākou hana me nā kuʻekuʻe radius lōʻihi!

Papa ʻai vs. Papa hoʻomaʻemaʻe: Ka Pilikia Maʻemaʻe

 I kēia manawa, e nānā pono kākou i nā kuʻekuʻe kila kila maikaʻi loa no ka meaʻai a me ka mea maʻemaʻe. He kūpono nā kuʻekuʻe kila maikaʻi no nā noi meaʻai maʻamau, ʻoiai nā kuʻekuʻe kila maikaʻi loa e hana ʻia me ka poli aniani (Ra≤0.4μm) e hoʻokō i nā pono o ka hana lapaʻau kiʻekiʻe a i ʻole ka hana ʻai. He mea koʻikoʻi ke ʻano polishing—inā makemake ʻoe e mālama i ka maʻemaʻe loa, e koho i ka papa sanitary! 

Hoʻemi i nā ʻeha kuʻekuʻe lima: Nā Koa i Hoʻohanohano ʻole ʻia

 Pehea e pili ana i nā kuʻekuʻe lima e hōʻemi ana i ke kila kila? He kūpono kēia mau mea liʻiliʻi no ka hoʻohui ʻana i nā paipu o nā nui like ʻole. E hoʻomanaʻo, pono e kūlike ke anawaena a me ka mānoanoa o ka paia o nā paipu ma nā wēlau ʻelua, a i ʻole e lilo paha kāu kau ʻana i paipu i mea weliweli!

Duplex 2205/2507 vs. 316L: He Kaua o ka Ikaika

 ʻO ka mea hope loa, e hoʻohālikelike kākou i nā kuʻekuʻe kila kila duplex 2205/2507 a me nā kuʻekuʻe kila kila 316L. ʻOiai he koho maikaʻi nō hoʻi nā kuʻekuʻe kila kila 316L, hāʻawi nā kuʻekuʻe kila kila duplex i ke kūpaʻa maikaʻi loa i ka pala a me ka ikaika. Eia nō naʻe, ʻoi aku ke kumukūʻai o lākou.—hele mai ka maikaʻi ma ke kumukūʻai!

 I ka pōkole, inā ʻoe e koho i nā kuʻekuʻe kila kila 304 a i ʻole nā ​​kuʻekuʻe kila kila super 904L, hiki iā Jindalai Steel Group Co., Ltd. ke hoʻokō i kāu mau pono. Me nā kuʻekuʻe kūpono, hiki iā ʻoe ke hana koke i nā hoʻonohonoho paipu e like me ka loea! E hauʻoli i kāu hoʻonohonoho ʻana!
