ASME/ANSI B16.5 Stainless Steel Carbon Steel Welding Neck Flange

Idatha Yomkhiqizo

Isingeniso Somkhiqizo

I-ASME B16.5 ne-ANSI B16.5 izindinganiso zamapayipi ensimbi kanye noxhumo lwe-flange, asetshenziselwa ukucacisa izidingo zosayizi, umklamo, impahla kanye nokuhlolwa kwama-flange asetshenziswa ezinhlelweni zamapayipi.
I-ASME iyindinganiso ye-American Society of Mechanical Engineers, futhi i-ANSI iyi-American National Standard, lawa mazinga amabili empeleni ayizinguqulo ezimbili zezinga elifanayo.Lezi manje zivame ukubizwa ngokuthi amazinga e-ASME/ANSI B16.5

I-Welding neck flange ibizwa nangokuthi i-neck welding flange, eyakhiwe izingxenye ezinhlanu: intamo, i-flange surface, i-screw hole, ibhawodi kanye namantongomane, kanye ne-gasket yokuvala.Idivayisi yokuxhuma i-Lan, evame ukusetshenziselwa ukuxhuma amapayipi, ama-valve, izinto zokusebenza nezinye izingxenye.

1. Intamo: Eyaziwa nangokuthi i-welding neck, iyingxenye ye-flange, ngokuvamile eyakhiwe ingxenye yentamo ye-cylindrical, futhi ukwakheka kwayo kunezinhlobo ezimbili:intamo ende nentamo emfushane.Khetha uhlobo olufanele ngokwezidingo zokusetshenziswa.
2. I-Flange surface: Ingxenye exhunywe kwipayipi noma impahla, ngokuvamile indawo eyindilinga eyisicaba noma ephakanyisiwe.
3. I-Screw Hole: Itholakala onqenqemeni lwe-flange surface, isetshenziselwa ukufaka ama-bolts, ukuxhuma nokulungisa i-flange.
4. Amabhawodi namantongomane: asetshenziselwa ukuxhuma nokulungisa ingxenye enentambo phakathi kwama-flange amabili.
5. I-gasket yokuvala: Ifakwe phakathi kobuso obubili be-flange ukuze kuqinisekiswe ukusebenza kokuvala uxhumano.

Izici:
1. Ukusebenza okuhle kakhulu kokuvala: Ukucutshungulwa kwentamo kanye nesakhiwo sendawo yokubeka uphawu kunganikeza ukusebenza okuthembekile kokubeka uphawu, okulungele ukucindezela okuphezulu kanye nezindawo zokushisa eziphezulu.
2. Umthamo omuhle wokuthwala: Isakhiwo sentamo singanikeza umthamo ongcono wokuthwala, okwenza kube ukufaneleka kokucindezela okuphezulu kanye nezimo zokusebenza eziphezulu zomthwalo.
3. Kulula ukufaka: uxhumano lwe-welding lunamandla, impilo yesevisi yinde, futhi akulula ukuyikhulula.
4. Isicelo esibanzi: i-neck butt welding flange inamandla okuthwala aqinile nokusebenza kokuvala, futhi ibuye isetshenziswe ngokujwayelekile kumaphrojekthi anengcindezi ephezulu, izinga lokushisa eliphezulu noma izidingo zokubeka uphawu.Isibonelo, ivame ukusetshenziswa ku-petroleum, amakhemikhali, igesi yemvelo, amandla kagesi nakweminye imikhakha yezimboni.

Uma usebenzisa i-weld neck flange, kuyadingeka ukubeka lezi ezimbilii-flangeizingxenye ekugcineni kokuxhuma kwepayipi noma izinto zokusebenza okufanele zixhunywe, bese uzilungisa ndawonye ngokufaka i-welding entanyeni.Ngesikhathi sokuxhuma, i-gasket yokuvala kufanele ifakwe ngendlela efanele ukuze kuqinisekiswe ukuthi akukho ukuvuza okwenzekayo ekuxhumekeni.
