Iyini ipayipi lensimbi elifakwe i-galvanized?
Njengoba sonke sazi, amashubhu ensimbi acwiliswe ngokushisauhlobo lwepayipi lensimbi elakhiwe futhi eliqiniswe nge-galvanized. Ngakho-ke libizwa nangokuthi amashubhu ensimbi agqitshiwe nge-galvanized.
Kungani ipayipi lensimbi elihlanganisiwe noma ipayipi lensimbi elihlanganisiwe kuyindlela ethandwa kakhulu yokukhiqiza amapayipi ensimbi ahlanganisiwe? Isizathu ukuthi imishini edingekayo ekukhiqizeni ayibizi kakhulu futhi inqubo ingandiswa kakhulu. Ngokungafani namapayipi ensimbi ahlanganisiwe ashisayo, amashidi ensimbi ahlanganisiwe adinga isikhathi esifushane sokucubungula, okuholela kungqimba oluncane lwe-iron-zinc alloy kanye nengqimba ebanzi ye-zinc emsulwa.
Kodwa-ke, njengoba ukushisa okukhiqizwa ngesikhathi sokushiselaamapayipi ensimbi agqitshwe nge-galvanizedUma isusa ungqimba lwe-zinc ebusweni bensimbi, insimbi eveziwe kumele ivalwe kabusha kusetshenziswa inqubo yokufafaza ngokushisa kwe-zinc. Lokhu kusho nokuthi ama-weld odongeni lwangaphakathi lwepayipi ngeke ahlanganiswe nge-galvanized. Izakhiwo ze-anode ezihlatshelwe ze-zinc ziqinisekisa ukuthi ama-weld angaphakathi aveziwe awaphazamisi ukumelana nokugqwala komkhiqizo noma impilo yesevisi.
Ukufaka i-galvanizing ngaphambi kokusebenzisa insimbi kuhilela ukufaka amashidi ensimbi ku-zinc encibilikisiwe ukuze kufakwe i-coating. Ngemva kwalokho, amashidi ayasikwa abe usayizi bese efakwa kabusha. Ngesikhathi senqubo yokufaka i-galvanizing ngaphambi kokusebenzisa insimbi, ubukhulu obuthile be-zinc coating busetshenziswa kulo lonke ishidi. Isibonelo, insimbi ye-Z275 efakwe i-galvanizing ngaphambi kokusebenzisa insimbi inomphetho we-zinc ongamagremu angu-275 ngemitha yesikwele.
Uma kuqhathaniswa nensimbi egayiwe eshisayo, insimbi egayiwe kusengaphambili inikeza inzuzo enkulu ekubukekeni kwayo okuhle kakhulu. Ngaphezu kwalokho, ngokuvamile ingabizi kakhulu. Izinto ezigayiwe kusengaphambili zisetshenziswa kabanzi emikhiqizweni ehlukahlukene, kufaka phakathi amapayipi, ama-flange, kanye neziteshi eziveziwe.
Uyini umehluko phakathi kwe-pre-insimbi ehlanganisiweamapayipikanye nensimbi ehlanganisiweamapayipi?
Ukufakwa kwe-galvanization ecwiliswe ngokushisa kuhilela ukucwilisa yonke insimbi noma isakhiwo sensimbi emgodini we-zinc oncibilikisiwe, okuholela ekumbozweni okuqhubekayo ebusweni. Ukufakwa kwe-galvanization ngaphambi kokusetshenziswa kwenziwa esigabeni sokuqala, ngaphambi kokuba amashidi asikwe abe osayizi nezingcezu, ukuze imiphetho esikiwe ingambozwa.
Iqembu le-Tianjin Yuantai Derunikhiqiza amapayipi ensimbi asetshenziswe kusengaphambili ngokuhambisana ngokugcwele nezindinganiso zomhlaba wonke ezifana ne-ASTM, JIS, BS, DIN, EN, kanye ne-GB. Izinhlobo zezingxenye ezitholakalayo zifaka phakathi indilinga, isikwele, unxande, okusaqanda, kanye nezinye izimo ezikhethekile ezenzelwe wena ukuze kuhlangatshezwane nezidingo ezahlukene zesakhiwo nezezimboni.
Amashubhu angunxande agqitshwe nge-galvanized ayindinganiso yemboni yohlaka locingo, futhi asetshenziswa osonkontileka, abakhi bezakhiwo kanye nonjiniyela. Abakhi bezakhiwo kanye nabakhi bezakhiwo zezindawo basebenzise ucingo lwensimbi ukuklama izindawo zokukhosela ezahlukahlukene, amazinga okukhanyisa kanye nezithombe zokuhlobisa zezindawo zomgwaqo, amapaki, izitobhi zamabhasi kanye nezitimela ezilula, izikhungo zokuthenga, izitolo ezinkulu, izinkundla zemidlalo, izakhiwo zamahhovisi, izindawo zokupaka kanye nezinye izikhungo. Izigxobo zocingo lwensimbi ziklanywe ngokucophelela ngemigqa ehlanzekile, ubuqotho besakhiwo kanye nokulula kokufakwa. Lezi zicingo zitholakala ngokuphakama nobubanzi obuhlukahlukene ngezindlela eziningi.
Ini's theUkusetshenziswa kwepayipi lensimbi elifakwe i-galvanized kusengaphambilis?
Amapayipi ensimbi asetshenziswe ngaphambilini asetshenziswa emikhakheni eminingi, njengesakhiwo sensimbi, isakhiwo sokwakha, isitimela sokuvikela, ifenisha yensimbi njll. Imikhiqizo yethu ithunyelwa emazweni angaba ngu-45 emhlabeni jikelele, futhi sithole ukuqashelwa okukhulu kumakhasimende ethu ngekhwalithi kanye nensizakalo esiyinikezayo.
