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 steel.steel pombi uremu iri chiedza, imhando yehupfumi chikamu chesimbi, chinoshandiswa zvakanyanya mukugadzirwa kwezvikamu zvemukati uye zvidimbu zvemichina, senge oiri yekuchera simbi yekupeta.

Seamless steel tube production ine nhoroondo yemakore anoda kusvika 100. Hama dzekuGermany Manismann dzakatanga kugadzira two-roll-cross-rolling punch muna 1885, ndokugadzira periodic pipe rolling machine muna 1891, neSwiss RCStiefel yakagadzira otomatiki pombi inokunguruka (inozivikanwawo seyepamusoro pombi inotenderedza muchina, semichina 190 inomonereka) nemuchina we190 unoramba uchitenderedza. muchina wekusunda pombi, wakatanga kuumba indasitiri yemazuva ano isina musono yechubhu.Mumakore ekuma1930, chigayo chepombi chetatu chakagamuchirwa.

Muma1960, nekuda kwekuvandudzwa kwepombi yepombi inoenderera, kubuda kwetatu-roll punch, kunyanya kubudirira kwekushandiswa kwemuchina wekudzikisa kushushikana uye kuenderera mberi kwekukanda billet.

Mumakore ekuma1970, pombi isina musono uye pombi yakakandwa zviri kuramba zvichifambirana, uye nyika yepasirese pombi pombi inobuda iri kuwedzera neanopfuura 5% pagore.Kubva muna 1953, China yakabatanidza kukosha kukuru pakusimudzira indasitiri isina musono simbi chubhu, uye pakutanga yakagadzira hurongwa hwekugadzira hwekukungurutsa hukuru, hwepakati nediki pombi. 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, ndege, simba, geology, kuvaka uye mauto zvikamu.

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 → kutenderedza pombi → kudzoreredza kwepombi isina chinhu → kugadzirisa (kuderedza) dhayamita → kupisa kupisa → kutwasanura pombi yapera → kupedza → kuongorora (kusingaparadzi, muviri uye kemikari, kuongorora chiteshi) → kuchengetera zvinhu

(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:
