Ọmụmaatụ nke ọkwa nrụgide
Flanges nwere ike iguzogide nrụgide dị iche iche na okpomọkụ dị iche iche. Ka okpomọkụ na-abawanye, ọkwa nrụgide nke flange na-ebelata. Dịka ọmụmaatụ, a na-edepụta flange klaasị 150 na ihe dịka 270 PSIG na ọnọdụ ambient, 180 PSIG na ihe dịka 400 ° F, 150 PSIG na ihe dịka 600 ° F, na 75 PSIG na ihe dịka 800 ° F.
N'ikwu ya n'ụzọ ọzọ, mgbe nrụgide na-agbada, okpomọkụ na-arị elu na nke ọzọ. Ihe ndị ọzọ bụ na flanges nwere ike ịrụ site na ihe dị iche iche, dị ka igwe anaghị agba nchara, nkedo na ductile iron, carbon steel etc .. Ihe ọ bụla nwere ọkwa nrụgide dị iche iche.
N'okpuru ihe atụ nke flangeNPS 12na ọtụtụ klaasị nrụgide. Dị ka ị pụrụ ịhụ, n'ime dayameta na dayameta nke elu elu na niile otu; mana dayameta dị n'èzí, okirikiri bolt na dayameta nke oghere bolt na-ebuwanye ibu na klaasị nrụgide ọ bụla dị elu.
Ọnụọgụ na dayameta (mm) nke oghere bolt bụ:
