Kugadzirwa kwemapombi esimbi kwakatanga kuma1800. Pakutanga, mapombi aigadzirwa nemaoko - nekudziisa, kukotama, kunamatira, uye kurovera mipendero pamwe chete. Maitiro ekutanga ekugadzira mapombi otomatiki akatangwa muna 1812 muEngland. Maitiro ekugadzira akaramba achivandudzwa kubvira panguva iyoyo. Dzimwe nzira dzakakurumbira dzekugadzira mapombi dzakatsanangurwa pazasi.
Kukwevera pamakumbo
Kushandiswa kwe lap welding kugadzira mapaipi kwakatangwa kutanga kwema1920. Kunyangwe nzira iyi isingachashandiswi, mamwe mapaipi akagadzirwa achishandisa lap welding achiri kushandiswa nanhasi.
Mukuita kwekubatanidza simbi, simbi yaipiswa muchoto yobva yapetwa kuita se cylinder. Mipendero yeplate yesimbi yaibva ya "scarf". Kushongedza scarf kunosanganisira kufukidza mupendero wemukati weplate yesimbi, uye mupendero wakatetepa wedivi rakapesana replate. Musono waizosvetwa uchishandisa bhora rekusveta, uye pombi inopisa yaipfuudzwa pakati pemaroller izvo zvakamanikidza musono kuti ugadzire chisungo.
Maweld anogadzirwa ne lap welding haana kuvimbika seaya akagadzirwa achishandisa nzira dzemazuva ano. American Society of Mechanical Engineers (ASME) yakagadzira equation yekuverenga kumanikidzwa kwepombi kunobvumirwa, zvichibva parudzi rwemaitiro ekugadzira. Equation iyi inosanganisira variable inozivikanwa se "joint factor", iyo inobva parudzi rweweld inoshandiswa kugadzira musono wepombi. Mapaipi asina musono ane joint factor ye1.0 Lap welded pombi ine joint factor ye0.6.
Kuramba Kwemagetsi Welded Pipe
Pombi yemagetsi inogadziriswa nesimbi inogadzirwa nesimbi inotonhora kuita chimiro che cylindrical. Mhepo inopfuudzwa pakati pemipendero miviri yesimbi kuti ipise simbi kusvika painomanikidzwa mipendero kuti iite chisungo pasina kushandisa welding filler material. Pakutanga nzira iyi yekugadzira yaishandisa low frequency AC current kupisa mipendero. Maitiro aya e low frequency akashandiswa kubva kuma1920 kusvika 1970. Muna 1970, maitiro e low frequency akatsiviwa ne high frequency ERW process iyo yakagadzira weld yemhando yepamusoro.
Nekufamba kwenguva, ma weld emapaipi eERW ane frequency yakaderera akaonekwa kuti anogona kukanganiswa nengura yemusono, kutsemuka kwehook, uye kubatana kusina kukwana kwemusono, saka ERW ine frequency yakaderera haichashandiswi kugadzira mapaipi. Maitiro e frequency yakakwirira achiri kushandiswa kugadzira mapaipi ekushandisa mukuvaka mapaipi matsva.
Pombi Yemagetsi Yakasungirirwa Yemagetsi
Pombi yemagetsi yakasungirirwa pamagetsi yakagadzirwa kutanga muna 1927. Kusungirirwa pamagetsi kwakaitwa nekugadzira simbi yakaita se cylindrical. Mipendero yacho yaipiswa kusvika yanyatsonyungudutswa, yozobatanidzwa kusvika simbi yakanyungudutswa yabuda mujoini ndokuita bead. Kufanana nepombi yeERW ine frequency yakaderera, mipendero yepombi yakasungirirwa pamagetsi inogona kukuvadzwa nengura uye kutsemuka kwehoko, asi zvishoma pane pombi yeERW. Rudzi urwu rwepombi runogonawo kukundikana nekuda kwenzvimbo dzakaoma musimbi yeplate. Nekuti ruzhinji rwepombi yakasungirirwa pamagetsi rwakagadzirwa nemugadziri mumwe chete, zvinofungidzirwa kuti nzvimbo dzakaoma idzi dzakaitika nekuda kwekudzima simbi netsaona panguva yekugadzira inoshandiswa nemugadziri iyeye. Kusungirirwa pamagetsi hakuchashandiswi kugadzira pombi.
Pombi Yakanyudzwa Kaviri Yakanyudzwa muArc Welded (DSAW)
Kufanana nedzimwe nzira dzekugadzira mapaipi, kugadzirwa kweDouble Submerged Arc Welded Pipe kunosanganisira kutanga kugadzira mapurati esimbi kuita maumbirwo e cylindrical. Mipendero yeplate yakamonerwa inoumbwa kuitira kuti migero yakaita seV iumbwe pamusoro pemukati nekunze panzvimbo yemusono. Musono wepaipi unozobatanidzwa nepasuru imwe chete ye arc welder pamusoro pemukati nekunze (saka inonyudzwa kaviri). Arc welding inonyudzwa pasi pemvura.
Chinhu chakanaka chekuita izvi ndechekuti ma weld anopinda ne100% yemadziro epombi uye anogadzira chisungo chakasimba kwazvo chepombi.
Pipe Isina Musono
Pombi isina musono yave ichigadzirwa kubvira kuma1800. Kunyange hazvo maitiro acho achinja, zvimwe zvinhu zvakaramba zvakadaro. Pombi isina musono inogadzirwa nekuboora simbi inopisa yakatenderera ne mandrel. Simbi ine maburi inomonerwa nekutatamurwa kuti isvike pakureba nedhayamita rinodiwa. Chinhu chikuru chepombi isina musono kubvisa zvikanganiso zvine chekuita nemusono; zvisinei, mutengo wekugadzira wakakura.
Pombi dzepakutanga dzisina musono dzaive nyore kukanganiswa nekusvibiswa kwesimbi. Sezvo nzira dzekugadzira simbi dzakavandudzika, zvikanganiso izvi zvakaderera, asi hazvina kubviswa zvachose. Kunyange zvazvo zvichiita sekuti pombi dzisina musono dzaizonyanya kunaka pane pombi dzakagadzirwa, dzakasungirirwa nemusono, kugona kuvandudza hunhu hunodiwa mupombi kwakaderera. Nekuda kweizvi, pombi dzisina musono dziripo pari zvino mumhando dzakaderera uye dzakakora kupfuura pombi dzakasungirirwa.
