Imibhobho yentsimbi iza ngeendlela ezininzi kunye nobukhulu.Umbhobho ongenamthungo yindlela engabonakaliyo, eyenziwe nge-billet yensimbi enemingxuma.Xa kuziwa kwimibhobho yensimbi edibeneyo, kukho iindlela ezintathu: i-ERW, i-LSAW kunye ne-SSAW.
Imibhobho ye-ERW yenziwe ngamacwecwe entsimbi adityanisiweyo.Umbhobho we-LSAW wenziwa ngepleyiti yentsimbi edityanisiweyo ye-arc yobude.Umbhobho we-SSAW wenziwa ngepleyiti yentsimbi edityanisiweyo ye-arc.
Makhe sihlolisise ngakumbi uhlobo ngalunye lombhobho, thelekisa ukungafani kwabo, kunye nendlela yokusebenzisa inkcazo echanekileyo ukucwangcisa.
ityhubhu yentsimbi engenamthungo
I-tube engenamthungo yenziwe nge-billet yensimbi engenasici, eshushu kwaye ifakwe kwi-perforated ukuze yenze icandelo elijikelezayo elingenanto.Ngenxa yokuba umbhobho ongenamthungo awunayo indawo ye-welding, uthathwa njengonamandla kunombhobho odityanisiweyo kwaye awufuni ukubola, ukukhukuliseka kunye nokungaphumeleli ngokubanzi.
Nangona kunjalo, ixabiso ngetoni nganye yombhobho ongenamthungo yi-25-40% ephezulu kunombhobho we-ERW.Iisayizi zemibhobho yentsimbi engenamthungo ukusuka kwi-1/8 intshi ukuya kuma-36 intshi.
Umbhobho we-Resistance welding (ERW).
I-ERW (i-resistance welding) ipayipi yensimbi yenziwa ngokuqengqeleka kwentsimbi kumbhobho kunye nokudibanisa iziphelo ezimbini kunye nee-electrode ezimbini zobhedu.Ezi electrode ziyi-disc kwaye zijikeleza njengoko izinto zidlula phakathi kwazo.Oku kuvumela i-electrode ukuba igcine uqhagamshelwano oluqhubekayo kunye nezinto eziphathekayo ixesha elide lokudibanisa ngokuqhubekayo.Inkqubela phambili yeteknoloji ye-welding iyaqhubeka nokuphucula le nkqubo.
Umbhobho we-ERW uthatha indawo yoqoqosho nesebenzayo yombhobho wentsimbi engenamthungo, ehlala ixesha elide kunombhobho we-SAW.Xa kuthelekiswa nenkqubo ye-solvent esetyenziswe kumbhobho we-arc welded we-submerged, iziphene nazo azinakwenzeka ukuba zenzeke, kwaye iziphene ze-weld ezichanekileyo zingabonwa ngokulula ngokubonakaliswa kwe-ultrasonic okanye umbono.
Ububanzi bombhobho we-ERW busuka kwi-intshi (15 mm) ukuya kuma-intshi angama-24 (21.34 mm).
Umbhobho odityanisiweyo we-arc
I-LSAW (i-welding ye-seam ethe tye) kunye ne-SSAW (i-spiral seam welding) zizinto ezahlukileyo zombhobho odityanisiweyo we-arc.Inkqubo ye-arc welding ephantsi kwamanzi ivelisa ukuxinana okuphezulu kwangoku ukukhusela ukutshatyalaliswa kobushushu okukhawulezayo kwe-flux layer kunye nokugxila kwindawo ye-welding.
Umahluko ophambili phakathi kwe-LSAW kunye ne-SSAW imibhobho yindlela ye-weld, eya kuchaphazela amandla oxinzelelo kunye nokulula kokuvelisa.I-LSAW isetyenziselwa ukusetyenziswa kwe-voltage ephakathi ukuya kwi-high-voltage applications, kwaye i-SSAW isetyenziselwa ukusetyenziswa kwe-voltage ephantsi.Imibhobho ye-LSAW ibiza kakhulu kunemibhobho ye-SSAW.
Umbhobho odityanisiweyo we-arc wobude
Umbhobho we-LSAW wenziwa ngokwenza umngundo wensimbi we-coil eshushu kwi-cylinder kunye nokudibanisa iziphelo ezimbini kunye ne-welding linear.Oku kudala umbhobho odityaniswe ngobude.Le mibhobho isetyenziselwa ikakhulu imibhobho yothumelo olude lweoyile, igesi yendalo, amalahle elulwelo, iihydrocarbons, njl.
Kukho iindidi ezimbini zemibhobho ye-LSAW: i-single longitudinal seam kunye ne-double seam (DSAW).Umbhobho wentsimbi we-LSAW ukhuphisana nombhobho wentsimbi ongenamthungo kunye nombhobho wentsimbi we-intshi we-16 ukuya kuma-intshi we-ERW.Kwishishini leoli kunye negesi yendalo, imibhobho ye-API 5L LSAW enobubanzi obukhulu isetyenziselwa ukuthuthwa okude kunye nokuhamba kakuhle kwee-hydrocarbons.
Ubukhulu bombhobho woMTHETHO buhlala buphakathi kwe-intshi ze-16 kunye ne-60 intshi (406 mm kunye ne-1500 mm).
Umthungo - iintsalela eziqhumayo zemfazwe - ukuwelda kwe-arc entywilayo emide - ukuwelda kwe-arc entywilayo - umbhobho - ukuwelda kwe-arc entywilayo
umbhobho we-SSAW
Umbhobho wentsimbi we-SSAW wenziwe ngokuqengqeleka kunye nokuwelda umcu wentsimbi kwi-spiral okanye kwi-spiral direction ukwenza i-weld ibe yi-spiral.Inkqubo ye-spiral welding yenza kube lula ukwenza iimveliso ezinobubanzi obukhulu.Imibhobho yentsimbi eSpiral isetyenziswa ikakhulu kuxinzelelo oluphantsi lokuhambisa ulwelo, olufana nemibhobho kumaqonga angaphesheya kolwandle, izityalo zepetrochemical okanye iindawo zeenqanawa, kunye nezakhiwo zasekuhlaleni kunye nemfumba.
Uluhlu lwedayamitha yombhobho we-SSAW luqhelekile zii-intshi ezingama-20 ukuya kwii-intshi ezingama-100 (406 mm ukuya kuma-25040 mm).
Indlela yoku-odola iipayipi zentsimbi kwiprojekthi yakho
Xa uyala iipayipi zensimbi, kukho imilinganiselo emibini ebalulekileyo: ubungakanani bombhobho obizwa ngokuba yi-NPS kunye nobukhulu bodonga (ishedyuli).Kwimibhobho engaphantsi kwama-intshi angama-4, ubude bombhobho bungaba yi-random eyodwa (SRL) i-5-7 yeemitha, okanye kwimibhobho engaphezu kwe-intshi ezi-4, ubude bombhobho bungaba kabini ngokungahleliwe (DRL) 11-13 iimitha.Ubude obuqhelekileyo buyafumaneka kwimibhobho emide.Iziphelo zombhobho zinokuba yi-bevel (ibe), indiza (pe), intambo (THD) intambo kunye nokudibanisa (T&C) okanye igroove.
