1. Parizvino kune mana flange mwero muChina, ayo ari:
(1) National flange mureza GB/T9112~9124-2000;
(2) Chemical industry flange standard HG20592-20635-1997
(3) Mechanical industry flange standard JB/T74~86.2-1994;
(4) Iyo flange chiyero cheiyo petrochemical indasitiri SH3406-1996
Kutora chiyero chenyika semuenzaniso, tsanangura kusarudzwa kwemaflange.Iyo yenyika standard flange yakakamurwa kuita maviri makuru masisitimu: European system neAmerican system.Mazita ekudzvinyirira eEuropean system flanges anosanganisira: PN0.25, PN0.6, PN1.0, PN1.6, PN2.5, PN4.0, PN6.3, PN10.0, uye PN16.0MPa;Iwo mazita ekumanikidzwa kweAmerican system flanges anosanganisira PN2.0, PN5.0, PN11.0, PN15.0, PN26.0, uye PN42.OMpa.
2. Nheyo yekusarudza flanges
(1) Zvimiro zvesvikiro rekufambisa, zvinosanganisira general medium, special medium, chepfu svikiro, chinopfuta uye chinoputika svikiro;
(2) Zvichienderana nezviyereso zvepakati, kumanikidza kwekushanda, uye tembiricha yekushanda, kana iyo yepakati yakatemwa, iyo inonzi inomanikidza PN yeflange inotemerwa zvichienderana nekupisa kwekushanda uye kudzvanywa kwepakati.
(3) Sarudza nzira yekubatanidza uye yekuisa chisimbiso pamusoro pefomu pakati peflanges nemapombi zvichienderana nenzvimbo yekushandisa uye mamiriro ekubatanidza.
(4) Sarudza zvirevo zveflange zvinoenderana nechinhu chekubatanidza.
