I-galvanizing inqubo yokufaka ungqimba oluvikelayo lwe-zinc ensimbi noma ensimbi ukuvimbela ukugqwala.Le nqubo ijwayele ukusetshenziswa uma kwakhiwa amapayipi, ikakhulukazi lawo asetshenziswa ezimbonini ezihlukahlukene ezifana nezokwakha, uwoyela negesi, kanye nokuhlinzekwa kwamanzi.Amazinga okugalela amapayipizibalulekile ekuqinisekiseni ikhwalithi nokuqina kwamapayipi anamathangi.Ake singene emininingwaneni yamazinga okuphehla amapayipi nokuthi asho ukuthini kulayini wokuphehla amapayipi.
Ukufakwa kwamapayipiamazinga abekwe ngokuyinhloko yinhlangano yamazwe ngamazwe yaseMelika Society for Testing and Materials (ASTM).I-ASTM ibeka izindinganiso ezithile zenqubo yokufaka uthayela, okuhlanganisa ukushuba kongqimba olunothayela, ukunamathela kokunamathela, kanye nekhwalithi iyonkeothayelaphezulu.Lawa mazinga abalulekile ekugcineni ubuqotho bepayipi likathayela kanye nokuqinisekisa ukusebenza kwawo ezintweni ezihlukahlukene.
Enye yezindinganiso ezibalulekile zepayipi likathayela i-ASTM A123/A123M, ecacisa izidingo zokumbozwa kukathayela emikhiqizweni yensimbi, okuhlanganisa namapayipi.Leli zinga libonisa ubuncane bokujiya obuncane, ukunamathela kanye nokuqeda kwepayipi likathayela.Iphinde inikeze imihlahlandlela yokuhlolwa nokuhlolwa kweezinengilazi zikathayelaukuqinisekisa ukuthotshelwa kwamazinga.
In imigqa yokufaka amapayipi, ukuhambisana namazinga e-ASTM A123/A123M kubalulekile ekukhiqizeni ipayipi lekhwalithi ephezulu.Inqubo yokufaka uthayela ngokuvamile ihilela izigaba ezimbalwa, ezihlanganisa ukwelashwa okungaphezulu, ukucwenga kwediphu eshisayo kanye nokucutshungulwa.Isigaba ngasinye kufanele sihambisane nezindinganiso ze-ASTM ukuze sifinyelele ubukhulu obudingekayo kanye nekhwalithi.
Ukulungiswa kwendawo kuhlanganisa ukuhlanza amapayipi ukuze kukhishwe noma yikuphi ukugqwala, isikali noma okunye ukungcola okungase kuvimbele ukugqwalagalvanizingungqimba ekubambeleleni.Lesi sinyathelo sibalulekile ukuqinisekisa ukunamathela okufanele kwe-enamathela likathayelaendaweni yepayipi.Inqubo yokufaka uthayela wediphu eshisayo ihlanganisa ukucwiliswa kwamapayipi ahlanziwe ebhavini le-zinc encibilikisiwe, elibopha ngensimbi ensimbi ukuze kwakhe ukunamathela okuvikelayo..
Ngemuva kwenqubo ye-galvanizing, ipayipi izokwenziwa ngemuva kokucubungula, okungabandakanya ukucisha, ukudlula noma ukuhlola ukushuba kokunamathela nokunamathela.Lezi zinyathelo zangemva kokucubungula zibalulekile ukuze kuqinisekiswe ukuthi ipayipi elinothayela liyahlangabezana nezidingo zezindinganiso ze-ASTM futhi lilungele ukusetshenziswa ezinhlotsheni zezinhlelo zokusebenza.
Ukuhambisana nayoipayipi galvanizingizindinganiso aziqinisekisi kuphela ikhwalithi nokuqina kwepayipi, kodwa futhi kunomthelela ekusebenzeni kwayo isikhathi eside kanye nokumelana nokugqwala.Ipayipi elinothayela elihambisana ne-ASTM lilungele indawo yangaphandle, enomswakama ophezulu kanye negqwala, okulenza lilungele ukusetshenziswa okufana nokusatshalaliswa kwamanzi, ukusekelwa kwesakhiwo kanye nezinhlelo zamapayipi ezimbonini.
Kafushane, izindinganiso zokuphehla amapayipi ezichazwe yi-ASTM International zidlala indima ebalulekile emgqeni wokukhiqiza wokuvuthela amapayipi.Ukuhambisana naleli zinga kuqinisekisa lokhoipayipi likathayelaihlangabezana nezidingo ezidingekayo zokuqina kwe-coating, ukunamathela kanye nekhwalithi iyonke.Ngokulandela izindinganiso ze-ASTM,abakhiqiziingakhiqizaipayipi likathayela eliphezuluehlinzeka ngokuvikelwa kokugqwala okuphakeme kanye nempilo yesevisi ezinhlotsheni ezihlukene zezimboni nezentengiso.
