I-tube yobhedu yenziwe nge-99.9% yobhedu ecocekileyo kunye nezinto ezincinci zokudibanisa kwaye ihambelana nemigangatho ye-ASTM epapashwe.Ziqinile kwaye zithambile, okokugqibela kuthetha ukuba umbhobho ukhutshiwe ukuze uthambe.Iityhubhu eziqinileyo zidityaniswe yi-capillary fittings.Imibhobho inokudityaniswa ngezinye iindlela, kubandakanywa izixhobo zokuxinzelela kunye namadangatye.Zombini zenziwe ngendlela yezakhiwo ezingenamthungo.Imibhobho yobhedu isetyenziselwa i-plumbing, i-HVAC, ifriji, ukunikezelwa kwegesi yonyango, iinkqubo zomoya ezixinzelelekileyo kunye neenkqubo ze-cryogenic.Ukongeza kwimibhobho yobhedu eqhelekileyo, iipayipi ezikhethekileyo ze-alloy nazo ziyafumaneka.
Isigama semibhobho yobhedu ayihambelani noko.Xa imveliso ihlanganiswe, ngamanye amaxesha ibizwa ngokuba yi-tubing yobhedu kuba yongeza ukuguquguquka kwaye ivumela ukuba izinto eziphathekayo zigobe ngokulula.Kodwa lo mahluko asingolwahlulo olwamkelwa ngokubanzi okanye olwamkelekileyo.Kwakhona, eminye imibhobho yobhedu eludongeni oluthe tye ngamanye amaxesha ibizwa ngokuba yimibhobho yobhedu.Ukusetyenziswa kwala magama kunokwahluka ukusuka kumthengisi ukuya kumthengisi.
Yonke imibhobho iyafana ngaphandle komahluko kubukhulu bodonga, kunye ne-K-tube eneendonga ezityebileyo kwaye ngoko ke iqondo eliphezulu loxinzelelo.Le mibhobho ibizwa ngokuba yi-1/8″ mincinci kunodayamitha yangaphandle kwaye ifumaneka ngokobungakanani ukusuka ku-1/4″ ukuya ku-12″, yomibini izotyiwe (nzima) kunye ne-annealed (ethambileyo).Imibhobho emibini eludongeni engqindilili nayo inokusongwa ukuya kuthi ga kwi-intshi ezi-2.Iindidi ezintathu zikhowudwa ngombala ngumenzi: eluhlaza ku-K, eluhlaza okwesibhakabhaka ku-L, kunye nobomvu kwi-M.
Iindidi ze-K kunye ne-L zifanelekile kwizicelo zoxinzelelo ezifana ne-compressors yomoya kunye nokuhanjiswa kwegesi yendalo kunye ne-LPG (K phantsi komhlaba, i-L yangaphakathi).Zonke iintlobo ezintathu zifanelekile ukunikezelwa kwamanzi asekhaya (uhlobo lwe-M olukhethwayo), ukuhanjiswa kwe-fuel kunye ne-oyile (uhlobo lwe-L olukhethiweyo), iinkqubo ze-HVAC (uhlobo lwe-L olukhethiweyo), izicelo ze-vacuum kunye nokunye.
Ukukhupha amanzi, inkunkuma kunye neetyhubhu zokukhupha umoya zineendonga ezibhityileyo kunye noxinzelelo oluphantsi.Ifumaneka ngobungakanani begama ukusuka ku-1-1/4″ ukuya ku-8″ kunye notyheli.Ifumaneka kwi-20-foot ubude obuthe tye, kodwa ubude obufutshane buhlala bufumaneka.
Iityhubhu ezisetyenziselwa ukuhambisa iigesi zonyango luhlobo lwe-K okanye uhlobo lwe-L kunye neemfuno ezikhethekileyo zokucoceka.Ioli esetyenziselwa ukwenza iityhubhu kufuneka isuswe ukuze ithintele ukuba ingatshisi phambi kweoksijini kunye nokuqinisekisa impilo yesigulane.Imibhobho idla ngokudityaniswa ngeeplagi kunye neekepusi emva kokucoca kunye nokuxutywa nge-nitrogen purge ngexesha lofakelo.
Imibhobho esetyenziselwa ukulungiswa komoya kunye nefriji iboniswa yi-diameter yangempela yangaphandle, eyona nto ikhethekileyo kweli qela.Ubungakanani buqala kwi-3/8" ukuya kwi-4-1 / 8" yokusikwa ngokuthe tye kunye ne-1/8" ukuya kwi-1-5 / 8" yeekhoyili.Ngokuqhelekileyo, le mibhobho inezinga eliphezulu loxinzelelo kwi-diameter efanayo.
Imibhobho yobhedu ifumaneka kwii-alloys ezahlukeneyo kwizicelo ezikhethekileyo.Iityhubhu zobhedu zeBeryllium zinokusondela kumandla eityhubhu zentsimbi, kwaye amandla azo okukhathala awenza abe luncedo ngakumbi kwizicelo ezikhethekileyo ezifana neetyhubhu zeBourdon.I-alloy ye-copper-nickel ixhathisa kakhulu kwi-corrosion emanzini olwandle, kwaye i-tubing isetyenziswa rhoqo kwiindawo zaselwandle apho ukuchasana nokukhula kwe-barnacle kuyinzuzo eyongezelelweyo.I-Copper-Nickel 90/10, 80/20 kunye ne-70/30 ngamagama aqhelekileyo ale nto.Iityhubhu zobhedu ezingenayo ioksijini ezisebenza kakhulu ziqhele ukusetyenziselwa amaza amaza kunye nokunye.Iityhubhu zobhedu ezigqunywe nge-Titanium zingasetyenziswa kwizitshintshi zobushushu obudlayo.
Njengoko kukhankanyiwe ngaphambili, imibhobho yobhedu idibaniswa ngokulula ngokusebenzisa iindlela zokufudumeza ezifana ne-welding kunye ne-brazing.Nangona ezi ndlela zifanelekile kwaye zilungele izicelo ezifana nokunikezelwa kwamanzi asekhaya, ukufudumeza kubangela ukuba umbhobho otsalweyo uhlambuluke, onciphisa umlinganiselo woxinzelelo.Kukho iindlela ezininzi zoomatshini ezikhoyo ezingatshintshi iipropati zombhobho.Oku kubandakanya ukufakwa kwe-flare, izixhobo ezifakwe kwi-grooved, izifakelo zoxinzelelo kunye nokufakwa kwe-push.Ezi ndlela zokubopha oomatshini ziluncedo kakhulu kwiimeko apho ukusetyenziswa komlilo okanye ukushisa kungakhuselekanga.Enye inzuzo kukuba ezinye zezi zidibanisi zoomatshini kulula ukuzisusa.
Enye indlela, esetyenziswe kwiimeko apho amasebe amaninzi kufuneka aphume kumbhobho oyintloko ofanayo, kukusebenzisa isixhobo sokukhupha ukudala i-outlet ngqo kumbhobho.Le ndlela idinga i-soldering uxhumano lokugqibela, kodwa ayifuni ukusetyenziswa kwezinto ezininzi zokufakelwa.
