Mapaipi esimbi asina musono

Mapaipi esimbi asina musono anogadzirwa nechidimbu chesimbi, uye hapana seam pamusoro. Dzinonzi seamless simbi mapaipi. Zvinoenderana nemaitiro ekugadzira, mapaipi asina musono akakamurwa kuita mapaipi anopisa-akakungurutswa, anotonhora-akakungurutswa pombi, inotonhora-inodhonzwa pombi, extruded pombi, jacking pombi, etc. Zvinoenderana neyakachinjika-chikamu chimiro, isina musono pombi dzesimbi dzakakamurwa kuita denderedzwa uye mapaipi akasarudzika. Mapaipi akasarudzika ane sikweya, oval, triangle, hexagon, mhodzi yemavise, nyeredzi, mapaipi ane mapapiro uye mamwe akawanda maumbirwo akaomarara. Iyo yakakura dhayamita i650mm uye dhayamita shoma ndeye 0.3mm. Zvinoenderana nekushandiswa kwakasiyana, kune mapaipi akakomberedzwa akakora uye mapaipi akatetepa. Mapombi esimbi asina musono anonyanya kushandiswa se petroleum geological drilling pombi, kupaza mapaipi epetrochemicals, boiler pombi, mapombi anotakura, uye yakakwirira-chaiyo simbi yekugadzira mapaipi emotokari, matirakita, uye nendege. Pombi yesimbi isina misono padivi pechikamu chemuchinjikwa wayo. Zvinoenderana neyakasiyana nzira dzekugadzira, yakakamurwa kuita mapaipi anopisa-akakungurutswa, anotonhora-akakungurutswa pombi, inotonhora-inodhonzwa pombi, extruded pombi, jacking pombi, nezvimwewo, zvese zvine yavo yemaitiro mirairo. Zvishandiso zvinosanganisira zvakajairwa uye zvemhando yepamusoro kabhoni structural simbi (Q215-A~Q275-A uye 10 ~ 50 simbi), yakaderera alloy simbi (09MnV, 16Mn, nezvimwewo), alloy simbi, stainless acid-resistant simbi, etc. Maererano. Kushandiswa, yakakamurwa kuita yakajairika kushandiswa (inoshandiswa semvura, gasi mapaipi uye zvimiro zvikamu, mechaniki zvikamu) uye yakakosha kushandiswa (inoshandiswa kune boilers, geological exploration, bearings, acid resistance, etc.). ① Huru yekugadzira nzira yekupisa-yakakungurutswa isina musono pombi (△ Main yekuongorora maitiro):
Pombi kugadzirira nekuongorora →Kuchengetera zvinhu
② Huru yekugadzira nzira yekutonhora-yakakungurutswa (yakadhonzwa) isina musono pombi yesimbi: Seamless simbi pombi_Seamless simbi pombi mugadziri_Seamless simbi pombi mutengo
Kugadzirira kusina chinhu →Kunhonga asidhi nekuzora → Kukungurutswa nechando (kudhirowa) → Kurapa nekupisa → Kururamisa → Kupedza → Kuongorora
General seamless simbi pombi yekugadzira maitiro anogona kukamurwa kuita inotonhora yekudhirowa uye inopisa kukunguruka. Iyo nzira yekugadzira inotonhora-yakakungurutswa seamless simbi pombi inowanzoomesesa pane inopisa kukungurutswa. Iyo pombi isina chinhu inofanira kutanga yakakungurutswa nematatu ma rollers, uyezve saizi bvunzo inofanira kuitwa mushure meextrusion. Kana pasina mhinduro yakatsemuka pamusoro, pombi yakatenderedzwa inofanira kuchekwa nemuchina wekucheka uye kutemwa mubillet inoita mita imwe pakureba. Zvadaro pinda annealing process. Anealing inofanira kusanganiswa nemvura ine acidic. Paunenge uchinhonga, teerera kana paine huwandu hukuru hwemabhuru pamusoro. Kana pane hukuru hwemabhubhu, zvinoreva kuti hutano hwepombi yesimbi hahukwanisi kuenderana nemitemo. Pachitarisiko, pombi dzesimbi dzisina musono dzinotonhora dzakapfupika pane pombi dzesimbi dzisina musono dzinopisa. Ukobvu hwemadziro epombi dzesimbi dzisina musono dzinotonhora kazhinji idiki pane dzepombi dzesimbi isina musono dzinopisa, asi pamusoro pacho panoratidzika kupenya kupfuura pombi dzakakobvu- dzakakomberedzwa nesimbi isina musono, uye pasi haina kushata, uye dhayamita harina. mabhura akawanda.
Mamiriro ekutumira epombi dzesimbi dzisina musono dzinopisa-dzinopisa uye dzinogadziriswa kupisa isati yasununguka. Mushure mekuongororwa kwemhando, pombi dzesimbi dzinopisa-dzakaputirwa dzinofanirwa kunyatsosarudzwa nemaoko nevashandi, uye nzvimbo yacho inofanirwa kuzorwa mafuta mushure mekuongororwa kwemhando, ichiteverwa neakawanda anotonhora ekudhirowa bvunzo. Mushure mekupisa kupisa kurapwa, bvunzo dzeperforation dzinofanirwa kuitwa. Kana iyo perforation dhayamita yakakurisa, kutwasanudza uye kururamisa kunofanira kuitwa. Mushure mekutwasanuka, mudziyo wekutakura unozoendeswa kune chinokanganisa kuti uone kukanganisa, uye pakupedzisira wakanyorwa, wakarongedzwa mune zvakatemwa, uye woiswa mudura.
Round chubhu billet → kudziyisa → perforation → matatu-roller oblique rolling, kuramba achiumburuka kana extrusion → chubhu kubviswa → saizi (kana kudzikisa dhayamita) → kutonhora → kutwasanudza → hydraulic pressure test (kana kuona kukanganisa) → kumaka → kuchengetedza pombi yesimbi isina musono inogadzirwa yesimbi ingot kana yakasimba chubhu billet nekuboora muchubhu yakakasharara, yozoitwa nekukunguruka kunopisa, kukunguruka kutonhora kana kudhirowa kutonhora. Izvo zvinotsanangurwa zvesimbi isina musono pombi zvinoratidzwa mumamirimita ekunze dhayamita * madziro ukobvu.
Iyo dhayamita yekunze yekupisa-yakakungurutswa isina musono pombi kazhinji yakakura kupfuura 32mm, uye ukobvu hwemadziro ndeye 2.5-200mm. Iyo dhayamita yekunze yepombi yesimbi isina musono inotonhora inogona kusvika 6mm, ukobvu hwemadziro hunogona kusvika 0.25mm, uye dhayamita rekunze repombi yakatetepa-yakakomberedzwa inogona kusvika 5mm uye ukobvu hwemadziro husingasviki 0.25mm. Cold rolling ine yakakwira dimensional accuracy pane inopisa kukunguruka.
Kazhinji, mapaipi esimbi asina musono anogadzirwa negumi, 20, 30, 35, 45 emhando yepamusoro kabhoni simbi, 16Mn, 5MnV uye mamwe akaderera-alloy maumbirwo simbi kana 40Cr, 30CrMnSi, 45Mn2, 40MnB nemamwe masimbi alloy. Kupisa kukunguruka kana kutonhora kukunguruka. Mapombi asina musono akagadzirwa neakaderera kabhoni simbi senge gumi ne20 anonyanya kushandiswa kuburitsa mapombi emvura. Mapombi asina musono akagadzirwa nepakati kabhoni simbi senge 45 uye 40Cr anoshandiswa kugadzira mekiniki zvikamu, senge zvinotakura zvinotakura zvikamu zvemotokari nematirakita. Kazhinji, mapaipi esimbi asina musono anofanirwa kuve nechokwadi chekusimba uye kufefetera bvunzo. Mapaipi esimbi anopisa anounzwa munzvimbo dzinopisa kana kuti dzinopisa; pombi dzesimbi dzinotonhora dzinounzwa munzvimbo dzinopisa.
Kupisa kunopisa, sezvinoreva zita, kune tembiricha yakakwira yechidimbu chakatenderedzwa, saka iyo deformation kuramba idiki uye yakakura deformation yakawanda inogona kuwanikwa. Tichitora kukungurutswa kwemahwendefa esimbi semuenzaniso, ukobvu hweinoramba ichikanda billet kazhinji hunenge 230mm, uye mushure mekukunguruka nekupedzwa kupetwa, ukobvu hwekupedzisira i1 ~ 20mm. Panguva imwecheteyo, nekuda kwediki hupamhi-ku-ukobvu reshiyo yendiro yesimbi, iyo dimensional kunyatsoita zvinodiwa zvishoma, uye hazvisi nyore kuva nezvinetso zvechimiro cheplate, kunyanya kudzora convexity. Kune avo vane zvinodiwa nesangano, kazhinji inowanikwa kuburikidza nekudzora kutenderedzwa uye kudzorwa kutonhora, ndiko kuti, kudzora tembiricha yekutanga kukunguruka uye tembiricha yekukunguruka kwekupedzisira kwekukunguruka. Round chubhu billet → kudziyisa → kuboora → musoro → kupinza → pickling → kuzora (copper plating) → akawanda anopfuura einotonhora kudhirowa (inotonhora kukunguruka) → billet chubhu → kupisa kupisa → kutwasanura → kudzvanywa kwemvura bvunzo (kuona kukanganisa) → kumaka → kuchengetedza.
