    Uvavanyo lweHydraustatic:

    Umbhobho weNtsimbi kufuneka uVavanywe ngokweHydraulically enye nenye. Uxinzelelo oluphezulu lovavanyo luyi-20 MPa. Ngaphantsi koxinzelelo lovavanyo, ixesha lokuzinzisa kufuneka lingabi ngaphantsi kwe-10 S, kwaye iPipe yensimbi akufanele ivuze.

    Emva kokuba uMsebenzisi eVumelana, uvavanyo lweHydraulic lunokutshintshwa luVavanyo lwangoku lwe-Eddy okanye uvavanyo lokuvuza kweMagnetic Flux.

    Uvavanyo olungonakaliyo:

    Imibhobho efuna uHlolo oluthe kratya kufuneka ihlolwe ngokwe-Ultrasonically nganye nganye. Emva kokuba uThetha-thethwano lufuna imvume yeQela kwaye luchazwe kwiKhontrakthi, olunye uvavanyo olungabhubhisi lunokongezwa.

    Uvavanyo lokucaba:

    Iityhubhu ezinoMda waNgaphandle oMkhulu kune-22 mm ziyakuBekelwa kuVavanyo lokuNcandwa. Akukho Kulahlwa okubonakalayo, amabala amhlophe, okanye ubumdaka obunokuthi kwenzeke ngexesha lovavanyo lulonke.

    Uvavanyo lokuqina:

    Ngombhobho wamaBanga P91, P92, P122, kunye no-P911, Brinell, Vickers, okanye iimvavanyo zokuqina zeRockwell ziya kwenziwa kumzekelo osuka kwindawo nganye.

    Uvavanyo lokugoba:

    Kumbhobho obubanzi bayo budlula i-NPS 25 kwaye ububanzi bayo bobungqingqwa bodonga yi-7.0 okanye ngaphantsi iya kufakwa kuvavanyo lokugoba endaweni yovavanyo lokucaba. Omnye umbhobho obubanzi bayo bulingana okanye obudlula i-NPS 10 unokunikwa uvavanyo lokugoba endaweni yovavanyo lokucaba ngokuxhomekeke kwimvume yomthengi.

    I-ASTM A335 P5 iityhubhu zentsimbi ezingenamthungo zilungele amanzi, umphunga, i-hydrogen, ioli emuncu, njl.; Xa isetyenziswa kwindawo yokusebenza efana neoyile emuncu, inobushushu obuphezulu bobushushu bokumelana nokukhula kwesulfure, kwaye ihlala isetyenziswa kwiimeko zobushushu obuphezulu be-sulphur corrosion ye-288 ~ 550.

    Inkqubo yokuvelisa:

    1. Ukuqengqeleka okushushu (ityhubhu yentsimbi ekhutshiweyo engenamthungo) : ityhubhu engqukuva yebillet → ukufudumeza → ukugqobhoza → ukuqengqeleka okunqamlezayo okuqengqelekayo okuqengqelekayo → ukuhluba ityhubhu → ukulinganisa (okanye ukunciphisa) → ukupholisa → ukolula → uvavanyo loxinzelelo lwamanzi (okanye ukufumanisa isiphene ) → ukuphawula → ugcino

    2. Umzobo obandayo (uqengqeleka) ityhubhu yentsimbi engenamthungo: ityhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukufakwa kwe-oyile (icwecwe lobhedu) → umzobo obandayo ohamba ngeendlela ezininzi (ukuqengqeleka okubandayo) → ityhubhu engenanto → unyango lobushushu → ukulungisa → amanzi uvavanyo loxinzelelo (uphawu lwesiphene) → ukuphawula → ugcino

    Iimeko zesicelo:

    Kwizixhobo ze-atmospheric kunye ne-vacuum yokusetyenzwa kwe-oyile ekrwada ephezulu yesulfure, i-ASTM A335 P5 iityhubhu zentsimbi ezingenamthungo zisetyenziswa ikakhulu kwimibhobho esezantsi ye-atmospheric kunye ne-vacuum tower, iityhubhu zesithando somlilo se-atmospheric kunye ne-vacuum furnaces, amacandelo anesantya esiphezulu se-oil conversion kunye ne-vacuum. imigca kunye neminye imibhobho yeoli kunye negesi ephezulu yobushushu equlethe isulfure.

    Kwiiyunithi ze-FCC, iityhubhu ze-ASTM A335 P5 ezingenamthungo zisetyenziswa ikakhulu kwi-slurry yobushushu obuphezulu, i-catalyst kunye ne-refining yokubuyisela imibhobho, kunye neminye imibhobho ye-oyile yesulfure ephezulu yobushushu kunye negesi.

    Kwiyunithi yokupheka okulibazisekayo, umbhobho wensimbi ongenamthungo we-ASTM A335 P5 usetyenziswa ikakhulu kumbhobho wokutyisa ubushushu obuphezulu ezantsi kwe-coke tower kunye nobushushu obuphezulu be-oyile kunye nombhobho wegesi kumphezulu we-coke tower, umbhobho womlilo osezantsi kwiziko le-coke, umbhobho kumbhobho we-coke. Umzantsi we-fracking tower kunye nolunye ubushushu obuphezulu be-oyile kunye nombhobho wegesi oqulethe isulfure.

     

    Umbhobho we-Alloy Steel uqulethe izinto ezininzi ngaphandle kwekhabhoni ezifana nenickel, chromium, isilicon, manganese, tungsten, molybdenum, vanadium kunye nezixa ezinyiniweyo zezinye izinto ezamkelwa ngokuqhelekileyo njengemanganese, isulfure, isilicon, kunye nephosphorous..

    I-ASTM A335 P9 yintsimbi yentsimbi engenamthungo yeferritic yobushushu obuphezulu bomgangatho waseMelika. ityhubhu ye-alloy luhlobo lwetyhubhu yentsimbi engenamthungo, ukusebenza kwayo kuphezulu kakhulu kunetyhubhu yentsimbi engenamthungo, kuba olu hlobo lwetyhubhu yentsimbi iqulethe ngaphezulu kwe-C, ukusebenza kungaphantsi kwetyhubhu yentsimbi engenamthungo, ngoko ke ityhubhu yealloyi isetyenziswa kakhulu. kwi-petroleum, i-aerospace, ikhemikhali, amandla ombane, ibhoyila, umkhosi kunye namanye amashishini.

    I-A335 P9 yintsimbi yobushushu obuphezulu be-chromium-molybdenum ekwazi ukumelana nobushushu obuveliswa ngokomgangatho waseMelika. Ngenxa yokumelana ne-oxidation ebalaseleyo, amandla aphezulu obushushu kunye nokumelana nomhlwa kwesulfide, isetyenziswa kakhulu kubushushu obuphezulu kunye noxinzelelo oluphezulu olunokutsha kunye nemibhobho eqhumayo yezityalo zokucoca i-petroleum, ngakumbi umbhobho wobushushu othe ngqo weziko lokufudumeza, ubushushu obuphakathi bunokufikelela kuma-550 ~ 600 ℃ .

    Intsimbi yealloy yasekhaya ehambelanayo: 1Cr5Mo GB 9948-2006 "Umgangatho wombhobho wentsimbi ongenamthungo wePetroleum Cracking"
