I-ANSI B16.5: I-Pipe Flanges kanye ne-Flanged Fittings

I-ANSI B16.5 iyindinganiso eshicilelwe yi-American National Standards Institute (ANSI) enesihloko esithi “Ipayipi LensimbiAma-Flanges kanye ne-Flange Fittings– Pressure Classes 150, 300, 400, 600, 900, 1500, 2500 “(Pipe Flanges and Flanged Fittings NPS 1/2 through NPS 24 Metric/Inch Standard).

Leli zinga liphinde licacise izidingo zobukhulu, izilinganiso zengcindezi, izinto zokwakha kanye nokuhlolwa kwama-flange amapayipi ensimbi kanye nokufakwa kwe-flange okuhlobene kokuxhuma nokuhlanganisa amasistimu amapayipi.

Ama-flange ajwayelekile asebenzisa leli zinga yilena: i-welding neck flange, isiliphu ku-hubbed flange, i-flange yokushisela eyisicaba, i-blind flange,I-socket welding flange, i-flange enentambo,i-anchor flangefuthii-sleeve flange evulekile.

Izinga le-ANSI B16.5 lingelinye lamazinga e-flange asetshenziswa kakhulu kubunjiniyela bamapayipi.Icacisa ama-flange anamazinga ahlukene wokucindezela ukuze ahlangabezane nezimo ezihlukene zokusebenza nezidingo.Lawa ma-flange angasetshenziswa ukuxhuma amapayipi, ama-valve, imishini kanye nezinye izingxenye emikhakheni ehlukahlukene yezimboni, kuhlanganise ne-petroleum, amakhemikhali, igesi yemvelo, amandla kagesi, njll.

Okuqukethwe okuyinhloko nezici:
1.Ibanga losayizi: I-ANSI B16.5 indinganiso icacisa ububanzi bobubanzi bamapayipi ensimbi, amboze ububanzi obuncane ukusuka ku-1/2 intshi (15mm) ukuya kumayintshi angu-24 (600mm), futhi ihlanganisa ukucindezela okulinganiselwe okuvela ku-150 psi (PN20) kuya ku-2500 psi (PN420) izilinganiso zokucindezela.

2.Isilinganiso sokucindezela: Izinga lichaza ama-flange anezilinganiso zokucindezela ezihlukene, ezihambisana nengcindezi yokusebenza ehlukene nezimo zezinga lokushisa.Izilinganiso zengcindezi evamile zifaka u-150, 300, 600, 900, 1500, kanye no-2500, phakathi kokunye.

3.Izimfuneko zezinto ezibonakalayo: Izinga libeka ukwakheka kwamakhemikhali okuhambisanayo, izakhiwo zemishini kanye nezidingo zempahla ebonakalayo yezinto zokwakha zama-flange, okuhlanganisa i-carbon steel, insimbi engagqwali, i-alloy steel, njll.

4.Izidingo zokuklama: Izinga licacisa izidingo zokuklama ze-flange, njengobukhulu be-flange, inombolo nobubanzi bezimbobo zamabhawodi axhumayo, njll.

5.Ukuhlola: Izinga lidinga ukuthi ama-flange ahlolwe okuhlukahlukene phakathi nenqubo yokukhiqiza ukuze kuqinisekiswe ukuthi ahlangabezana nezidingo kanye nokuqinisekisa ukuphepha nokuthembeka kokuxhuma.

Okuqukethwe kwezinga le-ANSI B16.5 kubanzi kakhulu.Inikeza isiqondiso esibalulekile kanye nokucaciswa konjiniyela, abaklami nabakhiqizi ukuze baqinisekise ukuthi ukuxhunywa nokuhlangana kwezinhlelo zamapayipi kuhlangabezana nezindinganiso nezimfuneko eziqinile.Ekusetshenzisweni okungokoqobo, uhlobo olufanele lwe-flange kanye nokucaciswa kufanele kukhethwe ngokuya ngezidingo ezithile zobunjiniyela kanye nezimo zokuklama ukuze kuqinisekiswe ukusebenza okuvamile kohlelo lwamapayipi.
