Izinkinga zekhwalithi yobuso bepayipi lensimbi zibonakala ikakhulukazi endaweni ewugqinsi ye-oxide, ukuqhekeka kobuso, isikhumba kabusha, amaphampu asebenza ngomshini njalo njalo. Ngemva kokuphothulwa kwensimbi egoqwayo egoqwe ngensimbi ebandayo bese kubanda ukushisa noma ngemva kwalokho. yakha ukunamathela okuqinile futhi okuqinile, izinga lokushisa eliphezulu le-oxide.Akukhona nje kuphela ukuba khona kwensimbi ye-oxide kubheka izinga eliphansi, futhi kuthinta ukusetshenziswa kwensimbi, okungavunyelwe yizinga.Ama-oxide anjalo ane-sandblasted evamile kunzima ukuwakhipha, ukusebenzisa i-pickling noma indlela yokupholisha ngomshini ukusula.
Ukuqhekeka komhlaba kwenzeke kunsimbi egoqelwe ngokushisayo, i-carbon steel evamile kanye namashubhu ensimbi yengxubevange, ikakhulukazi ngenxa yenqubo yokupholisa ngokushesha ukushuba okukhulu okubangelwa ingcindezi eyinsalela ebangelwa nangemuva kwayo. Imifantu ayikona okokuqhekeka kwendawo (akukho ukuhlukumezeka), kodwa ngezici ezithile zokuqhekeka kwakhiwa kumphumela wokuzwela kwenotshi ezimeni eziningi zohlelo (ezifana nezinga lokushisa eliphezulu, izinga lokushisa eliphansi, ukugqwala kokugqwala kwengcindezi yemvelo.njll.) ngezinga elithile, ukuze kwehliswe ukuphila kwepayipi lensimbi.futhi ngisho kuholela ekuhlulekeni kwamapayipi.
Ngakho-ke, imboni yangaphambili yensimbi kufanele iqhekeke. Indawo yesikhumba esindayo ivamile kumashubhu ensimbi agoqeke noma adonswe ngokubanda, ikakhulukazi ngenxa ye-billet surface noma i-abrasive engadalanga lutho. Ukuba khona okukhulu kuzothinta ukubukeka kwensimbi yekhwalithi yesikhumba umthelela ekusetshenzisweni kwepayipi lensimbi kanye ne-crack.yize kungeyona ebucayi.kodwa kwezinye izindawo kusenomthelela othile.Kuthuthukiswe ngokuqiniswa kokuphathwa kokukhiqiza, ukuthuthukisa nokulawula ikhwalithi yekhwalithi ye-billet surface kanye ne-abrasive.I-Mechanical bruise iyingxenye yezinkinga zekhwalithi ezijwayelekile kakhulu, ezikhiqizwa kakhulu ekukhiqizeni, ekuphatheni nasekuthuthweni.Insimbi izokwakha ukulimala ekunqanyulweni kwesakhiwo, ukusetshenziswa kuwumthombo wokugxilisa ingqondo yengcindezi, kodwa futhi kukhiqiza ukuzwela kwenotshi.Uma kuqhathaniswa nokuqhekeka, ukonakala kwemishini kulimaza uhlaka olucacile, ngaphandle kokufaka insimbi yokulimala kwangaphakathi, ngaleyo ndlela kuvumela okunye ukujula okujwayelekile okukhona, kodwa kwezinye zezimo ezibucayi kakhulu zohlelo lokusebenza. , ukujula kudlula inani elithile, noma amaqhuqhuva, kufanele kugaywe ukuze kuqedwe uguquko olushelela kangaka.
Ukuchezuka kosayizi ikakhulukazi ekuqondeni kwepayipi lensimbi, ukuzungeza, isici sokujiya esingalingani. Ezimweni eziningi, ukubekezelela ubuqotho bokusetshenziswa kweshubhu elikhulu lensimbi, kodwa ubuqotho bamazinga okukhiqiza amapayipi ensimbi abekwe izimfuneko, uma inani elishiwo leqiwe lingahlanganisa isizathu sokubuya, ngakho-ke, isitshalo kufanele siqashelwe.Ukubekezelela ukujikeleza kuzothinta ukusetshenziswa kwamapayipi ensimbi.
ikakhulukazi eqenjini lekhanda le-welding ohlangothini olungalungile.Ukubekezelelana kwabo okuzungezile okungalungile ngenxa yomthamo webhere wamajoyini ahlanganisiwe ngeke kunciphise kuphela, kodwa futhi kukhiqize ukuhlushwa kokucindezeleka.Iqembu endaweni yesehlakalo, ukujikeleza kwepayipi okunye kungalungiswa.Ipayipi lensimbi elinobubanzi obungaphandle lisetshenziselwa ukuchema nokubekezelela ubundingilizi ngendlela efanele. Ukujiya kodonga okungafananga ngokuvamile kulula ukuziba, futhi izindinganiso eziningi zamapayipi ensimbi azichazwa ngokucacile.Uma ukuqina kodonga olungalingani, ngeke nje kuphumele ekumisweni ohlangothini olungalungile lwelunga, kodwa futhi nasekucutshungulweni kokuguqulwa kwesibili (njengokufakwa kwepayipi lokukhiqiza ipayipi lensimbi) kuthinteke kabi.
