Ngowuphi umahluko ophambili phakathi kwe-ASME B16.5 kunye ne-ASME B16.47

I-ASME B16.5 kunye ne-ASME B16.47 zimbini zemigangatho eqhelekileyo yaseMelika yeeflange. Nangona kunjalo, abantu abaninzi abakwazi ukwahlula le migangatho mibini, ngoko bahlala beyisebenzisa ngokungalunganga le migangatho mibini. Eli nqaku liza kwenza umahluko othile phakathi kwale migangatho mibini.

Umahluko ophambili kukuba uluhlu lwecaliber ye-flange ebandakanyiweyo kwimigangatho eyahlukeneyo yahlukile.

I-ASME B16.5 ibandakanya imilinganiselo ye-NPS1/2 ukuya kwi-NPS24 (okt 1/2 intshi ukuya kwi-intshi engama-24) phantsi kweklasi yoxinzelelo CL150-CL2500;
I-ASME B16.47 ngumgangatho we-flanges yobubanzi obukhulu, kubandakanywa nobukhulu be-NPS26 ukuya kwi-NPS60 phantsi koxinzelelo lwe-Class75-Class900.
I-ASME B16.47 yohlulwe yangamacandelo amabini, angala uthotho A kunye nothotho B

Malunga nomahluko phakathi kwezi zintlu zimbini:

ASME B16.47 Series A umthombo MSS SP-44, kunye Series B umthombo API 605.
Series A ububanzi ububanzi flange, kwaye Series B yi flange umbhobho
Uluhlu: iibholiti ezinkulu zemingxuma, ubungakanani obuncinci
Uchungechunge lwe-B: iibholiti ezincinci zomngxuma, ubuninzi obukhulu

Ubungakanani bombhobho phakathi kochungechunge lwe-A kunye no-B luyafana, kodwa ubungakanani bokudibanisa buhluke, obufuna ukukhethwa ngokweyona meko.
Ngokubanzi, uchungechunge B lusetyenziswa ngakumbi kwimibhobho, njenge-SH3406 kunye ne-HG20615 e-China, zonke zivela kwi-ASME B16.47 B (AP1 605). Ukhetho lusekelwe ikakhulu kwiimfuno zabo zoyilo. Ngaphandle kwemimiselo ekhethekileyo, ubukhulu obuncinci bukhethwa ngokubanzi. Ngapha koko, ixabiso liphantsi ngokwentelekiso.

Ngokomgangatho we-ASME B16.47, sifumanise ukuba zimbini kuphela iindidi zeeflange kwiimveliso zeflange ezisebenzayo kulo mgangatho:ukuwelda intamo flangekwayeiflange eyimfama.

Nantsi eminye imifanekiso ukubonisa umgangatho ASME B16.47 ngokweenkcukacha. Ndiyakholelwa ukuba ungayifumana impendulo echanekileyo apha.

I-American standard flange enkulu ye-ASME B16.47 umbhobho omkhulu wentsimbi, umgangatho weflange we-American usetyenziswa ngokubanzi kwizixhobo ezithunyelwa kumazwe angaphandle okanye kumashishini angaphandle. Imigangatho yolawulo yeFlange eqhelekileyo yaseMelika: ANSIB16.5, ASME B16.47, i-American standard flange caliber ibonakaliswa ngee-intshi (umz. 1 “1-1/2”, 2 “3”, “, 8″, 10,12 “, 1416 ″, 18 “, 20″ 24” 8, njl.) Umgangatho woxinzelelo we-flange waseMelika uphawulwe ngeeklasi ze-6 zoxinzelelo, ezizezi Class 150; Iklasi 300; Iiklasi 600; Iiklasi 900; Iklasi1500; I-Class 2500 yaseMelika i-flange esemgangathweni yinxalenye yokudibanisa imibhobho kunye nemibhobho, edibeneyo ekupheleni kombhobho. Ukudityaniswa kwe-flange okanye i-flange joint ibhekiselele kwindlela yokudibanisa edibeneyo edityaniswe yi-flange, i-gasket kunye ne-bolt njengeqela lesakhiwo sokutywinwa esidityanisiweyo. Umgangatho waseMelika iflange enkulu enkulu ye-ASME B16.47 umbhobho omkhulu obubanzi bentsimbi umgangatho ulungelelaniswe kwaye unikwe yi-Ningbo Xinggang Pipeline Equipment Co., Ltd. i-flange (WNF), i-flange ephothiweyo ye-NPT), i-American standard flange cover i-flange eyimfama, i-Class series carbon steel kunye nentsimbi ye-American standard flange.
