Echiche nke ọkwa flange na-amasị nke ọma. Flange klaasị 300 nwere ike ijikwa nrụgide karịa flange klaasị 150, n'ihi na ejiri ọla karịa rụọ flange 300 ma nwee ike idi nrụgide ọzọ. Agbanyeghị, enwere ọtụtụ ihe nwere ike imetụta ikike nrụgide nke flange.

Nhọpụta ọkwa nrụgide

A ga-enye ọkwa nrụgide maka flanges na klaasị.

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.

Ntụle nrụgide-okpomọkụ - Ọmụmaatụ

Ogo nrụgide-okpomọkụ bụ nrụgide gage na-arụ ọrụ kacha mma na nkeji mmanya na okpomoku na ogo Celsius. Maka okpomoku dị n'etiti, a na-anabata interpolation linear. Anaghị anabata njikọta n'etiti aha klaasị.

Ntụle nrụgide-okpomọkụ na-emetụta nkwonkwo flanged nke kwekọrọ na njedebe na bolting na gaskets, nke a na-eme n'usoro dị mma maka nhazi na mgbakọ. Iji akara ndị a maka nkwonkwo flanged anaghị agbaso oke ndị a bụ ọrụ dịịrị onye ọrụ.
