Imiba engundoqo yokuMakisha
Iya kuphawulwa ngokucacileyo:
igama lomenzi okanye uphawu
inombolo yenkcazo,ibakala
igama kunye nenombolo ye-odolo yomthengi
kushushu okanye kubanda.
Qaphela: Ukumakishwa akufuneki kuquke umhla wonyaka wolu luhlu.
Ngeityhubhu ezingaphantsi ko-11/4ngaphakathi [31.8 mm] ububanzi kunye neetyhubhu ezingaphantsi kwe-3 ft [1 m] ubude, ulwazi olufunekayo lunokuphawulwa kwithegi eqhotyoshelwe ngokukhuselekileyo kwi-bundle okanye ibhokisi apho iityhubhu zithunyelwa khona.
ULungiselelo olongezelelweyo
Xa kuthengwa kwaye kusetyenziswa umbhobho we-ASTM A192, indawo yokusetyenziswa kokuphela kunye neemfuno ezithile zomsebenzisi zinokufuna ukuqhutyelwa phambili okongezelelweyo:
Ipeyinti okanye iCoating
Ipeyinti engangenwa ngumhlwa okanye ezinye izinto zokukhusela zingafakwa kumphezulu.Ezi zambatho zibonelela ngokhuseleko oluthile ekudlekeni, ngakumbi ukuba ityhubhu yebhoyila ibonakaliswe kukufuma.
Amayeza okulwa nomhlwa
Ukongeza kwipeyinti, ezinye iindlela zonyango ezichasene ne-corrosion ezifana ne-galvanizing, i-aluminizing, okanye i-coating kunye nezinye izinto ezichasene ne-corrosion zingasetyenziswa ukunceda ukwandisa ukuqina kombhobho kwiindawo ezinzima.
Unyango lobushushu
Nangona i-ASTM A192 ichaza iimfuno zokwenziwa kunye novavanyo lombhobho, kwezinye izicelo unyango olongezelelweyo lobushushu (umzekelo, ukunyanzeliswa, ukufakwa kwe-annealing) kunokufuneka ukuphumeza iipropati ezithile zoomatshini okanye ukuphucula i-microstructure yombhobho.
Umphezulu wangaphakathi nowangaphandle uyaGqibela
Umphezulu wangaphakathi nangaphandle weityhubhu zebhoyila unokufuna ukugutywa, ukukhazimliswa, okanye ukucocwa ukuze kuphuculwe iimpawu zokuqukuqela kwamanzi okanye ucoceko.
Ukuphelisa oomatshini
Ngokuxhomekeke kwiimfuno zofakelo kunye noqhagamshelo, iziphelo zeetyhubhu zebhoyila zingadinga ukuxutyushwa, i-chamfered, okanye ngenye indlela umatshini ukuququzelela ukufakwa.
UHlolo olongezelelweyo
Ukuqinisekisa ukuba iibhubhu ziyahlangabezana ne-ASTM A192 kunye neemfuno ezikhethekileyo kumthengi, uhlolo olongezelelweyo lunokwenziwa.Ngokomzekelo, uvavanyo lwe-ultrasonic, uvavanyo lwe-X-ray, njl.
Isicelo esikhethekileyo
Ubuchwephesha kwibhoyila yentsimbi yekhabhoni engenamthungo kunye neetyhubhu zeheater.Ezi zityhubhu zisetyenziselwa kakhulu iinkonzo zoxinzelelo oluphezulu ezifana ne-boilers yoxinzelelo oluphezulu, i-ultra-high-pressure boilers, kunye nezixhobo ezisebenza kwiindawo eziphezulu zokushisa kunye noxinzelelo oluphezulu.
Oku kulandelayo kusetyenziswa umbhobho wentsimbi we-ASTM A192 ekusebenzeni:
Iibhoyili zoxinzelelo oluphezulu
Iityhubhu ze-ASTM A192 ezingenamthungo zifaneleke ngokukodwa ukwenza iityhubhu ze-superheater, iityhubhu zebhoyila yamanzi ashushu, ii-conduits zomphunga, iityhubhu ezinkulu zeflue, njl.Ngokuqhelekileyo zisetyenziswa kwizikhululo zamandla, izityalo zoshishino kunye nemigodi kunye nezixhobo zekhemikhali, ezisetyenziselwa ukuvelisa ukushisa okuphezulu kunye noxinzelelo oluphezulu lwe-steam.
Iibhoyili zoxinzelelo oluphezulu
Iityhubhu ze-ASTM A192 zisetyenziswa ngokubanzi kwi-ultra-high-pressure (edla ngokubizwa ngokuba ngamabhoyili aneengcinezelo zokusebenza ngaphezu kwe-9.8 MPa) izicelo.Ezi bhoyila zidla ngokusetyenziswa kwizikhululo zamandla amakhulu.
Izifudumezi ezinkulu kunye nezifudumezi
Ezi zixhobo eziphambili zebhoyili kwaye zisetyenziselwa ukunyusa izinga lokushisa lomphunga, okwandisa ukufudumala kwenkqubo yonke.
Izitshintshi zobushushu
Nangona i-ASTM A192 isetyenziselwa ubukhulu becala kwiityhubhu zebhoyila, ingasetyenziselwa ukutshintshiselana kobushushu apho iipropati ezifanelekileyo zokutshintshwa kobushushu zifunekayo, ngakumbi kwiindawo eziphakamileyo zokushisa, eziphakamileyo.
Iibhoyila zeoyile ezishushu
Kolu hlobo lwebhoyila, amandla ashushu ahanjiswa ngokufudumeza ioyile eshushu, esetyenziswa ngokuqhelekileyo kwimichiza, ekusetyenzweni kokutya, nakwimizi-mveliso yelaphu.I-astm a192 tubing ilungele ubushushu obuphezulu, iimeko zoxinzelelo oluphezulu ezifumaneka kwezi zicelo.
