Ama-blind flange ayingxenye ebalulekile ezinhlelweni zamapayipi, ngokuvamile asetshenziselwa ukuvala izimbobo zamapayipi noma imikhumbi ukuze ilungiswe, ihlolwe, noma ihlanzwe.Ukuze kuqinisekiswe ikhwalithi, ukuphepha kanye nokushintshashintsha kwama-blind flanges, i-International Organization for Standardization (ISO) kanye nezinye izinhlangano ezisezingeni elifanele zikhiphe uchungechunge lwezindinganiso zamazwe ngamazwe ezihlanganisa zonke izici zokuklama, ukukhiqizwa nokusetshenziswa kwama-blind flange.
Nawa amanye amazinga asemqoka wamazwe ngamazwe ahlobene nama-blind flanges kanye nokuqukethwe kwawo:
I-ASME B16.5- Amapayipi amapayipi - Ingxenye 1: Ama-flange ensimbi wezimboni kanye namapayipi esevisi evamile: Leli zinga lihlanganisa izinhlobo ezihlukahlukene zama-flange, kuhlanganise nama-blind flange.Lokhu kufaka phakathi ubukhulu, ukubekezelelana, ukuma kwendawo yokuxhumana kanye nezidingo zempahla ye-flange ye-blind flange.
I-ASME B16.48-2018 - I-Line Blanks: Indinganiso eshicilelwe yi-American Society of Mechanical Engineers (ASME) ehlanganisa ngokuqondile ama-flange angaboni, okuvame ukubizwa ngokuthi "izikhala zemigqa."Leli zinga licacisa ubukhulu, izinto ezisetshenziswayo, ukubekezelela kanye nezidingo zokuhlola zama-blind flanges ukuze kuqinisekiswe ukwethembeka kwawo ekufakweni kwamapayipi esevisi yezimboni kanye nesevisi evamile.
EN 1092-1:2018 - Ama-Flanges namajoyinti awo - Ama-flange ayindilinga amapayipi, ama-valve, okokufakwayo nezinye izinto, i-PN eqokiwe - Ingxenye 1: Ama-Flange ensimbi: Leli izinga laseYurophu elihlanganisa umklamo, ubukhulu, izinto zokwakha kanye nezidingo zokumaka.Ilungele izinhlelo zamapayipi eFrance, eJalimane, e-Italy nakwamanye amazwe aseYurophu.
I-JIS B 2220:2012 - Amapayipi ensimbi: I-Japanese Industrial Standard (JIS) icacisa ubukhulu, ukubekezelela kanye nezidingo zempahla zama-blind flange ukuze kuhlangatshezwane nezidingo zamasistimu amapayipi ase-Japan.
Izinga ngalinye lamazwe ngamazwe lihlanganisa okulandelayo:
Ubukhulu nokubekezelelwa: Izinga licacisa ububanzi besayizi wama-blind flange kanye nezidingo zokubekezelelana ezihlobene ukuze kuqinisekiswe ukushintshana phakathi kwama-blind flange akhiqizwa abakhiqizi abahlukene.Lokhu kusiza ukuqinisekisa ukuvumelana nokushintshana kwamasistimu amapayipi.
Izidingo zezinto ezibonakalayo: Izinga ngalinye licacisa izindinganiso zezinto ezibonakalayo ezidingekayo ukuze kwenziwe ama-blind flanges, ngokuvamile i-carbon steel, insimbi engagqwali, i-alloy steel, njll. Lezi zidingo zifaka ukwakheka kwamakhemikhali wento, izakhiwo zemishini kanye nezidingo zokwelashwa kokushisa ukuze kuqinisekiswe ukuthi i-blind flange inayo amandla anele nokumelana nokugqwala.
Indlela yokukhiqiza: Amazinga ngokuvamile ahlanganisa indlela yokukhiqiza ama-flange ayimpumputhe, okuhlanganisa ukucubungula impahla, ukubunjwa, ukushisela nokwelashwa kokushisa.Lezi zindlela zokukhiqiza ziqinisekisa ikhwalithi nokusebenza kwama-blind flanges.
Ukuhlola nokuhlola: Izinga ngalinye liphinde lihlanganise nezidingo zokuhlola nokuhlola ama-blind flanges ukuze kuqinisekiswe ukuthi angasebenza ngokuphepha nangokuthembekile ekusetshenzisweni kwangempela.Lezi zivivinyo ngokuvamile zihlanganisa ukuhlolwa kwengcindezi, ukuhlolwa kwe-weld, nokuhlolwa kokusebenza kwempahla.
Izindinganiso zamazwe ngamazwe ziqinisekisa ukuvumelana komhlaba wonke kanye nokushintshana kwama-blind flange.Noma ngabe kusembonini kawoyela negesi, amakhemikhali, ukuhlinzekwa kwamanzi noma eminye imikhakha yezimboni, la mazinga adlala indima ebalulekile ekuqinisekiseni ukuphepha, ukwethembeka kanye nokusebenza kokuxhunywa kwamapayipi.Ngakho-ke, lapho ukhetha futhi usebenzisa ama-blind flange, kubalulekile ukuqonda nokuhambisana nezindinganiso zamazwe ngamazwe ezisebenzayo ukuze kuqinisekiswe ukusebenza okuzinzile nokuphepha kwesistimu yamapayipi.
