ʻOkoʻa ka ʻenehana hana a me ke kūkulu ʻana o nā paipu kila kila kila kiʻekiʻe mai nā paipu humuhumu kuʻuna. Hana pinepine ʻia nā paipu humuhumu kuʻuna e ka perforation wela ʻelua-roll cross-rolling, a hoʻohana pinepine ke kaʻina hana o nā paipu i ke kaʻina hana kaha kiʻi. Hoʻohana pinepine ʻia nā paipu kila kila kila i nā mea hana pololei a i ʻole nā mea lapaʻau. ʻAʻole wale ke kiʻekiʻe o nā kumukūʻai, akā hoʻohana pinepine ʻia lākou i nā lako a me nā mea hana koʻikoʻi. No laila, kiʻekiʻe loa nā koi no ka mea, ka pololei a me ka hoʻopau ʻana o ka ʻili o nā paipu kila kila kila pololei.
ʻO nā ʻōpala paipu o nā mea hana paʻakikī ke hana ʻia e hana pinepine ʻia e ka extrusion wela, a ʻo ke kūkulu ʻana o nā paipu e hana pinepine ʻia e ka ʻōwili anu. Hōʻike ʻia kēia mau kaʻina hana e ke kiʻekiʻe kiʻekiʻe, ka deformation plastic nui, a me nā waiwai hoʻonohonoho paipu maikaʻi, no laila ua hoʻopili ʻia.
ʻO ka maʻamau, ʻo nā paipu kila kila pololei kīwila he 301 kila kila, 304 kila kila, 316 kila kila, 316L kila kila, a me 310S kila kila. Ma keʻano laulā, ʻoi aku ka nui o nā mea NI8 i hana ʻia, ʻo ia hoʻi, nā mea ma luna o 304, a ʻaʻole i hana ʻia nā paipu kila pololei me nā mea haʻahaʻa.
He mea maʻamau ke kapa ʻia ʻo 201 a me 202 he hao kila kila, no ka mea, he magnetic a he huki ia i nā magnet. ʻAʻole magnetic nō hoʻi ʻo 301, akā he magnetic ia ma hope o ka hana anu a he huki ia i nā magnet. ʻAʻole magnetic nā 304, 316, ʻaʻohe huki i nā magnet, a ʻaʻole pili i nā magnet. ʻO ke kumu nui no ka magnetic a i ʻole ʻaʻole paha, ʻo ia ka mea kila kila i loaʻa ka chromium, nickel a me nā mea ʻē aʻe i nā ʻano like ʻole a me nā ʻano metallographic. Ke hoʻohui nei i nā ʻano i luna, he ala kūpono hoʻi ia e hoʻohana i nā magnet e hoʻoholo ai i ka maikaʻi o ke kila kila, akā ʻaʻole ʻepekema kēia ʻano hana, no ka mea, i ke kaʻina hana o ke kila kila, aia ke kaha anu, ke kaha wela, a me ka maikaʻi ma hope o ka mālama ʻana, no laila ua emi a ʻaʻole paha ka magnetism. Inā ʻaʻole maikaʻi, e ʻoi aku ka nui o ka magnetism, ʻaʻole hiki ke hōʻike i ka maʻemaʻe o ke kila kila. Hiki i nā mea hoʻohana ke hoʻoholo mai ka ʻōpala a me ke ʻano o nā paipu kila kila pololei: ka ʻoʻoleʻa, ka mānoanoa like, a inā he mau ʻōpala ma ka ʻili.
He mea nui loa nō hoʻi nā kaʻina hana ʻōwili a huki ʻana ma hope o ka hana ʻana i nā paipu. No ka laʻana, ʻaʻole kūpono ka wehe ʻana i nā lubricants a me nā oxides o ka ʻili i ka extrusion, kahi e hoʻopilikia nui ai i ka pololei a me ka maikaʻi o ka ʻili o nā paipu kila kila.
