Iipayipi zentsimbi ziza ngeendlela ezahlukeneyo nangobukhulu obahlukeneyo. Iipayipi ezingenamthungo lukhetho olungadityanisiweyo, olwenziwe ngentsimbi enomngxuma. Xa kufikwa kwiipayipi zentsimbi ezidityanisiweyo, kukho iindlela ezintathu: i-ERW, i-LSAW kunye ne-SSAW.
Imibhobho ye-ERW yenziwe ngeepleyiti zentsimbi ezidityanisiweyo ezichaseneyo. Umbhobho we-LSAW wenziwe ngepleyiti yentsimbi edityanisiweyo ende engaphantsi komhlaba. Umbhobho we-SSAW wenziwe ngepleyiti yentsimbi edityanisiweyo engaphantsi komhlaba ejikelezileyo ejikelezileyo.
Masiqwalasele ngokusondeleyo uhlobo ngalunye lombhobho, sithelekise umahluko phakathi kwawo, nendlela yokusebenzisa inkcazo echanekileyo ukuze ilandelwe.
Ityhubhu yentsimbi engenamthungo
Ityhubhu engenamthungo yenziwe ngentsimbi engenasici, efudunyezwayo kwaye igqobhozeke ukuze yenze icandelo elijikelezayo elingenanto. Ngenxa yokuba ipayipi engenamthungo ayinandawo yokuwelda, ithathwa njengeyomeleleyo kunepayipi eweldayo kwaye ayichaphazeleki lula kukubola, ukukhukuliseka kunye nokungasebenzi kakuhle ngokubanzi.
Nangona kunjalo, ixabiso ngetoni yombhobho ongenamthungo liphezulu ngama-25-40% kunelo lombhobho we-ERW. Ubungakanani bombhobho wentsimbi engenamthungo buqala kwi-1/8 intshi ukuya kwi-36 intshi.
Umbhobho wokuwelda ochaseneyo (ERW)
Umbhobho wentsimbi we-ERW (ukuwelda kokumelana) wenziwa ngokuqengqa intsimbi ibe yipayipi kwaye udibanise iziphelo ezimbini ngee-electrode ezimbini zobhedu. Ezi electrode zimile okwediski kwaye zijikeleza njengoko izinto zidlula phakathi kwazo. Oku kuvumela i-electrode ukuba igcine unxibelelwano oluqhubekayo nezinto ixesha elide lokuwelda okuqhubekayo. Inkqubela phambili yetekhnoloji yokuwelda iyaqhubeka nokuphucula le nkqubo.
Umbhobho we-ERW uyindlela engabizi kakhulu nesebenzayo yokuthatha indawo yombhobho wentsimbi engenamthungo, ohlala ixesha elide kunembhobho ye-SAW. Xa kuthelekiswa nenkqubo yesinyibilikisi esetyenziswa kumbhobho we-arc welded ongaphantsi komhlaba, iziphene nazo akunakwenzeka ukuba zenzeke, kwaye iziphene ze-weld ezithe tye zinokubonwa lula ngokukhanya kwe-ultrasonic okanye umbono.
Ububanzi bombhobho we-ERW buqala kwii-intshi (15 mm) ukuya kwii-intshi ezingama-24 (21.34 mm).
Umbhobho odibeneyo we-arc ofakwe emanzini
I-LSAW (i-straight seam welding) kunye ne-SSAW (i-spiral seam welding) ziintlobo ezahlukeneyo zepayipi edibeneyo ye-arc. Inkqubo yokudibanisa i-arc engaphantsi komhlaba ivelisa uxinano olukhulu lwamandla ombane ukuthintela ukutshatyalaliswa kobushushu ngokukhawuleza komaleko we-flux kunye nokugxila kwindawo yokudibanisa.
Umahluko ophambili phakathi kwemibhobho ye-LSAW kunye ne-SSAW yindlela ebekwe ngayo i-weld, eya kuchaphazela amandla okuthwala uxinzelelo kunye nokulula kokwenziwa kwayo. I-LSAW isetyenziselwa ukusetyenziswa kwe-voltage ephakathi ukuya kwi-voltage ephezulu, kwaye i-SSAW isetyenziselwa ukusetyenziswa kwe-voltage ephantsi. Imibhobho ye-LSAW ibiza kakhulu kunemibhobho ye-SSAW.
Umbhobho we-arc welded welded welded welded arc engaphantsi komhlaba
Umbhobho we-LSAW wenziwa ngokwenza i-hot rolled steel mold ibe yi-cylinder kwaye udibanise iziphelo ezibini kunye nge-linear welding. Oku kudala umbhobho odibeneyo ojikelezayo. Le mibhobho isetyenziselwa ikakhulu imibhobho yokuhambisa ioyile, igesi yendalo, amalahle angamanzi, ii-hydrocarbon, njl.njl.
Kukho iintlobo ezimbini zeepayipi ze-LSAW: umthungo omnye othe tyaba kunye nomthungo ophindwe kabini (i-DSAW). Umthungo wentsimbi we-LSAW ukhuphisana nomthungo wentsimbi ongenamthungo kunye nomthungo wentsimbi we-ERW oyi-intshi ezili-16 ukuya kwezingama-24. Kwishishini leoyile negesi yendalo, iipayipi ze-LSAW ze-API 5L ezinkulu zisetyenziselwa ukuthutha ii-hydrocarbons umgama omde kunye nokusebenza kakuhle.
Ububanzi bombhobho we-LAW buhlala buphakathi kwe-16 intshi kunye ne-60 intshi (406 mm kunye ne-1500 mm).
Akukho mthungo - iintsalela eziqhumayo zemfazwe - ukuwelda kwe-arc engaphantsi komhlaba okude - ukuwelda kwe-arc engaphantsi komhlaba okujikelezayo - umbhobho - ukuwelda kwe-arc engaphantsi komhlaba okujikelezayo
Umbhobho we-SSAW
Umbhobho wentsimbi we-SSAW wenziwa ngokuqengqa nokuwelda umcu wentsimbi kwicala elijikelezayo okanye elijikelezayo ukuze kwenziwe i-weld ibe yi-spiral. Inkqubo ye-spiral welding yenza kube nokwenzeka ukuvelisa iimveliso ezinobukhulu obukhulu. Imibhobho yentsimbi ejikelezayo isetyenziselwa kakhulu ukuhanjiswa kolwelo oluphantsi koxinzelelo, njengemibhobho kwiindawo ezikude nolwandle, izityalo ze-petrochemical okanye iinqanawa, kunye nezakhiwo zoluntu kunye nokufaka inqwaba.
Uluhlu lobubanzi bepayipi ye-SSAW ngokubanzi luyi-20 intshi ukuya kwi-100 intshi (406 mm ukuya kwi-25040 mm).
Indlela yoku-odola imibhobho yentsimbi kwiprojekthi yakho
Xa u-odola imibhobho yentsimbi, kukho imilinganiselo emibini ephambili: ubungakanani bombhobho oqhelekileyo (i-NPS) kunye nobukhulu bodonga (ishedyuli). Kwimibhobho engaphantsi kwe-intshi ezi-4, ubude bombhobho bunokuba yi-single random (SRL) yeemitha ezi-5-7, okanye kwimibhobho engaphezulu kwe-intshi ezi-4, ubude bombhobho bunokuba yi-double random (DRL) yeemitha ezili-11-13. Ubude obuqhelekileyo buyafumaneka kwimibhobho emide. Iziphelo zemibhobho zinokuba yi-bevel (be), i-plane (pe), i-thread (THD) kunye ne-coupling (T&C) okanye i-groove.
