Yintoni i-ASTM A192?

I-ASTM A192:Inkcazo esemgangathweni yeeThubhu zeBoiler zentsimbi yeCarbon engenamthungo kwiNkonzo yoxinzelelo oluphezulu.

Le nkcazo igubungela ubuncinci bodonga lobunzima, ibhoyila yentsimbi yekhabhoni engenamthungo, kunye neetyhubhu zeheater enkulu yenkonzo yoxinzelelo oluphezulu.

I-ASTM A192 ipayipi yentsimbi engenamthungo

Amaqhosha okukhangela

ASTM A192 Ubungakanani Range

Ububanzi obungaphandle: 12.7-177.8mm1/2-7 ngaphakathi.]

Ubuncinane obukhulu bodonga: 2.2-25.4mm [0.085 -1in.]

Iityhubhu ezinomnye umlinganiselo zinokunikezelwa, ngaphandle kokuba iityhubhu ezinjalo zithobelana nazo zonke ezinye iimfuno zolu nkcukacha.

Ukwenziwa

Iityhubhu azinamthungo kwaye zishushu okanye zibandayo zisetyenzwe njengoko kusenziwa iNkqubo.

I-ASTM A192 zimbini iindlela eziphambili zokuvelisa umbhobho wentsimbi ongenamthungo: utsalwa ngokubanda kwaye ushushu uqengqiwe.

Unyango lobushushu

Ubushushu bunyangwa kwi-1200℉ [650℃] okanye ngaphezulu emva kwepaseji yokufunxa ebandayo yokugqibela.

Ukunyamezelwa kweDimensional

Izixhobo ezibonelelweyo ziya kuhlangabezana neemfuno ezifanelekileyo ze-ASTM A450.

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.

iityhubhu ze-astm a192

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:

astm a192 kwibhoyila carbon steel umbhobho

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 eziphezulu 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.
