Seamless steel chubhu isimbi yakatenderedzwa, yakaenzana, ine rectangular ine mhango chikamu uye isina machubhu akaitenderedza.Machubhu esimbi asina musono anogadzirwa ne ingots kana kuti solid billets akabooborwa mu capillary chubhu uye ipapo inopisa inokungurutswa, inotonhora inokungurutswa kana kutonhora.

Seamless simbi pombi ine mhango chikamu, nhamba huru yepombi dzinoshandiswa kutakura zvinwiwa, Mukukotama uye torsion simba panguva imwe chete,Kuenzanisa simbi pombi nesimbi yakatenderera uye imwe yakasimba simbi.simbi pombi huremu huremu, imhando yehupfumi. chikamu chesimbi, chinoshandiswa zvakanyanya mukugadzirwa kwezvikamu zvezvimiro uye zvikamu zvemakanika, senge oiri yekuchera simbi scaffolding.

Seamless steel tube production ine nhoroondo yemakore anoda kusvika 100. Hama dzeGermany Manismann dzakatanga kugadzira two-roll cross-rolling punch muna 1885, ndokuzogadzira periodic pipe rolling machine muna 1891, uye Swiss RCStiefel yakagadzira otomatiki pombi inotenderedza muchina. inozivikanwawo seyepamusoro pombi yekukungurutsa muchina) muna 1903, nemichina yakasiyana-siyana yekuwedzera, senge pombi inotenderedza muchina uye muchina wekusunda pombi, wakatanga kuumba indasitiri yemazuva ano isina musono yechubhu.Mumakore ekuma1930, chigayo chepombi chetatu chakagamuchirwa.

Extrusion press uye periodic cold rolling mill inovandudza kusiyana uye kunaka kwemachubhu esimbi.Mumakore ekuma1960, nekuda kwekuvandudzwa kwechigayo chepombi inoenderera mberi, kubuda kwetatu-roll punch, kunyanya kubudirira kwekushandiswa kwemashini ekuderedza kushushikana uye kuenderera mberi. casting billet, yakavandudza kugadzirwa kwakanaka uye kwakawedzera kukwikwidza kwepombi isina musono uye pombi yakakandwa.

Mumakore ekuma1970, pombi isina musono uye pombi yakakandwa zviri kuramba zvichifambirana, uye kubuda kwepombi yesimbi pasi rose kuri kuwedzera neinodarika 5% pagore. Kubva 1953, China yakakoshesa zvikuru kusimudzira indasitiri yesimbi isina musono. yakatanga kugadzira nzira yekugadzira yekukungurutsa mapaipi akasiyana-siyana makuru, epakati uye madiki. Kazhinji, pombi yemhangura inotorawo nzira yebillet cross rolling uye perforation, pombi mill rolling. uye kudhirowa coil.

Applicationuye kupatsanurwa kwemachubhu esimbi asina musono

Chishandiso: Seamless simbi chubhu imhando yehupfumi chikamu simbi, ine chinzvimbo chakakosha muhupfumi hwenyika, inoshandiswa zvakanyanya mupetroleum, indasitiri yemakemikari, bhairi, chiteshi chemagetsi, ngarava, kugadzira michina, mota, ndege, aerospace, simba, geology. , zvikamu zvekuvaka uye zvehondo.

Classification:

(1) Zvinoenderana nechimiro chechikamu chakakamurwa kuita: denderedzwa chikamu chubhu, yakakosha-yakaumbwa chikamu chubhu

(2) maererano nezvinhu: kabhoni simbi pombi, alloy simbi pombi, Stainless simbi pombi, composite pombi

(3) Zvinoenderana neiyo nzira yekubatanidza: threaded yekubatanidza pombi, welding pombi

(4) Zvinoenderana nemaitiro ekugadzira: kupisa kutenderedza (extrusion, kumusoro, kuwedzera) pombi, kutonhora kutenderedza (dhonza) pombi.

(5) Zvinoenderana nekushandiswa: boiler pombi, pombi yemafuta pombi, pombi pombi, pombi yekugadzira, pombi yefetereza.

Seamless simbi chubhu kugadzira maitiro

Huru yekugadzira nzira yekupisa-yakakungurutswa seamless simbi chubhu (main inspection process):

Kugadzirira uye kuongororwa kwepombi billet → kupisa kwepombi billet → perforating → kukungurutsa pombi → kudzoreredza pombi isina chinhu → kugadzirisa (kuderedza) dhayamita → kupisa kupisa → kutwasanura pombi yapera → kupedza → kuongorora (isingaparadzi, muviri uye kemikari, kuongorora chiteshi) → warehousing

(2) Cold rolling (kudhirowa) isina musono simbi pombi kugadzirwa muitiro

Kugadzirira billet → kunhonga nekuzora → kutonhora kukunguruka (kudhirowa) → kupisa kupisa → kutwasanura → kupedza → kuongorora

Iyo yekugadzira inoyerera chati yekupisa-yakakungurutswa seamless simbi chubhu ndeiyi inotevera:
