ERW ndi chitoliro cholumikizira cholumikizira cholumikizira cholunjika ndi cholimba kwambiri; LSAW ndi chitoliro cholumikizira ...

Kusiyana ndi kugwiritsa ntchito mapaipi achitsulo a ERW, LSAW ndi SSAW

Ma frequency okwera a msoko wowongoka (chitoliro chachitsulo cha ERW) chimagawidwa m'magulu olowetsa ndi kulowetsa ndi kulowetsa molumikizana motsatira njira zosiyanasiyana zolumikizira. Chimagwiritsa ntchito ma coil ozungulira otenthedwa ngati zinthu zopangira. Pambuyo popindika, kupanga kosalekeza, kulowetsa, kutentha, kumata, kuwongola, kudula, chili ndi ubwino wa ma weld afupiafupi, kulondola kwakukulu, makulidwe ofanana a khoma, khalidwe labwino pamwamba komanso kuthamanga kwambiri poyerekeza ndi ozungulira. Komabe, vuto lake ndilakuti mapaipi opyapyala okha okhala ndi mainchesi ang'onoang'ono ndi apakati ndi omwe angapangidwe. Kuphatikizika, zolakwika zonga dzimbiri. Madera omwe amagwiritsidwa ntchito kwambiri pano ndi gasi wachilengedwe wa m'mizinda ndi mafuta osakonzedwa.

Kuwotcherera kwa arc yolumikizidwa molunjika (chitoliro chachitsulo cha LSAW) kumachitika pogwiritsa ntchito mbale imodzi yapakatikati komanso yokhuthala ngati zopangira, kukanikiza (kugubuduza) mbale yachitsulo mu makina opangira nkhungu kapena kupanga, kuwotcherera arc yolumikizidwa mbali ziwiri, ndikukulitsa kukula kwake. Chogulitsa chomalizidwacho chili ndi mitundu yosiyanasiyana ya zinthu, kulimba bwino kwa weld, pulasitiki, kufanana ndi kuchuluka kwake, ndipo chili ndi ubwino wa m'mimba mwake wa chitoliro chachikulu, khoma lokhuthala la chitoliro, kukana kuthamanga kwambiri, kukana kutentha kwambiri komanso kukana dzimbiri. Pomanga mapaipi amafuta ndi gasi amphamvu kwambiri, olimba kwambiri, apamwamba kwambiri, mapaipi achitsulo ofunikira nthawi zambiri amakhala arc yolumikizidwa molunjika yokhala ndi makoma akuluakulu. Malinga ndi muyezo wa API, m'mapaipi akuluakulu amafuta ndi gasi, podutsa m'madera a Gulu 1 ndi Gulu 2 (monga madera amapiri, pansi pa nyanja, ndi madera okhala anthu ambiri), arc yolumikizidwa molunjika ndiyo mtundu wokhawo wa mapaipi osankhidwa. Malinga ndi njira zosiyanasiyana zopangira, imatha kugawidwa m'magulu awa: U0E/JCOE/HME.

Kuwotcherera kwa arc yozungulira pansi (SSAW steel pipe) kumatanthauza kuti pozungulira chitolirocho, njira yake yakutsogolo imakhala pa ngodya (yosinthika) ku mzere wapakati wa chitoliro chopangira, ndipo kuwotcherera kumachitika panthawi yopangira, ndipo kuwotcherera kwake kumapanga mzere wozungulira. Ubwino wake ndi wakuti zomwezo zimatha kupanga mapaipi achitsulo amitundu yosiyanasiyana, zipangizo zopangira zimakhala ndi mitundu yosiyanasiyana yosinthika, kuwotcherera kumatha kupewa kupsinjika kwakukulu, ndipo kupsinjika kumakhala bwino. Choyipa chake ndichakuti kukula kwake ndi kochepa. Kutalika kwa wotchiyo ndikutalika kuposa kwa msoko wowongoka. Ming'alu, ma pores, slag inclusions ndi kusintha kwa welding nthawi zambiri kumachitika. Pa zolakwika zowotcherera, kupsinjika kwa welding kumakhala mu mkhalidwe wopsinjika.

Mafotokozedwe a kapangidwe ka mapaipi amafuta ndi gasi omwe ali kutali amatanthauza kuti arc yozungulira yomwe imayikidwa pansi pa nthaka ingagwiritsidwe ntchito kokha m'madera a Gulu 3 ndi Gulu 4. Pambuyo pokonza njira yopitira kunja, zipangizo zopangira zimasinthidwa ndi mbale zachitsulo kuti zisiyanitse kupanga ndi kuwotcherera. Pambuyo powotcherera ndi kulondola, kukula kwa kuwotcherera kudzakula pambuyo powotcherera kozizira. Ubwino wa kuwotcherera uli pafupi ndi chitoliro cha UOE.
Pakadali pano, ku China kulibe njira yotereyi. Iyi ndi njira yopititsira patsogolo fakitale yathu. Paipi ya "West-East Gas Transmission" imapangidwabe malinga ndi njira yachikhalidwe, koma kukula kwa payipiyo kwakulitsidwa.
Dziko la United States, Japan ndi Germany nthawi zambiri amakana kugwiritsa ntchito SSAW ndipo amakhulupirira kuti mzere waukulu sayenera kugwiritsa ntchito SSAW.
Canada ndi Italy amagwiritsa ntchito pang'ono SSAW, ndipo Russia imagwiritsa ntchito SSAW pang'ono. Apanga zinthu zina zowonjezera zovuta kwambiri. Chifukwa cha zifukwa zakale, mizere yambiri ya trunk ya m'nyumba imagwiritsabe ntchito SSAW. Zipangizozo zimasinthidwa kukhala mbale yachitsulo kuti zikhale zosiyana ndi zolumikizira. Pambuyo polumikiza ndi kulumikiza bwino, kukula kwa welding kudzakulitsidwa pambuyo polumikiza mozizira. Ubwino wa welding uli pafupi ndi chitoliro cha UOE.
Chitoliro cholumikizidwa ndi msoko wowongoka wa ERW nthawi zambiri chimagwiritsidwa ntchito ngati chivundikiro cha waya mumakampani opanga magetsi. Makhalidwe a ntchito: Kuyesa kwa 100% kwa zinthu zoyambira kumaonetsetsa kuti thupi la chitoliro likhale labwino; palibe njira yodulira ma disc omasuka, ndipo zinthu zoyambira zimakhala ndi mabowo ochepa komanso mikwingwirima yochepa; chitoliro chomalizidwa pambuyo pochotsa kupsinjika kwenikweni sichikhala ndi kupsinjika kotsalira; weld ndi yochepa ndipo mwayi wa zolakwika ndi wochepa; imatha kunyamula mpweya wachilengedwe wonyowa pang'onopang'ono; kukula kwa chitoliro chachitsulo kutatha, kulondola kwa kukula kwa geometrical kwa chitoliro chachitsulo kumakhala kwakukulu; welding imachitika molunjika pamalo opingasa pambuyo popangidwa, kotero kusalinganika bwino, kutsegula kwa msoko, ndi kuzungulira kwa m'mimba mwa chitoliro kumayendetsedwa bwino, ndipo mtundu wa welding ndi wabwino kwambiri. Miyezo yogwiritsidwa ntchito ndi zinthu: API 5L, API 5CT, ASTM, EN10219-2, GB/T9711, 14291-2006 ndi miyezo ina yaposachedwa. Magiredi achitsulo azinthu akuphatikizapo: GRB, X42, X52, X60, X65, X70, J55, K55, N80, L80, P110, ndi zina zotero. Zinthuzi zimagwiritsidwa ntchito kwambiri mu mafuta, gasi wachilengedwe, gasi wa malasha, migodi ya malasha, makina, magetsi, kuyika zinthu zina ndi zina. Zipangizo zamakono zamakono: monga W-FF molding, solid high-frequency induction welding, ultrasonic flaw detection, magnetic flux leakage flaw detection, ndi zida zoyesera zapamwamba: monga metallographic analysis, Vickers hardness tester, impact testing machine, spectrum analyzer, universal testing machine ndi zida zina. Zinthuzi zimatumizidwa ku South America, North America, European Union, Southeast Asia ndi malo ena. Kwa zaka zambiri, makasitomala padziko lonse lapansi akhala akuzilandira bwino.

Kampani yathu imaperekaEN10210S235JRH, S275JOH, S275J2H, S355JOH,S355J2H, S355K2H, yokhala ndi zofunikira kuyambira mainchesi akunja 219-1216, makulidwe a khoma 6-40, ndi chitsimikizo choyambirira cha fakitale. Makasitomala padziko lonse lapansi ndi olandiridwa kugula.
