Chitoliro chachitsulo ndi dzenje lalitali lachitsulo, lomwe limagwiritsidwa ntchito kwambiri ngati payipi yonyamula madzi, monga mafuta, gasi, madzi, gasi, nthunzi, etc. Komanso, ndi opepuka kulemera pamene kupinda ndi torsional mphamvu ndi chimodzimodzi, kotero amagwiritsidwanso ntchito kwambiri Amagwiritsidwa ntchito popanga mbali zamakina ndi zomangamanga.Amagwiritsidwanso ntchito popanga zida zosiyanasiyana wamba, migolo, zipolopolo, etc. Welded zitsulo mapaipi, amatchedwanso mipope welded, ndi seamed zitsulo mapaipi, amene ndi zitsulo mapaipi opangidwa ndi mbale zitsulo kapena n'kupanga pambuyo crimping ndi kuwotcherera, zambiri ndi seamed zitsulo mapaipi. kutalika kwa 6 metres.Njira yopanga welded zitsulo chitoliro ndi yosavuta, dzuwa kupanga ndi mkulu, pali mitundu yambiri ndi specifications, ndi ndalama zida ndi yaing'ono, koma mphamvu ambiri ndi m'munsi kuposa chitoliro chosasokonekera zitsulo.
Welded zitsulo chitoliro gulu
Amasankhidwa ndi njira yopanga
(1) Malinga ndi ndondomeko - arc welded chitoliro, kukana welded chitoliro (high frequency, otsika pafupipafupi), mpweya welded chitoliro, ng'anjo welded chitoliro.
(2) Malinga ndi weld - molunjika msoko welded chitoliro, mulingo welded chitoliro
Zosankhidwa ndi mawonekedwe a gawo
1
+ nkhani zitsulo mapaipi, etc.
Malingana ndi makulidwe a khoma, akhoza kugawidwa mu: chitoliro chachitsulo chochepa kwambiri ndi chitoliro chachitsulo cholimba;
Malinga ndi mawonekedwe a mapeto, akhoza kugawidwa mu: kuzungulira welded chitoliro ndi wapadera woboola pakati (mabwalo, lathyathyathya, etc.) welded chitoliro;
Kugawa ndi cholinga
General welded chitoliro, kanasonkhezereka welded chitoliro, oxygen-wowomberedwa welded chitoliro, waya chotengera, mitric welded chitoliro, idler chitoliro, deep chitoliro mpope, galimoto chitoliro, thiransifoma chitoliro, magetsi welded woonda-mipanda chitoliro, magetsi welded chitoliro chapadera choboola pakati, scaffold chitoliro ndi spiral welded chitoliro.
Cholinga chachikulu
Amagwiritsidwa ntchito kwambiri mu engineering ya madzi, mafakitale a petrochemical, makampani opanga mankhwala, mafakitale amagetsi, ulimi wothirira, komanso zomangamanga zamatawuni.Ndi imodzi mwazinthu zazikulu makumi awiri zopangidwa ndi dziko lathu.
Amagwiritsidwa ntchito poyendetsa madzi: madzi ndi ngalande.Zoyendera gasi: gasi, nthunzi, mpweya wamafuta amafuta.
Zolinga zomangika: monga mipope yochulukira, ngati milatho;mapaipi a ma wharves, misewu, nyumba zomangira, etc.
Welded zitsulo mipope anawagawa kanasonkhezereka ndi sanali kanasonkhezereka malinga ndi pamwamba mankhwala chitoliro.Mipope yachitsulo yonyezimira imatha kugawidwa m'mitundu iwiri ikachoka ku fakitale: imodzi imakongoletsedwa kumapeto kwa chitoliro, ndipo inayo sichimangirizidwa kumapeto kwa chitoliro.Kwa mipope yachitsulo yokhala ndi ulusi kumapeto kwa chitoliro, kutalika kwa chitoliro chilichonse ndi 4-9m, ndi mapaipi azitsulo opanda ulusi, kutalika kwa chitoliro chilichonse ndi 4-12m.
Welded zitsulo mapaipi anawagawa woonda-mipanda zitsulo mapaipi, unakhuthala mipope zitsulo ndi mapaipi wamba zitsulo malinga makulidwe a khoma chitoliro.Mapaipi wamba achitsulo ndi omwe amagwiritsidwa ntchito kwambiri popanga mapaipi, ndipo kuthamanga kwawo ndi 2.0MPa.Kupanikizika koyeserera kwa chitoliro chachitsulo chokhuthala ndi 3.0MPa.
Pali njira zambiri zolumikizira mapaipi azitsulo zowotcherera, kuphatikiza kulumikizana kwa ulusi, kulumikizana kwa flange ndi kuwotcherera.Kulumikizana kwa flange kumagawidwa mu kugwirizana kwa flange ndi kuwotcherera kwa flange, ndipo njira yowotcherera imagawidwa mu kuwotcherera kwa mpweya ndi kuwotcherera kwa arc.
Ambiri ntchito welded zitsulo chitoliro mfundo osiyanasiyana: mwadzina awiri 6 ~ 150mm
Welded zitsulo mapaipi akhoza ali pafupifupi magawidwe atatu malinga ndi kupanga ndondomeko:
1. Magetsi kukana welded zitsulo chitoliro
Kukana magetsi welded zitsulo chitoliro, English dzina ERW (Electric resistance welded Pipe), weld mtundu ndi msoko wowongoka.Kuwotcherera kukana kumatengera njira yowotcherera yokakamiza popanda zitsulo zodzaza.Palibe kudzazidwa kwa zigawo zina mu weld seam.Khungu zotsatira ndi moyandikana zotsatira za mkulu-pafupipafupi panopa m'mphepete mwa mbale yomweyo usavutike mtima kwa kuwotcherera kutentha, ndi forging aumbike ndi kufinya wodzigudubuza extrusion.Minofu welds.
Kukaniza welded zitsulo chitoliro akhoza kugawidwa m'magulu awiri: mkulu pafupipafupi kukana kuwotcherera HFW (High pafupipafupi welded chitoliro) ndi otsika pafupipafupi kukana kuwotcherera LFW (Low pafupipafupi kuwotcherera).
Mapaipi achitsulo a ERW amagwiritsidwa ntchito makamaka kutengera nthunzi ndi zinthu zamadzimadzi monga mafuta ndi gasi wachilengedwe, ndipo amatha kukwaniritsa zofunikira zosiyanasiyana za kuthamanga kwambiri ndi kutsika.Pakadali pano, ali ndi udindo wofunikira kwambiri pantchito zamapaipi oyendera padziko lonse lapansi.
2. Spiral welded steel pipe
Spiral welded steel pipe, English dzina SSAW (Spiral submerged-arc welding pipe), weld type ndi spiral seam.Njira yowotcherera arc imatengedwa, ndipo magawo awiri amkati ndi akunja amawotcherera.Kuwotcherera kwa arc pansi pamadzi (kuphatikizapo pamwamba pa arc pamwamba pa madzi ndi electroslag surfacing, etc.) ndi njira yowotcherera yofunikira, yomwe ili ndi ubwino wokhazikika wowotcherera, kutulutsa kwakukulu, kulibe kuwala kwa arc ndi utsi wochepa ndi fumbi.
Chitoliro chowotcherera chozungulira chimakhala ndi mainchesi akulu, omwe amatha kufika kupitilira 3000mm, ndipo ndi oyenera kunyamula mapaipi akulu akulu ndi nyumba zomangira.
Zitatu, molunjika msoko welded zitsulo chitoliro
Chitoliro Chotsekera cha Arc Wotalikirapo, dzina la Chingerezi ndi LSAW (Longitudinally Submerged Arc Welded Pipe), ndipo mtundu wa weld ndi msoko wowongoka.Njira yowotcherera arc pansi pamadzi imagwiritsidwanso ntchito, ndipo magawo awiri amkati ndi akunja amawotcherera.Makulidwe a khoma la chitoliro chachitsulo chowongoka ndi chokulirapo, ndipo ntchito yake ndi yofanana ndi chitoliro chachitsulo chozungulira.
Malinga ndi njira zosiyanasiyana zopangira, mipope yachitsulo yowongoka yowongoka imatha kugawidwa m'magulu awiri: UOE (Uing ndi Oing kupanga chitoliro) ndi JCOE (J-ing, C-ing ndi O-ing chitoliro).UOE kupanga njira (U kupanga, O kupanga, E kukulitsa m'mimba mwake), njira yopangira JCOE (mbale yachitsulo imakanikizidwa mu mawonekedwe a J, kenako ndikukankhira mu mawonekedwe a C ndi mawonekedwe O motsatizana, kenako nkukulitsidwa).
Tikumbukenso kuti kumizidwa arc kuwotcherera ndondomeko (SAW) ndi mtundu wa magetsi maphatikizidwe kuwotcherera (EFW Electric Fusion Welded Chitoliro), amene ndi kuphatikiza zitsulo ndi Kutentha zitsulo pakati chimodzi kapena angapo consumable maelekitirodi ndi workpiece.Imodzi mwa njira zomwe arc imasungunuka kwathunthu zitsulo ndi zinthu zodzaza popanda kukakamizidwa, ndipo gawo lazitsulo lodzaza limachokera ku ma electrode.
