Pipeline pombi: oiri, gasi kana mvura inotorwa kubva pasi inotakurwa ichiendeswa kuindasitiri yemafuta negasi nepombi yepombi. Pombi yepombi inoumbwa nemhando mbiri dzepombi isina musono uye yakasungwa, pombi inopera ine magumo, ine shinda uye socket end; Iyo yekubatanidza modhi ndeye kupera welding, collar yekubatanidza, socket yekubatanidza uye zvichingodaro.
Pipeline pombi: mafuta, gasi kana mvura inotorwa kubva pasi inoendeswa kuindasitiri yemafuta negesi nepombi pombi. Welded pombi inobatanidzwa ne fused welding line pombi, kazhinji kureba kwakareba, kunogona kugutsa huwandu hwemushandisi, asi kugadzikana. haina kunaka sehuremu humwechete hwakasanganiswa hwechubhu isina musono, asi kazhinji ipfupi pakureba kwechubhu isina musono, haigone kugutsa mutengi kushandiswa kwedaro refu, mutengi ari kushandiswa anofanira kuita collocation shandisa ese ari maviri. mhando mbiri dzepombi isina musono uye yakashongedzwa, iyo pombi inopera ine magumo, ine shinda uye socket yekupedzisira; Iyo yekubatanidza modhi ndiyo yekupedzisira welding, collar yekubatanidza, socket yekubatanidza uye zvichingodaro.
Nekuvandudzwa kwepombi yesimbi ndiro tekinoroji uye kufambira mberi kwepombi yakashongedzerwa kuumba, welding tekinoroji, kushandiswa kwepombi ine welded pombi mukuwedzera zvishoma nezvishoma, kunyanya mune yakakura dhayamita yakashongedzerwa pombi kirasi scope mukana wekunyorova, uye mutengo. zvinhu, welded pombi yave huru mumunda wemutsetse pombi, iyo inomisa kugadzirwa kwesimbi isina musono mutsetse wepombi.
API5L pombi yekugadzira pombi pari zvino iri kushandisa microalloying yekudziya yekurapa maitiro, simbi isina musono pombi yekugadzira mutengo wakakwira zvakanyanya kupfuura iyo welded pombi, uye nekuvandudzwa kwegiredhi resimbi, senge X80 simbi giredhi pombi pamuganho wekabhoni yakaenzana, iyo yakajairika maitiro. yesimbi isina musono pombi yakaoma kuzadzisa zvinodiwa nemushandisi
Transmission simbi pombi yakakamurwa kuva PSL1, PSL2 maviri chigadzirwa mamakisi, musiyano mukuru ndewekuti PSL2 ichienzaniswa nePSL1 pane kabhoni yakaenzana, kutsemuka kuomarara, kusimba kwegoho rakakura uye kusimba kwesimba rinodiwa.Kudzora kwezvinhu zvinokuvadza zvakaita sephosphorus nesarufa zvakare Kuomesesa.Kuedza kusingaparadzi kwemachubhu asina musono kunosungirwa.Zviri mukati mewaranti uye kuteedzera mushure mekuedza zvinosungirwa.
Izvo zvinonyanya kuita zvinodiwa zvemafuta uye gasi mapaipi esimbi zvinosanganisira:
1. Simba: Iyo yakawanda yemafuta uye gasi pombi inogadzirwa zvinoenderana nekusimba kwegoho resimbi. Mapaipi ane goho repamusoro simba anogona kushingirira kushanda kwakanyanya.
2. Kuomarara: Kusimba kwepamusoro kwepombi yesimbi kunogona kuunza mwero wakaderera weoiri uye gasi pombi yekuputika tsaona, saka API 5L inotaura kuti, pamusoro pezvakajairwa zvivakwa zvemuchina, v-notch Charpy kukanganisa bvunzo uye kudonha sando kubvarura bvunzo inofanira kuwedzerwa, uye pombi yesimbi inofanira kuva yakasimba nondestructive bvunzo isati yabuda mufekitari.
3. Weldability: Nekuda kwenzvimbo yakaoma yemunda yekuisa mapaipi, yakanaka weldability inodiwa panguva yebutt welding yepombi dzesimbi. Mapaipi ane low weldability achave nekutsemuka pamusono wewelding panguva yekushongedza, izvo zvichawedzera kuoma uye kusimba kweiyo welding seam. uye nzvimbo inopisa-inopisa, uye kuwedzera mukana wekuputika kwepombi.Nheyo yekugadzirwa kwesimbi weldability ndiyo kutonga kwemartensite transition point uye kuoma.Maererano nerubatsiro rwezvinhu zvealloying pane martensite transition point uye ruzivo runoshanda, calculation formula ye kabhoni yakaenzana inogona kushandiswa kuongorora weldability yesimbi.Kazhinji, iyo kabhoni yakaenzana inofanira kudzorwa pazasi 0.4%. Muchokwadi, mazhinji masimbi esimbi anodzorwa pazasi 0.35%.
4. Ductility: Kana iyo ductility isingakwani, ichaita kuti pave nekugadzirwa kweplate yesimbi inotsemuka panguva yekutonhora kwekukotama kana cambium fracture panguva ye welding.Naizvozvo, API standard ye welded pipe kunze kweiyo yakatarwa flattening test, asiwo inoda mutengi anotungamirirwa. kutonhora kwekukotama bvunzo.Chinokosha chekuvandudza ductility ndechekuderedza zvisiri zvesimbi inclusions musimbi uye kutonga morphology uye kugovera inclusions.
5. Corrosion resistance: kana uchiendesa sulfur oiri negasi, hydrogen sulfide necarbon dioxide mumvura zvinozoita kuti hydrogen embrittlement uye stress corrosion cracking yemachubhu esimbi. Matanho akadai sekudzora sulfur content, kudzora sulfide form uye kunatsiridza kuoma kwemadziro generally adopted.Iyo huru maitiro ndeye microalloying uye inodzorwa rolling, iyo inogona kuwana yakakwirira simba, yakakwirira kuomarara, yakakwira plastiki uye yakanaka weldability pasi pemamiriro ekupisa anokungurukira.Kuitira kuzadzisa zvizere zvinodikanwa zvekushanda kwemafuta uye gasi mapaipi esimbi, yakasimba alloy dhizaini. , sarufa, phosphorous uye zvimwe zvinokuvadza zvinhu zvakare zvakanyanya kuomarara control.Kazhinji, sarufa isingasviki 0.01% kuvandudza mapurasitiki uye kuoma kwesimbi, kunyanya iyo yakachinjika kuoma.
Application
Iyo pombi inoshandiswa kutakura oiri, chiutsi uye mvura inodhonzwa kubva pasi kuenda kumabhizinesi emafuta negasi indasitiri kuburikidza nepombi.
