1. Yanayin ƙira da matsa lamba na akwati;

2. Matsayin haɗin kai don bawuloli, kayan aiki, zazzabi, matsa lamba, da matakan matakan da aka haɗa da shi;

3. Tasirin damuwa na thermal akan flange na bututu mai haɗawa a cikin bututun sarrafawa (high-zazzabi, bututun thermal);

4. Tsari da halayen matsakaicin aiki:

Don kwantena a ƙarƙashin yanayin injin, lokacin da injin injin ya kasa 600mmHg, ƙimar matsi na flange mai haɗawa bai kamata ya zama ƙasa da 0.6Mpa ba; Lokacin da injin digiri ne (600mmHg ~ 759mmHg), da matsa lamba matakin na a haɗa flange kada ya zama kasa da 1.0MPa;

Don kwantenan da ke ɗauke da fashewar kafofin watsa labarai masu haɗari da matsakaici masu haɗari masu haɗari, matakin matsa lamba na ƙima na flange ɗin kwantena bai kamata ya zama ƙasa da 1.6MPa ba;

Don kwantenan da ke ɗauke da kafofin watsa labarai masu haɗari sosai kuma masu guba, da kuma kafofin watsa labarai masu iya jurewa, ƙimar matsa lamba na madaidaicin flange ɗin ganga bai kamata ya zama ƙasa da 2.0MPa ba.

Ya kamata a lura da cewa a lokacin da sealing surface na haši flange na akwati da aka zaba a matsayin concave convex ko tenon tsagi surface, da connecting bututu located a saman da gefen ganga ya kamata a zaba a matsayin concave ko tsagi surface flanges; Bututun haɗin da ke ƙasan akwati ya kamata ya yi amfani da flange mai ɗagawa ko ɗagawa.
