Flange, makwaara dị ka flange ma ọ bụ flange.Flange bụ ihe na-ejikọta ogwe aka ma jiri ya mee ihe maka ijikọ ọnụ ọnụ ọkpọkọ;Ọ bara uru bụ flanges na ntinye na ntinye nke akụrụngwa, ejiri maka ijikọ ngwaọrụ abụọ, dị ka flanges gearbox.Njikọ flange ma ọ bụ nkwonkwo flange na-ezo aka na njikọ nwere ike ịpụpụ site na ngwakọta nke flanges, gaskets, na bolts jikọtara ọnụ dị ka nhazi akara.Pipeline flange na-ezo aka flange eji maka ọkpọkọ na pipeline akụrụngwa, na mgbe eji na akụrụngwa, ọ na-ezo aka mbata na mpụta flanges nke akụrụngwa.Dị ka ọkwa nrụgide dị iche iche nke valves si dị, a na-ahazi flanges nwere ọkwa nrụgide dị iche iche na flanges pipeline.N'akụkụ a, ndị injinia German sitere na Ward WODE na-ewebata ọkwa nrụgide flange dị iche iche dịka ụkpụrụ mba ụwa si dị:

Dị ka ASME B16.5 si kwuo, flanges ígwè nwere 7 nrụgide ratings: Class150-300-400-600-900-1500-2500 (dabara mba ọkọlọtọ flanges nwere PN0.6, PN1.0, PN1.6, PN2.5, PN4). .0, PN6.4, PN10, PN16, PN25, PN32Mpa ratings)

Ogo nrụgide nke flange doro anya.Flanges klaasị 300 nwere ike iguzogide nrụgide dị ukwuu karịa klaasị 150 n'ihi na klaasị 300 kwesịrị ka ejiri ihe ndị ọzọ na-eguzogide nrụgide dị ukwuu.Agbanyeghị, ikike mkpakọ nke flanges na-emetụta ọtụtụ ihe.A na-egosipụta ọkwa nrụgide nke flange na paụnd, ma enwere ụzọ dị iche iche iji gosipụta ọkwa nrụgide.Dịka ọmụmaatụ, nkọwa 150Lb, 150Lbs, 150 # na Class150 bụ otu ihe ahụ.
