FLANGE NDI CHIYANI?KODI MITUNDU YA FLANGE NDI CHIYANI?

Flange ndi mphepete kapena m'mphepete mwa chitoliro, valavu, kapena chinthu china, chomwe chimagwiritsidwa ntchito kuonjezera mphamvu kapena kuthandizira kulumikiza mapaipi kapena zopangira.

Flange amadziwikanso kuti flange convex disk kapena mbale ya convex. Ndi zigawo zooneka ngati disk, zomwe zimagwiritsidwa ntchito pawiri. Zimagwiritsidwa ntchito makamaka pakati pa chitoliro ndi valavu, pakati pa chitoliro ndi chitoliro ndi pakati pa chitoliro ndi zipangizo, etc. Ndizigawo zomwe zimagwirizanitsa ndi kusindikiza. Pali ntchito zambiri pakati pa zidazi ndi mapaipi, kotero ndege ziwirizi zimagwirizanitsidwa ndi mabawuti, ndipo mbali zolumikizira ndi kusindikiza zimatchedwa flange.

Flanges amagwiritsidwa ntchito popanga mapaipi kulumikiza mapaipi, ma valve, mapampu, ndi zida zina. Amapereka njira zolumikizirana mosavuta ndi kuphatikizira zigawo, komanso kuyang'anira, kusinthidwa, kapena kuyeretsa dongosolo.

Nthawi zambiri, pa flange pali mabowo ozungulira kuti agwire ntchito yokhazikika. Mwachitsanzo, mukamagwiritsa ntchito polumikizira chitoliro, mphete yosindikizira imawonjezeredwa pakati pa mbale ziwiri za flange. Ndiyeno kugwirizanako kumangiriridwa ndi mabawuti. Flange yokhala ndi zovuta zosiyanasiyana imakhala ndi makulidwe osiyanasiyana komanso ma bolts osiyanasiyana. Zida zazikulu zomwe zimagwiritsidwa ntchito pa flange ndi chitsulo cha carbon, chitsulo chosapanga dzimbiri ndi chitsulo cha alloy, etc.

Pali mitundu ingapo yaflanges, chilichonse chinapangidwa ndi zolinga zake. Nayi mitundu yodziwika bwino ya flanges:

1. Weld Neck Flange (WN):Mtundu uwu wa flange umadziwika ndi khosi lalitali, lopindika lomwe limalumikizidwa ku chitoliro. Zapangidwa kuti zisamutse kupsinjika kuchokera ku flange kupita ku chitoliro, kuchepetsa chiopsezo cha kutayikira.Weld khosi flangesNthawi zambiri amagwiritsidwa ntchito pazida zamphamvu komanso zotentha kwambiri.
2. Slip-On Flange (SO): Slip-on flangesali ndi m'mimba mwake wokulirapo pang'ono kuposa chitoliro, ndipo amazembera papaipi kenako amawotcherera m'malo mwake. Ndizosavuta kugwirizanitsa ndipo ndizoyenera kugwiritsira ntchito zochepetsera zochepa. Palinso mtundu wina wa flange wofanana nawo, wotchedwa plate flange. Kusiyanitsa pakati pa awiriwa kumakhala kukhalapo kapena kusakhalapo kwa khosi, zomwe ziyenera kusiyanitsa mosamalitsa.
3. Blind Flange (BL): Akhungu flangesndi ma disks olimba omwe amagwiritsidwa ntchito kutsekereza chitoliro kapena kuyimitsidwa kumapeto kwa payipi. Alibe dzenje lapakati ndipo amagwiritsidwa ntchito kusindikiza kumapeto kwa mapaipi.
4. Socket Weld Flange (SW): Socket weld flangeskhalani ndi socket kapena mapeto achikazi omwe amagwiritsidwa ntchito polandira chitoliro. Chitolirocho chimalowetsedwa mu socket ndiyeno welded m'malo mwake. Amagwiritsidwa ntchito popanga mapaipi ang'onoang'ono komanso kukakamiza kwambiri.
5. Flange Yopangidwa ndi Ulusi (TH): Ma flanges a ulusiali ndi ulusi pamwamba, ndipo amagwiritsidwa ntchito ndi mapaipi omwe ali ndi ulusi wakunja. Iwo ndi oyenerera ntchito zochepetsera zochepa.
6. Lap Joint Flange (LJ): Mitundu ya flangesamagwiritsidwa ntchito ndi nthiti kapena mphete yolumikizira pachiuno. Flange imasunthidwa momasuka pa chitoliro ndiyeno kumapeto kwa chishango kapena mphete yolumikizirana ndikumangirira ku chitoliro. Mtundu uwu wa flange umalola kugwirizanitsa mosavuta mabowo a bolt.
