ASTM B338 yog dab tsi?
ASTM B338 yog qhov tseem ceeb thoob ntiaj teb kev qhia tshwj xeeb npog seamless thiab welded titanium thiab titanium alloy raj siv nyob rau hauv condensers nto, evaporators, thiab tshav kub exchangers.
Tam sim no cov khoom siv tam sim no yog ASTM B338-17 (2021), uas suav nrog 28 qhov sib txawv titanium thiab titanium alloy qib. Cov qauv no yog technically sib npaug rau ASME SB-338, lub ntsiab lus cov raj tau lees paub rau ASTM B338 kuj ua tau raws li ASME Boiler thiab Pressure Vessel Code cov cai, ua kom muaj ntawv pov thawj dual rau kev siv dav dav.

ASTM B338 vs ASME SB-338: Dab tsi yog qhov txawv?
Technically: Tsis muaj.
ASME SB-338 zoo ib yam nyob rau hauv tshuaj, mechanical, thiab xeem cov cai rau ASTM B338. Qhov txawv tsuas yog qhov kev siv ntawm kev txiav txim.
ASTM B338 yog hais nyob rau hauv dav dav specifications (roj & gas, desalination, hwj chim).
ASME SB-338yog hais nyob rau hauv ASME Tshooj VIII, Division 1 siab hlab ntsha lis dej num.
