N’chifukwa Chiyani Muyenera Kusankha Chitoliro cha Chitsulo cha SSAW pa Ntchito?
Oyang'anira mapulojekiti akamakhala pansi kuti afotokoze za makina a mapaipi ngati pali madzi, gasi, kapena chithandizo cha kapangidwe kake, mtundu wa mapaipi nthawi zambiri umakhala chisankho chokhazikika kapena chosweka. Chitoliro chachitsulo cha SSAW—chitoliro cholumikizidwa ndi spiral submerged-arc—chimapitilira kubwera m'makambirano awa pazifukwa zomveka. Koma nchiyani kwenikweni chimachisiyanitsa ndi msoko wowongoka kapena wosanjikizana? Tiyeni tikambirane zoyambira ndikuwona chifukwa chake chitolirochi chapeza malo ake m'mafakitale ambiri.
Kodi kwenikweni ndi chiyaniChitoliro chachitsulo cha SSAW?
Nayi njira yosavuta: opanga amatenga chingwe chachitsulo chopangidwa ndi mpweya wochepa kapena chopanda mpweya wokwanira, n’kuchiyika mu mphero yopangira zinthu pa ngodya yoyezera, n’kuchikulunga kukhala chozungulira, n’kuchilumikiza mozungulira. Njira yozungulira imeneyo si njira yongopeka chabe—ndi imene imalola kuti tizitsulo tachitsulo topapatiza tikhale mapaipi akuluakulu. Taganizirani izi: mukupeza mapaipi akuluakulu popanda kufunika mbale zazikulu, zovuta kuzipeza. Ndiko kugwira ntchito bwino komwe kumapangidwa mu njira yokha yopangira zinthu.
Chifukwa Chake Spiral Weld Ndi Yofunika
Msoko wozungulira sikutanthauza kupanga mapaipi akuluakulu kuchokera ku timizere topapatiza. Pakapanikizika, chotchingira chopingasa chimenecho chimagawa kupsinjika mofanana kuposa chotchingira cholunjika cha longitudinal. Mwachidule,Chozungulira cholumikizidwa ndi chubuimatha kuthana ndi kupsinjika kwakukulu kwamkati ndi makoma opyapyala—pafupifupi makulidwe a khoma ndi 10% mpaka 25% poyerekeza ndi chitoliro chowongoka cholumikizidwa cha mulifupi womwewo. Kwa ogula omwe amawona mtengo wa zinthu, ndalama zenizeni zomwe amasunga popanda kuchepetsa magwiridwe antchito.
Kulondola kwa kukula kwa chinthucho kuyeneranso kutchulidwa. Kulekerera kwa kukula kwa chinthucho nthawi zambiri kumakhala pansi pa 0.12%, kupindika kwa chinthucho pansi pa 1/2000, komanso kupendekera kwa chinthucho mkati mwa 1%. Ogwiritsa ntchito ambiri amapeza kuti amatha kudumpha masitepe owonjezera kukula ndi kuwongola.
Ndani Ali Kumbuyo kwa Chitoliro?
Chitoliro chapamwamba chikufunika unyolo wodalirika wogulira. ZZ Group, yomwe ili ku Yangpu District ku Shanghai, yakhala ikugwira ntchito imeneyi kuyambira kumayambiriro kwa zaka za m'ma 1980. Ndi ndalama zokwana RMB 200 miliyoni zomwe zalembetsedwa, zakula kukhala bizinesi yayikulu yokhudza malonda a zitsulo, kukonza, kugawa, kugulitsa nyumba, ndi ndalama. Amadziwika kuti ndi amodzi mwa mabizinesi otsogola ku China pankhani ya zitsulo, omwe ali ndi maudindo monga "National Steel Trade and Logistics Top 100 Integrity Enterprise" ndi "Top 100 Private Enterprises in Shanghai." Mbiri yotereyi ndi yofunika mukayitanitsa.Chitoliro cha Carbon Steel Weldedza zomangamanga zofunika kwambiri.
Chitoliro chachitsulo cha SSAW chili ndi ubwino weniweni—kugwiritsa ntchito bwino zinthu, mphamvu ya kupanikizika, komanso kulondola kwa magawo—zomwe ma weld owongoka sangagwirizane nazo. Mothandizidwa ndi wogulitsa yemwe ali ndi zaka zambiri zogwira ntchito komanso wodziwika bwino mdziko lonse, ndi kuphatikiza komwe kumagwira ntchito pamakina amadzi, maukonde a gasi, kuyika zingwe, ndi zina zotero. Ngati polojekiti yanu yotsatira ikufuna chitoliro chachikulu chomwe chimagwira ntchito popanda kusokoneza bajeti, chitoliro cholumikizidwa mozungulira ndichofunika kuchiyang'ana kwambiri.
