I-347 Insimbi Engagqwali Ukumelana Kahle Kokugqwala, Le Grainger evunyelwe i-Weld Fight Flange ifakwe ohlelweni nge-Beldferial Weld entanyeni. Indawo ye-welded ingahlolwa kalula yi-radiography. Ipayipi elifanisiwe ne-Flange Brore inciphisa isiyaluyalu nokuguguleka ngaphakathi kwepayipi. I-Flange ihle kakhulu ukuze isetshenziswe kuzinhlelo zakho ezibucayi futhi ilungele ukusetshenziswa ngomoya, amanzi, uwoyela, igesi yemvelo kanye nomusi.

Ukuvuselelwa kuyindlela yokuxhuma amapayipi, ama-valve, amaphampu neminye imishini yokwakha uhlelo lwamapayipi. Kusiza nokuhlanza, ukuhlola noma ukuguqulwa. Ama-flanges ajwayele ukufakwa noma afakwe.

I-Flange yizingxenye ezixhumanise amaphayipha amabili, ukuxhumana kwe-flange kuchazwa yi-flange, i-gasket kanye ne-bolt ezintathu zixhumeke njengeqembu lesakhiwo esihlanganisiwe sokwenza uphawu okuhlangene. I-gasket yengezwa phakathi kwama-flanges amabili bese iboshwe ngama-bolts. I-Flange ye-Flange ehlukile, ubukhulu bahlukile, futhi ama-bolts abawahlukile ahlukile, lapho i-pump ne-valve xhuma ngepayipi le-flange, lolu hlobo lwezinto ezivuthiwe nalo lungenziwa nge-flange ne-flange pay, njengokuxhumana phakathi kwe-flange nephampu yamanzi, akunjalo I-Inapposite ukubiza ipompo yamanzi njengezingxenye zohlobo lwe-flange, kepha isihlobo esincane esincane, ingabizwa njengezingxenye zohlobo lwe-flange.

Insimbi engagqwali 316 \ 16l flanges ingenziwa ngokushisa okushisayo noma ngokuphonsa. Ama-flate epuleti ayimpumputhe noma ashelelayo ngaphandle kwama-hubs angafakwa emnyani ngokuqondile epuletini.
