1. Flange yowotcherera ya mbale
Flange yolumikizira mbale ya PL imatanthauza flange yomwe imalumikizidwa ku payipi pogwiritsa ntchito ma fillet welds. Flange yolumikizira mbale ya PL ndi flange yosasinthika ndipo imafanana ndi
ubwino:
Zipangizo zosavuta kupeza, zosavuta kupanga, zotsika mtengo komanso zogwiritsidwa ntchito kwambiri
kusowa:
Ili ndi kulimba kosalimba, kotero siyenera kugwiritsidwa ntchito m'mapayipi opangira mankhwala omwe ali ndi zinthu zomwe zimafunika, zomwe zimayaka moto, zimaphulika komanso zimakhala ndi vacuum yambiri komanso m'malo oopsa kwambiri. Mitundu ya malo otsekera ndi malo athyathyathya komanso okwezeka.
2. Flange yowotcherera yathyathyathya yokhala ndi khosi
Flange yolumikizira khosi ndi ya dongosolo la dziko lonse la flange. Ndi chimodzi mwa zizindikiro za flange ya dziko lonse (yomwe imatchedwanso GB flange) ndipo ndi imodzi mwa flange zomwe zimagwiritsidwa ntchito kwambiri pazida kapena mapaipi.
ubwino:
Kuyika pamalopo ndikosavuta, ndipo njira yopukutira ndi kupukuta ma welds ikhoza kuchotsedwa.
kusowa:
Kutalika kwa khosi la flange yolumikizidwa bwino yokhala ndi khosi ndi kotsika, zomwe zimapangitsa kuti flange ikhale yolimba komanso yonyamula katundu. Poyerekeza ndi ma flange olumikizira matako, ntchito yolumikizira ndi yayikulu, kugwiritsa ntchito ndodo yolumikizira ndi kwakukulu, ndipo singathe kupirira kutentha kwambiri ndi kupanikizika, kupindika mobwerezabwereza komanso kusinthasintha kwa kutentha.
3. Flange yowotcherera matako yokhala ndi khosi
Mitundu yotsekera pamwamba pa flange yolumikizira matako a khosi ndi iyi: Malo okwezeka (RF), malo opindika (FM), malo opindika (M), malo a tenon (T), malo otsetsereka (G), malo ozungulira (FF).
ubwino:
Kulumikizana sikophweka kusokoneza, kutseka kwake ndi kwabwino, ndipo kumagwiritsidwa ntchito kwambiri. Ndikoyenera mapaipi okhala ndi kutentha kwakukulu kapena kupanikizika kapena mapaipi okhala ndi kutentha kwakukulu, kupanikizika kwakukulu komanso kutentha kochepa. Amagwiritsidwanso ntchito pa mapaipi onyamula zinthu zodula, zinthu zoyaka moto ndi zophulika, komanso mpweya woipa.
kusowa:
Flange yolumikizira matako ndi yokulirapo, yolemera, yokwera mtengo, komanso yovuta kuyiyika ndi kuyiyika pamalo ake. Chifukwa chake, nthawi zambiri imagundidwa panthawi yoyendetsa.
4. Flange yophatikizana
Flange yolumikizirana ndi njira yolumikizira flange. Ndi mtundu wa flange yachitsulo yolumikizidwa ndi khosi. Zipangizo zimaphatikizapo chitsulo cha kaboni, chitsulo chosapanga dzimbiri, chitsulo cha alloy, ndi zina zotero. Pakati pa miyezo yosiyanasiyana yapakhomo, IF imagwiritsidwa ntchito kuyimira flange yolumikizirana. Imagwiritsidwa ntchito kwambiri m'mapaipi okhala ndi kuthamanga kwambiri. Njira yopangira nthawi zambiri imakhala yopangira.
5. Flange yowotcherera ya soketi
Flange yolumikizira soketi ndi flange yokhala ndi mbali imodzi yolumikizidwa ku chitoliro chachitsulo ndipo mbali inayo yolumikizidwa ndi mabolts.
ubwino:
Palibe cholumikizira chokonzedwa kale chomwe chikufunika pa chitoliro cholumikizidwa ndi cholumikizira mapaipi cholumikizidwa ndi socket welded; Chifukwa zolumikizira zolumikizidwa ndi socket welded zidzakhalanso ndi ntchito yolinganiza, palibe chifukwa cholumikizira malo owongolera panthawi yolumikizira; Zolumikizira zolumikizidwa ndi socket welded zikalumikizidwa, zinthu zolumikizira sizidzalowa mu chitoliro.
kusowa:
Owotcherera ayenera kuonetsetsa kuti kusiyana kwa kukula pakati pa phewa la soketi ndi chitoliro ndi 1.6mm. Ming'alu yamkati ndi mipata yokulira mu dongosolo la soketi yowotcherera ingathe kuyambitsa dzimbiri. Ichi ndichifukwa chake amaonedwa kuti ndi osayenerera kugwiritsidwa ntchito ndi ma radioactive kapena corrosive.
6. Flange yolumikizidwa
Flange yolumikizidwa ndi flange yosalumikizidwa yomwe imasuntha dzenje lamkati la flange kukhala ulusi wa mapaipi ndikulilumikiza ndi mapaipi olumikizidwa. (Nkhani ya anthu onse: Pump Butler)
ubwino:
Poyerekeza ndi ma flange opindika kapena ma butt welding flange, ma flange opindika ndi osavuta kuyika ndi kusamalira, ndipo angagwiritsidwe ntchito pa mapaipi ena komwe kupindika sikuloledwa pamalopo. Ma alloy steel flanges ali ndi mphamvu zokwanira, koma si osavuta kupindika, kapena ali ndi magwiridwe antchito oipa. Ma flange opindika amathanso kusankhidwa.
kusowa:
Ndikoyenera kuti musagwiritse ntchito ma flange okhala ndi ulusi kuti mupewe kutuluka kwa madzi pamene kutentha kwa chitoliro kukusintha mofulumira kapena pamene kutentha kuli pamwamba pa 260°C ndi pansi pa -45°C.
7. Mphete yowotcherera matako yotayirira
Flange yolumikizira mphete yolumikizira matako ndi chidutswa cha flange chosunthika, chomwe nthawi zambiri chimagwirizana ndi madzi ndi zolumikizira zotulutsira madzi. Wopanga akachoka ku fakitale, pamakhala flange kumapeto onse awiri a cholumikizira chokulitsa, chomwe chimalumikizidwa mwachindunji ndi mapaipi ndi zida zomwe zili mu projekitiyi ndi mabolts.
ubwino:
sungani ndalama. Ngati chitoliro chili chapadera komanso chokwera mtengo, mtengo wa ma flange olumikizira a chinthu chomwecho umakhala wokwera. Zosavuta kupanga. Mwachitsanzo, zimakhala zovuta kulumikiza mabowo a flange polumikiza kapena kuletsa mabowo a flange kusintha posintha zida mtsogolo.
kusowa:
Kupirira kupsinjika kochepa. Sikophweka kulumikiza kapena kukonza kapena kumafuna mphamvu zambiri. Monga mapaipi apulasitiki, mapaipi a fiberglass, ndi zina zotero. Mphamvu ya mphete yolumikizira ndi yochepa (makamaka pamene makulidwe ake ndi ochepera 3mm)
8. Flange yolumikizira mphete yosalala yotayirira
Flange yosalala ya mphete yopyapyala ndi chidutswa cha flange chosunthika. Lumikizani mwachindunji ndi mapaipi ndi zida zomwe zili mu projekitiyi ndi mabolts. Cholinga chogwiritsa ntchito flange yosalala ya mphete yopyapyala nthawi zambiri chimakhala kusunga zinthu. Kapangidwe kake kamagawidwa m'magawo awiri. Malekezero amodzi a gawo la chitoliro amalumikizidwa ndi chitoliro, malekezero ena amapangidwa kukhala flange, ndipo gawo la flange limayikidwa pa flange.
ubwino:
Yosavuta kuwotcherera kapena kukonza kapena yofunikira mphamvu zambiri, monga mapaipi apulasitiki, mapaipi a fiberglass, ndi zina zotero. Ndi yosavuta kumanga. Mwachitsanzo, mabowo ofanana ndi a flange bolt amapangitsa kuti zikhale zosavuta kulumikiza polumikiza kapena kuletsa mabowo a flange bolt kusintha posintha zida mtsogolo. Mitengo ikakhala yokwera, sungani ndalama. Ngati chitoliro chili chapadera, mtengo wa ma flange olumikizira a chinthu chomwecho umakhala wokwera.
kusowa:
Vomerezani kuti kupsinjika kuli kochepa. Mphamvu ya mphete yolumikizira ndi yochepa (makamaka pamene makulidwe ake ndi ochepera 3mm)
