Njira Zosiyanasiyana Zolumikizira Mapaipi a Ceramic Osatha Kutha

1: Kulumikiza kwa kuwotcherera

 Kulumikiza ndi kuwotcherera ndi njira yolumikizira yomwe imagwiritsidwa ntchito kwambiri m'mapaipi a ceramic omwe satha kutha. Masitepe enieni ndi awa:

 1). Kuwotcherera kwa malo: Choyamba, kuwotcherera malo pakhoma lamkati la chitoliro. Malo awa amagwiritsidwa ntchito kukonza mapepala kapena zingwe zadothi zosatha. Kuwotcherera kwa malowa kumagwiritsa ntchito ukadaulo wobisika wowotcherera kuti utsimikizire kukhazikika ndi kukongola kwa kulumikizana.

 2). Kukhazikitsa pepala la ceramic: Kenako, ikani pepala la ceramic losatha kusweka looneka ngati arc kapena mzere wokhala ndi mipata m'mipata. Pofuna kutsimikizira ubwino wa kulumikizana, chomangira chofewa choyamwa (monga chomangira cha ceramic, chomwe chiyenera kupirira kutentha kwa ≥350°C) nthawi zambiri chimagwiritsidwa ntchito pakati pa ceramic ndi khoma lamkati kuti chidzaze, chomwe chimatha kuyamwa mafunde ogwedezeka ndikuchita gawo lachiwiri lolumikizira.

 3). Kulimba kwa welding: Mukalumikiza mipata ku chitoliro, chisamaliro chiyenera kuperekedwa ku kulimba kwa welding. Mwachitsanzo, mukalumikiza ndi zitsulo, kuchuluka kwa malo olumikizira mkati mwa 100mm nthawi zambiri kumakhala kokulirapo kuposa ma point 4, ndipo njira yolumikizira nthawi zambiri imagwiritsa ntchito welding ya argon arc kuti itsimikizire kulimba kwa welding ndikuchepetsa kumasuka ndi kugwa komwe kumachitika chifukwa cha kugwedezeka kwa makina ndi zifukwa zina.

 Ubwino wa kulumikizana ndi welding ndi wakuti kulumikizanako ndi kolimba, kumatha kupirira kupsinjika kwakukulu ndi kugundana, ndipo ndikoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana zovuta.

2. Kulumikizana kwa Flange

Kuwonjezera pa kulumikiza zolumikizira, mapaipi a ceramic osatha ntchito amathanso kulumikizidwa ndikuyikidwa kudzera mu ma flange. Nkhani zotsatirazi ziyenera kukumbukiridwa pokhazikitsa kulumikiza kwa flange:

 1). Chogwirira mosamala: Mapaipi a ceramic osatha kutha ayenera kusamalidwa mosamala panthawi yonyamula ndi kuyika kuti apewe kugundana mwamphamvu ndi zinthu zolimba zomwe zingagunde mbali ya ceramic kuti apewe kuwonongeka mbali ya kumapeto.

2). Kuyika mapaipi opangidwa ndi ceramic molondola: Mukayika mapaipi a ceramic, mzere wapakati wa chitoliro uyenera kulumikizidwa ndi mzere wapakati wa chitoliro kuti ulumikizidwe kuti zitsimikizire kuti malekezero awiri aikidwa bwino ndipo kusalingana kwa nkhope kumapeto kuyenera kulamulidwa mkati mwa mtunda winawake (monga mkati mwa 1 mm).

3). Kukhazikitsa njira: Njira yopangira ceramic mkati ndi njira yokonzera chubu cha ceramic chosawonongeka zimatsimikizira momwe chikuyendera. Pakukhazikitsa, madzi operekedwa ndi kusiyana kolumikizira ziyenera kukhala mbali imodzi malinga ndi zofunikira zaukadaulo kuti zichepetse kupukuta ndi kuwonongeka kwa mapaipi.

4). Yang'anani kutseka: Pa mapaipi a ceramic osatha omwe amanyamula madzi monga ufa, mpweya ndi zakumwa, kutseka kwa cholumikiziracho kuyenera kuyang'aniridwa mosamala panthawi yoyika kuti madzi asatuluke.

3. Njira zina zolumikizirana

 Kuwonjezera pa njira ziwiri zazikulu zolumikizira zomwe zili pamwambapa, palinso njira zina zolumikizira mapaipi a ceramic osatha, monga:

 Kulumikiza ma patch: Gwiritsani ntchito mapepala a ceramic kapena zingwe za ceramic kuti muzimangirire mwachindunji mu chitoliro. Njira yolumikizira iyi ndi yovuta kwambiri kupanga, imafuna ukadaulo waukadaulo, ndipo ili ndi zofunikira zapamwamba pa zomatira.

Kulumikizana kwa Hybrid: Nthawi zina zapadera, njira yolumikizira yosakanikirana yophatikiza kuwotcherera ndi kuphatikizika ingagwiritsidwe ntchito kukwaniritsa zofunikira zinazake zogwiritsidwa ntchito.

 Kawirikawiri, pali njira zambiri zolumikizira mapaipi a ceramic osatha, ndipo njira yeniyeni yosankhidwa iyenera kutsimikiziridwa malinga ndi momwe amagwiritsidwira ntchito komanso malo ogwirira ntchito. Panthawi yolumikizira, njira zoyenera zogwirira ntchito ndi zofunikira zaukadaulo ziyenera kutsatiridwa mosamala kuti zitsimikizire kuti kulumikizana kuli bwino komanso nthawi yayitali.
