Hana ʻia ka paipu keleawe me 99.9% keleawe maʻemaʻe a me nā mea hoʻohuihui liʻiliʻi a kūlike me nā kūlana ASTM i paʻi ʻia. He paʻakikī a palupalu lākou, ʻo ke ʻano hope ua hoʻomehana ʻia ka paipu e palupalu ai. Hoʻopili ʻia nā paipu paʻa e nā mea hoʻopili capillary. Hiki ke hoʻopili ʻia nā hose ma nā ʻano ʻē aʻe, me nā mea hoʻopili compression a me nā flares. Hana ʻia nā mea ʻelua ma ke ʻano o nā hale seamless. Hoʻohana ʻia nā paipu keleawe i ka plumbing, HVAC, refrigeration, lako kinoea lapaʻau, nā ʻōnaehana ea i hoʻopili ʻia a me nā ʻōnaehana cryogenic. Ma waho aʻe o nā paipu keleawe maʻamau, loaʻa pū nā paipu alloy kūikawā.
ʻAʻole kūlike iki ka huaʻōlelo no nā paipu keleawe. Ke wili ʻia ka huahana, i kekahi manawa ua kapa ʻia ʻo ia he paipu keleawe no ka mea e hoʻohui ia i ka maʻalahi a hiki ke pelu maʻalahi ʻia ka mea. Akā, ʻaʻole kēia ʻokoʻa he ʻokoʻa i ʻae ʻia a ʻae ʻia paha. Eia kekahi, ua kapa ʻia kekahi mau paipu keleawe paia paʻa i kekahi manawa he mau paipu keleawe. Hiki ke ʻokoʻa ka hoʻohana ʻana i kēia mau huaʻōlelo mai ka mea kūʻai aku a i ka mea kūʻai aku.
Ua like nā paipu a pau koe wale nō ka ʻokoʻa o ka mānoanoa o ka paia, me ka K-tube nona nā paia mānoanoa loa a no laila ke kiʻekiʻe loa o ke kaomi. ʻOi aku ka liʻiliʻi o kēia mau paipu ma mua o ke anawaena o waho a loaʻa i nā nui mai 1/4″ a i 12″, ʻelua i huki ʻia (paʻakikī) a me ka annealed (palupalu). Hiki ke ʻōwili ʻia ʻelua mau paipu paia mānoanoa a hiki i ke anawaena o 2 ʻīniha. ʻEkolu mau ʻano i hoʻokaʻawale ʻia e ka mea hana: ʻōmaʻomaʻo no K, uliuli no L, a ʻulaʻula no M.
He kūpono nā ʻano K a me L no nā noi kaomi e like me nā mea hoʻopili ea a me ka lawe ʻana i ke kinoea kūlohelohe a me ka LPG (K no ka honua, L no loko). He kūpono nā ʻano ʻekolu no ka hoʻolako wai home (makemake ʻia ke ʻano M), ka hoʻoili wahie a me ka ʻaila (makemake ʻia ke ʻano L), nā ʻōnaehana HVAC (makemake ʻia ke ʻano L), nā noi vacuum a me nā mea hou aku.
He lahilahi nā paia o nā paipu hoʻokahe, ʻōpala, a me nā paipu hoʻokuʻu wai a me nā helu kaomi haʻahaʻa. Loaʻa i nā nui liʻiliʻi mai 1-1/4″ a 8″ a me ka melemele. Loaʻa ia i nā lōʻihi pololei he 20 kapuaʻi, akā loaʻa pinepine nā lōʻihi pōkole.
ʻO ke ʻano K a i ʻole ke ʻano L ka paipu i hoʻohana ʻia no ka hoʻoili ʻana i nā kinoea lapaʻau me nā koi maʻemaʻe kūikawā. Pono e wehe ʻia ka ʻaila i hoʻohana ʻia no ka hana ʻana i nā paipu i mea e pale ai iā lākou mai ka ʻā ʻana i ke alo o ka oxygen a no ka hōʻoia ʻana i ke olakino o ka mea maʻi. Hoʻopaʻa pinepine ʻia nā paipu me nā plug a me nā poʻi ma hope o ka hoʻomaʻemaʻe ʻana a hoʻopaʻa ʻia me ka purge nitrogen i ka wā o ke kau ʻana.
Hōʻike ʻia nā paipu i hoʻohana ʻia no ka ea hoʻoluʻu a me ka hoʻomaʻalili e ke anawaena waho maoli, he ʻokoʻa ia ma kēia hui. Loaʻa nā nui mai 3/8″ a i 4-1/8″ no nā ʻoki pololei a me 1/8″ a i 1-5/8″ no nā wili. Ma keʻano laulā, ʻoi aku ka kiʻekiʻe o ke kaomi o kēia mau paipu no ke anawaena like.
Loaʻa nā paipu keleawe i nā ʻano hui like ʻole no nā noi kūikawā. Hiki i nā paipu keleawe Beryllium ke hoʻokokoke i ka ikaika o nā paipu hui kila, a ʻo ko lākou ikaika luhi e hoʻolilo iā lākou i mea pono loa i nā noi kūikawā e like me nā paipu Bourdon. He kūpaʻa loa ka hui keleawe-nickel i ka pala i loko o ka wai kai, a hoʻohana pinepine ʻia ka paipu i nā wahi kai kahi i loaʻa ai ka pono o ke kūʻē ʻana i ka ulu ʻana o ka barnacle. ʻO Copper-Nickel 90/10, 80/20 a me 70/30 nā inoa maʻamau no kēia mea. Hoʻohana pinepine ʻia nā paipu keleawe ʻole oxygen kiʻekiʻe no nā waveguides a me nā mea like. Hiki ke hoʻohana ʻia nā paipu keleawe i uhi ʻia me ka Titanium i nā mea hoʻololi wela corrosive.
E like me ka mea i ʻōlelo ʻia ma mua, ua maʻalahi ka hoʻopili ʻana o nā paipu keleawe me ka hoʻohana ʻana i nā ʻano hoʻomehana e like me ka wili ʻana a me ka brazing. ʻOiai ua lawa kēia mau ʻano a kūpono hoʻi no nā noi e like me ka hoʻolako wai home, ʻo ka hoʻomehana ʻana ke kumu o ka anneal o ka paipu i huki ʻia, kahi e hoʻohaʻahaʻa ai i kona helu kaomi. Aia kekahi mau ʻano mechanical i loaʻa ʻaʻole e hoʻololi i nā waiwai o ka paipu. ʻO kēia mau mea me nā flare fittings, grooved fittings, compression fittings a me push fittings. He mea pono loa kēia mau ʻano hoʻopaʻa mechanical i nā kūlana kahi i palekana ʻole ai ka hoʻohana ʻana i ka lapalapa a i ʻole ka wela. ʻO kekahi pono ʻē aʻe, ʻo ia ka maʻalahi o ka wehe ʻana i kekahi o kēia mau pilina mechanical.
ʻO kekahi ʻano hana, i hoʻohana ʻia i nā kūlana kahi e pono ai nā lālā he nui e puka mai ana mai ka paipu nui hoʻokahi, ʻo ia ka hoʻohana ʻana i kahi mea hana extrusion e hana i kahi puka pololei i loko o ka paipu. Pono kēia ʻano hana i ke kuʻi ʻana i ka pilina hope loa, akā ʻaʻole pono ka hoʻohana ʻana i nā mea hoʻopili he nui.
Hōʻuluʻulu manaʻo kēia ʻatikala i nā ʻano paipu keleawe. No ka ʻike hou aku e pili ana i nā huahana ʻē aʻe, e ʻoluʻolu e nānā i kā mākou mau alakaʻi ʻē aʻe a i ʻole e kipa i ka Thomas Sourcing Platform e ʻike i nā kumu kūpono o ka lako a i ʻole e nānā i nā kikoʻī kikoʻī o ka huahana.
