Zvinoenderana nekugadzira nzira, mapaipi esimbi anogona kukamurwa kuita mapoka maviri: seamless simbi mapaipi uye welded simbi pombi.Pakati pazvo, ERW simbi mapaipi ndiwo mhando huru yemapombi esimbi akasungwa.Nhasi, tinonyanya kutaura pamusoro pemhando mbiri dzepombi dzesimbi dzinoshandiswa sekese yemidziyo: isina musono pombi dzepaipi uye ERW casing pombi.
Seamless casing pombi - casing pombi yakagadzirwa nesimbi isina musono pombi;Seamless steel pombi zvinoreva pombi yesimbi inogadzirwa nenzira ina dzekumonera kupisa, kukunguruka kunotonhora, kudhirowa kunopisa uye kudhirowa kunotonhora.Muviri wepombi pachawo hauna ma welds.
ERW body – ERW (Electric Resistant Weld) pombi yesimbi yakagadzirwa nemagetsi welded pombi inoreva musono wepaipi wakaiswa welding inogadzirwa nehigh frequency resistance welding.Mashizha esimbi mbishi (makoiri) emagetsi-welded pombi anogadzirwa kubva pasi-carbon micro-alloy simbi yakakungurutswa neTMCP (thermomechanical controlled process).
1. OD kushivirira seamless simbi pombi: uchishandisa inopisa-yakakungurutswa kuumba maitiro, saizi inopedzwa panenge pa8000 ° C.Kuumbwa kwezvinhu zvakasvibirira, mamiriro ekutonhora, uye kutonhora kwemupumburu kune simba guru padhayamita yaro yekunze, saka zvakaoma kunyatso kudzora dhayamita yekunze, uye chiyero chekuchinja chakakura.ERW simbi pombi: inoumbwa nekukotama kunotonhora, uye dhayamita yaro inoderedzwa ne0.6%.Iyo tembiricha yemaitiro inongogara patembiricha yekamuri, saka iyo dhayamita yekunze inodzorwa nemazvo, uye shanduko yemhando idiki, iyo inobatsira kubviswa kwematehwe ematehwe matema;
2. Seamless simbi pombi ine madziro ukobvu kushivirira: Inogadzirwa ne perforating simbi yakatenderera, uye kutsauswa kwemadziro kwakakura.Kutevera kunopisa kupisa kunogona kubvisa zvishoma kusaenzana kwehukobvu hwemadziro, asi michina yemazuva ano inogona kungoigadzirisa mukati me ± 5 ~ 10% t.ERW simbi pombi: Paunenge uchishandisa inopisa yakakungurutswa coil seyakagadzirwa, kushivirira kwehukobvu hwemazuva ano inopisa inopisa inogona kudzorwa mukati me 0.05mm.
3. Kukanganisa kwekunze kwechishandiso chebasa chinoshandiswa pakuonekwa kwepombi yesimbi isina musono haigone kubviswa mukupisa kunopisa, asi inogona kukwenenzverwa mushure mekunge chigadzirwa chapedzwa, helical stroke yakasara mushure mekurovera inogona kungobviswa zvishoma mukuderedza madziro.ERW simbi pombi inogadzirwa kubva inopisa yakakungurutswa coil seyakagadzirwa.Hunhu hwepamusoro hwekoiri hwakafanana nepamusoro pemhando yeERW simbi pombi.Hunhu hwepamusoro hwemakoiri anopisa akakungurutswa ari nyore kudzora uye ndeemhando yepamusoro.Naizvozvo, kunaka kwepamusoro kweERW simbi pombi iri nani kupfuura iyo yepombi yesimbi isina musono.
4. Oval seamless simbi pombi: kushandisa inopisa rolling process.Iyo yakasvibirira yakaumbwa yepombi yesimbi, mamiriro ekutonhora uye kutonhora mamiriro emupumburu ane simba guru padhayamita yaro yekunze, saka zvakaoma kunyatso kudzora dhayamita rekunze, uye chiyero chekuchinja chakakura.ERW simbi pombi: inogadzirwa nekutonhora kukotama, iyo dhayamita yekunze inodzorwa nemazvo, uye shanduko yemhando idiki.
5. Tensile bvunzo Zvimiro zvesimbi isina musono pombi uye ERW simbi pombi inoenderana ne API miyero, asi simba resimbi isina musono pombi rinowanzova padanho repamusoro, uye ductility iri pamuganho wakaderera.Pane zvinopesana, indekisi yesimba yeERW simbi pombi iri mumamiriro akanakisa, uye indekisi yepurasitiki ndeye 33.3% yakakwira kupfuura chiyero.Chikonzero ndechekuti sechinhu chakasvibiswa cheERW simbi pombi, kushanda kwekoiri inopisa yakaputirwa kunovimbiswa ne-micro-alloy smelting, kunze-kwe-furnace kunatsa, uye kudzorwa kutonhora nekukunguruka;plastiki.Kusangana kunonzwisisika.
6. Iyo yakasvibirira yeERW simbi pombi inopisa-yakaputirwa coil, iyo ine yakanyanyisa kukwirira kwakanyatso kurongeka, iyo inogona kuve nechokwadi chekuita yunifomu yechikamu chimwe nechimwe chekoiri.
7. Raw material yeERW inopisa yakakungurutswa simbi coil pombi ine saizi yezviyo inotora yakafara uye gobvu inoenderera ichikandira billet, iyo yepamusoro-yezviyo solidification layer yakakora, hapana nzvimbo yecolumnar crystals, shrinkage porosity uye pores, kutsauka kwekuumbwa kudiki., uye chimiro chacho chakabatana;kudzora mune inotevera rolling process Kushandiswa kweinotonhora yekutenderedza tekinoroji inowedzera kuve nechokwadi saizi yezviyo zvezvakagadzirwa.
8. Kutsvedza kupikisa bvunzo yeERW simbi pombi inoenderana nehunhu hwezvinhu zvakasvibirira uye nzira yekugadzira pombi.Ukobvu hwemadziro kufanana uye ovality zviri nani kupfuura mapaipi esimbi asina musono, ndicho chikonzero chikuru chinoita kuti kudonha kumire kwakakwira kupfuura kwepombi dzesimbi dzisina musono.
9. Kuedzwa kwemhedzisiro Nekuda kwekuoma kwechigadziko cheERW simbi pombi yakakwira kakawanda kupfuura iyo yepombi yesimbi isina musono, kusimba kweweld ndiyo kiyi yeERW simbi pombi.Nekudzora zviri mukati metsvina muyakasvibira, kureba uye kwakanangana nekucheka burr, chimiro chemupendero wekugadzira, iyo welding angle, iyo welding yekumhanyisa, simba rekudziya uye frequency, iyo welding extrusion vhoriyamu, yepakati frequency yekudzosa tembiricha uye kudzika, kureba kwechikamu chekutonhora kwemhepo uye mamwe maitiro maparamita anovimbiswa.Energy weld impact inosvika kupfuura 60% ye base simbi.Nekuwedzera optimization, simba rekuita re weld rinogona kunge riri padyo nesimba resimbi yepasi, iyo inovimbisa kushanda pasina dambudziko.
10. Kuedza kunoputika Kuongorora kwekuputika kweERW simbi mapaipi akakwirira zvikuru kudarika zvinodiwa, kunyanya nekuda kwekufanana kwepamusoro kwemadziro emadziro uye dhayamita yekunze yakafanana yeERW simbi mapaipi.
