Mumunda wemapaipi esimbi, zviyero zvearc welded straight seam simbi mapaipi akakosha.Imwe yezviyero ndeye GB/T3091-2008, iyo inovhara mhando dzakasiyana dzemapombi esimbi akatwasuka, akadai seyepamusoro-frequency kuramba.welded (ERW) simbi pombi, arc yakanyurawelded (SAWL) simbi pombiuye spiral seam yakanyura arc welded (SAWH) mapaipi esimbi.)Simbi Pipe.
Pakufambisa kwemvura yakaderera, GB/T3091-2008 inotaurawo kushandiswa kwepombi dzesimbi dzakakoshwa.Idzi dzemagetsi welded steel pombi, dzinowanzozivikanwa semapaipi chena, dzinoshandiswa kutakura mvura, gasi, mhepo, mafuta, kupisa chiutsi, mvura inodziya, etc. Izvo zvinotsanangurwa zvemapombi esimbi aya zvinoratidzwa mudhayamita yezita, uye dhayamita yekunze nemadziro. ukobvu kunoenderana nemirairo yeGB/T21835.Uyezve, kureba kwepombi yesimbi kunogona kubva pa300mm kusvika 1200mm, uye inogona kugadziriswa kureba kana kureba kaviri.
Kana zvasvika kunyaya dzemhando, tembiricha panguva yekuboora ine simba guru.Mapombi esimbi ekuwedzera anopisa anowanzo kusvika tembiricha dzakatenderedza 1200 ° C, kunyangwe kabhoni yemukati uye alloying zvinhu zvinogona kuderedza tembiricha zvishoma.Chimwe chinhu chakakosha chekufunga nezve kudzikisa huwandu hwechiyero panguva inopisa yekukotama, sezvo izvi zvichigona kukanganisa hupenyu hwechishandiso uye mhando yepasi.
Kupisa kushanda inzira yakakosha mukugadzirwa kwe16Mn yakatwasuka musono simbi pombi.Sezvo kuwanda kwekugadzirisa kunoitika munzvimbo inopisa, kunyatso kudzora tembiricha yekudziya kwakakosha kuve nechokwadi chemhando yechigadzirwa chekupedzisira.
Kuti uchengetedze mhando uye zviyero, kudzora tembiricha panguva yekuboora kugadzirisa kwakakosha.Iyo yakatwasuka musono simbi pombi standard GB/T3091-2008 inotsanangura zvinotenderwa kutsauka muhukuru, chimiro, huremu uye dhayamita rekunze uye ukobvu hwemadziro.Kutsauka kunotenderwa kweakamisikidzwa madziro ukobvu kunosiyana zvichienderana negiredhi rekutsaudzira, kubva paS1 kusvika kuS5, uye giredhi rega rega rinotsanangura inoenderana muzana uye kushoma kutsauka.
Pamusoro peiyo yakajairwa madziro ukobvu kushivirira, isina-yakajairwa madziro ukobvu kushivirira kunoonekwa zvakare.Kutsauswa mazinga (semuenzaniso NS1 kusvika NS4) anosanganisira chaiwo kubva muzana kutsauka kuti uve nechokwadi chekutonga kwemhando.Izvo zvinofanirwa kucherechedzwa kuti S inomiririra zita remadziro ukobvu hwepombi yesimbi, uye D inomiririra yezita rekunze dhayamita yepombi yesimbi.
Kuve nechokwadi chekutevedzera izvi zviyero zvakakosha pakugadzirwa kwemhando yepamusoro longitudinal yakanyura arc welded simbi mirwi mapaipi.Nekunyatso chengetedza tembiricha uye kuterera kune zvinotenderwa kutsauka, vagadziri vanogona kusangana nezvinodiwa nevatengi uye vanopa zvigadzirwa zvakavimbika uye zvinogara kwenguva refu.
