Longitudinal Welded Njira ndi Zopindulitsa Makhalidwe
ERW ndi LSAW welded steel mapaipi ndi njira zowotcherera zamtali zazitali ndipo zimagwiritsidwa ntchito kwambiri.
ERW (Electric Resistance Welding)
Kugwiritsa ntchito: Amagwiritsidwa ntchito kwambiri popanga machubu ang'onoang'ono mpaka apakatikati, okhala ndi mipanda yopyapyala, machubu achitsulo otalikirapo.
Makhalidwe: Kusungunuka kwa zinthu zolumikizana ndi kutentha kosasunthika, kutentha ndi kukanikiza m'mphepete mwachitsulo pogwiritsa ntchito mafunde othamanga kwambiri.
Ubwino wake: Zotsika mtengo, zofulumira kupanga, zoyenera kupanga voliyumu yayikulu.
Ngati mukudziwa zambiri za ERW, mutha kudina:ERW Round Tube.
LSAW (Longitudinally Submerged Arc Welding)
Kugwiritsa ntchito: Oyenera kupanga awiri lalikulu ndi wandiweyani-mipanda welded mipope zitsulo, ambiri ntchito mkulu-anzanu ntchito monga mafuta ndi gasi mapaipi.
Makhalidwe: Pambuyo popanga mbale yachitsulo mu mawonekedwe a chubu, amawotcherera pogwiritsa ntchito kuwotcherera kwa arc pansi pamadzi mkati ndi kunja panthawi imodzi ya chitoliro chachitsulo.
Ubwino wake: Imatha kunyamula zinthu zokhuthala kwambiri, zowotcherera zabwino, komanso mphamvu zambiri.
Ngati mukudziwa zambiri za ERW, mutha kudina:Tanthauzo la Chitoliro cha LSAW.
Tiyeni tiwone momwe machubu a ERW ndi LSAW amapangidwira!
ERW Pipe Production process
Kukonzekera zakuthupi: Zitsulo zachitsulo zazinthu zoyenera zimasankhidwa ndikusamalidwa kale.
Kupanga: Chitsulo chachitsulo chimapindika kukhala chubu pogwiritsa ntchito chopukutira.
Kuwotcherera: Pakali pano amatenthetsa m'mphepete mwa chingwe chachitsulo ndikupanga weld kudzera pa makina osindikizira.
Kuyeretsa Weld: Kuyeretsa mbali yotulukapo ya weld.
Kutentha mankhwala: Kupititsa patsogolo kamangidwe ka weld seam ndi katundu wa chitoliro.
Kuzizira ndi kukula: Dulani kutalika kwake momwe mungafunikire mukaziziritsa.
Kuyendera: Chitani mayeso osawononga ndikuyesa zamakina, ndi zina.
LSAW Steel Pipe Production Njira
Kukonzekera zakuthupi: sankhani mbale yachitsulo yazinthu zoyenera ndikuchita chithandizo chisanachitike.
Kupanga: Kupanga pogwiritsa ntchito njira yoyenera yokhotakhota mbale yachitsulo kukhala chubu.Njira yomwe imagwiritsidwa ntchito kwambiri ndi JCOE.
Kuwotcherera: Pre-kuwotcherera ikuchitika kukonza mawonekedwe, ndiyeno kumizidwa arc kuwotcherera ntchito kuwotcherera kuchokera mkati ndi kunja nthawi yomweyo.
Kuwongola: Kuwongola kumachitidwa ndi makina owongoka
Kutentha mankhwala: Normalizing kapena kuchepetsa nkhawa ikuchitika pa welded zitsulo chubu.
Kukulitsa: Sinthani kulondola kwapaipi yachitsulo ndikuchepetsa kupsinjika kwamakina.
Kuyendera: Yesani mayeso monga hydraulic pressure test test kuzindikira zolakwika ndi makina.

Longitudinal Welded Steel Pipe Surface Chithandizo
Chitetezo cha Nthawi
Kwa mapaipi achitsulo omwe adzasungidwa panja kapena kutumizidwa panyanja, njira zodzitetezera kwakanthawi zimatengedwa kuti zisawonongeke zisanachitike kapena kukonzedwanso.
Varnish kapena Black Paint: Kupaka utoto wa varnish kapena utoto wakuda kumapereka chitetezo kwakanthawi ku dzimbiri, makamaka m'malo onyowa kapena opopera mchere.Ndi njira yachuma yotetezera kwakanthawi yomwe ndi yosavuta kugwiritsa ntchito ndikuchotsa.
Kukulunga: Chokulungidwa munsalu, chimateteza bwino dzimbiri chifukwa cha chilengedwe, makamaka pakapita nthawi yayitali kapena nyengo yovuta.
Anti- dzimbiri
Chosanjikiza chotsutsana ndi dzimbiri chimapereka chitetezo cha nthawi yayitali kwa chitoliro chachitsulo, kuwonjezera moyo wake wautumiki ndikuwonetsetsa kukhazikika kwake ndikugwira ntchito m'malo osiyanasiyana.
galvanizing: Kupaka wosanjikiza wa zinc pamwamba pa chitoliro chachitsulo kuti zisawonongeke, zinc wosanjikiza zimatha kuperekedwa ku chitetezo cha anode pansi pazitsulo.
Kupaka kwa Epoxy: Zomwe zimagwiritsidwa ntchito poteteza dzimbiri zamkati ndi kunja kwa mapaipi achitsulo.Zimalepheretsa madzi ndi mpweya kuti zisakhudze pamwamba pazitsulo, motero zimalepheretsa dzimbiri.
Polyethylene (PE) zokutira: Kugwiritsa ntchito zokutira kwa PE kunja kwa chitoliro chachitsulo kumagwiritsidwa ntchito kwambiri pamapaipi achilengedwe a gasi ndi mafuta.Chophimbacho ndi chosagonjetsedwa ndi mankhwala, sichimva madzi, ndipo chimakhala ndi chitetezo chabwino pamakina.

Longitudinal Welded Steel Pipe Applications
Amagwiritsidwa ntchito makamaka m'magawo awiri akuluakulu othandizira mamangidwe ndi machitidwe oyendetsa.
Ntchito Yothandizira Zomangamanga
Kumanga mafelemu: Machubu achitsulo aatali kwambiri amagwiritsidwa ntchito ngati mizati ndi mizati muzomangamanga zamakono, makamaka m'nyumba zapamwamba ndi zinyumba zazikulu.
Kumanga mlatho: Machubu achitsulo aatali amagwiritsidwa ntchito ngati ziwalo zazikulu zonyamula katundu za milatho, monga milu ya mlatho ndi ma abutments.
Zothandizira mafakitale ndi mafelemu: Amagwiritsidwa ntchito m'mafakitale olemera, monga petrochemical, kupanga, ndi malo opangira migodi, popanga makina othandizira ndi njanji zachitetezo.
Wind Towers: Machubu achitsulo aatali kwambiri amagwiritsidwa ntchito m'makampani opanga mphamvu zamphepo kuti apange nsanja zopangira ma turbines amphepo, zomwe zimafunikira magawo aatali ndi mphamvu yayikulu kuti athe kupirira katundu wamphepo.
Ma Conveyor Systems
Mapaipi amafuta ndi gasi: Amagwiritsidwa ntchito popanga mapaipi amafuta ndi gasi, mapaipi nthawi zambiri amakhala mtunda wautali ndipo amafuna mphamvu zamakina komanso kukana dzimbiri.
Njira zoperekera madzi ndi ngalande: amagwiritsidwa ntchito kwambiri m'matauni ndi mafakitale amadzimadzi ndi machitidwe opangira madzi otayira, mapaipi achitsulo otalikirapo amagwiritsidwa ntchito kwambiri kuti akhale olimba komanso amatha kupirira zovuta zambiri.
Chemical zoyendera mapaipi: amagwiritsidwa ntchito mu zomera mankhwala kwa kayendedwe ka mankhwala osiyanasiyana, kotalika welded zitsulo chitoliro ali wabwino mankhwala bata kupewa dzimbiri wa sing'anga.
Mapulogalamu a Subsea: Amagwiritsidwa ntchito m'mapaipi popanga minda yamafuta apansi pa nyanja ndi gasi, mapaipi achitsulo otalikirapo ndi oyenera kugwiritsidwa ntchito m'malo ovuta kwambiri chifukwa cha mphamvu zawo komanso kukana dzimbiri.
Ndife apamwamba welded mpweya zitsulo chitoliro wopanga ndi katundu kuchokera China, komanso msokonezo zitsulo chitoliro stockist, kukupatsani osiyanasiyana zitsulo chitoliro njira!
