Kufanana ndi kusiyana pakati pa nangula flanges ndi welded khosi flanges

Welded neck flange, yomwe imadziwikanso kuti high khosi flange, ndi wautali komanso wokhotakhota khosi lalitali kuchokera pamalo owotcherera pakati pa flange ndi chitoliro kupita ku mbale ya flange. Makulidwe a khoma la khosi lalitali pang'onopang'ono amasintha kupita ku makulidwe a khoma la chitoliro motsatira njira ya kutalika, kuwongolera kutha kwa kupsinjika ndikuwonjezera mphamvu ya flange.Welded khosi flangesamagwiritsidwa ntchito makamaka pamene mikhalidwe yomanga imakhala yovuta, monga momwe flange imakhala ndi kupsinjika kwakukulu kapena kusinthasintha mobwerezabwereza chifukwa cha kuwonjezereka kwapaipi kapena katundu wina; Kapenanso, atha kukhala mapaipi omwe ali ndi kusinthasintha kwakukulu kwa kuthamanga ndi kutentha, kapena mapaipi okhala ndi kutentha kwambiri, kuthamanga kwambiri, ndi kutentha kwa zero.

Ubwino wa awelded khosi flangendizoti sichimapunduka mosavuta, chili ndi chisindikizo chabwino, ndipo chimagwiritsidwa ntchito kwambiri. Iwo ali lolingana rigidity ndi elasticity zofunika ndi wololera kuwotcherera kupatulira kusintha. Mtunda pakati pa kuwotcherera mphambano ndi pamwamba olowa ndi waukulu, ndipo olowa pamwamba alibe kuwotcherera kutentha mapindikidwe. Imatengera mawonekedwe owoneka bwino a belu, oyenera mapaipi okhala ndi kupanikizika kwakukulu kapena kusinthasintha kwa kutentha kapena mapaipi okhala ndi kutentha kwakukulu, kokwera, ndi kotsika. Amagwiritsidwa ntchito polumikiza mapaipi ndi mavavu okhala ndi PN wamkulu kuposa 2.5MPa; Itha kugwiritsidwanso ntchito pamapaipi omwe amanyamula zinthu zodula, zoyaka moto komanso zophulika.

Anchor flange, monga thupi lozungulira la axisymmetric lomwe lili ndi flange, lili ndi makosi osakanikirana kumbali zonse za flange. Imaphatikiza ma flange awiri owotcherera omwe amawoneka ngati olumikizidwa palimodzi, amachotsa ma gaskets osindikizira, ndipo amapangidwa kukhala chitsulo chophatikizika chachitsulo. Imalumikizidwa ndi mapaipi amafuta ndi gasi kudzera pakuwotcherera, ndipo imayikidwa ndi milu ya nangula ndi thupi lake la flange ndi flange, lomwe lingagwiritsidwe ntchito kulumikiza mapaipi okhazikika ndipo ndi oyenera kulumikizidwa kokhazikika kwa masiteshoni ambiri, zipinda zama valve.

Anchor flange ndi chinthu chaumisiri chomwe chitha kusinthidwa ndi mapaipi afupiafupi okhala ndi mphete zopondereza kapena manja apakhoma m'malo omwe ali ndi mphamvu yochepa. Pakulumikiza mapaipi okhazikika omwe amafunikira kuikidwa m'manda mobisa kapena kukonzanso moyo wonse, ndipo kupanikizika kuli kwakukulu, ma flanges ochiritsira amagwiritsidwa ntchito, omwe sangathe kuonetsetsa kuti mapaipi othamanga kwambiri ndi otetezeka komanso odalirika.
