Kumvetsetsa Chitoliro cha ASTM A252
Mu dziko la zomangamanga ndi zomangamanga, kusankha zinthu ndikofunikira kwambiri kuti nyumbayo ikhale yolimba komanso yokhalitsa. Chinthu chimodzi chomwe chimalemekezedwa kwambiri mumakampani ndi chitoliro cha ASTM A252. Chida ichi ndi chofunikira kwambiri kwa iwo omwe akugwira ntchito yopangira zipilala, chifukwa chimaphimba mapaipi achitsulo okhala ndi makulidwe a makoma.
Kodi ndi chiyaniASTM A252?
ASTM A252 ndi muyezo womwe umafotokoza zofunikira pa mapaipi olumikizidwa ndi osapindika achitsulo. Mapaipi awa adapangidwa kuti agwiritsidwe ntchito ngati ziwalo zonyamula katundu nthawi zonse kapena ngati zipolopolo za milu ya konkire yopangidwa m'malo mwake. Izi ndizofunikira kwambiri kuti mapaipi athe kupirira kupsinjika ndi katundu womwe ungakumane nawo m'njira zosiyanasiyana, makamaka kupanga maziko.
TheChitoliro cha ASTM A252Mafotokozedwe agawidwa m'magulu atatu, iliyonse ili ndi zofunikira zosiyanasiyana za mphamvu yokolola. Mphamvu yokolola yayikulu imatha kufika pa 450MPa, zomwe zimapangitsa kuti ikhale yoyenera nyumba zolemera monga Milatho ndi nyumba zazitali.
Kapangidwe kolimba: Kangagwiritsidwe ntchito ngati chinthu chokhazikika chonyamula katundu kapena chipolopolo cha mulu wa konkire, cholimbana ndi malo owononga pansi pa nthaka.
Kusinthasintha kosinthasintha: Kukula kwa m'mimba mwake Φ219mm-Φ3500mm, makulidwe a khoma 6-25.4mm, koyenera mikhalidwe yovuta ya geological
Mphamvu yathu yaikulu
Ndi luso lopanga zinthu lotsogola m'makampani, mphamvu yopangira zinthu yoposa matani 500,000 pachaka, ili ndi imodzi mwa mizere yochepa yopangira zinthu zapakhomo ya mapaipi achitsulo ozungulira a Φ3500mm okhala ndi mainchesi akulu.
Njira yothira arc welding (SAW) yagwiritsidwa ntchito, ndipo ubwino wa weld umatsimikiziridwa kudzera mu mayeso osawononga monga X-ray ndi mafunde a ultrasound.
Kuwongolera khalidwe lonse
Kuyambira zipangizo zopangira mpaka zinthu zomalizidwa,Chitoliro cha Astm A252muyezo ukugwiritsidwa ntchito mosamalitsa
Ili ndi epoxy anti-corrosion / 3PE anti-corrosion treatment, yomwe imawonjezera moyo wautumiki m'malo a m'nyanja ndi zoposa 30%.
Netiweki yapadziko lonse lapansi
Zinthuzi zimatumizidwa kumayiko opitilira 30 kuphatikiza Europe, America, Southeast Asia ndi Middle East.
Thandizani kupanga mwamakonda ndikupereka ntchito zokhazikika kuyambira kusankha mpaka chitsogozo cha zomangamanga
Mwachidule, mapaipi a ASTM A252 ndi gawo lofunikira kwambiri pa ntchito yomanga ndi zomangamanga, zomwe zimapereka mphamvu ndi kulimba kofunikira pa ntchito zosiyanasiyana. Cangzhou Spiral Steel Pipe Group Co., Ltd. ndi kampani yotsogola yopanga mapaipi amtunduwu, yomwe imapereka makulidwe osiyanasiyana komanso makulidwe a makoma kuti ikwaniritse zosowa za makasitomala athu. Kaya mukugwira ntchito yomanga mapulojekiti kapena ntchito zina zomanga, kumvetsetsa kufunika kwa mapaipi a ASTM A252 ndikugwira ntchito ndi wopanga wodalirika kudzakhala kofunikira kwambiri kuti polojekiti yanu ipambane.
