Idatha Yomkhiqizo

Isingeniso Somkhiqizo

I-ASME B16.47 Series B (API 605) Ububanzi Obukhuluweld intamo flangeiyisakhi esimisiwe esisetshenziselwa ukuxhuma amapayipi, izinto zokusebenza namavalvu. Ngokuvamile kufanelekile ukucindezela okuphezulu nokushisa okuphezulu
Kuyindinganiso eyakhiwe yi-American Society of Mechanical Engineers (ASME), ikakhulukazi ingxenye yezinga le-ASME B16.47, elibuye laziwe ngokuthi yi-API 605 ejwayelekile.

Ibanga losayizi:

Lolu chungechunge lwama-flange lufanele osayizi bamapayipi abakhulu kakhulu, ngokuvamile ukusuka kumayintshi angu-26 (DN650) kuya ku-48 amayintshi (DN1200)

Isilinganiso Sokucindezela:

Ngokuvamile kusebenza ezilinganisweni zokucindezela okuphezulu okufana ne-Class 150 kuya ku-Class 900.

Izinga lamazwe ngamazwe:
Ama-flange we-ASME B16.47 Series B ahlangabezana namazinga e-American Society of Mechanical Engineers (ASME). Eyaziwa nangokuthi yi-API 605 ejwayelekile, iyindinganiso ye-flange eshicilelwe yiPetroleum Industry Association (API).

Isicelo:
Lolu hlobo lwe-flange luvame ukusetshenziselwa ukuxhumeka kwamapayipi ngaphansi kwengcindezi ephezulu kanye nezimo zokushisa eziphezulu emkhakheni wezimboni.
Ifanele i-petroleum, amakhemikhali, igesi yemvelo nezinye izimboni, ikakhulukazi ngezikhathi ezidinga amandla aphezulu kanye nokuvala kahle.

Izici:
1. Ukuxhumeka kwe-Butt welding: I-diameter enkulu ye-butt welding flange inentamo yokushisela, engakwazi ukushiselwa ngokuqondile ngepayipi ukuze inikeze uxhumano oluzinzile.
2. Amandla aphezulu: Ngenxa yokusetshenziswa ezindaweni ezinomfutho ophezulu kanye nokushisa okuphezulu, lawa ma-flange ngokuvamile enziwe ngezinto ezivimbela ukushisa okuphezulu, amandla aphezulu ukuze kuqinisekiswe ukusebenza nokuphepha kwawo.
3. Ukusebenza okuhle kakhulu kokuvala: Izixhumanisi ze-Flange ngokuvamile zidinga ukusebenza kahle kokuvala ukuze kuvinjelwe ukuvuza, ngakho-ke i-flange ye-butt ye-welding ye-diameter enkulu iklanyelwe indawo yokuvala ukuze kuqinisekiswe umphumela omuhle wokuvala.
4. Ifanele ukucindezela okuphezulu nokushisa okuphezulu: Ngenxa yokwakheka kwayo kanye nezici zezinto ezibonakalayo, le flange ifaneleka kakhulu ekucindezelweni okuphezulu nokushisa okuphezulu kwezicelo.

Okuhle nokubi:
Inzuzo:

1. Ifanele umfutho ophezulu kanye nezinga lokushisa eliphezulu:

Le flange ifanele izicelo eziningi zezimboni ezinomfutho ophezulu kanye nokushisa okuphezulu, okungaqinisekisa ukuxhumana okuphephile nokuthembekile.

2. Amandla aphezulu:

Ama-flange wokushisela izinqe ezinobubanzi obukhulu enziwe ngezinto ezikwazi ukumelana nokushisa okuphezulu, ezikwazi ukumelana nezimo zokusebenza ezinzima.

3. Ukubekwa uphawu okuhle:

Idizayinelwe ngendawo yokuvala, enganikeza umphumela wokuvala ongcono futhi inciphise ingozi yokuvuza.

Ukubi

1. Izindleko eziphakeme:

Ngenxa yomklamo wayo okhethekile kanye nezinto ezisetshenziswa amandla aphezulu, le flange ingase ibize kakhulu kunezinye izinhlobo zama-flange.

2. Ukufakwa nokugcinwa okuyinkimbinkimbi:

Izixhumanisi zokushisela izinqe zidinga amakhono okushisela, futhi ukufakwa nokulungiswa kungase kudinge ulwazi namathuluzi ochwepheshe okwengeziwe.

Kafushane, i-ASME B16.47 Series B (API 605) I-Large Diameter Weld Butt Flange iyingxenye yokuxhumana esezingeni elifanele indawo yokucindezela okuphezulu nezinga lokushisa eliphezulu, futhi ukwakheka kwayo nezici kuyenza ibe ukukhetha okuthembekile ekuxhumekeni kwamapayipi, kodwa kukhona futhi ukucatshangelwa Izindleko zayo kanye nobunkimbinkimbi bokufakwa nokugcinwa. Cabangela ngokucophelela izidingo zohlelo lokusebenza futhi ulandele izindinganiso ezifanele kanye nokucaciswa ngaphambi kokusetshenziswa.
