Iningi lamapayipi ayisikwele ngamapayipi ensimbi, kantiamapayipi esikwele agqitshwe ngokushisazimbozwe ngengqimba ye-zinc ebusweni bamapayipi ensimbi ngenqubo ekhethekile. Okulandelayo, sizochaza ngokuningiliziwe ukuthi singayixazulula kanjani inkinga yokugqwala kwamapayipi ayisikwele agqitshwe nge-galvanized.
Isinyathelo sokuqala ukungqongqoza: ukuze kube lula ukukhulula inathi, kubalulekile ukungqongqoza kancane ipayipi lesikwele eligobile elingu-304 ngesando esiphezulu sesikwele. Ifektri yamapayipi esikwele agandayiwe kufanele ihlanganise ulwazi ngokufanele. Uma inathi iyinsimbi ephonswe ngensimbi, idinga ukuba lukhuni kancane. Ipayipi lesikwele eligandayiwe le-Q345B kanye nezingxenye zepulasitiki ezijwayelekile zidinga ukungqongqozwa ngobumnene kuphela. Uma kungenjalo, sebenzisa isando ukuze ujikeleze uye ohlangothini lokungqongqoza i-304.ipayipi lesikwele elihlanganisiwe elingenamthungo.
Isinyathelo sesi-2: ungasebenzisi isikrufu ukuze uqinise isikrufu sensimbi engagqwali esigqwali ukuze ugweme ukuphula isikrufu sensimbi engagqwali noma ukulimaza isikrufu. Ngalesi sikhathi, kuyadingeka ukusebenzisa isando sensimbi ukuze ushukumise isibambo sesikrufu ukuze izikrufu zensimbi engagqwali ezigqwali zikwazi ukukhunyulwa kalula.
Isinyathelo sesithathu ukushaya ngesibhakela: ngezinye izikhathi ipayipi lesikwele elihlanganisiwe elingama-304 lizophazamiseka ngenxa yokugqwala. Ipayipi lesikwele elihlanganisiwe - ipayipi lesikwele elihlanganisiwe - ipayipi lesikwele elihlanganisiwe elishisayo - ipayipi lesikwele elihlanganisiwe - imboni yepayipi lesikwele elihlanganisiwe - imboni yepayipi lesikwele elihlanganisiwe -Ifektri yepayipi yesikwele yeTianjin egayiweAwukwazi ukuyisusa ngesiphandla noma ngesiphandla sentambo. Ngalesi sikhathi, kusetshenziswa "indlela yokuthinta". Iyini "indlela yokuthinta"? Iwukuthinta "umsele omise okwe-U" ohlangothini oluqondile lwepayipi lesikwele elihlanganisiwe elingu-304 ngesando sensimbi kanye nesando se-turbine. Ifektri yamapayipi esikwele ahlanganisiwe kufanele ihlanganise ulwazi bese ilungisa i-engeli yekhoni yokubhoboza. Ipayipi lesikwele elihlanganisiwe le-Q345B lingavulwa ngemva kokuba uwoyela ungene.
Isinyathelo sesine siyasha: lapho i-304 ihlanganiswe nge-galvanized engenamthungoipayipi eliyisikweleigqwalile, futhi ayikho kulezi zindlela ezingenhla esebenzayo, uhlobo "lokuhlasela komlilo" luzosetshenziswa. Manje, izikulufo namantongomane ziyosiwe nge-gas welding oxidation flame. Ngemva kokuba ubuso bushisiwe bubomvu, uwoyela omncane uyawa. Indlela "yokwandisa ukushisa kanye nokuncipha okubandayo" isetshenziswa ukwandisa igebe phakathi kwenduku yesikulufo kanye nepayipi lesikwele eligoqiwe elingagoqiwe elingama-304. Ipayipi lesikwele eligoqiwe elingama-304 elingagoqiwe lingavulwa ngemva kokuba uwoyela ugeleze.
Isikhathi sokuthunyelwe: Agasti-23-2022
