Nekuti iyo pombi yekufambisa inonyanya kukodzera kutakura oiri, gasi, saka, pombi mu petroleum uye petrochemical indasitiri yaishandiswa zvakanyanya.Aimbove petrifaction Corporation pagore crude oil 120000000 T, ainyanya kushandiswa nepombi;kugadzirwa kwegore negore kweutsi, marasha, dizeli mamiriyoni 5000 matani, ayo 80% ane pombi yekutakura;petrochemical enterprise mudziyo, mudziyo wemvura kana gaseous makemikari zvinhu zvekufambisa zvinonyanya kuburikidza nepombi yekupedzisa.Naizvozvo, petrochemical Enterprises gore negore kuvaka uye mukugadzira nekugadzirisa zvese zvinoda kushandisa nhamba yakakura yesimbi pombi.Asi, nekuda kweiyo petrochemical indasitiri basa inoratidzwa nekupisa kwakanyanya uye kudzvanywa kwepamusoro, kupisa uye kuputika, saka pakushandisa machubhu esimbi zvinoda kuomarara kwazvo.

Kuramba kwakanangawelding simbi pombidevelopment

Mumakore achangopfuura, kune pombi yepasirese yepamusoro-soro isina musono pombi yekutsiva iyo yakakwira mutengo wekusimudzira maitiro, zvakanyanya nekuda kweiyo welded pombi yekugadzira tekinoroji inogara ichibudirira, inoratidzwa mune zvinotevera zvinhu:

(1) tekinoroji yedesulfurization, kuitira kuti sarufa yemukati yesimbi ideredze, inovandudza kunaka kwekushongedza kwepombi yesimbi.

(2) vacuum degassing tekinoroji, inovandudza chubhu isina kuchena simbi, inoderedza inclusions, weld musono mhando inovandudza.

(3) nekuda kwekuwedzera kweV, Ti, Nb uye zvimwe zvakakosha zvinhu, inoderedza iyo kabhoni yakaenzana, kusimba kwesimbi, simba uye zvimwe zvivakwa zvinovandudzwa.

( 4) kuvandudzwa kwetambo yesimbi inopisa yekukungurusa tekinoroji, yakawedzera dimensional kunyatsoita, saka pombi saizi yekutsauka kuderedzwa.

(5) kuvandudzwa kwemhando dzekuongorora nzira, dzakadai seye ultrasonic nondestructive test, hydrostatic yekuongorora muchina uye mimwe michina inofanirwa kushandiswa, kuve nechokwadi chemhando yechigadzirwa chekupedzisira.

Yakatwasuka kuramba welding simbi pombi inoshandiswa mu petrochemical bhizinesi

Petrochemical mabhizinesi kusarudzwa kwepombi yesimbi nekuda kwekutakura kumwe kudzvanywa, inowanzo shandiswa mumvura ine musono pombi yesimbi.Electric resistance welded pombi uye fluid ine seamless simbi pombi kusiyana, ane pachena upfumi zvikomborero, kunyanya anoratidza mu: shoma mari;mechanization, automation degree yakakwira;yakaderera kugadzirwa kwesimba rekushandisa (yekamuri tembiricha kugadzira, uye isina musono simbi pombi yekudziya kana kutonhora kudhirowa kuumbwa);mari yekugadzira yakaderera, yesimbi isina musono chubhu inenge 2/3;kuenderera mberi kwekugadzirwa, kubereka goho repamusoro uye rakakwirira.Longitudinal welded pombi indasitiri muChina yakatanga muna 50′s, yakatanga kunonoka, kugadzirwa kwemaitiro uye tekinoroji uye nyika yakasimukira inofananidzwa, inoisa mutsauko mukuru kwazvo.Iyo yakawanda yebhizinesi tekinoroji michina kutadza, kushaikwa kweinodiwa nzira dzekuona, asiwo kune hurombo hwemhando yebhandi pfupi, yakatetepa seyakaomeswa, yakakonzera welded pombi zvigadzirwa zvine diki aperture, yakaderera kutakura simba, chimiro chechigadzirwa hachina musoro, chakasungwa. kugadzirwa kwepombi mu80% kunogona chete kushandiswa seyakadzika kudzvinyirira mvura inotakura marasha pombi yemvura, marudzi ese epombi yakakosha yakaderera chikamu.Rudzi urwu rwemichina yakaderera welding uye tekinoroji level, kugadzira iyo
