ʻO ka pahu keleawe he 99.9% keleawe maʻemaʻe a me nā mea hoʻohui liʻiliʻi liʻiliʻi a hoʻokō i nā kūlana ASTM i paʻi ʻia.He ʻoʻoleʻa a palupalu lākou, ʻo ia hoʻi, ua hoʻopili ʻia ka paipu i mea e palupalu ai.Hoʻopili ʻia nā paipu ʻoʻoleʻa e nā pono capillary.Hiki ke hoʻohui ʻia nā hose ma nā ʻano ʻē aʻe, e komo pū me nā mea hoʻopili a me nā lapalapa.Hana ʻia nā mea ʻelua ma ke ʻano o nā ʻano hana ʻole.Hoʻohana ʻia nā paipu keleawe i ka plumbing, HVAC, refrigeration, lako kinoea lapaʻau, nā ʻōnaehana ea a me nā ʻōnaehana cryogenic.Ma waho aʻe o nā paipu keleawe maʻamau, loaʻa pū nā paipu huila kūikawā.
ʻAʻole kūlike nā huaʻōlelo no nā paipu keleawe.Ke wili ʻia ka huahana, ʻōlelo ʻia ʻo ia i kekahi manawa he paipu keleawe no ka mea e hoʻohui i ka maʻalahi a hiki ke hoʻokuʻu maʻalahi i ka mea.Akā ʻaʻole kēia ʻokoʻa i ʻae ʻia a ʻae ʻia paha.Eia kekahi, ua kapa ʻia kekahi mau paipu keleawe paʻa paʻa pololei i kekahi manawa he paipu keleawe.Hiki ke hoʻohana ʻia kēia mau huaʻōlelo mai ka mea kūʻai aku i ka mea kūʻai aku.
Hoʻokahi like nā paipu a pau koe wale nō ka ʻokoʻa o ka mānoanoa o ka pā, me ka pahu K-ʻoi aku ka mānoanoa o nā paia a no laila ka helu kaomi kiʻekiʻe.ʻO kēia mau paipu he 1/8 ″ ka liʻiliʻi ma mua o ke anawaena o waho a loaʻa i nā nui mai 1/4 ″ a i 12″, huki ʻia (paʻakikī) a i hoʻopaʻa ʻia (māmā).Hiki ke ʻōwili ʻia ʻelua paipu pā mānoanoa a hiki i 2 iniha ke anawaena.ʻEkolu mau ʻano i hoʻopaʻa 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 hoʻoheheʻe ea a me ka hāʻawi ʻana i ke kinoea maoli a me ka LPG (K no lalo, L no loko).Kūpono nā ʻano ʻekolu a pau no ka hoʻolako ʻana i ka wai o ka hale (makemake ʻia ʻo M), ka wahie a me ka hoʻoili ʻaila (makemake ʻia ke ʻano L), nā ʻōnaehana HVAC (makemake ʻia ke ʻano L), nā noi ʻana a me nā mea hou aku.
ʻO nā pā wai, nā ʻōpala a me nā puʻu makani he mau paia lahilahi a me nā helu kaomi haʻahaʻa.Loaʻa i nā nui nominal mai 1-1 / 4 ″ a i 8 ″ a melemele.Loaʻa iā ia ma 20-kapuaʻi ka lōʻihi pololei, akā hiki ke loaʻa nā lōʻihi pōkole.
ʻO ka pahu i hoʻohana ʻia no ka hoʻololi ʻana i nā kinoea olakino he ʻano K a i ʻole ʻano L me nā koi maʻemaʻe kūikawā.Pono e hoʻoneʻe ʻia ka ʻaila i hoʻohana ʻia no ka hana ʻana i nā paipu i mea e pale aku ai iā lākou mai ka ʻā ʻana i mua o ka oxygen a e hōʻoia i ke olakino o ka mea maʻi.Hoʻopili pinepine ʻia nā paipu me nā plugs a me nā pāpale ma hope o ka hoʻomaʻemaʻe ʻana a hoʻopaʻa ʻia me ka hoʻomaʻemaʻe nitrogen i ka wā e hoʻokomo ai.
ʻO nā paipu i hoʻohana ʻia no ka ea a me ka refrigeration e hōʻike ʻia e ke anawaena o waho maoli, ʻaʻole ia i 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 kēia mau paipu no ke anawaena like.
Loaʻa nā paipu keleawe i nā ʻāpana like ʻole no nā noi kūikawā.Hiki i nā paipu keleawe Beryllium ke hoʻokokoke i ka ikaika o nā paipu kila kila, a ʻo ko lākou ikaika luhi e hoʻohana pono iā lākou i nā noi kūikawā e like me nā paipu Bourdon.ʻO ke keleawe-nickel alloy he kūpaʻa maikaʻi loa ia i ka ʻino i ka wai kai, a hoʻohana pinepine ʻia ka paipu i nā kaiaola kai kahi i hoʻonui ʻia ai 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 mau ʻia nā paipu keleawe ʻole oxygen conductive kiʻekiʻe no nā alakaʻi nalu a me nā mea like.Hiki ke hoʻohana ʻia nā paipu keleawe i uhi ʻia i ka Titanium i nā mea hoʻololi wela corrosive.
E like me ka mea i ʻōlelo ʻia ma mua, ua maʻalahi nā paipu keleawe me ka hoʻohana ʻana i nā ʻano hoʻomehana e like me ka welding a me ka brazing.ʻOiai ua lawa a maʻalahi kēia mau ʻano no nā noi e like me ka hoʻolako ʻana i ka wai o ka hale, ʻo ka hoʻomehana ka mea e hoʻopili ai ka paipu huki, kahi e hoʻohaʻahaʻa ai i kāna helu kaomi.Nui nā ʻano hana mechanical i hiki ʻole ke hoʻololi i nā waiwai o ka paipu.Hoʻopili kēia i nā mea hoʻopuʻi ahi, nā mea i hoʻopaʻa ʻia, nā mea hoʻopili a me nā mea paʻi.He mea maikaʻi loa kēia mau ʻano hana hoʻopaʻa mīkini i nā kūlana i palekana ʻole ka hoʻohana ʻana i ka lapalapa a i ʻole ka wela.ʻO kekahi pōmaikaʻi ʻo ia kekahi o kēia mau pili mechanical e maʻalahi ke wehe.
ʻO ke ala ʻē aʻe, i hoʻohana ʻia i nā kūlana kahi e puka mai ai nā lālā he nui mai ka paipu nui like, ʻo ia ka hoʻohana ʻana i kahi mea hana extrusion e hana i kahi puka i loko o ka paipu.Pono kēia ʻano e hoʻohui i ka pilina hope, akā ʻaʻole pono ka hoʻohana ʻana i nā mea pono he nui.
Hōʻuluʻulu kēia ʻatikala i nā ʻano paipu keleawe.No ka ʻike hou aku e pili ana i nā huahana ʻē aʻe, e ʻoluʻolu e ʻike i kā mākou mau alakaʻi ʻē aʻe a i ʻole e kipa i ka Thomas Sourcing Platform e ʻike i nā kumu waiwai kūpono a nānā i nā kikoʻī huahana kikoʻī.
