Ukubaluleka kokuphuhlisa umthungo we-longitudinal umbhobho odityanisiweyo we-arc

Okwangoku, imibhobho isetyenziselwa kakhulu ukuthutha ioli kunye negesi. Imibhobho yentsimbi yombhobho esetyenziswa kwimibhobho emide kakhulu ibandakanyaimibhobho yentsimbi edityanisiweyo ye-arckunye nemibhobho yentsimbi edityanisiweyo enamacala amabini e-arc edityanisiweyo. Ngenxa yokuba i-spiral submerged arc welded pipe yenziwe ngentsimbi ye-strip kunye nobukhulu bodonga lwayo lulinganiselwe, ukuphuculwa komgangatho wentsimbi kuthintelwe kunyango lobushushu bezinto eziphathekayo. Ukongeza, kukho iziphene ezingenakugqithiswa ze-spiral submerged arc welded pipe, ezifana ne-weld ende, uxinzelelo olukhulu olushiyekileyo kunye nokuthembeka okubi kwe-weld. Ngeemfuno ezikhulayo zemibhobho yentsimbi yokuhanjiswa kwe-oyile kunye negesi, ayisasetyenziswa kwiindawo ezinabantu abaninzi kunye neendawo ezineemfuno eziphezulu zokuthembeka, kunyeimibhobho edityanisiweyo yobubanzi obukhulungokuthe ngcembe batshintsha imibhobho e-spiral welding.

Kutshanje, iTshayina ikhawulezisa uphuhliso lweoyile kunye negesi kuLwandle lwaseTshayina lwaseMpuma. Ngophuhliso lokusetyenziswa kwe-oyile ukuya enzulwini yolwandle, umbhobho obekwe phezu kolwandle uchatshazelwa yimikhosi edibeneyo yoxinzelelo, amandla empembelelo kunye namandla okugoba, kwaye isabonakala isenzeko sokucaba, elikhonkco elibuthathaka le-spiral welded. umbhobho. Ukuze kuphuculwe umthamo wothutho lwemibhobho kunye nokuqinisekisa umbhobho wenkwili oza kuphuhla ukuya eludongeni olungqindilili, umbhobho wenkwili uthatha ubukhulu becala umbhobho odityanisiweyo othe ngqo. Ke ngoko, xa kuthelekiswa nombhobho odityanisiweyo ovunguzayo, umbhobho odityanisiweyo othe tye unokuchaneka okuphezulu kunye nokulungisa ukuwelda lula, ngoko ke kulo mba, umbhobho odityanisiweyo othe tye ukwalukhetho lokuqala.

Oomatshini, ulwakhiwo, ishishini lemichiza kunye namanye amashishini afuna imibhobho edityanisiweyo ethe ngqo. Okwangoku, umngxuma ongaphakathi wesihlalo sevalvu senziwe ngoomatshini emva kokwenziwa kumashishini oomatshini, odla abasebenzi, ochitha ixesha kunye nezinto eziphathekayo. Ukuba kusetyenziswa umbhobho odityanisiweyo othe nkqo odityanisiweyo, uya kuba noqoqosho ngakumbi. Ukongezelela, ngenxa yeemfuno zeempawu zemishini ye-anti-flattening, imibhobho edibeneyo edibeneyo isetyenziselwa ukwakha imibhobho; Umbhobho odityanisiweyo othe ngqo kulindeleke ukuba usetyenziselwe imibhobho yekhemikhali.
