Mbali za Yuantai Derun Longitudinal Dmerged Arc Welded Pipe
1. Njira yopangira
•Kuwotcherera kwamphamvu kwambiri (ERW): koyenera kupanga mapaipi achitsulo ang'onoang'ono ndi apakatikati. Kutentha komwe kumapangidwa ndi mphamvu yamphamvu kumasungunula m'mphepete mwa mzerewo ndikuwuphatikiza pansi pa kupanikizika kuti apange chowotcherera champhamvu.
•Kuwotcherera kwa arc submerged arc (LSAW) komwe kumagwiritsidwa ntchito popanga mapaipi achitsulo akuluakulu, pogwiritsa ntchito ukadaulo wowotcherera wa arc submerged kuti uwotchere mkati ndi kunja nthawi imodzi kuti zitsimikizire kuti chowotchereracho chili bwino.
2. Zipangizo ndi kufotokozera
•Zinthu: Nthawi zambiri amagwiritsa ntchito mitundu yosiyanasiyana ya chitsulo chopangidwa ndi kaboni kapena zinthu zina zachitsulo monga Q195, Q235, Q355, ndi zina zotero. Kusankha kwina kumadalira zofunikira pakugwiritsa ntchito.
•Mafotokozedwe osiyanasiyana: Mafotokozedwe osiyanasiyana a mapaipi achitsulo okhala ndi mainchesi kuyambira ang'onoang'ono mpaka akuluakulu amatha kupangidwa, ndipo makulidwe apadera ndi makulidwe amatha kusinthidwa malinga ndi zosowa za makasitomala.
3. Chithandizo cha pamwamba
•Kupanga ma galvanizing: Kumawonjezera kukana dzimbiri kwa mapaipi achitsulo ndikuwonjezera nthawi yawo yogwirira ntchito.
•Kupaka utoto kapena kuphimba: Kuphimba pamwamba kumachitika malinga ndi zosowa za makasitomala, zomwe sizimangowonjezera mphamvu yolimbana ndi dzimbiri komanso zimakongoletsa mawonekedwe.
4. Kulamulira khalidwe molimba
•Kuyesa zinthu zopangira: Kusanthula kwamphamvu kwa kapangidwe ka mankhwala ndi mayeso a kapangidwe ka makina kumachitika pa gulu lililonse la chitsulo cholowa mufakitale.
•Kuyang'anira njira zopangira: Kukhazikitsa kuyang'anira bwino kwambiri panthawi yonse yopanga, kuphatikizapo kuwunika kulondola kwa miyeso, mtundu wa weld, ndi zina zotero.
•Kuyang'anira zinthu zomwe zamalizidwa: Zinthu zomwe zamalizidwa ziyenera kutsatiridwa ndi njira zingapo zowunikira mozama, monga kuyesa kuthamanga kwa madzi, kuyesa kosawononga, ndi zina zotero, kuti zitsimikizire kuti khalidwe la zinthuzo likukwaniritsa zofunikira.
1.Ntchito zazikulu za mapaipi olumikizidwa molunjika ndi msoko wowongoka
Kuyendera madzimadzi
•Mafuta ndi gasi wachilengedwe: mapaipi otumizira mpweya otsika mphamvu (monga mapaipi a nthambi, mapaipi osonkhanitsira).
•Mapulojekiti osamalira madzi: mapaipi amadzi, njira zotulutsira madzi, mapaipi othirira ulimi.
• Makampani opanga mankhwala: kunyamula zakumwa kapena mpweya wosawononga (zipangizo ziyenera kusankhidwa malinga ndi njira yogwiritsira ntchito).
Uinjiniya wa zomangamanga ndi zomangamanga
•Chimango chomangira: chimagwiritsidwa ntchito popangira mizati, matabwa, ma trusses, ndi zina zotero. pa nyumba zomangira zitsulo.
•Chisanja: chimagwiritsidwa ntchito ngati ndodo yoyima kapena ndodo yopingasa ya chisanja chopepuka, chomwe ndi chosavuta kumanga mwachangu.
•Mipanda ndi zotchingira: monga mapaipi othandizira malo omangira ndi zotchingira msewu.
Kupanga makina
•Malo osungira zida: monga kapangidwe ka chimango cha fani ndi nyumba yoziziritsira mpweya.
•Zida zonyamulira katundu: zinthu zosanyamula katundu wambiri monga ma conveyor rollers ndi ma drive shafts.
Magalimoto ndi mayendedwe
•Chitsa cha magalimoto: zigawo za kapangidwe ka magalimoto ang'onoang'ono ndi mathireyala.
•Malo oyendera: mapaipi othandizira mizati ya nyali za pamsewu ndi mizati ya zizindikiro za magalimoto.
Magawo ena
• Kupanga mipando: zigoba za mipando yachitsulo (monga mashelufu ndi mahema).
•Uinjiniya wamagetsi: manja oteteza chingwe, zida zomangira nsanja yotumizira magiya.
Mafotokozedwe a mitundu ya mapaipi olumikizidwa ndi msoko wowongoka
Mafotokozedwe a mapaipi olumikizidwa molunjika nthawi zambiri amagawidwa ndi mainchesi akunja (OD), makulidwe a khoma (WT), ndi zinthu, ndipo amatsatira miyezo yapadziko lonse lapansi kapena yadziko lonse. Izi ndi magulu odziwika bwino ndi mafotokozedwe wamba:
1. Kugawa m'magulu malinga ndi njira zopangira
Kuwotcherera kwamphamvu kwambiri (chitoliro cha ERW):
•Njira: Gwiritsani ntchito mphamvu yamagetsi yamagetsi yapamwamba kuti mutenthetse m'mphepete mwa mbale yachitsulo ndikuyisungunula pansi pa kupanikizika.
•Mawonekedwe: Chotchingira chopapatiza, chogwira ntchito bwino kwambiri, choyenera mapaipi okhala ndi makoma owonda (makulidwe a khoma ≤ 20mm).
• Ntchito: Kunyamula madzi otsika, chithandizo cha kapangidwe kake.
Kuwotcherera kwa arc m'madzi (Chitoliro cha LSAW, msoko wowongoka wolumikiza arc wozungulira mbali ziwiri):
• Njira: Ukadaulo wothira arc woviikidwa m'madzi umagwiritsidwa ntchito, mbali zonse ziwiri zimathiridwa, ndipo mphamvu ya weld ndi yayikulu.
• Mawonekedwe: Kukhuthala kwa khoma ndi kwakukulu (nthawi zambiri ≥6mm), koyenera pa nthawi ya kupanikizika kwambiri kapena nthawi yodzaza katundu wambiri.
• Kugwiritsa Ntchito: Mapaipi amafuta ndi gasi akutali, mapulojekiti akuluakulu omanga nyumba.
