ASTM A403 WP304L yeeb nkab haum yog dab tsi?
ASTM A403 WP304L yeeb nkab fittings yog austenitic stainless hlau fittings ua los ntawm tsawg- cov khoom siv carbon 304L, tsim rau siv nyob rau hauv lub siab piping systems, tshuaj txheej txheem kab, thiab khoom noj khoom haus-qib kua hloov daim ntaub ntawv. Lub "L" nyob rau hauv 304L stands rau Low Carbon (Less tshaj los yog sib npaug zos rau 0.03%), uas ho txhim khu weldability thiab txo cov kev pheej hmoo ntawm intergranular corrosion tom qab vuam.
Cov fittings ua raws li ASTM A403 / ASME SA403 tus qauv specifications rau wrought austenitic stainless hlau fittings, npog lub luj tshib.
Fittings ua raws li ASTM A403 WP304L tus qauv:
Lub luj tshib (90 degree, 45 degree, 180 degree)
Sib npaug thiab txo tees
Reducers (concentric / eccentric)
Caps thiab ntu luv
Hla fittings
Custom -ua fittings
Tag nrho cov fittings muaj nyob rau hauv seamless (SMLS) los yog welded (WELD) versions, ua raws li ASME B16.9 thiab MSS-SP-43 dimensional qauv.

Dab tsi yog qhov txawv ntawm ASTM A403 WP304 thiab WP304L?
Qhov sib txawv yog nyob rau hauv cov ntsiab lus carbon. WP304L muaj cov ntsiab lus qis dua (tsawg dua lossis sib npaug li 0.03%), uas ua rau nws zoo dua rau kev siv vuam thiab tiv taus ntau dua rau kev sib tsoo.
ASTM A403 WP304L puas tuaj yeem siv rau siab -kev pabcuam kub?
Yog lawm, tab sis rau kev raug ncua ntev tshaj 425 degree, qib stabilized zoo li 321 lossis 316Ti raug pom zoo rau kev ruaj ntseg carbide zoo dua.
