Mapaipi esimbi anouya mumhando dzakasiyana-siyana uye saizi dzakasiyana-siyana. Mapaipi asina musono isarudzo isina kusungirirwa, yakagadzirwa nesimbi yakavharika. Kana zvasvika kumapaipi esimbi akasungirirwa, pane sarudzo nhatu: ERW, LSAW neSSAW.
Mapaipi eERW akagadzirwa nemaplate esimbi akasungirirwa ne resistance welded. Mapaipi eLSAW akagadzirwa neplate yesimbi yakasungirirwa ne arc yakasungirirwa kwenguva refu. Mapaipi eSSAW akagadzirwa neplate yesimbi yakasungirirwa ne arc yakasungirirwa ne spiral.
Ngatinyatsoongorora mhando yega yega yepombi, enzanisai kusiyana kwayo, uye mashandisirwo anoitwa tsananguro chaiyo pakurongeka kwayo.
Chubhu yesimbi isina musono
Chubhu iyi isina musono yakagadzirwa nesimbi isina ngura, iyo inodziiswa uye inoboorwa kuti iite chikamu chakatenderera chine gomba. Nekuti pombi isina musono haina nzvimbo yekuunganidzira, inoonekwa seyakasimba kupfuura pombi yakaunganidzirwa uye isingakuvadzi ngura, inokurwa uye inokundikana zvakanyanya.
Zvisinei, mutengo wepaipi isina musono patani imwe neimwe wakakwira ne25-40% kupfuura wepaipi yeERW. Saizi dzepaipi dzesimbi dzisina musono dzinotangira pa 1/8 inch kusvika 36 inch.
Pombi yekudzivirira welding (ERW)
Pombi yesimbi yeERW (resistance welding) inoumbwa nekukanda simbi mupombi uye kubatanidza magumo maviri nemaelectrode maviri emhangura. Maelectrode aya akaita sedhisiki uye anotenderera sezvo chinhu chinopfuura pakati pawo. Izvi zvinobvumira electrode kuti irambe iine hukama nechinhu kwenguva yakareba ichibatanidza nguva dzose. Kufambira mberi kwetekinoroji yewelding kuri kuramba kuchivandudza maitiro aya.
Pombi yeERW inotsiva pombi yesimbi isina musono, iyo inogara kwenguva refu kupfuura pombi yeSAW. Kana tichienzanisa nemaitiro ekunyungudutsa anoshandiswa mupombi yakasungirirwa muarc, zvikanganiso hazviwanzoitika, uye zvikanganiso zve weld yakatwasuka zvinogona kuonekwa zviri nyore ne ultrasonic reflection kana kuona.
Dhayamita yepombi yeERW inotangira pamainji (15 mm) kusvika pamainji makumi maviri nemana (21.34 mm).
Pombi yakanyudzwa yesimbi yakasungirirwa
LSAW (straight seam welding) uye SSAW (spiral seam welding) imhando dzakasiyana dzemapaipi akasungirirwa pasi pemvura. Maitiro ekubatanidza pasi pemvura akasungirirwa pasi anogadzira huwandu hwakawanda hwemagetsi kudzivirira kupisa nekukurumidza kupera kwe flux layer uye kuisa pfungwa munzvimbo yekushongedza.
Musiyano mukuru uripo pakati pemapaipi eLSAW neSSAW ndekwakanangana ne weld, iyo inokanganisa kugona kwekutakura pressure uye nyore kwekugadzira. LSAW inoshandiswa pakushandisa magetsi ari pakati nepakati kusvika pamagetsi ane simba guru, uye SSAW inoshandiswa pakushandisa magetsi ari pasi. Mapaipi eLSAW anodhura kupfuura mapaipi eSSAW.
Pombi yakasungirirwa yearc yakanyudzwa kwenguva refu
Pombi yeLSAW inogadzirwa nekugadzira mold yesimbi inopfurwa nekupisa kuita silinda uye kubatanidza mativi maviri pamwe chete nekubatanidza netambo. Izvi zvinogadzira pombi yakapfurwa kwenguva refu. Mapaipi aya anonyanya kushandiswa pakufambisa mafuta, gasi rechisikigo, marasha emvura, mahydrocarbon, nezvimwewo.
Kune mhando mbiri dzemapaipi eLSAW: musono mumwe chete wenguva refu nemusono wekaviri (DSAW). Pombi yesimbi yeLSAW inokwikwidzana nepaipi yesimbi isina musono uye pombi yesimbi yeERW ine 16 kusvika 24 inch. Muindasitiri yemafuta negasi rechisikigo, mapaipi eLSAW ane dhayamita hombe eAPI 5L anoshandiswa kutakura mahydrocarbon kure uye zvinobudirira.
Dhayamita yepombi yeLAW inowanzova pakati pemasendimita makumi mana nematanhatu nemazana matanhatu (406 mm ne1500 mm).
Pasina musono - zvisaririra zvehondo zvinoputika - kusanganisa arc yakadzikwa kwenguva refu - kusanganisa arc yakadzikwa nemhepo inotenderera - mapaipi - kusanganisa arc yakadzikwa nemhepo inotenderera
Pombi yeSSAW
Pombi yesimbi yeSSAW inoumbwa nekumonera nekubatanidza simbi nenzira inotenderera kana inotenderera kuti iite kuti simbi ipinde mudenderedzwa. Maitiro ekubatanidza simbi anotenderera anoita kuti zvikwanisike kugadzira zvigadzirwa zvine dhayamita hombe. Mapombi esimbi anotenderera anonyanya kushandiswa pakutumira mvura ine simba shoma, senge mapaipi ari mumahombekombe egungwa, mafekitori epetrochemical kana nzvimbo dzezvikepe, pamwe nezvivakwa zvehurumende nekuisa zvinhu mudura.
Upamhi hwepombi dzeSSAW hunowanzova masendimita makumi maviri kusvika zana (406 mm kusvika 25040 mm).
Maitiro ekuraira mapaipi esimbi epurojekiti yako
Pakuodha mapaipi esimbi, pane zvinhu zviviri zvakakosha: saizi yepombi (NPS) uye ukobvu hwemadziro (chirongwa). Kune mapaipi ari pasi pemasendimita mana, kureba kwepombi kunogona kuva kamwe chete (SRL) mamita 5-7, kana kuti pamapaipi anopfuura masendimita mana, kureba kwepombi kunogona kuva kaviri kamwe chete (DRL) mamita 11-13. Kureba kwakagadzirwa nemaoko kunowanikwa kune mapaipi marefu. Migumo yemapaipi inogona kuva bevel (be), plane (pe), thread (THD) thread uye coupling (T&C) kana groove.
