Carbon Simbi Seamless Pipe
Seamless Simbi Pipe inogadzirwa kubva kune yakasimba kutenderera simbi'billet'iyo inodziiswa nekusaidzirwa kana kudhonzwa pamusoro pechimiro kusvika simbi yaumbwa kuita chubhu isina mhango.Iyo pombi isina musono inozopedzwa kuita dimensional uye mudhuri ukobvu kutsanangurwa muhukuru kubva pa1/8 inch kusvika 32 inch OD.Carbon Steel Seamless Pipes / Tubes Carbon simbi ialloy ine iron uye kabhoni.Iko muzana yekabhoni musimbi inokanganisa kuoma, kusimba kwekusimba uye ductility yekabhoni simbi.Seamless kabhoni simbi pombi kana yakasimba simbi ingot inogadzirwa necapillary chubhu kuburikidza negomba, ipapo kuburikidza nekupisa-kukungurutswa, kutonhora kwakatenderedzwa kana kutonhora kunoitwa.Seamless kabhoni simbi pombi muChina simbi indasitiri ine chinzvimbo chakakosha.Seamless kabhoni simbi pombi zvinhu ichubhu yakatenderera, pombi yekucheka muchina embryos kuti ipfuure nekucheka ingangoita 1 m yekureba isina chinhu, uye inotumirwa neconveyor bhandi choto kupisa.Billet inodyiswa muchoto chekupisa, tembiricha inenge 1200 degrees Celsius.Mafuta ihydrogen kana acetylene.Kudzora tembiricha yevira ndiyo nyaya huru.Round chubhu yakabuda kuti irove nemuchina kuburikidza nemhepo.Kazhinji yakajairika punch ndeye tapered roll perforation muchina, iyo punch yakakwirira yekugadzira kunyatsoita, chigadzirwa mhando, yakakura dhayamita yekuwedzera gomba, inogona kupfeka akasiyana simbi.Perforation, round chubhu yanga iri pamatatu-roll cross rolling, rolling kana extrusion.Yakasvinwa kubva pachubhu mushure mekuita saizi.Kukura nekumhanya-mhanya koni inoboora maburi mubillet kuita chubhu.Pipe dhayamita nesaizi yeguyo kuona kureba kwedhayamita yedhiri.Mushure mepombi kuburikidza nekuyera mushongwe yekutonhora, kutonhora nepfapfaidzo yemvura, simbi mushure mekutonhodza, inofanirwa kutwasanudza.Mushure mebhandi resimbi rinotumirwa nekururamisa simbi yekuyedza muchina (kana kudzvanywa bvunzo) yekuedzwa kwemukati.Kana iyo pombi yemukati inotsemuka, mabhuru uye mamwe matambudziko achaonekwa.Mushure mepombi asiwo kuburikidza nekuomarara kwemhando yekudzora bhuku rekusarudza.Hunhu hwesimbi, kushandiswa kwenhamba dzependi yekupfapfaidza, zvakatemwa, nhamba yekugadzira yakawanda.Nekireni mudura.
