Kugadzirwa kwepombi yesimbi yakatanga kubva pakutanga kwema1800.Pakutanga, pombi yaigadzirwa nemaoko - nekudziisa, kukotama, kupeta, nekurova mipendero pamwechete.Yekutanga otomatiki yekugadzira pombi maitiro akaunzwa muna 1812 muEngland.Nzira dzekugadzira dzakaramba dzichivandudzwa kubva panguva iyoyo.Dzimwe nzira dzakakurumbira dzekugadzira pombi dzinotsanangurwa pasi apa.
Lap Welding
Kushandiswa kwelap welding kugadzira pombi kwakatangwa mukutanga kwema1920.Kunyange zvazvo nzira iyi isingachashandiswi, imwe pombi yakagadzirwa pachishandiswa lap welding process ichiri kushandiswa nanhasi.
Mukugadzira simbi pamakumbo, simbi yaidziiswa muchoto yobva yakungurutswa kuita silinda.Micheto yeplate yesimbi yakabva ya “scarfed”.Scarfing inosanganisira kuvhara mukati mependero yesimbi, uye tapered mupendero wepakatarisana neplate.Musono wacho wakabva waiswa welding pachishandiswa bhora rewelding, uye pombi yaipisa yaipfuudzwa pakati pema rollers izvo zvaimanikidza musono pamwe chete kugadzira chisungo.
Iwo welds anogadzirwa nelap welding haana kuvimbika seaya akagadzirwa achishandisa nzira dzemazuva ano.IAmerican Society of Mechanical Engineers (ASME) yakagadzira equation yekuverenga iyo inobvumirwa kushanda kumanikidza kwepombi, zvichienderana nerudzi rwekugadzira maitiro.Iyi equation inosanganisira shanduko inozivikanwa se "joint factor", iyo inobva pamhando ye weld inoshandiswa kugadzira musono wepombi.Mapaipi asina musono ane akabatana chinhu 1.0 Lap welded pombi ine akabatana chinhu 0.6.
Magetsi Resistance Welded Pipe
Magetsi anopokana akaiswa welded (ERW) pombi inogadzirwa nekutonhora-kuumba pepa resimbi kuita cylindrical shape.Ikozvino zvino inopfuudzwa pakati pemipendero miviri yesimbi kupisa simbi kusvika pane iyo mipendero inomanikidzwa pamwechete kuti iite chisungo pasina kushandisa welding filler zvinhu.Pakutanga iyi nzira yekugadzira yakashandisa yakaderera frequency AC ikozvino kupisa mipendero.Iyi low frequency process yakashandiswa kubva ku1920's kusvika 1970. Muna 1970, iyo yakaderera frequency process yakatsiviwa ne high frequency ERW process iyo yakagadzira yemhando yepamusoro weld.
Nokufamba kwenguva, mawelds epipe yakaderera ERW pombi yakawanikwa ichikwanisa kusarudzwa seam corrosion, hoko yakatsemuka, uye kusakwana kusungirirwa kweseams, saka yakaderera frequency ERW haichashandiswi kugadzira pombi.Iyo yakakwirira frequency process ichiri kushandiswa kugadzira pombi kuti ishandiswe mukuvaka pombi nyowani.
Electric Flash Welded Pipe
Magetsi flash welded pombi yakagadzirwa kutanga muna 1927. Flash welding yakazadzikiswa nekugadzira bepa resimbi kuita cylindrical shape.Micheto yaidziiswa kusvika yanyungudutswa, yozosungirirwa pamwe chete kusvikira simbi yakanyungudutswa yabuditswa kubva mujoini uye kuita bhedhi.Senge yakaderera frequency ERW pombi, seams eflash welded pombi inotapukirwa nekuora uye hoko yakatsemuka, asi kusvika padiki pane ERW pombi.Mhando iyi yepombi inogonawo kukanganisa kukundikana nekuda kwemavara akaoma muplate simbi.Nekuti ruzhinji rwe flash welded pombi yakagadzirwa nemugadziri mumwe chete, zvinotendwa kuti nzvimbo dzakaoma idzi dzakaitika nekuda kwekudzima netsaona kwesimbi panguva yekugadzira iyo inoshandiswa nemugadziri iyeye.Flash welding haichashandiswa kugadzira pombi.
Kaviri Submerged Arc Welded (DSAW) Pipe
Zvakafanana nedzimwe nzira dzekugadzira pombi, kugadzirwa kweDouble Submerged Arc Welded Pipe kunosanganisira kutanga kugadzira marata esimbi kuita cylindrical shapes.Micheto yeplate yakakungurutswa inoumbwa kuitira kuti V-shaped grooves iumbwe mukati uye kunze kwekunze panzvimbo ye seam.Iyo musono wepombi inozobatanidzwa nekamwe pass yearc welder mukati nekunze kwekunze (saka yakanyura kaviri).Iyo welding arc inonyudzwa pasi pe flux.
Kubatsira kweiyi nzira ndeyokuti welds inopinda 100% yemadziro epombi uye inoburitsa chisungo chakasimba chepombi zvinhu.
Seamless Pipe
Pombi isina musono yakagadzirwa kubvira kuma1800.Nepo maitiro akashanduka, zvimwe zvinhu zvakaramba zvakafanana.Seamless pombi inogadzirwa nekubaya inopisa denderedzwa simbi billet ine mandrel.Simbi yakagochwa inopfuura yakakungurutswa uye yakatambanudzwa kuti iwane hurefu hwaidiwa uye dhayamita.Kubatsira kukuru kwepombi isina musono ndiko kubviswa kwekuremara kwakabatana nemusono;zvisinei, mutengo wekugadzira wakakura.
Pombi yekutanga isina musono yaibatwa nekuremara kunokonzerwa nekusachena musimbi.Sezvo unyanzvi hwokugadzira simbi hwakavandudzwa, urema uhwu hwakaderedzwa, asi husati hwabviswa chose chose.Kunyange zvichiita sekuti pombi isina musono ingave iri nani kuumbwa, musono-welded pombi, kugona kuvandudza hunhu hunodiwa mupombi kunogumira.Nechikonzero ichi, pombi isina musono iripo parizvino mumagiredhi akaderera uye ukobvu hwemadziro pane welded pombi.
Jindalai Steel Group ine hunyanzvi mukugadzira yepamusoro-tech ERW (Electric Resistance Welded) uye SSAW (Spiral Submerged Arc welded) pombi.Kambani yedu yakakwira φ610 mm yakakwira-frequency yakatwasuka musono kuramba welding muchina, uye φ3048mm spiral yakanyura arc welded muchina.Zvakare, kunze kwemafekitari eERW neSSAW, tine mamwe mafekitori matatu anodyidzana ekugadzira LSAW neSMLS muChina.
Kana kutenga pombi kuri mune ramangwana rako riri pedyo, kumbira mutengo.Isu tinokupa iyo inokuwanira iwe chaizvo zvigadzirwa zvaunoda nekukurumidza.Tumira kubvunza kwako uye isu tichafara kukubvunza iwe nehunyanzvi.
Isu Jindalai Steel Group vagadziri, vanotengesera kunze, vane stock uye mutengesi wemhando yeSimbi Pipe.Tine mutengi kubva kuThane, Mexico, Turkey, Pakistan, Oman, Israel, Egypt, Arab, Vietnam, Myanmar.Tumira kubvunza kwako uye isu tichafara kukubvunza iwe nehunyanzvi.
