Ipayipi lensimbi elishisayo-dip liyinto evamile yokwakha enezici zokumelana nokugqwala, ukumelana nokugqoka, nokuphila isikhathi eside. Ngakho-ke, enziwa kanjani amapayipi ensimbi ediphu ashisayo?

1. Ukulungiswa kwempahla eluhlaza: Impahla eyinhloko yepayipi lensimbi elicwebezelayo elishisayo yipayipi elivamile le-carbon steel. Phakathi nenqubo yokukhiqiza, okokuqala udinga ukukhetha impahla yensimbi efanele futhi uqinisekise ukuthi ikhwalithi yayo ihlangabezana nezindinganiso ezifanele.

2. Ukwelashwa kwangaphambili kwepayipi lensimbi: Ngaphambi kokufakwa uthayela wediphu eshisayo, ipayipi lensimbi lidinga ukudlula uchungechunge lwezinqubo zokwelashwa kwangaphambili. Okokuqala, ipayipi lensimbi liyacoliswa, bese kukhishwa ukugqwala ukuze kukhishwe ama-oxide, amafutha nokunye ukungcola phezulu. Bese, hlanza ipayipi lensimbi ukuze uqinisekise ukuhlanzeka kwendawo. Lokhu kuzokulungiselela inqubo elandelayo yokufaka uthayela.

3. Inqubo yokufaka uthayela: I-Hot-dip galvanizing iyinqubo lapho amapayipi ensimbi ecwiliswa oketshezini oluncibilikisiwe lwezinc ukuze akhe ungqimba lwezinc ngaphezulu. Inqubo ethize yokugalela amanzi ihlanganisa lezi zinyathelo ezilandelayo:
a. I-Pickling: Ipayipi lensimbi elifakwe ngaphambili licwiliswa kwisisombululo se-asidi sokwelashwa kokukhetha ukukhipha ama-oxide nokungcola phezulu. Lesi sinyathelo sisiza ukuthuthukisa ukunamathela kwesendlalelo sama-galvanized ebusweni bepayipi yensimbi.
b. Ukucwiliswa emanzini: Gxilisa ipayipi lensimbi elifakwe emanzini anosawoti kusixazululo se-ammonium chloride esishisiwe. Lesi sinyathelo sisiza ukususa ama-oxide ebusweni bepayipi lensimbi futhi sinikeze isisekelo esihle sokugalela ama-galvanizing okulandelayo.
c. Ukomisa: Khipha ipayipi lensimbi elicwilisiwe esixazululo bese uyomisa ukuze ususe umswakama phezulu.
d. Ukushisa: Thumela ipayipi lensimbi elomisiwe esithandweni sokushisa ngaphambi kokwelashwa. Ukulawulwa kwezinga lokushisa langaphambi kokushisa kubalulekile kumthelela olandelayo wokugalela amathi.
e. Ukugalela umpheme: Gxilisa ipayipi lensimbi elishisiwe kuqala oketshezini lwezinki oluncibilikisiwe. Oketshezini lwezinki, insimbi engaphezulu kwepayipi lensimbi ihlangana ne-zinc ukuze yakhe ingxube ye-zinc-iron alloy. Lesi sinyathelo sidinga ukulawula isikhathi nokushisa kwe-galvanizing ukuqinisekisa ukufana kanye nekhwalithi yokugqoka.
f. Ukupholisa: Ipayipi lensimbi elithathiwe likhishwa oketshezini lwezinki bese lipholiswa. Inhloso yokupholisa ukuqinisa ukunamathela nokuthuthukisa ukunamathela kwayo.

4. Ukuhlola nokupakishwa: Amapayipi ensimbi ayisithako adinga ukuhlolwa ukuze kuqinisekiswe ukuthi izinga lawo lihlangabezana nezindinganiso ezifanele. Okuqukethwe kokuhlola kuhlanganisa ikhwalithi yokubukeka, ukujiya kwengubo, ukunamathela, njll. Amapayipi ensimbi afanelekayo azopakishwa ukuze avimbele ukulimala ngesikhathi sokuthutha kanye nokusetshenziswa.

Inqubo yokukhiqiza amapayipi ensimbi ashisayo-dip iyinkimbinkimbi futhi idinga izinqubo eziningi. Kodwa-ke, le nqubo inganikeza amapayipi ensimbi ngezindawo ezinhle kakhulu zokulwa nokugqwala nokubukeka okuhle, okuwenza asetshenziswe kabanzi ekwakhiweni, ezokuthutha, kumakhemikhali e-petrochemicals, nakweminye imikhakha.

Ukufingqa, inqubo yokukhiqiza amapayipi ensimbi ediphu ashisayo ihlanganisa ukulungiswa kwempahla eluhlaza, ukulungiswa kwepayipi lensimbi, inqubo yokufaka uthayela, ukuhlolwa, nokupakishwa. Ngalezi zinyathelo zenqubo, amapayipi ensimbi ashisayo anekhwalithi ethembekile angenziwa ukuze ahlangabezane nezidingo zamaphrojekthi wobunjiniyela ahlukahlukene. Ipayipi lensimbi elicwebezelayo elishisayo seliphenduke enye yezinto ezibalulekile emkhakheni wokwakha ngenxa yezindawo zalo ezinhle kakhulu zokulwa nokugqwala nokubukeka okuhle. Ekuthuthukisweni kwesikhathi esizayo, ngokuthuthuka okuqhubekayo kanye nokuthuthukiswa kobuchwepheshe bezinqubo, inqubo yokukhiqiza amapayipi ensimbi ediphu ashisayo izophinde ithuthukiswe ngokuqhubekayo ukuze inikeze izixazululo ezingcono zokufaka izicelo emikhakheni eminingi.
