A302 boiler phaj

 

 

ASTM A302 BO BOILE HLA PHAJ Phaj yog manganbenum thiab Molybdenum-Nickal D. Cov qhab nia A thiab D muaj npib tsib d yog cov tshuaj tiv thaiv. Ntawm lawv, qib C thiab qib D muaj cov tshuaj tsib xee. Nyob rau hauv tib tuab tuab tus mob, cov paib lub zog thiab tensile lub zog ntawm Astm boiler phaj ntawm qib C yog zoo li qub, tab sis elongation qib C phaj yog siab dua.

 

Cov yam ntxwv ntawm Astm A302 lub nkoj siab siab lub nkoj yog raws nws tus manganese-molybdenum-nickel muaj tsawg ntawm cov tshuaj lom neeg muaj pes tsawg leeg.

 

ASTM A302 Siab Ntsev Hlau Hlau Hlau yog dav siv hauv Fabrication ntawm Siab Hlab Hlais, Boilers, Tso Tsheb Hlau Luam thiab Cov Khoom Siv Hluav Taws Xob.
