Kumvetsetsa Chitoliro cha ASTM A252
M'dziko la zomangamanga ndi zomangamanga, kusankha zinthu ndizofunikira kuti zitsimikizire kukhulupirika ndi moyo wautali wa dongosolo. Chinthu chimodzi chomwe chimalemekezedwa kwambiri pamsika ndi chitoliro cha ASTM A252. Izi ndizofunikira makamaka kwa iwo omwe akugwira ntchito yomanga mulu, chifukwa chimakwirira milu yazitsulo zachitsulo zozungulira.
Ndi chiyaniASTM A252?
ASTM A252 ndi muyezo womwe umafotokoza zofunikira pamilu yamapaipi azitsulo zowotcherera komanso zopanda msoko. Mapaipi awa adapangidwa kuti azigwiritsidwa ntchito ngati mamembala onyamula katundu osatha kapena ngati zipolopolo za milu yoponyedwa m'malo mwa konkire. Izi ndizofunikira kuti zitsimikizire kuti mapaipi amatha kupirira zovuta ndi zolemetsa zomwe zitha kukumana nazo m'njira zosiyanasiyana, makamaka zomangamanga.
TheChithunzi cha ASTM A252mafotokozedwe agawidwa m'makalasi atatu, iliyonse ili ndi zofunikira zosiyana za mphamvu zokolola. Kuchuluka kwa zokolola kumatha kufika ku 450MPa, ndikupangitsa kuti ikhale yoyenera pazinthu zolemetsa monga Bridges ndi nyumba zazitali.
Kukhazikika kokhazikika: Itha kugwiritsidwa ntchito ngati gawo lonyamula katundu wokhazikika kapena chipolopolo cha mulu wa konkriti, kukana malo owononga apansi panthaka.
Kusinthasintha kosinthika: osiyanasiyana m'mimba mwake Φ219mm-Φ3500mm, makulidwe a khoma 6-25.4mm, oyenera mikhalidwe yovuta
Mphamvu zathu zazikulu
Ndi luso lotsogola pamakampani, mphamvu yopanga pachaka yopitilira matani 500,000, ili ndi imodzi mwamizere yochepa yopangira m'mimba yamapaipi achitsulo ozungulira Φ3500mm.
Njira ya submerged arc welding (SAW) imatengedwa, ndipo mtundu wa weld umatsimikiziridwa kudzera pakuyesa kosawononga monga X-ray ndi mafunde akupanga.
Kuwongolera khalidwe lathunthu
Kuyambira zopangira mpaka zomalizidwa, theChitoliro cha Astm A252muyezo umakhazikitsidwa mosamalitsa
Ili ndi epoxy anti-corrosion / 3PE anti-corrosion treatment, yomwe imawonjezera moyo wautumiki m'madera a Marine ndi 30%
Global service network
Zogulitsazo zimatumizidwa kumayiko opitilira 30 kuphatikiza Europe, America, Southeast Asia ndi Middle East
Thandizani kupanga makonda ndikupereka mautumiki amodzi kuyambira pakusankha kupita ku chitsogozo cha zomangamanga
Pazonse, mapaipi a ASTM A252 ndi gawo lofunikira pantchito yomanga ndi zomangamanga, zomwe zimapereka mphamvu ndi kulimba kofunikira pakugwiritsa ntchito zosiyanasiyana. Cangzhou Spiral Steel Pipe Group Co., Ltd. ndiwopanga chitoliro chamtunduwu, chopereka makulidwe osiyanasiyana ndi makulidwe a khoma kuti akwaniritse zosowa za makasitomala athu. Kaya mukugwira ntchito yochulukirachulukira kapena ntchito zina zomanga, kumvetsetsa kufunikira kwa mapaipi a ASTM A252 ndikugwira ntchito ndi wopanga odalirika kudzakhala kofunikira kuti polojekiti yanu ichite bwino.
