Ishubhu yethusi lakhiwe ngethusi elimsulwa elingu-99.9% kanye nezinto ezincane zokuhlanganisa futhi lihambisana nezindinganiso ze-ASTM ezishicilelwe. Ziqinile futhi zithambile, lokhu okugcina kusho ukuthi ipayipi lifakwe ukuze lithambe. Amashubhu aqinile axhunywe ngezinsimbi zokufaka ama-capillary. Amapayipi angaxhunywa ngezinye izindlela, okuhlanganisa nokufakwa kokucindezela kanye nama-flares. Womabili enziwe ngesimo sezakhiwo ezingenamthungo. Amapayipi ethusi asetshenziswa ekufakeni amapayipi, i-HVAC, ekuqandisweni, ekuhlinzekweni kwegesi yezokwelapha, ezinhlelweni zomoya ocindezelwe kanye nezinhlelo ze-cryogenic. Ngaphezu kwamapayipi ethusi avamile, amapayipi akhethekile e-alloy nawo ayatholakala.
Amagama asetshenziswa ngamapayipi ethusi awaguquguquki ngandlela thile. Uma umkhiqizo ugoqiwe, ngezinye izikhathi ubizwa ngokuthi amapayipi ethusi ngoba wengeza ukuguquguquka futhi uvumela ukuthi izinto zigoqwe kalula. Kodwa lo mehluko awuyona neze umehluko owamukelwayo noma owamukelwayo. Futhi, amanye amapayipi ethusi aqinile odongeni aqondile ngezinye izikhathi abizwa ngokuthi amapayipi ethusi. Ukusetshenziswa kwala magama kungahluka kumthengisi nomthengisi.
Wonke amapayipi ayafana ngaphandle komehluko wobukhulu bodonga, lapho i-K-tube inezindonga ezijiyile kakhulu ngakho-ke inesilinganiso esiphezulu sokucindezela. Lawa mapayipi amancane ngo-1/8″ kunobubanzi bangaphandle futhi atholakala ngobukhulu obusukela ku-1/4″ kuya ku-12″, womabili adonswe (aqinile) futhi afakwe i-anneal (athambile). Amapayipi amabili odonga ajiyile nawo angagoqwa abe ububanzi obujwayelekile obungamasentimitha angu-2. Izinhlobo ezintathu zinemibala ebhalwe ngumenzi: oluhlaza okotshani ku-K, oluhlaza okotshani ku-L, kanye nobomvu ku-M.
Izinhlobo K no-L zifanele ukusetshenziswa kwengcindezi njengemishini yomoya kanye nokulethwa kwegesi yemvelo kanye ne-LPG (K ngaphansi komhlaba, L ngaphakathi endlini). Zonke izinhlobo ezintathu zifanelekela ukuphakelwa kwamanzi ekhaya (uhlobo M luyathandwa), ukudluliselwa kukaphethiloli kanye namafutha (uhlobo L luyathandwa), izinhlelo ze-HVAC (uhlobo L luyathandwa), izinhlelo ze-vacuum nokuningi.
Amapayipi okudonsa amanzi, imfucuza kanye nomoya wokungenisa umoya anezindonga ezincane kanye nezilinganiso zokucindezela eziphansi. Atholakala ngobukhulu obujwayelekile kusukela ku-1-1/4″ kuya ku-8″ kanye nophuzi. Atholakala ngobude obuqondile obungamamitha angu-20, kodwa ubude obufushane buvame ukutholakala.
Amapayipi asetshenziselwa ukudlulisa amagesi ezokwelapha uhlobo K noma uhlobo L anezidingo ezikhethekile zokuhlanzeka. Uwoyela osetshenziselwa ukwenza amapayipi kumele ususwe ukuze uvimbele ukuthi angavuthi lapho kukhona umoya-mpilo nokuqinisekisa impilo yesiguli. Amapayipi avame ukuxhunywa ngamapulagi nezivalo ngemva kokuhlanza bese egcotshwa nge-nitrogen purge ngesikhathi sokufakwa.
Amapayipi asetshenziselwa ukupholisa umoya kanye nokuqandisa aboniswa ububanzi bangaphandle bangempela, okuyinto ehlukile kuleli qembu. Ubukhulu busukela ku-3/8″ kuya ku-4-1/8″ ekusikeni okuqondile kanye no-1/8″ kuya ku-1-5/8″ kuma-coil. Ngokuvamile, la mapayipi anesilinganiso sokucindezela esiphezulu sobubanzi obufanayo.
Amapayipi ethusi atholakala ngama-alloy ahlukahlukene ukuze kusetshenziswe okukhethekile. Amapayipi ethusi e-beryllium angasondela emandleni amapayipi ensimbi, futhi amandla awo okukhathala awenza abe usizo kakhulu ekusetshenzisweni okukhethekile njengamapayipi e-Bourdon. I-alloy yethusi-nickel imelana kakhulu nokugqwala emanzini olwandle, futhi amapayipi avame ukusetshenziswa ezindaweni zasolwandle lapho ukumelana nokukhula kwe-barnacle kuyinzuzo eyengeziwe. I-Copper-Nickel 90/10, 80/20 kanye ne-70/30 amagama avamile ale nto. Amapayipi ethusi angenawo umoya-mpilo avame ukusetshenziswa kuma-waveguides nokunye okunjalo. Amapayipi ethusi ambozwe nge-titanium angasetshenziswa kuma-heat exchanger agqwalisayo.
Njengoba kushiwo ngaphambili, amapayipi ethusi axhunywa kalula kusetshenziswa izindlela zokushisa ezifana nokushisela kanye nokufaka insimbi. Nakuba lezi zindlela zanele futhi zilungele ukusetshenziswa njengokuphakelwa kwamanzi asekhaya, ukushisa kubangela ukuthi ipayipi elidonsiwe lingene, okwehlisa izinga lokucindezela kwalo. Kunezindlela eziningana zemishini ezitholakalayo ezingashintshi izakhiwo zepayipi. Lezi zindlela zifaka phakathi izinto zokufaka i-flare, izinto zokufaka i-grooved, izinto zokufaka i-compression kanye nezinto zokufaka i-push. Lezi zindlela zokubopha ngemishini ziwusizo kakhulu ezimweni lapho ukusetshenziswa kwelangabi noma ukushisa kungaphephile. Enye inzuzo ukuthi ezinye zalezi zixhumanisi zemishini kulula ukuzisusa.
Enye indlela, esetshenziswa ezimweni lapho amagatsha amaningi kufanele aphume epayipini elifanayo eliyinhloko, ukusebenzisa ithuluzi lokukhipha ukuze kudalwe indawo yokukhipha ngqo epayipini. Le ndlela idinga ukunamathisela uxhumano lokugcina, kodwa ayidingi ukusetshenziswa kwezinto eziningi zokufaka.
Lesi sihloko sifingqa izinhlobo zamapayipi ethusi. Ukuze uthole ulwazi olwengeziwe ngeminye imikhiqizo, sicela ubheke eminye imihlahlandlela yethu noma uvakashele i-Thomas Sourcing Platform ukuthola imithombo engaba khona yokutholakala noma ukubuka imininingwane ethile yomkhiqizo.
