ASTM A333 Qib 1 Seamless Pipe piav qhia
A333 Gr1 alloy yeeb nkab yog ib qho kev pabcuam cryogenic steel yeeb nkab feem ntau siv hauv cov kav dej rau cov cheeb tsam cryogenic, tshwj xeeb tshaj yog tsim rau kev lag luam xws li roj thiab roj. Cov yeeb nkab hlau no muaj qhov ua haujlwm zoo heev, ua kom tawv nqaij, thiab weldability, tswj cov khoom siv zoo nyob rau hauv qhov kub thiab txias (xws li kua nitrogen thiab kua helium), yog li ua kom muaj kev ua haujlwm zoo nyob rau hauv ib puag ncig cryogenic.
Tshwj xeeb, A333 Gr1 alloy yeeb nkab yog dav siv hauv cov roj thiab cov kav dej, cov tshuab ua kom txias, cov khoom siv tshuaj piping, thiab lwm yam kev siv uas yuav tsum muaj kev tiv thaiv cryogenic. Nws daim ntawv thov tsis txwv rau kev thauj mus los ua kua, tab sis kuj tseem siv tau rau kev xa roj. Tsis tas li ntawd, nws cov kev tiv thaiv corrosion ua rau nws zoo heev rau marine engineering, liquefied natural gas (LNG) kev thauj mus los thiab cia, thiab lwm yam.

ASTM A333 Qib 1 Carbon Steel Seamless Yeeb Nkab Daim Ntawv Thov:
1. Kev xa hluav taws xob
Roj thiab roj kis tau tus mob
Cold Region Roj thiab Roj Pipelines: Siv rau kev thauj cov roj av, roj av, lossis cov khoom siv roj ua kom zoo nyob rau hauv cov cheeb tsam uas lub caij ntuj no kub tuaj yeem poob qis dua -20℃(xws li Northern China, Northern Europe, Canada). Nws qhov kub thiab txias toughness tiv thaiv nkig tawg ntawm qhov kub thiab txias.
Liquefied Petroleum Gas (LPG) Pipelines: Qib 1 cov kav hlau steel kom muaj kev nyab xeeb thaum lub sij hawm qis qis ntawm LPG cia thiab kev thauj mus los.
Cheeb tsam cua sov / cua txias Systems
Cheeb Tsam Cov Hluav Taws Xob Hluav Taws Xob: Siv nyob rau hauv cheeb tsam txias rau kev sib txuas chav boiler rau cov neeg siv- kawg cov kav dej kub lossis cov kav dej, tiv taus qhov kub thiab txias.
Cov kav dej tub yees: xws li ammonia lossis Freon tub yees tshuab hauv cov chaw ua zaub mov thiab chaw cia txias, nrog rau kev ua haujlwm kub feem ntau ntawm -30℃thiab 0 degree.
2. Tshuaj thiab Petrochemical Kev Lag Luam
Cryogenic txheej txheem Piping: Qee cov tshuaj tiv thaiv yuav tsum muaj qhov kub thiab txias (piv txwv li, 0℃rau -30℃). Qib 1 steel kav yog siv los thauj cov xov xwm cryogenic (xws li kua ammonia thiab ethylene), ua kom cov kav dej tsis poob ntawm cov txheej txheem kub.
Cia Tank thiab Cov Khoom Siv Txuas Txuas Piping: Txuas cov tso tsheb hlau luam cryogenic (xws li kua ammonia tso tsheb hlau luam) rau cov cuab yeej tsim khoom, nrog rau ob qho kev sib tw ntawm qhov nruab nrab kub thiab sab nraud cryogenic ib puag ncig.
3. Lub Tsev thiab Lub Nroog Engineering
Cov Cuab Yeej Cuab Yeej Cuab Yeej Cuab Yeej Cuab Yeej: Hauv thaj chaw sov lossis thaj chaw sov sov, cov tshuab cua txias hauv nroog yuav tsum tau ua kom txias thaum lub caij ntuj sov. Qib 1 steel kav yog siv los thauj cov dej txias txias.
Cov kav dej kub hauv nroog hauv cheeb tsam txias kom ntseeg tau tias cua sov xav tau nyob rau lub caij ntuj no.
Cov Cuab Yeej Siv Hluav Taws Xob, Qhov Cuab Yeej, thiab Cua Txias (HVAC) Cov Txheej Txheem: Cryogenic cua txias dej hauv cov tsev lag luam loj lossis cov nroj tsuag muaj peev xwm ua haujlwm ntawm qhov kub qis dua 5 degree.
4. Shipbuilding thiab Marine Engineering
Nkoj Piping Systems: Roj roj, roj lubricating, los yog cov kav dej txias rau cov nkoj thauj khoom thiab cov roj tankers, tshwj xeeb tshaj yog cov neeg taug kev hauv cov dej txias, uas yuav tsum tiv taus qhov kub tsawg - ib puag ncig.
Offshore Platform Txheej Txheej Piping: Kev thauj mus los ntawm cov txheej txheem cryogenic tawm ntawm ntug dej hiav txwv roj thiab roj platforms, xws li dej hiav txwv cua txias tshuab thiab txuas cov kav dej rau cov khoom sib cais cryogenic.
