The neck butt welding flange, yomwe imadziwikanso kuti high khosi flange, ndi yayitali komanso yokhotakhota khosi lalitali kuchokera pamalo owotcherera pakati pa flange ndi chitoliro kupita ku mbale ya flange.Makulidwe a khoma la gawo ili la khosi lalitali pang'onopang'ono amapita ku makulidwe a khoma la chitoliro motsatira njira ya kutalika, zomwe zimapangitsa kuti kusokonezeka kwapang'onopang'ono kuwonjezere mphamvu ya flange.The neck butt-welding flange imagwiritsidwa ntchito makamaka nthawi zomwe zimagwira ntchito ndizovuta kwambiri, monga nthawi yomwe kupanikizika kwapakatiflangendi lalikulu kapena kupsinjika maganizo kumasintha mobwerezabwereza chifukwa cha kuwonjezereka kwa payipi kapena katundu wina;Mipope yokhala ndi kusinthasintha kwakukulu kwa kuthamanga ndi kutentha kapena mapaipi okhala ndi kutentha kwakukulu, kuthamanga kwambiri ndi kutentha kochepa pansi pa ziro.

Thekhosi matako-kuwotcherera flangesichophweka kupunduka, chili ndi chisindikizo chabwino, ndipo chimagwiritsidwa ntchito kwambiri.Iwo ali lolingana rigidity ndi elasticity zofunika ndi wololera matako kuwotcherera kupatulira kusintha.Mtunda pakati pa welded mphambano ndi pamwamba olowa ndi lalikulu, ndipo olowa pamwamba alibe kuwotcherera kutentha mapindikidwe.Iwo utenga ndi zovuta kwambiri lipenga mawonekedwe, amene ali oyenera mapaipi ndi kuthamanga lalikulu kapena kusinthasintha kutentha kapena kutentha, kuthamanga ndi otsika mapaipi kutentha.Amagwiritsidwa ntchito polumikiza mapaipi ndi mavavu okhala ndi PN wamkulu kuposa 2.5 MPa;Amagwiritsidwanso ntchito m'mapaipi otumizira zinthu zodula, zoyaka moto komanso zophulika.

Njira Masitepe

Njira yowotcherera pakhosi nthawi zambiri imapangidwa ndi kuponyedwa kolondola kwa centrifugal flange.Poyerekeza ndi kuponyedwa kwa mchenga wamba, mawonekedwe amtundu uwu wa kuponyera ndiabwinoko ndipo mtundu wake umakhala wabwino kwambiri.

Choyamba, tiyenera kupanga njira ya centrifugal flange, ndondomeko njira ndi mankhwala centrifugal kuponyera kupangakhosi matako kuwotcherera flange.The neck butt welding flange product imakonzedwa motsatira njira izi:

① Ikani zitsulo zosaphika mung'anjo yamagetsi yapakatikati kuti musungunuke kuti kutentha kwachitsulo chosungunuka kufika 1600-1700 ℃;

② Yatsani nkhungu yachitsulo ku 800-900 ℃ ndikusunga kutentha kosalekeza;

③ Yambitsani centrifuge ndikutsanulira chitsulo chosungunuka mu sitepe ① mu nkhungu preheating mu sitepe ②;

④ Kuponyera kudzakhazikika mwachibadwa mpaka 800-900 ℃ ndikusungidwa kwa mphindi 1-10;

⑤ Kuziziritsa ndi madzi kutseka kutentha kwabwinobwino, tsitsani ndikutulutsa kuponya
