Welded Steel Pipe
Ma welded steel mapaipi 'nthawi zambiri amawonetsedwa molingana ndi kukula kwakunja ndi makulidwe a khoma, ndipo ndikofunikira kuwonetsetsa kuti kuyesa kwa hydrostatic, kulimba kwamphamvu kwa weld ndi kuzizira kutsata malamulowo.
Mipope yowotcherera yozungulira imatha kupangidwa mokulirapo kuchokera ku timizere tating'ono ndipo nthawi zambiri imakhala yamphamvu kuposa mipope yowongoka ya msoko, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito pamapaipi akulu akulu. The ndondomeko kupanga mtundu uwu welded chitoliro tichipeza kuwotcherera mbale zitsulo kapena n'kupanga atakulungidwa ndi zoumbidwa, ndi kuwotcherera msoko akhoza mwina molunjika kapena ozungulira, malingana ndi ndondomeko kupanga.
Zosinthika
Kuchita bwino kwa ndalama
Mphamvu zapamwamba
Kuchita bwino kwambiri
Spiral welded mapaipi amatha kupanga mipope yayikulu m'mimba mwake pogwiritsa ntchito chitsulo chocheperako, chomwe chimakhala chothandiza kwambiri popanga mapaipi akulu akulu pogwiritsa ntchito zida zochepa.
Poyerekeza ndi kutalika komweku kwa chitoliro chowongoka chowongoka, kutalika kwa chitsulo chozungulira kumawonjezeka ndi 30-100%. Ngakhale kuti liwiro kupanga ndi m'munsi, ambiri a lalikulu m'mimba mwake welded mapaipi ndi ozungulira welded, amene amachepetsa mtengo kumlingo ndi bwino mtengo-mwachangu.
Mphamvu ya ulusi welded chitoliro zambiri apamwamba kuposa chitoliro wowongoka msoko welded chitoliro, ndipo akhoza kupanga welded chitoliro ndi awiri lalikulu kuchokera yopapatiza billet, ndi mkati ndi kunja welded ozungulira kuwotcherera msoko kumawonjezera steeliness, zomwe zimapangitsa chitoliro champhamvu kwambiri.
Kupanga kwa spiral welded chitoliro kumaphatikizapo izi:
Kukonzekera kwa zopangira: ma coil a strip amagwiritsidwa ntchito ngati zida zazikulu zopangira, komanso waya wowotcherera ndi flux zimafunikiranso. Zopangira izi zimayesedwa mwamphamvu ndi thupi ndi mankhwala zisanagwiritsidwe ntchito.
Kuchiza mikwingwirima: Zovala zimasanjidwa, kumetedwa ndikumetedwa musanapangike, komanso kutsukidwa pamwamba ndi kupindika m'mphepete kuti zitsimikizire mtundu ndi kusalala kwa mzerewo.
Kupanga: Mizere imapangidwa kukhala mawonekedwe ofunikira a billet popanga mpukutu woyendetsedwa ndi kunja kapena mkati.
Kuwotcherera: Waya umodzi kapena mawaya awiri omwe ali pansi pamadzi a arc ukadaulo amagwiritsidwa ntchito kuwotcherera billet.
Kuyang'anira Ubwino: Onetsetsani kuti 100% yoyeserera yosawononga ma welds ozungulira. Ngati pali zolakwika, dongosololi lidzangokhala alamu ndi kupopera chizindikiro, ogwira ntchito opanga adzasintha ndondomekoyi malinga ndi chidziwitsochi kuti athetse zolakwikazo mu nthawi.
Kudula ndi kuyendera koyamba: Chitoliro chachitsulo cha kaboni chimadulidwa mu zidutswa zing'onozing'ono pogwiritsa ntchito makina odulira mpweya wa plasma ndipo njira yowunikira yoyamba imachitika. Kuyang'ana koyamba kumaphatikizanso kuyang'ana mawonekedwe amakina a weld, kapangidwe kake, mawonekedwe ophatikizika, mawonekedwe apamwamba a chitoliro chachitsulo ndikudutsa mayeso osawononga. Pokhapokha mutaonetsetsa kuti njira yopangira chitoliro ndiyoyenerera, ingapangidwe mwadongosolo.
Kutsatira: Pamanja akupanga ndi X-ray kuwunika kwa weld komwe kumakhala kopitilira muyeso wamayimbidwe cholakwika chodziwika pa weld. Ngati zolakwika zidapezeka, NDT idachitidwanso mwa kukonza mpaka zitatsimikiziridwa kuti zolakwikazo zidathetsedwa.
Kupanga mapaipi: The rwozungulira welded chitoliromalekezero amapangidwa mwamakina kuti awonetsetse kuti kumapeto kwa perpendicularity, ngodya ya bevel ndi m'mphepete zosawoneka bwino zimayendetsedwa molondola.
APPLICATIONolandiridwa
Kugwiritsa ntchito chitoliro cha spiral welded sikungowonjezera mapaipi otumizira mafuta ndi gasi, komanso kumaphatikizapo ntchito zamadzi, mafakitale a petrochemical, makampani opanga mankhwala, mafakitale amagetsi, ulimi wothirira, zomangamanga zamatawuni ndi zina zambiri. Ntchito zapadera ndi izi: ntchito zamadzi: zoperekera madzi, ngalande ndi zotengera zina zamadzimadzi. Makampani a petrochemical: amagwiritsidwa ntchito ponyamula zinthu zosiyanasiyana zama mankhwala. Makampani a Chemical: monga mapaipi a riyakitala, chosinthira kutentha, nsanja ndi thanki. Makampani amagetsi amagetsi: amagwiritsidwa ntchito popanga mpweya wothamanga kwambiri, chitoliro cha khoma lamadzi ndi zina zotero. Ulimi wothirira: amagwiritsidwa ntchito popanga mipope ya madzi amthirira. Kumanga m'tauni: amagwiritsidwa ntchito popanga zimbudzi, gasi, gasi wachilengedwe ndi mapaipi ena.

Timatumiza makamaka ku South America (35%), Africa (25%), Middle East (20%), Southeast Asia (20%). Mbiri yabwino yamakampani idapangitsa kuti makasitomala athu atikhulupirire. M'madera amenewa, takhazikitsa maubwenzi okhazikika komanso okhalitsa ndi makasitomala ambiri kutengera kukhulupirika kwathu, zinthu zamtengo wapatali, mitengo yabwino, ndi ntchito zowona mtima.
Gulu la Tianjin Lishengda Steel lakhala likutsatira njira zamalonda zapadziko lonse lapansi, kutsatira malingaliro abizinesi omvera mapangano, kusunga malonjezo, ntchito zabwino, komanso kupindulitsana. Ndife okonzeka kugwirizana moona mtima ndi anzathu kunyumba ndi kunja kuti tikhale pamodzi.
