I-butt-welding flange ingenye ye-flange, ebhekisela ku-flange enentamo ne-round pipe transition futhi ixhunywe nepayipi ngokushisela izinqe. Ngoba ubude bentamo bungahlukaniswaintamo izinqe welding flangefuthiintamo flat welding flange.
Ama-flange we-butt-welding asetshenziswa kakhulu ngoba akulula ukuwohloka, avalwe kahle, asetshenziswa kabanzi, anezidingo ezihambisanayo zokuqina nokunwebeka kanye nenguquko enengqondo ye-butt welding thinning.
Ngokuthuthukiswa kokwakhiwa kwamapayipi amabanga amade, i-flange ene-butt-welded isiyingxenye ebalulekile yokuhlolwa kwengcindezi yamapayipi. Ngaphambi nangemva kokuhlolwa kwengcindezi, ingxenye ngayinye yepayipi idinga ukushanelwa ebholeni, imvamisa yezikhathi ezingama-4-5. Ikakhulukazi ngemva kokuhlolwa kwengcindezi, kunzima ukuhlanza amanzi epayipini, futhi izikhathi zokuhlanza zizokhula.
I-flat welding flange ingolunye uhloboi-flange. Isetshenziswa kabanzi futhi ithuthukiswa embonini yemishini, futhi ithole ukudunyiswa nokuthandwa kubasebenzisi abaningi.
Indawo eyinhloko yesicelo se-flange welding flange ifanelekile, futhi inani elithile lokusebenzisa kanye nokusebenza kwe-flange welding flange kudingeka kunqunywe ngokuvumelana nesimo esithile. Ukukhiqizwa kwe-Flange kuyindleko elula futhi ephansi, kodwa umsebenzi wokushisela mkhulu, ukusetshenziswa kwe-electrode kukhulu, futhi akukwazi ukumelana nokushisa okuphezulu, ukucindezela okukhulu, ukugoba okuphindaphindiwe kanye nokushintshashintsha kwezinga lokushisa. Ngokuvamile isetshenziselwa amapayipi ane-PN ≤ 2.5MPa, izinga lokushisa elivamile, nezinga lokushisa elisebenzayo elingu-t ≤ 0 ℃.
Okunye ukushisela i-weld yangaphandle phakathi kwe-flange nepayipi, kanye nokushisela ipayipi elifakwe ku-flange. Ipayipi kanye nobuso be-flange kufanele bushiselwe ngokuvumelana nezidingo zomhlangano womdwebo. Qaphela ukuthi ubuso be-flange abukwazi ukonakala ngesikhathi sokushisela, ngaphandle kwalokho ukubekwa uphawu akulungile. Indlela yokushisela i-arc welding manual, futhi i-welding edingekayo yinqubo yokushisela ingasetshenziswa.
Inzuzo
I-butt-welding flange inesakhiwo esinengqondo, amandla aphezulu kanye nokuqina, ingakwazi ukumelana nezinga lokushisa eliphezulu nokucindezela okuphezulu, ukugoba okuphindaphindiwe kanye nokuguquguquka kwezinga lokushisa, ukusebenza kahle kokuvala, futhi akulula ukukhubaza. Isebenza kakhulu kumapayipi anengcindezi enkulu noma ukushintshashintsha kwezinga lokushisa noma izinga lokushisa eliphezulu, umfutho ophezulu kanye namapayipi okushisa aphansi. Emindenini, ububanzi bepayipi buncane, futhi ingcindezi ephansi, futhi uxhumano lwe-butt welding flange alubonakali. Egumbini lokubhayela noma indawo yokukhiqiza, kunamapayipi nezinto zokusebenza ezixhunywe ngama-flange welding we-butt yonke indawo.
Iyiphi indlela yokucubungula ye-butt welding flange?
1. Ukubumba okungenalutho ku-square billet, bese kubanda ukugoba kusigaba se-arc, ukudonsa ngemva kokwelashwa kokushisa, bese kuhlanganisana kube yindingilizi yonke ku-lathe eqondile ukuze kucutshungulwe kumumo nosayizi oklanyiwe;
2. Isinyathelo sokuqala ukuthutha ukuya endaweni yokwakha, bese uhlanganisa futhi ushise izingxenye eziningana ze-arc zibe ama-flange welding we-butt;
3. Ama-flange we-butt-welding anamazinga ahlukene okukhiqiza ekusetshenzisweni nasekukhiqizeni, futhi angakhiqizwa futhi asetshenziswe ngokuvumelana nezindinganiso ezihambisanayo, ukuze kubonakale ukubaluleka komsebenzi kanye nokusebenza kwama-flanges akhethekile ekusebenzeni.
