A333 Qib 6 Tsawg Temp Pipe piav qhia
ASTM A333/A333M-2011 Gr.6 qis- alloy steel seamless yeeb nkab yog tus qauv thoob ntiaj teb feem ntau siv rau cov kav xa khoom thauj khoom hauv ib puag ncig cryogenic. Hom yeeb nkab no nthuav tawm qhov zoo qis- kub toughness thiab tsis kam mus rau hydrogen embrittlement, ua kom muaj kev nyab xeeb ua haujlwm nyob rau hauv huab cua kub ib puag ncig.

Daim ntawv thov
1. Liquefied Natural Gas (LNG) Kev Lag Luam Chain
LNG txais Terminals thiab Cia & Tsheb thauj mus los
Ua ntej-cov kav dej txias thiab Hloov Pauv: Thaum lub sij hawm liquefaction ntawm LNG los ntawm ambient kub mus rau -162 degree, GR.6 steel kav feem ntau siv nyob rau hauv pre-txias seem (xws li seem txias rau -45℃rau -110℃) vim hais tias lawv toughness ntawm -45℃txawm tias qhov kub thiab txias ntawm cov ntaub ntawv no.
Cia Tank Kev Sib Txuas thiab Kev Thauj Khoom / Tshem Tawm Cov Khaub Ncaws: Txuas LNG cov tso tsheb hlau luam rau kev thauj khoom thiab tshem tawm cov khoom siv, cov caj npab no tiv taus ob qho kev cuam tshuam ntawm qis- kub xov xwm thiab ib puag ncig sab nraud, kom muaj kev nyab xeeb kev thauj mus los.
LNG Nkoj thiab Av -Raws li cov chaw
Cov tsheb thauj khoom tuav cov kav dej sib txuas ntawm LNG cov neeg nqa khoom thiab cov kav dej ntawm thaj av -raws li LNG refueling stations ob leeg xav tau cov ntaub ntawv uas tswj cov tawv nqaij ntawm qhov kub thiab txias; GR.6 yog kev xaiv nyiaj txiag thiab siv tau.
2. Cryogenic roj thiab roj Extraction thiab ua
Polar thiab Cold-Cov Roj thiab Roj Thaj Av: Roj thiab roj rho tawm thiab sib sau cov kav dej hauv thaj chaw txias heev xws li Arctic thiab Siberia, qhov chaw sab nraud ambient kub tuaj yeem poob qis dua -50 degree, ua ke nrog qhov kub ntawm qhov nruab nrab (xws li lub cev qhuav dej), xav tau GR.6 los muab kev ruaj ntseg cryogenic toughness.
Subsea Cryogenic Pipelines: Hauv kev sib sib zog nqus- cov roj hauv hiav txwv thiab cov roj tsheb thauj mus los, qee cov kav xa dej yog nyob rau hauv qhov txias heev vim yog qhov kub thiab txias ntawm qhov nruab nrab lossis ib puag ncig hauv qab hiav txwv. GR.6 yog siv los tiv thaiv kev sib txuas ntawm kev kub siab thiab kub qis, thiab nws cov nqi yog siab dua - cov ntaub ntawv qib siab.
3. Muaj tub yees thiab Cryogenic kev sim
Loj -Scale Refrigeration Systems
Kev lag luam tshuaj lom neeg thiab khoom noj khoom haus: Siv rau kev thauj cov tub yees xws li ammonia thiab Freon, nrog rau kev khiav hauj lwm kub qis li -50℃(xws li, ceev-freezing tunnels, cryogenic cia). GR.6 steel kav stably txhawb cov txheej txheem tub yees.
Cryogenic Laboratories: Rau cov kav dej txias hauv particle accelerators thiab cryogenic physics sim cov cuab yeej (xws li kua nitrogen thiab kua argon cua txias tshuab), GR.6 feem ntau yog siv rau ua ntej - cua txias los yog cov yeeb nkab txuas (vim qhov kub siab tshaj yog nyob ze rau lawv tus qauv qhov tseem ceeb, cov tub ntxhais cryogenic seem).
Ice Storage thiab District Cooling: Nyob rau hauv cov dej khov cia cua txias, qhov twg cov tub yees txias (xws li ethylene glycol daws) raug thauj, thiab kev khiav hauj lwm kub yuav qis li -20℃rau -30 degree, GR.6 muab kev nyab xeeb margin.
