Kwiindlela yesi "ERW" (Electric Resistance Welding), isithuthi sasendaweni sihlola phakathi komkhulu wecoils wesithuthi esilandelwe ngokuhlula emanzini. Ukungenisa amaxesha angaphambili, amacoli amadluliswa phakathi komkhulu we-rollers kunye nokugcina ngokukhululeka ngokusemva kwabo ukuba babecinzane amaxesha amahhulu. Izicatulo ezimbini ezilandelwe ngokuhlula, zibhalisiwe ngokumoya wesikhatsi esebenza ukuyigcina ukuba zisetyenziswa.
I-ERW pipe yintlango enguquleyo kakhulu lokugcina ukuthi zisebenzisi ngazo manje ngenxa yokuba kukho kuhluke kakhulu ngaphandle kokuthi iindlela ezinnye zesi Steel Pipe zizokulula. Ukuthi i-ERW Pipe iyasebenza, uzogcinwa nokuboniswa ngasinye. Ngokwesentile, i-ERW Pipe inikwe imibono eziyisihlanu njengoba iyakuhlala ekupheleni kwezilondolozi lwezintshona namanye amagama okusekisweni. Amabhebhu angaba abanini abasebenzisa i-ERW Pipe ngokukhanya, ngoba kuhluke kakhulu ukuthi akuyifundekwane kwindawo yakho yokuthenga kunye nezinto ezinikezayo ezinomsindo. Njengoko uhlamvu olunomasiko, uyahlala ukuthi abasebenzela babaluleka ngokushesha ngemva kokuthi zingezantsi.
I-ERW pipe ineziseko ezininzi ngemibuzo yeprojekthi. Isigodlo esikhulu sifuneka ngenxa yokuba kuhluke kakhulu ukugcina lokhu ngokubanzi kunye nezinye izindlela zezipayipi. Ukukhupha okuhluke kahle kube ngokulandelana nokuthi isithombe sikwazi ukusuka imali engaphezulu eminingi wezi zityala. Ngokuhlola, ngoba i-ERW pipe iyavakasha lokhu kungcono ukusetshenziswa ngamaziko amaningi nokuphela emakhisheni. Naye inguqulo kakhulu lokusebenza, lokuna umsebenzisi wabesetshenziswa ukuyenza lokwethembeka ngokwabo.
Kufanele usuke usondezele ukuba kukhonjwa kokusetshenziswa kwe-ERW pipe. Isigodlo esikhulu sengxoxo elikhulu lube ngokuba ayiqinile ngaphandle kwesinye. Lokho kungcono ukuthi i-ERW pipe angayidalwa ngokukhulu kumthetho we-160 noma epheleleyo kunye nokuthi izicwangciso ezidinga lokhu kuhluke kakhulu. Ngokuhlola, i-ERW pipe ingenisa ukudabula nokushintsha ngokulandelayo. Ukuthi akwenzekanga kuhambisana nokuvakasha lokhu kuzoba kuhlola amanqaku nokuncedisi phakathi kwesikhashana.
Yintoni ngaphandle kwezinye izigaba zonke ezinethemba ngenxa yokuba kunye nomnyama okanye amanqaku apho akukho indawo eziphakamisekileyo emidini, uza wenzele ngokulandelayo. Ngaphezulu, ASTM A53 yintlizyo enguqukumbeni ekugcinwayo kakhulu ngalokhu olungena kwezi zintlobo ezidingekayo eziningi. Indawo eyahlukene enguqukumbeni ekugcinwayo kulandelwa kwezi boibhi ngokubanzi kwenqanawa nokuphumeleyo kwesithathu sokugcina ukuthi kube noma umthombo wokuqala wesithathu lokusebenza.
Zingabafundi abaningi ngestandardi A333 (isixhobo esiqhelekileyo) kunye ne-5L API, Porch wayesetshenziswa ngokubheka lokuhlola iindlela zokugcina amagwayide we-oil kunye ne-gas. Ukusetha ingxelo yesithathu elandelayo lesi ERW pipe liphatha, ngoba uzoba ukuba uhlanganisa isithathu sengxenye yokusebenza. Lokhu kuvumela ukuthi isithathu sigcine ngempumelelo, ngaphandle kokuthi kufuneka.
Ukuphepha nokuhlinza okujongene kwezinye zamaERW ngokwesikhathi kuvunyelwa xa ufuna ukusure ka ukuba umthetho wakho uyasembenza ngokukhululeka. Oku kungaba ngokushesha ukubhala amaxhobo okanye iholes ezinenzekayo ukucabanga ukuba azikopise inani lamahora. Ngokushesha kwamava ukubheka kwezinye izinto, kufuneka amaphrofeshenali aphumelele ngenqanawe yezinto ezifanelekayo ezizenzakalo.
Shandong Changshengda Steel Co Ltd iyindawo yezinto eziqhutywa kakhulu ezinikezela amaxwebhu wezilungiselelo, lokuhlukene ukuthi amaxwebhu akho anqume ukuphakamisa i-hot rolling, cold drawing, cold rolling, coating, galvanizing noma ukubheka uphawu. Lendawo luyindlela le-erw pipe ngokushintsha umphawu ku-90001. Ukusetyenziswa kwesikwekwe sikhona ngemva kokuthi umnini wokuqala wokuthi wonke amatonithi angaphandle kweemili ethunghi, ezifanekisayo nokuthi ingxenye yesilungiselelo esebenzekile kwaye inani lesigxaki seliphakamiselwa ngalokulandelana nomnyaka. Ndawo yakho ingavume ukuba yileyo indawo engayityelelako ukusebenzisa imibuzo yokugcina kanye neziphumo zokubheka uphawu kunye namaxesha amabini.
I-Shandong Changshengda Steel Co Ltd ifuneka kwi-Chinayini yomthwalo wemidlalo we-steel pipe okubanzi kunye nokuthi u-seamless. Ukusetyenziswa kwakhiwe ngokulandelana. Lelimi liyishumi naye lishumi elishumi elihlanu elibekwe ngo-2011 njenge-"National 863 Program Project Execution Unit". Leliqhosha lihlosi le-800 amaxesha apha, afunekayo amaxesha amashumi amabini otheqweni nezikhatsi ezintathu ezimfutshane. Ifaki lifuneka kumgca wesithathu erw pipe. Yintlizyo engaphandle yaseChinayini eyafuna ukusetshenziswa kokuba kukho ukufundiswa komdlalo owenziwayo, ukusebenzisa kanye nokugcina.
Uguqulelo lwe-erw pipe ulandelayo nguqukethelo elingene ngezintathu ezizenzakalelayo ezifunekayo ukusetyenziswa kwenye amagcinisi akhe. Umphathi wemisebenzi wesikhephe siphakamisela iziphumo zonke ezingazixhaswa, njengemibuzo yophutha, imibuzo yesithuthi noma iimiswe yocwangciso, ngalokusha olungayiphi lexiyelentini olubhaliweyo ngesicelo. Ngokuhlala kunye nezinto zakhe ezilandelwayo kanye nokuphucumana ekugqibeleni, sizothola amaxwebhu eziphumeleyo kwiinkxaso zokukhuthaza, futhi sizobuya amandla nokulandelela kwindawo yokufinyelela ukukhangelana nazo zonke izinkinga ezixinxolo, ukuze abafundi bangasenza ngaphandle kokufunda kunye nokuhlonishwa kunye nokuthi abaningi ukuthi azidinge ukuba bazingeniswe.
I-Shandong Changshengda Steel Co Ltd yi 12 mizuzu kakhulu ehlukene ngekhanda lokusebenzisa nokulayisha kunye nechaini elikhulu emihla ethunyelwe ngeminyaka engu-150 esiqheleni sasendaweni, okungakuvumela abasebenzi abuyelele amaxwebhu angaphandle komalayiso babo. Ngokugcina, ukufunda kakhulu lwezimo zomthetho wobendlululo nokulayishwa kwezwe eziningi zizofutha isenzo semanje lokulayisha, uzokubuyisela abasebenzi ngokupheleleyo lokulayishwa, baza kufika imigomo yesithunyiswa esibonakaleyo ngaphandle kokuba kuhlala ekhaya.
