Iipayipi zentsimbi zingahlulwa ngokwenkqubo yokuqengqeleka, nokuba kukho imithungo okanye akunjalo, kunye nemilo yecandelo. Ngokwendlela yokuqengqeleka kwenkqubo, iipayipi zentsimbi zingahlulwa ngokwemithungo yentsimbi eqengqeleka eshushu kunye neepayipi zentsimbi eziqengqeleka ebandayo; ngokwendlela yokuba iipayipi zentsimbi zinemithungo na, iipayipi zentsimbi zahlulwe zibe yimithungo yentsimbi engenamthungo kunye neepayipi zentsimbi ezihlanganisiweyo, phakathi kwazo apho iipayipi zentsimbi ezihlanganisiweyo ezisetyenziswa rhoqo zingahlulwa zibe yimithungo ehlanganisiweyo ephindaphindekayo ngokwendlela yokugquma. , umthungo othe tye ogqume i-arc egqume i-arc, umthungo ogqume i-arc egqume i-spiral, njl.
Ubukhulu bodonga lombhobho wentsimbi engenamthungo bubukhulu kwaye ubukhulu bobubanzi buncinci. Nangona kunjalo, ububanzi bombhobho buncinci, ukusetyenziswa kwawo nako kuncinci, kwaye iindleko zokuvelisa, ingakumbi iindleko zokuvelisa imibhobho yentsimbi engenamthungo enobukhulu obukhulu, ziphezulu.
Umbhobho odibeneyo ophindaphindwayo unemilo emihle yetyhubhu kunye nobukhulu bodonga obufanayo. Iibharrs zangaphakathi nezangaphandle eziveliswa kukudityaniswa ziyagudiswa zizixhobo ezifanelekileyo, kwaye umgangatho womthungo wokudityaniswa ulawulwa ngokungqongqo ngovavanyo olungenakonakala olukwi-intanethi. Umgangatho wokwenziwa kwezinto ngokuzenzekelayo uphezulu kwaye iindleko zemveliso ziphantsi. Nangona kunjalo, ubukhulu bodonga buncinci kwaye ububanzi bombhobho buncinci, nto leyo efanelekileyo ngokukodwa ekwenzeni izakhiwo ze-truss yombhobho kwizakhiwo zentsimbi.
Umbhobho othe tye ofakwe i-arc welded usebenzisa inkqubo yokuwelda i-arc welding efakwe i-arc welding enamacala amabini, efakwe i-weld phantsi kweemeko ezingashukumiyo, umgangatho wokuwelda uphezulu, i-weld imfutshane, kwaye amathuba okuba neziphene mancinci. Umbhobho wentsimbi wandiswa kulo lonke ubude, imilo yombhobho ilungile, ubungakanani buchanekile, uluhlu lobukhulu bodonga lombhobho wentsimbi kunye nobubanzi bombhobho bubanzi, inqanaba lokuzenzekelayo liphezulu, kwaye iindleko zemveliso ziphantsi xa kuthelekiswa nombhobho wentsimbi ongenamthungo, ofanelekileyo kwizakhiwo, iibhulorho, amadama, kunye namaqonga aselunxwemeni. Iikholamu ezinesakhiwo sentsimbi esilinganayo, izakhiwo zesakhiwo esine-super-span kunye nezakhiwo ze-pole tower mast ezifuna ukumelana nomoya kunye nokumelana nenyikima.
Umthungo wokuwelda wepayipi efakwe i-spiral submerged arc welded usasazwa nge-spiral, kwaye umthungo wokuwelda mde. Ingakumbi xa kudityaniswa phantsi kweemeko ezitshintshayo, umthungo wokuwelda ushiya indawo yokwenza ngaphambi kokuba uphole, kwaye kulula kakhulu ukuvelisa imifantu eshushu yokuwelda. Ke ngoko, iipropati zayo zokugoba, zokutyhafa, zokucinezela kunye nezokujikeleza ziphantsi kakhulu kunezo zemibhobho ye-LSAW, kwaye kwangaxeshanye, ngenxa yokuthintelwa kwendawo yokuwelda, ii-welds ezimile okwesaddle kunye nezimile okwe-fish-ridge eziveliswayo zichaphazela imbonakalo. Ukongeza, ngexesha lenkqubo yokwakha, umgca odibanisayo weld kwi-node yombhobho womzali ofakwe i-spiral welded wahlula umthungo ojikelezayo, nto leyo ebangela uxinzelelo olukhulu lokuwelda, ngaloo ndlela kunciphisa kakhulu ukusebenza kokhuseleko lwecandelo. Ke ngoko, uvavanyo olungonakalisiyo lwepayipi efakwe i-spiral weld kufuneka luqiniswe. Qinisekisa umgangatho wokuwelda, kungenjalo umbhobho ofakwe i-spiral submerged arc welded akufuneki usetyenziswe kwiziganeko ezibalulekileyo zesakhiwo sentsimbi.
