LTCS pipeline yog dab tsi?
LTCS yog cov ntawv luv rau cov pa roj carbon steel yeeb nkab uas tsis tshua muaj kub. LTCS (Low Temperature Carbon Steel) yog siv hauv cov kav dej thaum cov txheej txheem dej kub yuav poob qis dua -20 degree F thaum lub sijhawm ua haujlwm. Tsawg-kub carbon steel feem ntau yog siv rau hauv cov khoom siv kub qis xws li cov nroj tsuag tshuaj hauv qab -55 degree F, tshwj xeeb tshaj yog cov welded siab hlab ntsha.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ASTM A333 / A333M, Standard Specification rau Seamless thiab Welded Steel Yeeb Nkab rau Cryogenic Kev Pabcuam thiab lwm yam kev siv nrog qhov yuav tsum tau ua kom nruj. Nws npog seamless thiab welded steel yeeb nkab siv nyob rau hauv cryogenic tej yam kev mob mus txog rau rho tawm 50 degree F ( rho tawm 45 degree C ).

A333 muaj nyob rau hauv ntau qib, txhua tus siv txoj kev sib txawv steelmaking los txhim kho cov hlau qhov cuam tshuam ntawm qhov kub thiab txias. Qib 1 thiab Grsde 6 raug kuaj ntawm -50 degree F, nrog Gr6 yog qib sib xws.
