Kiwango cha Flange:

Kiwango cha kitaifa GB/T9115-2000, Wizara ya Mashine STANDARD JB82-94, Wizara ya Sekta ya Kemikali kiwango HG20595-97HG20617-97, Wizara ya Umeme kiwango GD0508 ~ 0509, American standard ASME/ANSI B16.5, Japan kiwango JIS/KS (5K, 10K, 16K, 20K), kiwango cha Ujerumani DIN.

Flangesinaweza kugawanywa katika aina mbalimbali:
1. Kulingana na hali ya usindikaji, kulingana na nyenzo za bidhaa, kulingana na kiwango cha uzalishaji, kulingana na hali ya uunganisho, kulingana na vipimo vya bidhaa, nk. Hali maalum uainishaji maalum.
2. Nyenzo za flange: 20#, A105, Q235A, 12Cr1MoV, 16MnR, 15CrMo, 18-8, 321, 304, 304L, 316, 316L, nk.
