Chitoliro cha Chitsulo cha S235 J0 Spiral – Magwiridwe Abwino Kwambiri a Chitoliro Chokulungidwa ndi M'mimba mwake

Chitoliro cha Chitsulo Chozungulira cha S235 J0 – Kugwira Ntchito Kwabwino Kwambiri kwa Chitoliro Chokulungidwa Chachikulu Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Gawo ili la European Standard limafotokoza zaukadaulo woperekera zinthu za kapangidwe kozizira, kopanda kanthu, kozungulira, kozungulira, kapena kozungulira, ndipo limagwira ntchito ku zigawo zopanda kanthu zopangidwa ndi zozizira popanda kutentha.

Tikunyadira kuyambitsa malonda athu apamwamba kwambiri,Chitoliro cha S235 J0 Spiral Steel, yopangidwa kuti ikwaniritse zosowa zomwe zikukula m'mafakitale osiyanasiyana. Monga opanga otsogola pantchitoyi, timagwiritsa ntchito ukadaulo wapamwamba komanso ukatswiri popanga zinthu zapamwamba kwambiri.chitoliro cha mzere yokhala ndi kulimba kwapadera komanso magwiridwe antchito.

Mapaipi athu achitsulo chozungulira amapangidwa ndi zitsulo zozungulira pogwiritsa ntchito njira yolumikizira arc yokhala ndi waya ziwiri zokha. Kudzera muukadaulo wopangira zinthu zotentha nthawi zonse, timaonetsetsa kuti chubu chilichonse chimapangidwa molondola kwambiri komanso mosasinthasintha. Njira yopangirayi yosamala kwambiri imatsimikizira kuti zinthu zathu zikukwaniritsa miyezo yapamwamba kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.

Poyerekeza ndi mapaipi opangidwa mwaluso,Chitoliro chachitsulo chozungulira cha S235 J0 ili ndi zinthu zofunika izi:

A. Pa nthawi yopangira, mbale yachitsulo imasinthasintha mofanana ndipo imakhala ndi mphamvu yochepa yotsalira. Izi sizimangowonjezera moyo wa chitolirocho, komanso zimaonetsetsa kuti pamwamba pa chitolirocho ndi posalala komanso popanda mikwingwirima kapena zolakwika.

b. Njira yathu yapamwamba yolumikizira arc yolumikizidwa mbali zonse ziwiri imalola kulumikiza molondola pamalo abwino kwambiri. Izi zimachepetsa kwambiri kuoneka kwa zolakwika monga m'mbali zosakhazikika bwino, kupotoka kwa ma welding, ndi kulumikiza kosakwanira. Zotsatira zake, mapaipi athu ali ndi khalidwe labwino kwambiri lolumikizira, ndi osavuta kuwongolera ndikuwonetsetsa kuti magwiridwe antchito abwino kwambiri.

C. Ubwino ndiye chinthu chofunika kwambiri kwa ife. Chifukwa chake, timachita kafukufuku wathunthu wa 100% pa chitoliro chilichonse chachitsulo chomwe timapanga. Kuwunika kwathunthu kumeneku kumatsimikizira kuti mapaipi athu akukwaniritsa miyezo yapamwamba kwambiri yamakampani, kukupatsani mtendere wamumtima panthawi yonse yopanga ndi kugwiritsa ntchito.

Ku Cangzhou Spiral Steel Pipe Group Co., Ltd., timanyadira kwambiri kupanga zinthuChitoliro cha S235 J0 Spiral SteelTili ku Cangzhou City, Hebei Province ndipo takhala tikutumikira makampaniwa kuyambira mu 1993. Tili ndi malo okwana masikweya mita 350,000 komanso katundu wonse wa yuan 680 miliyoni, ndipo takhazikitsa maziko olimba a luso labwino kwambiri lopanga zinthu. Gulu lathu lodzipereka la antchito aluso 680 limagwira ntchito molimbika kuti liwonetsetse kuti kupanga zinthu bwino komanso kutumiza matani 400,000 a mapaipi achitsulo chaka chilichonse pa nthawi yake.
