ASTM A333 Qib 1 Tube piav qhia
A333 GR1 cryogenic yeeb nkab yog npib tsib xee- steel dawb, ib hom aluminium-deoxidized zoo-grained cryogenic yeeb nkab, tseem hu ua aluminium-tua hlau. Nws cov haujlwm ua haujlwm yog -40℃txog -101℃. Cov qib steel: A333 GR1, GR3, GR6. Specification: 18-762mm * 2-50mm. Txuj: ASTM A333-2000, thiab ntsuas qhov ntsuas kub tsawg yog ua raws li tus qauv yuav tsum tau ua. Haum rau seamless steel kav siv nyob rau hauv cryogenic siab hlab ntsha thiab cryogenic tshav kub exchangers nrog kev khiav hauj lwm kub ntawm -45℃rau -195 degree.

ASTM A333 GR.1 seamless yeeb nkab kev siv:
1. Kev xa hluav taws xob nruab nrab thiab qis qis
Cheeb tsam cua sov / cua txias Systems
Cov kav dej cua sov hauv thaj chaw txias: Siv los thauj cov dej kub lossis chav dej hauv thaj chaw uas lub caij ntuj no kub tuaj yeem poob mus rau -20℃txog -30℃(xws li Northern China, Northern Europe, thiab Canada), kom ntseeg tau tias cua sov xav tau rau cov neeg nyob hauv thiab kev lag luam. Nws tsis tshua muaj kub toughness tiv thaiv nkig tawg ntawm cov yeeb nkab ntawm qhov kub thiab txias.
Cov kav dej tub yees: xws li ammonia lossis Freon tub yees tshuab hauv cov chaw ua zaub mov thiab cov chaw cia txias, qhov chaw ua haujlwm kub yog feem ntau ntawm -30℃thiab 0 degree, GR.1 steel kav yuav ruaj khov thauj cov tub yees txias.
Roj thiab roj tsheb thauj mus los
Tsis yog-Polar Oil and Gas Field Sectoring Pipelines: Siv rau kev thauj cov roj av, roj av, lossis cov khoom siv roj ua kom zoo nyob rau hauv qhov chaw sov lossis txias (tsis yog-polar), tshwj xeeb tshaj yog tsim rau ntev - cov kav xa dej nyob rau hauv qis- qhov chaw nyob rau lub caij ntuj no.
2. Tshuaj thiab Petrochemical Kev Lag Luam
Cov txheej txheem Cryogenic Media Tsheb thauj mus los: Hauv kev tsim tshuaj lom neeg, qee cov txheej txheem yuav tsum tau ua haujlwm ntawm qhov kub ntawm 0℃thiab -30℃(xws li qee qhov kev sib cais thiab cov txheej txheem tshuaj tiv thaiv). GR.1 steel kav yog siv los thauj cov kua cryogenic los yog roj, xws li kua ammonia thiab ethylene.
Cia Tank thiab cov khoom sib txuas
Txuas cov tank cia cryogenic (xws li kua ammonia cia tso tsheb hlau luam) rau cov cuab yeej tsim khoom, nrog rau ob qho kev cuam tshuam ntawm qhov nruab nrab kub thiab sab nraud qis- qhov kub thiab txias ib puag ncig kom ntseeg tau tias cov kav dej muaj kev nyab xeeb.
3. Lub Tsev thiab Lub Nroog Engineering
Cheeb Tsam Cua Txias / Cua sov Networks
Nyob rau hauv cheeb tsam kub thiab subtropical, GR.1 steel kav yog siv los thauj cov dej txias cryogenic rau lub caij ntuj sov txias los ntawm koog tsev kawm ntawv cov tshuab cua txias; nyob rau hauv cheeb tsam txias, lawv yog siv rau lub caij ntuj no cua sov pipelines.
Lub Tsev Loj HVAC: Tsawg-kub cua txias dej hauv cov chaw lag luam thiab cov chaw tsim khoom lag luam, qhov chaw ua haujlwm kub yuav poob qis dua 5 degree, muaj kev ntseeg siab thauj khoom siv GR.1 steel kav.
4. Marine Engineering
Marine Piping Systems: Roj roj, roj lubricating, lossis cov kav dej txias rau ntawm cov nkoj thauj khoom thiab cov tsheb thauj khoom, tshwj xeeb tshaj yog cov neeg taug kev hauv cov dej txias, yuav tsum tiv taus qis - qhov kub thiab txias los tiv thaiv cov yeeb nkab brittleness.
Offshore Platform Auxiliary Piping: Tsis yog- cov txheej txheem cryogenic cov kav dej nyob rau sab ntug dej hiav txwv roj thiab roj platforms, xws li seawater cooling systems thiab cov khoom cua txias circuits, ua haujlwm nyob rau hauv qhov ntsuas kub ntawm GR.1.
