Zofanana ndi kusiyana pakati pa kuwotcherera khosi flanges ndi hubbed slip pa flanges.

Kuwotcherera khosi flangendikutsika pa flangendi awiri ofananakugwirizana kwa flangenjira, zomwe zimakhala ndi zofanana komanso zosiyana pakupanga ndi kugwiritsa ntchito.

Zofanana

1. Mapangidwe a khosi:

Onsewa ali ndi khosi la flange, lomwe ndi gawo lotuluka lomwe limagwiritsidwa ntchito kulumikiza mapaipi, omwe nthawi zambiri amalumikizidwa ndi mabawuti.

2. Kulumikizana kwa Flange:

Ma flanges onse amalumikizidwa palimodzi pogwiritsa ntchito mabawuti kuti apange kulumikizana kolimba kwa mapaipi.

3. Zipangizo zothandizira:

Zida zofanana zingagwiritsidwe ntchito popanga, monga zitsulo za carbon, zitsulo zosapanga dzimbiri, zitsulo za aloyi, ndi zina zotero, kuti zigwirizane ndi malo osiyanasiyana ogwira ntchito.

4. Cholinga:

Itha kugwiritsidwa ntchito kulumikiza mapaipi, zotengera, ndi zida, kukwaniritsa kulumikizana ndi kusindikiza kwamapaipi.

Kusiyana

1. Maonekedwe a khosi:

Neck kuwotcherera flange: Khosi lake nthawi zambiri limakhala lalitali, lopindika kapena lotsetsereka, ndipo gawo lowotcherera lomwe limalumikiza payipi ndi lalifupi.
Flat kuwotcherera flange ndi khosi: Khosi lake ndi lalifupi, mbali yowotcherera ndi yayitali, ndipo ndi yowongoka kapena yopindika pang'ono.

2. Njira yowotcherera:

Neck kuwotcherera flange: Nthawi zambiri kugwiritsa ntchito njira kuwotcherera matako, pamwamba mawonekedwe a flange khosi welded ku payipi ndi conical, kuti weld bwino ndi payipi.
Flange yowotcherera yokhala ndi khosi: Nthawi zambiri, kuwotcherera kwathyathyathya kumagwiritsidwa ntchito, ndipo mawonekedwe amtundu wa khosi la flange wowotcherera ku payipi amakhala owongoka.

3. Zochitika:

Neck welded flange: yoyenera kuthamanga kwambiri, kutentha kwambiri, ndi malo ogwedezeka kwambiri, kupereka mphamvu zabwinoko ndi kusindikiza.
Khosi lathyathyathya kuwotcherera flange: Nthawi zambiri ntchito otsika ndi sing'anga kuthamanga, otsika ndi sing'anga kutentha ndi zofunika zochepa okhwima.

4. Miyezo:

Neck welded flange: Imagwirizana ndi miyezo monga ANSI (American National Standards Institute) kapena DIN (German Industrial Standards).
Flat kuwotcherera flange ndi khosi: Ikhozanso kukumana ndi miyezo yofananira, koma nthawi zambiri imakhala yoyenera machitidwe omwe ali ndi mphamvu zochepa komanso kutentha.

Ponseponse, kusankha kwa mtundu wa flange woti mugwiritse ntchito kuyenera kutsimikiziridwa malinga ndi zofunikira zaumisiri, kupanikizika, kutentha, ndi chilengedwe. Ma flanges owotcherera khosi nthawi zambiri amagwiritsidwa ntchito movutikira, pomwe zowotcherera zokhala ndi khosi ndizoyenera uinjiniya wamba.
