Amapayipi ensimbi amapayipi ensimbi okuhamba ngawo izintambo zikagesi nezintambo

Amapayipi ensimbi amapayipi ensimbi okuhamba ngawo izintambo zikagesi nezintambo.Inikeza ukuvikeleka okubalulekile ezintanjeni nasezintanjeni ekulimaleni nakunoma yimiphi imithelela.
I-Henfen ihlinzeka ngamashubhu epayipi ekhwalithi ahlanganiswe nge-zinc ngokufanayo, idiphu elishisayo elikhanyiswe ngaphakathi nangaphandle.Kwenziwe ku-BS 4568 EN-BS31-1940.
Futhi, i-Henfen inikeza izinhlobonhlobo zezinsiza ze-conduit zensimbi.
I-Henfen ihlinzeka ngezinhlobo ezimbili zamapayipi othayela avamile: izinga laseBrithani kanye nezinga laseMelika.Izindinganiso eziyinhloko zaseBrithani yi-BS4568 kanye ne-BS31-1940.Ubukhulu ngokuyinhloko 20mm, 25mm, 32mm.Lawa mapayipi ensimbi angashiselwa, kodwa adinga ukunaka umsebenzi wezandla.Ngemva kokushisela, ipayipi likathayela kufanele lipholishwe, ngaphandle kwalokho ikhwalithi izothinteka, futhi kuzokwenzeka amabhamuza noma ukugqwala okukhulu.Amapayipi anamakha asetshenziselwa ikakhulukazi ukuvikela izintambo nezintambo.Iningi lezindlu ezindala zisebenzisa amapayipi anathayela.Manje ipayipi lika-galvanized lisetshenziselwa igesi kanye nokufudumeza.
Yiziphi izici zepayipi elinothayela?
1. Izindleko eziphansi zokucubungula: Izindleko zokulwa nokugqwala kwe-hot-dip galvanizing ziphansi kunamanye amapende nama-coatings, futhi izindleko ziphansi kakhulu.
2. Ihlala isikhathi eside: Ingaphezulu lepayipi lensimbi elidiphu elishisayo likhanya ngokukhethekile, ungqimba lwezinc lufana, aluvuzi, aluconsi, lunamathela oluqinile nokumelana nokugqwala okuqinile.Indawo engaphansi kwedolobha ikhuphuke kakhulu, futhi ugqinsi olujwayelekile lwe-hot-dip galvanized anti-corrosion ngokuvamile lungagcinwa iminyaka engaphezu kwengu-50 ngaphandle kokunakekelwa.Ezindaweni zasemadolobheni noma phesheya kwezilwandle, ungqimba olujwayelekile lwe-hot-dip galvanized anti-corrosion lungagcinwa iminyaka engaba ngu-20 ngaphandle kokulungiswa.
3. Ukuthembeka okuhle: Ungqimba olungaphezulu lwepayipi elithathiwe luhlanganiswe ngensimbi nensimbi, futhi ipayipi lensimbi elakhiwe lakhiwe phezu kwensimbi, ngakho-ke ukuqina kwe-coating kuqhathaniswa nokwethenjelwa.
4. I-coating inokuqina okuqinile: i-zinc coating yakha isakhiwo esikhethekile se-metallographic, esingamelana ngokujwayelekile nokulimala komshini ngesikhathi sokuthutha nokusetshenziswa.
5. Ukuvikelwa okuphelele: Yonke ingxenye yezingxenye zesiliva nayo ingafakwa uthayela, ngisho nezindlu zangasese, amakhona acijile nezindawo ezicashile zingavikelwa ngokugcwele.
6. Yonga isikhathi nabasebenzi: Inqubo yokufaka ama-galvanizing ishesha kunezinye izindlela zokwakha zokumboza, ezingagwema isikhathi esidingekayo sokudweba endaweni yokwakha ngemva kokufakwa.
