Ama-flange angajwayelekileyilawo axhunywe ezitsheni noma amapayipi nge-fillet welding. Kungaba noma yikuphii-flange. Hlola i-flange ebalulekilenoma i-looper flange ngokuvumelana nobuqotho bendandatho ye-flange nengxenye eqondile.I-Flangeindandatho inezinhlobo ezimbili: intamo nengelona intamo. Uma kuqhathaniswa neintamo isinqe flange, non-standard flangeilula ngesakhiwo futhi ilondoloza impahla, kodwa ukuqina kwayo nokusebenza kokuvala akukuhle njengalokho kwe-neck butt flange.Ama-flange angajwayelekileasetshenziselwa kabanzi ukuxhuma imikhumbi namapayipi anengcindezi ephakathi nendawo nephansi.
I-flange engajwayelekileilungele izinga lomfutho ophansi, ukuguquguquka kwengcindezi, ukudlidliza kanye nomthelela akulona uhlelo lwamapayipi olubi kakhulu.Ama-flange angajwayelekileasetshenziswa kakhulu ngoba kulula ukuwaqondanisa ngesikhathi sokushisela nokuhlanganisa futhi angabizi kakhulu.

Ama-flange angajwayelekileyizindandatho ezenziwe ngezinto ezingakhiqiza ukuguqulwa kwepulasitiki futhi zibe namandla athile. Ama-gaskets amaningi asikwa kumashidi angewona awensimbi noma akhiqizwa ngokulingana yifektri yochwepheshe. Ingabe ibhodi lerabha le-asbestos, ibhodi le-asbestos, ibhodi le-polyethylene nokunye. Futhi i-gasket yokugcwalisa insimbi eyenziwe nge-asbestos nezinye izinto ezingezona ezensimbi ezisongwe ngepuleti elincane lensimbi (ishidi lensimbi, insimbi engagqwali); Olunye uhlobo lwe-gasket lwenziwe nge-tape yensimbi encane kanye ne-asbestos tape eboshwe ndawonye. I-gasket yenjoloba evamile ifaneleka lapho izinga lokushisa lingaphansi kuka-120 ℃; I-Rubber gasket ifanele izinga lokushisa elingaphansi kuka-450 ℃, izinga lokushisa likawoyela lingaphansi kuka-350 ℃, izikhathi zengcindezi ephansi. Esimeni se-5MPa ngezansi, ipuleti le-asbestos elimelana ne-asidi ngokuvamile lisetshenziselwa ukugqwala okuphakathi.
Emishinini yokucindezela okukhulu namapayipi, ama-gaskets ensimbi ohlobo lwe-lens noma ezinye izimo ezenziwe ngethusi, i-aluminium, insimbi eyi-10 nensimbi engagqwali isetshenziswa. I-gasket ye-flange engeyona ejwayelekile kanye nobubanzi bokuxhumana obuvaliwe buncane kakhulu (ukuxhumana komugqa), ubuso bokuvala kanye neziqu zokuqeda ukucubungula i-gasket ziphezulu.
Ngaphezu kwalokho,ama-flange angajwayelekileingavimbela ukugqwala nokuqhekeka kwendawo. Ngokuvamile indawo ye-flange engeyona evamile izofakwa ugesi (i-zinc ephuzi, i-zinc emhlophe, njll.), noma igcotshwe ngamafutha e-anti-rust, fafaza ngopende ovimbela ukugqwala.
