FAQ
ASTM A790 duplex stainless hlau yeeb nkab yog dab tsi?
ASTM A790 duplex stainless hlau yeeb nkab yog siab -lub zog, corrosion- cov yeeb nkab uas muaj cov khoom siv austenitic thiab ferritic stainless hlau. Nws yog dav siv nyob rau hauv tshuaj lom neeg, roj & roj, marine, thiab industrial daim ntaub ntawv.
Cov qib dab tsi muaj nyob hauv ASTM A790 kav?
Cov qib sib xws muaj xws li UNS S31803, S32205 (tus qauv duplex), thiab S32750 (super duplex) rau huab cua corrosion kuj.
Puas yog ASTM A790 cov kav dej seamless lossis welded?
Ob leeg seamless thiab welded (ERW / LR) kav muaj. Cov kav dej seamless nyiam rau siab - siab thiab cov ntawv thov tseem ceeb, thaum cov kav dej welded raug nqi - siv tau rau cov kab loj dua.
Cov yeeb nkab loj npaum li cas thiab cov sij hawm muaj?
Qhov ntau thiab tsawg ntawm 1/2 "mus rau 24" (DN15-DN600) nrog phab ntsa thickness teem sij hawm los ntawm SCH 5 mus rau SCH 160. Kev cai thicknesses kuj raug tsim.
