Iimvavanyo zoomatshini ezichaziweyo
- UVavanyo lweTension ye-Transverse okanye i-Longitudinal kunye noVavanyo lwe-Flattening, uvavanyo lobunzima, okanye uvavanyo lwe-Bend
- Ukufudumala kwezinto eziphathekayo kwisithando sohlobo lwe-batch, iimvavanyo ziya kwenziwa kwi-5% yombhobho kwiqashiso ngalinye eliphathwayo. Kwiiqashiso ezincinci, ubuncinane umbhobho omnye uya kuvavanywa.
- Ukushisa kwezinto eziphathwayo ngenkqubo eqhubekayo, iimvavanyo ziya kwenziwa kwinani elaneleyo lombhobho ukwenza i-5% yeqashiso, kodwa akukho meko ingaphantsi kwe-2 ipayipi.
Amanqaku oVavanyo lwe-Bend:
- 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 onedayamitha elingana okanye edlula i-NPS 10 unokunikwa uvavanyo lokugoba endaweni yovavanyo lokucaba ngokuxhomekeke ekuvunyweni komthengi.
- Imizekelo yokuvavanya i-bend iya kugotywa kwiqondo lokushisa lokushisa nge-180 ngaphandle kokuqhekeka ngaphandle kwesahlulo esigobileyo.
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 enobushushu obuphezulu equlethe isulfure.
